What the user is asking for is a procedural jungle generator with: - Infinite jungle generation (procedural, chunked) - Walking (first-person controls, WASD) - Textures (procedural since we can't reliably load external assets — actually can generate textures via canvas) - Sound (ambient jungle sounds + drone sounds procedurally generated with WebAudio) - Models (procedural trees, drones) - Shaders (custom GLSL for fog, leaves swaying, sky) - Foliage + branches - An AI in an outposts that tries to kill us with drones equipped with an "ELM brain" for shooting (probably means an ML-like brain — implement simple AI: detection, prediction, shooting) - Everything works, optimized, clean syntax This needs to be delivered as a single HTML file (they'll render it in an iframe). Use Three.js from a CDN. Need to include full HTML in a single code block. Key architecture: 1. Three.js via CDN (unpkg or cdnjs). Use a pinned version, e.g. three@0.160.0 module or non-module build. To keep it safe in an iframe, use ES modules with importmap from unpkg or jsdelivr. Actually, the non-module build was removed after r160? The global build `three.min.js` was deprecated around r150 but available until 160? Actually the last UMD build was r147 (removed in r160). Let's use the ES modules with importmap approach — reliable: ```html ``` That works fine in an iframe. Core systems: **Terrain**: Chunked heightmap via value noise (fBm), deterministic hash from seed. Ground rendered as per-chunk PlaneGeometry, vertices displaced, colors from vertex colors (variation of moss/dirt). Chunks load/unload around the player (e.g., radius 3-4 chunks of 64m each). Height query function reused for walking (player Y = terrain height) and tree placement. **Trees**: InstancedMesh per chunk for trunks + canopies (or merged geometry). Use deterministic RNG from chunk coordinates, generate trees with seeded RNG per chunk. Trunks: cylinder with slight bend; branches: small cylinders — but to keep performance, build one merged "tree" geometry template (a few variants), and use InstancedMesh with per-instance matrices. Leaves: cones/icosahedron blobs, or custom shader planes. Sway shader via onBeforeCompile or ShaderMaterial injection on leaves — vertex displacement by sin(time + worldpos). **Foliage**: Grass/ferns as instanced crossed planes with alpha-tested texture (procedurally generated on canvas) and sway shader. **Textures**: Generated on canvas: bark, leaf/fern blades, ground moss, sky? Use CanvasTexture. **Sky**: Large sky dome with gradient + sun via shader, plus fog matched to the sky color. Add godrays-ish light shafts? Keep it simple: shader skydome + fog. **Sound**: WebAudio — ambient: filtered noise (wind/rustle), random bird chirps (oscillator sweeps), drone hums (oscillators whose gain/volume depends on distance), gunshot sound (noise burst), player hit sound. Must start after user gesture (click to start). **Outpost + drones AI**: An outpost structure placed at some distance (a fixed offset from spawn based on seed, e.g., 120m away). Drones spawn from the outpost, AI states: PATROL, SEARCH, ENGAGE. The "ELM brain" — an aiming module: tracks the player, predicts lead based on player velocity, adds noise/error that decreases while tracking, fires tracers/bullets when angular error is small and line of sight is clear. Player has health; drones can be destroyed by player's shooting (click to shoot with a simple hitscan rifle). Score/kill counter. Drone respawns from the outpost over time. Drones have rotor animation, point light, engine sound. **Player controls**: Pointer lock, WASD, Shift sprint, Space jump with gravity, terrain collision via height function. Weapon view model (simple box gun) + muzzle flash. Hitscan raycast against drone bounding spheres. **Optimization**: - InstancedMesh everywhere, chunk culling by distance, frustum-friendly. - Single material with vertex colors. - Fog for culling illusion, clamp far plane. - Reuse geometries/materials globally; dispose chunks on unload. - Cap pixel ratio, resolution scaling if FPS low maybe (adaptive) — keep simple: clamp pixelRatio at 1.5. - No shadows, or one cheap directional shadow? Shadows on infinite terrain are expensive; fake it with blob shadows? Skip real shadows; use hemispheric lighting + baked AO-ish vertex darkening under canopy. Maybe enable cheap shadow only for drones? Simpler: no shadow maps; use a gradient texture and vertex AO. HUD: health bar, ammo, drone count, compass, crosshair, damage vignette, minimap? Keep it to HUD with crosshair, health, kill counter, distance to outpost, warnings. Let me design the code carefully to ensure correctness. This is a large build; aim for well-organized single file, commented, sections. Noise: implement hash-based 2D value noise + fBm. ```js function hash2(x,y){ ... deterministic } ``` Use something like: ```js const SEED = (Math.random()*1e9)|0; // or fixed function h2(x, y){ let n = x*374761393 + y*668265263 + SEED*144665; n = (n ^ (n>>13)) * 1274126177; n = (n ^ (n>>16)); return (n>>>0)/4294967295; } ``` Need to be careful with 32-bit overflow in JS — use Math.imul for multiplication to keep it in int32. ```js function h2(x, y){ let n = Math.imul(x, 374761393) + Math.imul(y, 668265263) + Math.imul(SEED, 1440615) | 0; n = Math.imul(n ^ (n >>> 13), 1274126177); n ^= n >>> 16; return (n >>> 0) / 4294967296; } ``` Value noise with smoothstep interpolation: ```js function vnoise(x, y){ const xi = Math.floor(x), yi = Math.floor(y); const xf = x - xi, yf = y - yi; const u = xf*xf*(3-2*xf), v = yf*yf*(3-2*yf); const a = h2(xi,yi), b=h2(xi+1,yi), c=h2(xi,yi+1), d=h2(xi+1,yi+1); return a + (b-a)*u + (c-a)*v + (a-b-c+d)*u*v; } function fbm(x,y,oct){ let s=0, a=0.5, f=1; for(...){ s+=a*vnoise(x*f,y*f); f*=2; a*=0.5;} return s;} ``` Terrain height: ```js function terrainH(x,z){ let h = fbm(x*0.012, z*0.012, 4) * 14 - 4; // rolling hills h += fbm(x*0.06, z*0.06, 2) * 1.2; // Flatten river paths maybe: use ridge return h; } ``` Also a river/clearing mask via a noise threshold that produces open ground. Chunks: CHUNK = 48 (meters), SEG = 24 segments (2m per segment). VIEW_R = 3 chunks => 7x7 = 49 chunks ground mesh, each 24x24*2 triangles ≈ 1152 tris*49 ≈ 56k tris — fine. Per-chunk content: trees (InstancedMesh trunks, InstancedMesh canopy, maybe InstancedMesh branches merged into trunk geometry), foliage instances (grass tuft instanced mesh), rocks (few). Store in a Chunk object with dispose. Tree generation: deterministic count from h2(cx,cz)*density. Positions from seeded rng stream: use h2 with salt index to be deterministic per chunk: rand(i) = h2(cx*57+i, cz*91+i)... actually simpler: create a mulberry32 seeded with hash of chunk coords: ```js function mulberry32(a){ return function(){ a|=0; a=a+0x6D2B79F5|0; let t=Math.imul(a^a>>>15, 1|a); t=t+Math.imul(t^t>>>7,61|t)^t; return ((t^t>>>14)>>>0)/4294967296; } } ``` Tree variants: pre-build 3 template geometries (trunk with branch merged; canopy blobs merged). Build with BufferGeometryUtils? Avoid extra imports; write a small mergeGeometries that concatenates position/normal/uv/index arrays. Actually three's examples have BufferGeometryUtils but importing adds complexity; write a small merge function (non-indexed merge is easiest: convert toNonIndexed and concatenate). Write `mergeGeo(list)` that does toNonIndexed and concatenates attributes. Fine. Trunk template: tapered cylinder (radiusTop small), plus 3-5 branch cylinders placed and rotated randomly — but template must be deterministic; build with local rng (fixed seed per variant so consistent). Canopy template: a few icosahedron blobs at top around branch tips, flatten vertices randomly for an organic look. Leaves material: MeshLambertMaterial with vertexColors? Add sway by onBeforeCompile injection into Lambert material: displace vertex by wind. Simplest: onBeforeCompile on leaves material, add uniform uTime, modify `#include `: ``` transformed.x += sin(uTime*1.5 + position.y*0.5 + (instanceMatrix? ...)) ... ``` For instanced mesh, in Lambert shader `instanceMatrix` is available when USE_INSTANCING is defined. We can compute a phase from instanceMatrix[3].xz. ``` float ph = instanceMatrix[3][0]*0.35 + instanceMatrix[3][2]*0.5; transformed.x += sin(uTime*1.7+ph + transformed.y*0.15)*0.12*smoothstep(2.,8.,transformed.y); ``` Wait, transformed is local; the sway amount should scale with height in local space. Good. Foliage texture: draw fern/fronds on canvas with alpha, alphaTest 0.5, side DoubleSide, use MeshLambertMaterial with map. Foliage sway similarly, with a smaller amount, alpha-tested. Ground material: MeshLambertMaterial with vertexColors + procedural moss/dirt texture (canvas noise). Repeat texture with uv scaling. Lighting: hemisphere light (sky greenish), directional sun (no shadow for perf; or enable cheap shadow? Skip), plus fog THREE.FogExp2 color matched to sky horizon. Sky: large sphere with ShaderMaterial gradient: horizon warm haze → teal-green zenith; sun disc glow in sun direction. BackSide, fog:false, follows camera. Fireflies/particles: floating pollen/spore points for atmosphere — cheap Points with shader or PointsMaterial with texture, animated drift. Adds motion. Rain? No, keep scope. **Drones**: Build a drone mesh: body (box/octahedron), 4 arms + rotor discs (spinning), red eye light, small gun. Group per drone; max ~6 active. Drone behavior (per-drone state machine): - Patrol waypoints around the outpost ring, or hunt the player position with noise offset. - Detection: distance < detectRange (60m) AND line-of-sight-ish (skip heavy raycast; use pseudo-occlusion by sampling terrain height between? Cheaply: sample points along ray vs terrainH, if terrain above ray then occluded). Feasible: 8 samples. - ENGAGE: strafe/orbit player at ~18-28m, altitude = terrain+6..10. ELM brain aim: maintain smoothed aim vector toward predicted player position: pred = playerPos + playerVel * lead (lead = dist/bulletSpeed). Error decreases with lockTimer; fire burst when angle error < threshold and cooldown done. Bullets: drone bullets are projectiles (visible tracers) with velocity, check collision with player each frame as sphere distance (radius 0.7). Muzzle flash + sound (scaled with distance). - Player damage: health 100, regen after 5s of no hits. Damage vignette flash, screen shake. - Drone HP 30 (3 hits from player rifle). Death: fall + explode particles + sound, respawn timer at outpost after delay, kill++. **Outpost**: Tower at fixed world position (e.g., seeded direction at 140m from spawn): base cylinder, antenna, glowing red "eye" beacon, dish. Spawns drones. If player shoots the core enough times outpost can be destroyed (win state: "OUTPOST NEUTRALIZED") — good win condition. Core HP 60. Then drones stop respawning; remaining drones die or continue. Player shooting: hitscan raycast against drone bounding spheres + outpost core sphere. Tracer line (fading Line). Rifle ammo 30, reload R, actually infinite reserve. Muzzle flash light + gun recoil animation. **Sound** (all WebAudio generated): - Master gain, start on click. - Ambient: looped noise buffer through lowpass for wind; periodic bird chirps: schedule random chirp (osc freq sweep 2-4kHz) every 2-7s; occasional distant "howler" low moan. - Drone hum per drone: sawtooth + LFO, gain by distance. Create/destroy on spawn/death; or one global hum per drone object with panner? Use StereoPanner based on relative x. Keep simple: per-drone gain node, update each frame. - Gunfire: noise burst + low thump. Drone shot: higher pitched zap. Hit: thud. Explosion: filtered noise decay. Damage taken: low pulse. - Footsteps: soft noise tap on walk cycle. **HUD**: DOM overlay: crosshair (CSS), health bar, ammo, drone threat indicator, distance to outpost, kill count, messages ("DRONE DETECTED", "OUTPOST CORE EXPOSED"), damage vignette div, start screen (click to lock pointer + start audio), death screen with respawn. Optimizations & correctness notes: - Clamp dt. - Reuse tmp vectors. - Chunks: Map key "cx,cz"; on unload dispose geometries (shared geometries? For trees we share template geometries across chunks! InstancedMesh can share geometry+material; on chunk removal, only instanced mesh is disposed (instanceMatrix buffer). Ground geometry is per-chunk (unique) → dispose. - Update loop budgeted: drone AI decisions staggered. - renderer.setPixelRatio(min(devicePixelRatio, 1.5)). Pointer lock: click on start overlay → canvas.requestPointerLock; on lock lost show pause overlay. Jump/gravity: vy -= g*dt; ground clamp: if y < h+eye then land. Movement relative to yaw; simple: no tree collision (fine), maybe push away from trunk? Skip for perf — actually simple radial push against nearest tree would need spatial data; skip. Sun direction fixed; fog color like #9fbf8f hazy jungle. Add godray-esque light shafts? Could add some additive cone meshes near sun — skip; instead, floating dust + canopy sway + bird calls will sell it. Also add a falling-leaf particle system near player (Points, drift). Good motion. Water? Maybe small ponds where terrain low: color vertices bluish below threshold, plane of water at height -2.2 for large water surface with shader ripple? Simplification: add one big water plane at y = -2.4 covering view area that follows player (semi-transparent, fake normal animation with onBeforeRender? Keep simple MeshPhongMaterial with opacity + slight vertex wave shader). Nice touch, cheap. terrainH min ~ -4 so low areas become ponds. Let me tune: base hills -5..+10, water level -1.5. Water: plane 400x400 follow camera, custom shader or Lambert with transparency + moving canvas texture normal-ish — simplest: MeshPhongMaterial color #1c3f38, transparent .75, plus slight sin offset for y in shader? Static water with sun specular is fine; add onBeforeCompile ripple in vertex for subtle uv scroll and shimmer in fragment? Keep modest: opacity + high shininess + subtle texture. OK. Bullet from drone: pooled array of small stretched box/sprite tracer with additive material; move; hit test against player capsule (distance to player position < 0.8 → damage 8-12); lifetime 2s; collide with terrain (y < terrainH → puff). Player tracer: instant hitscan with visual line fading from muzzle to hit point/distance. ELM brain module — name it `ELM` (Engagement & Lead Module) in the code: per drone: `elm = { lock: 0, err: 1.5, aim: Vector3 }`, update: target = predicted position; lock grows when LOS; err = baseErr * (1 - lock); fire when angleDiff < err and cooldown<=0 and dist to fonts.googleapis: display font "Chakra Petch" or "Orbitron" for HUD + "IBM Plex Mono" for data. Jungle + military HUD: "Saira Condensed"/"Big Shoulders"? Let's use "Big Shoulders Display" for titles, "Space Mono" or "IBM Plex Mono" for body. Pick: title 'Big Shoulders Display' (700/900), UI 'IBM Plex Mono'. Military-tactical vibe. Colors: jungle green + warning amber/red. HUD accents: #ffb454 amber and #ff4444 threat. Start screen: title "VERDANT PROTOCOL" / "JUNGLE∞", control list, click to deploy. Background: the live canvas already rendering behind (nice). Overlay is dark green translucent with scanlines? Keep tasteful. Now, code structure in the module script: 1. Constants & helpers (RNG, noise, terrain) 2. Renderer/scene/camera/lights/fog/sky/water 3. Textures (canvas generation: bark, leaf, moss, glow, particle) 4. Geometries & materials templates (tree variants, fern, rock) 5. Chunk system (build/dispose/update) 6. Player (controls, physics, weapon) 7. Audio engine 8. Drone AI + ELM + bullets 9. Outpost 10. Particles (pollen, falling leaves, explosions) 11. HUD binding 12. Main loop Careful: pointer lock in iframe needs `allow="pointer-lock"` maybe — out of our control; it usually works with iframe embed default? The embedder controls that. Just implement; mention nothing (they said no mentioning the iframe). Let me write the sky shader: ```glsl varying vec3 vDir; // vertex: vDir = normalize(worldPos); // frag: vec3 dir = normalize(vDir); float h = clamp(dir.y, -0.2, 1.0); vec3 zen = vec3(0.35,0.55,0.45); // teal-ish? actually jungle haze: zenith #7fb069? ``` Better: zenith #4e7d5e? Sky above jungle: warm pale. Choose: horizon #d8e0b8 warm haze, zenith #7ba7bc soft blue-green, sun glow warm #fff2c0. Fog color matches horizon-ish #cfd8b0. Tuning: fog like #b8c69a-ish. Sun direction: normalize(0.55, 0.65, -0.35). Ground color: moss green variations #3c5a2f..#5c7a3a, dirt patches #6b563a via vertex color mixed by noise; texture adds detail. Canopy color: vary per instance? Use material color + slight variation per variant material (3 green tones). Use vertex colors in canopy blob: darken bottom vertices (fake AO) — set color attribute with darker underside. Trunk bark texture: canvas 128x128 with vertical noisy streaks browns. Fern texture: 128x128 transparent, draw 5-7 leaves radiating from bottom-center? Crossed plane foliage: texture is a single tuft: multiple leaves from bottom. alphaTest .45. Grass instancing: crossed planes geometry (two quads X), ~ per chunk N=140 within open areas, scale random. Plus larger ferns less count. Rocks: icosahedron detail 0, squished, grey-green, few per chunk. Also add hanging vines? Cheap way: instanced thin cylinders drooping from canopy — could complicate. Instead, add "liana" texture plane? Skip; branches + ferns + trees + grass is enough. Actually drooping vines add jungle feel: build a vine geometry: thin tapered box strip with curve, instanced under canopies with sway. Might reuse grass sway shader. Try: vine geometry: plane strip 0.18 wide × 4-7 long, subdivided vertically, bend slightly with x offset by curve; texture = leaf-strip alpha. Instance at canopy positions with random rotation, hang from top. Since canopy positions are known at chunk build (we computed tree positions + heights), place vines at (x, topY-?, z) with random offset. Count ~2/tree for some trees. Sway shader pivots top: displacement grows toward bottom ((1 - uv.y)). Nice. Manage per-chunk InstancedMesh count: compute placements first into arrays, then create InstancedMesh with exact count. Trees per chunk: density from low-freq noise (grove vs clearing) ~(h2 based) 10-22. Chunk 48m → ~ up to 22 trees, view 7x7=49 chunks → up to ~1000 tree instances split across many InstancedMeshes (49*3 draw calls for trunk/canopy/vines + 49 for foliage + 49 ground + water + sky + drones) ≈ ~250 draw calls. Hmm, 200+ draw calls but each is trivial; should still be OK on most machines. We could reduce chunks: VIEW_R=3 → diameter 7. Fine. Actually to reduce draw calls, merge grass+fern? Different materials. It's fine — modern GPUs/Three handle 250 simple calls at 60fps. Adaptive quality: measure FPS; if avg < 45 for a while, reduce pixel ratio to 1 and foliage density multiplier (rebuild? just reduce new chunk density). Implement lightly: pixel ratio step-down. Also `renderer.info` maybe show stats in HUD? Add small fps counter (dev-y flavor). Sure, small. Player weapon view model: group attached to camera: simple rifle built of boxes, dark metal + wooden-ish; bob on walk, recoil kick on fire, muzzle flash quad (additive sprite) toggled briefly + PointLight flash (one light, short-lived) — OK. Reload: R key, 1.2s, sound click. Ammo: magazine 30, reserve ∞. Show "30 / ∞". Drone bullets vs terrain and player. Player bullet is hitscan vs drone spheres (r=1.4) and core sphere (r=3) — pick nearest hit within 200m. Also terrain hit → spawn dirt puff particle + decal? Just puff. Particle system: one Points pool (e.g., 512) with position/color/life arrays, update on CPU; material with vertexColors + size attenuation + soft circle texture. Use for explosions, hit puffs, muzzle smoke. Good. Falling leaves: separate small Points (128) recycled around player, drift with wind sin. Pollen motes: 200 points additive faint, drift slowly, catch sunlight — nice ambient motion. Death screen: "YOU WERE MULCHED" haha; keep tone: "SIGNAL LOST — Drone grid prevails". Respawn button → click re-locks. Messages feed: fading stacked toasts top-right: "UPLINK: OUTPOST LOCATED — bearing 214°", "ELM brain online — drones dispatched", etc. Also threat indicator: when a drone has LOS on us, red "TRACKED" blink + geiger-like tick sound? Maybe subtle beep on lock increase — nice: beep rate ∝ lock. Implement simple. Compass ribbon: div with markers positioned by (bearing - yaw). Simpler: rotate a long strip containing letters N E S W + outpost icon with transform translateX. Width strip covers 360*px; wrap-around: duplicate labels. Manageable: build a strip spanning -360..720, position = -((yawDeg%360)+360)%360 * pxPerDeg + center. Outpost marker similarly. pxPerDeg ~ 2.2. OK, write everything carefully. Let me draft the major code with attention to correctness. RNG/noise: ```js const SEED = 1337; // fixed for reproducibility? Or random per load: (Math.random()*2**31)|0 — random makes outpost placement vary; keep random but compute outpost direction from seeded rng. Random per load fine and keeps "generator" feel. ``` Use random seed per load. ```js function h2(x, y){ let n = Math.imul(x|0, 374761393) ^ Math.imul(y|0, 668265263) ^ SEED; n = Math.imul(n ^ (n >>> 13), 1274126177); n ^= n >>> 16; return (n >>> 0) / 4294967296; } ``` vnoise/fbm as above. terrainH: ```js function terrainH(x, z){ let h = (fbm(x*0.013+3.1, z*0.013-7.7, 4) - 0.42) * 22; // rolling -9..+12 h += (fbm(x*0.09, z*0.09, 2) - 0.5) * 2.2; // detail const ridge = Math.abs(fbm(x*0.02+9.2, z*0.02+4.4, 3)-0.5)*2; h += ridge*ridge * 6; // occasional rises return h; } ``` Range roughly -10..+20. Water level WL = -3.0. Flatten near spawn? Ease spawn: smooth to 0 near origin with t = clamp(1 - dist/30). Add: ```js const d = Math.hypot(x,z); if(d<40){ h = h*(d/40) } // gentle bowl? Actually flatten: h *= smoothstep? ``` Use h *= s where s = min(1, d/45). Makes spawn nearly flat at 0. But ground height 0 vs water -3 fine. openness(x,z) for density: `fbm(x*0.02+50, z*0.02-20, 3)`; high openness → clearing (less trees, more grass). Also no trees below water+0.5. Chunk build: ```js const CHUNK=48, SEG=32, VIEW=3; // diameter 7x7 class Chunk{ constructor(cx,cz){...build...} dispose(){...} } ``` Ground geometry: PlaneGeometry(CHUNK, CHUNK, SEG, SEG) rotated -PI/2, then set y per vertex to terrainH(wx, wz), compute normals, set colors. Vertex colors: moss base mix by noise + darker where slope steep? Slope from normal after computeVertexNormals — compute colors after normal: use normal.y. Ground texture: 256 canvas with moss noise speckle, wrap repeat 3 times per chunk. Trees: count = floor(lerp(6, 26, density)), density = clamp(1.2 - openness*1.4 ...). Compute rng = mulberry32(h2(cx*7+1, cz*13+2)*2**32). For each tree i: pick x,z in chunk; skip if in water or too close to outpost clearing? Also outpost area clear radius 18. y = terrainH. Scale s = 0.8+rng*0.8. Variant v = rng*3|0. InstancedMesh: trunksIM (geometry variant) — since variants differ, group instances per variant: collect matrices per variant (3 variants), create InstancedMesh per variant that has >0. Similarly canopy. To keep draw calls bounded: max 3 trunk IM + 3 canopy IM + vine IM + grass IM + fern IM + rock IM + ground per chunk ≈ 10 * 49 = 490 draw calls — too many. Reduce: single merged tree geometry per variant with trunk+branches (1 material, bark) and canopy is separate material (leaves) — need separate material for leaves sway/color. Keep max 2 variants to reduce: 2 trunk + 2 canopy. Or further: bake vertex colors into one geometry and use single material with vertexColors for trunk+branches (bark texture + vertex color tint). And canopy single geometry variant with vertex color (green tint + AO), 1 material with sway. So per chunk: max 2 trunk variants IM + 2 canopy IM. Let's use 2 variants. Draw call estimate per chunk: ground 1, trunks ≤2, canopy ≤2, vines 1, grass 1, ferns 1, rocks 1 = ≤8 → worst 392. Hmm still many but most chunks are smaller; also 49 chunks * ~6 average = ~300. Might be heavy on low-end but generally OK (each call tiny). Alternative: reduce VIEW to 2 (5x5=25 chunks) with fog hiding distance: CHUNK 56, VIEW 2 → 280m cover, fog 140. Fewer calls (~150). Let's do CHUNK=56, SEG=28, VIEW=2 (5x5 = 25 chunks, radius 140m cover), fog density ~0.011 (visibility ~150m). Good perf + looks infinite. Also adaptive: skip far grass if low FPS. Instance matrices: composed with position, rotationY, scale. Slight tilt for trees too. Canopy geometry template: 4-6 icosahedron(1.6,1) blobs at positions around (0, h, 0), h = trunk height (~7-10), randomly offset, scaled; vertex colors: base green tint with darker underside (color *= lerp(0.55, 1, based on local y/normal)). Non-indexed merge. Trunk template: CylinderGeometry(rTop=0.16, rBottom=0.55, H=9, 7 seg), translate y H/2, add 4 branches: thin cylinders (0.09→0.16, length 2.5-3.5) placed at height 0.55-0.85 of H, rotated outward/downward ~-20..-45°, positioned at trunk surface. Merge. UV: cylinder uv fine for bark repeat. Vertex color on bark: slight variation — set color attribute with constant 1 for merged (tint via instance color? Does InstancedMesh support setColorAt? Yes, instanceColor). Use instanceColor for tint variation! Nice: setColorAt with slight hue variation per instance. Material must have vertexColors false but instanceColor works automatically in Lambert. Yes, three r160 supports instanceColor with built-in materials. Same for canopy, instanceColor greens vary. Grass geometry: two crossed planes 1.1×1.1 with leaves texture; per chunk ~220 instances where openness high and above water; instanceColor varies green; sway shader with stronger amount at top (uv.y). Fern: bigger cross plane 2.2 with fern texture, ~40 per chunk in shade (density area). Vines: as described; geometry: PlaneGeometry(0.35, L=5, 1, 6) bend: x = sin(vy*2)*0.3? Build manually in code per template. Sway pivot top: displacement *= (1 - vUv.y). Place top at canopy: y = treeY + H*0.8, random offset radius 1.5. Count ~1-2 per ~50% of trees. Material leaves texture with strips of leaves alpha: reuse fern texture? Draw separate "vine" canvas: vertical leaves along a stem. OK. Rocks: Icosahedron(1,0) non-uniform scaled, grey-green, ~4/chunk. Chunk dispose: remove meshes from scene; dispose per-chunk geometries (ground geo); instanced meshes share template geo/material — but InstancedMesh has its own instanceMatrix buffer; call mesh.dispose() (does InstancedMesh.dispose exist? InstancedMesh has dispose that disposes instance attributes? Actually InstancedMesh.dispose() disposes instance attributes? It has a dispose method added in r15x. Yes InstancedMesh.prototype.dispose exists (disposes instance buffer). Call im.dispose() safely + scene remove. Shared geometry/material persists. Good. Update: compute needed chunk set from player pos each frame (or every 0.25s); build missing (budget max 2 builds per frame to avoid hitch), remove out-of-range (dispose). Tree placement also must avoid overlap with outpost clearing and spawn clearing: check dist to those < R then skip. Outpost placement: dir = angle from seeded rng; position at distance 150 from origin: OP = (cos(a)*150, terrainH, sin(a)*150). Flatten terrain around it? Terrain there is unknown; build outpost with legs adapting: base y = terrainH at its position; tower from that. OK. Drones orbit around it. LOS check function: ```js function hasLOS(ax, ay, az, bx, by, bz){ const steps = 7; for(let i=1;i y + 0.3) return false; } return true; } ``` Trees also occlude but ignore (foliage not solid) — acceptable; note it's "canopy-penetrating sensors" 😄. Drone update (budget: update all, cheap): ```js state: 'patrol' | 'engage' patrol waypoint: ring around outpost radius 40-70, or if player within detect 55 and LOS → engage. engage: desired orbit point: angle around player changes (orbitDir), radius 16-24 (keep), altitude terrain+6..9 or player.y+4. steering... ELM: predict = ppos + pvel*(dist/90) (drone bullet speed 90); aimCurrent lerp toward aimTarget with rate 3+lock*4; lock += dt*0.5*aggro when LOS else lock = max(0, lock - dt*1.5); err = (1.6 - lock) rad? Use angle threshold: fire when angleBetween(aimDir, droneForward?) — simpler: compute direction from drone muzzle to predicted; fire when angle between smoothed aim and ideal direction < 0.05+? Actually fire condition: lock > 0.7 && LOS && dist<80 && cooldown<=0. Add dispersion: actual shot direction = idealDir + random cone * (0.09*(1.1-lock)). That gives fair misses early. Burst: 3-4 shots 0.09s interval, cooldown 1.4-2.2s. ``` Drone hit reaction: on hit, add impulse + lock *=0.5, flash white emissive. Drone death: state 'dead': spin, fall with gravity, on ground → explode, remove, schedule respawn at outpost after 6s + kill++. Max drones: 4 active (5 if kills>8). Spawn initially 2 patrolling; escalate over time: every 25s up to cap. Drone hum sound: create on spawn: oscillator saw 90Hz + oscillator 140 detuned, through lowpass 400, gain 0; each frame gain target = clamp(1 - dist/90) * 0.12, pan = clamp(relX/40). Use StereoPannerNode. Also when engaging pitch rises: freq 100+speed*2. Bullets (drone): pool of 40 tracer objects: mesh (additive material, small thin box) or use Points? Mesh with scale; simpler: THREE.Sprite? Sprite always faces camera, tracer looks better as stretched box aligned to velocity: use Mesh(BoxGeometry(0.06,0.06,0.9), MeshBasicMaterial({color:0xff5533, transparent, blending additive})), set quaternion from velocity. Pool with inactive flag. Update: pos += vel*dt; life; if dist to player <0.9 → damage(9), kill tracer, red screen flash. If pos.y < terrainH+0.1 → dirt puff. Player shooting: fire rate 0.12s semi-auto? Full-auto hold. Raycast: direction from camera center + small spread. Test against each alive drone: sphere center body, r 1.5: ray-sphere intersect. Also core sphere r 2.6. Also terrain approximate: march ray up to 120m in steps of 3m, find ground hit → hit point for puff. Pick closest. Damage: drone 10 (3 shots), core 4 (15 shots → coreHP 60). Tracer visual: fading line from muzzle world pos to hit point: Line with additive material, store with ttl, update opacity. Pool a few. Recoil: camera pitch kick 0.012 + gun kickback z. Muzzle flash: sprite at muzzle toggled for 40ms + point light intensity decay. Sound gunshot: noise buffer burst with lowpass 1200 + click osc 180Hz decay; volume 0.5. Distance-based drone shot: "pew" square osc 880→220 0.12s, gain by distance. Explosion: noise with lowpass sweep 800→120, 0.8s, gain by distance. Hit marker: short 2kHz blip. Damage taken: 110Hz thump + noise. Bird ambient scheduled. Wind loop. Audio init on first user gesture (start button click). `AC = new (window.AudioContext||webkitAudioContext)()`. Beep on lock: when max drone lock > threshold and LOS, schedule: interval beep 1400Hz 0.03s; rate = lerp by lock. Implement as timer accumulation. Now HUD DOM: ```html

HEALTH bar, AMMO

THREAT, KILLS, FPS, SEED

… title, controls, DEPLOY button …

…

``` CSS: scanline overlay subtle, HUD monospace font with letter-spacing, amber glow text-shadow, health bar gradient green→red, damage flash red radial. Keep tasteful. Start screen design: big condensed title "CANOPY // PROTOCOL" hmm pick a name: "VERDANT SIEGE"? "JUNGLE PROTOCOL: OUTPOST ZERO". Title: "OUTPOST ∅ // EMERALD SECTOR". Let's do: main title "EMERALD PROTOCOL", sub "infinite jungle generator · drone interdiction AI". Controls list. Button "DEPLOY ▸". Background: live 3D slowly idle-rotating behind before lock (camera orbits spawn slowly). Nice: pre-lock attract mode camera slow orbit. Death overlay: "K.I.A. — THE CANOPY KEEPS ITS DEAD", stats, "REDEPLOY". Also ESC → pointer unlock → show pause overlay (reuse start with "RESUME"). Edge cases: pointer lock error (iframe restriction) — catch promise rejection, fallback: drag-look mode? To be robust, implement fallback mouse look without lock: if requestPointerLock fails, set `dragLook` mode where mousemove during pointerdown rotates. Simple to add: track pointerdown. Let's add it — safety for iframe. Mobile: ignore (desktop game) but don't crash. Performance monitor: fps ema; if <42 for 3s → pixelRatio 1, foliageScale=0.6 (affects future chunks), toast "ADAPTIVE QUALITY ENGAGED". Now write wind sway injection: ```js function addSway(mat, amp, freq, pivotFn){ mat.onBeforeCompile = (sh)=>{ sh.uniforms.uTime = uTime; sh.vertexShader = 'uniform float uTime;\n' + sh.vertexShader.replace('#include ', `#include #ifdef USE_INSTANCING vec3 iw = vec3(instanceMatrix[3][0], instanceMatrix[3][1], instanceMatrix[3][2]); float ph = iw.x*0.7 + iw.z*0.53; float sway = sin(uTime*${freq}+ph) + 0.5*sin(uTime*${freq*2.3}+ph*1.7); float w = ${pivotFn}; transformed.x += sway*${amp}*w; transformed.z += cos(uTime*${freq*0.8}+ph)*${amp*0.7}*w; #endif`); }; } ``` For leaves w = smoothstep(2,9,transformed.y); for grass = uv? Grass geometry: uv.y is 1 at top. `transformed` is local; use w = position.y (0 at bottom for our build). Build grass plane with base at y0. w = position.y/height. Pass as expression string, e.g., `(position.y*0.9)`. Vines: pivot top: w = (1.0 - uv.y) → wait, plane top uv.y=1? PlaneGeometry uv: top v=1. Vine hangs: we want top fixed, so geometry built with top at y=0 hanging down to -L; w = -position.y/L. OK. Template literal inside shader injection — be careful with number formatting (use fixed numbers). uTime shared: `const uTime={value:0}` updated each frame; materials referencing the same uniform object. Now sky ShaderMaterial: ```js vertex: varying vec3 vPos; void main(){ vPos = position; gl_Position = projectionMatrix*modelViewMatrix*vec4(position,1.); } frag: uniform vec3 sunDir; varying vec3 vPos; void main(){ vec3 d = normalize(vPos); float h = clamp(d.y,-0.15,1.); vec3 zen = vec3(0.44,0.62,0.66); vec3 hor = vec3(0.82,0.85,0.66); vec3 col = mix(hor, zen, pow(max(h,0.),0.55)); float s = max(dot(d, sunDir),0.); col += vec3(1.,0.86,0.55)*pow(s,340.)*1.2; // disc col += vec3(0.9,0.75,0.4)*pow(s,8.)*0.18; // haze // slight warm below horizon col = mix(col, hor*0.9, smoothstep(0.,-0.15,d.y)); gl_FragColor = vec4(col,1.); } ``` Fog color pick ~ rgb(0.78,0.82,0.62)*255 ≈ (199,209,158) = #c7d19e. FogExp2 density 0.012. Scene.fog. Sky material fog:false. Water color darker. Hemisphere light: sky #bcd6a8, ground #2e3a1f, intensity 0.9. Directional sun #ffe9b0 intensity 1.15, from sunDir. three r160 renderer lighting: default useLegacyLights false → physical mode; intensity OK. Tone mapping: renderer.toneMapping = ACESFilmic, exposure 1.05. outputColorSpace default SRGB. Canvas textures colorSpace SRGB. Camera: fov 74, near .1, far 400. Player eye height 1.7. Movement speed walk 6.2, sprint 9.4, accel smoothing via velocity lerp. Bob: camera y += sin(t*freq)*amp on ground & moving; footstep on bob cycle. Jump vy=7.5, g=20. Landing puff + sound. Head bob also sways gun. HUD updates throttled (every 100ms) except bars. Toast system: append div, animate via CSS (transform/opacity), remove after 4s. Center message for big events (OUTPOST DESTROYED etc) with letter-spacing animation. Compass: build strip: for each 15° generate a label: cardinal text or tick. Strip width 360*k, k=2.4px/deg. Duplicate content over -360..720. Implementation: function bearingLabel(b){ N/NE/E... } update: strip.style.transform = translateX(center - yawDeg*k). Outpost marker: separate absolute element positioned by bearing of outpost relative yaw similarly; hidden when behind? No—show on ribbon. Yaw convention: camera rotation Y; bearing = (-yawDeg) mod 360? In three, yaw 0 faces -Z (north). Define north = -Z. Bearing of direction vector: atan2(-dir.x?, ...). Let me compute: yaw = camera.rotation.y. Direction yaw around: forward = (−sin(yaw), 0, −cos(yaw)) in three (with rotation order YXZ). Compass heading = (−yawDeg?) Let's test: yaw=0 → forward (0,0,−1) = North → heading 0. yaw=+π/2 → forward (−1,0,0) = West → heading 270. So heading = (−yawDeg) mod 360. Bearing to target: bearing = atan2(dx, −dz)? For vector v to target: north is −Z: bearing = (atan2(v.x, −v.z) deg + 360)%360. Check v=(0,0,-1): atan2(0,1)=0 ✓; v=(−1,0,0): atan2(−1,0)=−90 → 270 ✓ West. Strip position for object bearing b: offset = wrapAngleDeg(b − heading) * k + center. OK. Now drone visuals: group: - body: SphereGeometry(0.55, 8, 6) scaled (1.3,0.6,1.3), material dark gunmetal MeshStandardMaterial? Lambert cheaper: MeshLambertMaterial({color:0x2a2e33}), slight emissive 0x0a0f12. - ring/eye: small sphere at front, MeshBasicMaterial red 0xff2222 + glow sprite additive. - 4 arms: BoxGeometry(1.7,0.07,0.12) rotated 45° each pair? 2 crossed boxes rotated 45° each. - rotors: 4 cylinders (r 0.55, h 0.02) at arm ends, rotation.y += 40*dt; material dark with opacity 0.55 (motion-blur illusion) + hub. - gun: small box + barrel cylinder pointing forward-bottom. - glow sprite additive scale 1.6 pulses. Drone orientation: lookAt(aimPoint) smoothly; bank via roll by lateral velocity. Death anim: disable, tilt, fall, spawn sparks each frame, explode on ground contact. Respawn: outpost spawns with flash + toast "DRONE LAUNCHED". Outpost model: - platform legs: 4 boxes - tower: CylinderGeometry(3.2, 4.2, 10, 8) - core: Sphere r 2.0 emissive red pulse, atop? front. Core placed at height 8. - dish: rotating cone/disk. - beacon PointLight red small radius 30, pulsing — one dynamic light OK. - fence? Skip. - clear trees in 26 radius (already handled by chunk build check). - Also add a warning: when player within 90m first time: toast "ELM GRID ONLINE — YOU ARE BEING TRACKED", spawn extra drone. Core damage: sparks + shield flash (core material emissiveIntensity spike). HP bar shows in right panel when <100%: "CORE ▓▓▓". Win: explosion particles big, light flash, drones die in chain, message "OUTPOST NEUTRALIZED — THE JUNGLE RECLAIMS", birdsong louder (ambient gain up), threat indicator → green "CLEAR". Persist: none. Bullet vs player: player pos is eye position; body center = pos−(0,0.8,0); check dist<0.85. Damage: hp -= 8+rng*5; lastHit=t; if hp<=0 → die(): unlock? Keep lock, show death overlay, stop movement, drone stop firing (state patrol). Respawn: reset hp, position spawn, toast. Regen: if t-lastHit>6: hp += 6*dt up to 100. Now sound code sketch: ```js const AU = { ctx:null, master:null, started:false, init(){ if(this.started) return; this.ctx = new (AudioContext)(); master gain 0.8 → ctx.destination; noiseBuf = create 2s white noise buffer; wind: bufferSource loop noise → biquad lowpass 320 + gain 0.05 (LFO on filter freq for gusts); birdTimer; }, noise(dur){ source from buffer }, shot(vol){ noise burst hp/bp + osc thump }, ... } ``` Bird chirp: osc sine freq start 2400*rnd+1800, exponential down, gain envelope 0.06→0; 2-4 chirps repeated with 0.12s interval. Schedule with setTimeout chain in update loop (accumulate timer with Math.random). Howler monkey: every 20-40s: osc 160→90 saw with lowpass, 1.2s, quiet 0.05, slight vibrato. Nice jungle feel. Wind LFO: osc 0.07Hz → gainNode.gain via GainNode chain; simpler: set filter.frequency.setTargetAtTime randomly every 2s in update. Or lfo osc → lfoGain(gain=150) → filter.frequency (base 300). OK. Drone hum manager: each drone has {osc1, osc2, filt, gain, pan} create on spawn (if AU started; else create on audio start for existing drones — handle: only spawn sound when audio started; also on audio init, attach to existing drones). updateAudio each frame: for each drone: d = dist; g = clamp01(1 - d/110); g = g*g*0.16 (engaged *1.3); pan = clamp(relX/50, -1, 1) where relX = dot(dronePos-camPos, camRight). Set gain smooth (setTargetAtTime). freq base 85 + speed*1.5 + engage*20. Explosion(vol by distance), hit marker, etc. Footsteps: on bob cycle cross: filtered noise tap 0.06, gain 0.05, freq by surface (always dirt). Now particle pool: ```js const PMAX=600; positions Float32, colors, sizes? PointsMaterial size fixed 0.35 with map glow, vertexColors, transparent, depthWrite false, blending additive? Mix: use additive for sparks — dirt puff additive is weird but acceptable; use NormalBlending with grey-brown color for dirt. Choose additive overall, use darker orange for smoke? Use additive and darker colors; fine. ``` Data arrays: pos, vel, life, maxLife, col. spawnBurst(x,y,z,n,speed,spread,color...). Update: gravity per particle optional (store g in separate array). Keep simple: all affected by -3*dt? Sparks OK. Falling leaves: separate Points 140, positions recycled within 40m box around player; drift with wind sin + slow fall; color green/yellow; PointsMaterial size 0.18 map leafSmall (small square alpha), normal blending. Rotate? Points can't rotate; fine. Pollen: 160 points, additive, size 0.07, drift slow, sparkle via sin on material? Keep static opacity; OK. Now code size is large but let's write tight. Watch syntax errors; lint mentally as we go. Importmap with three 0.160.0 module. jsdelivr might be more reliable: https://cdn.jsdelivr.net/npm/three@0.160.0/build/three.module.js. Use jsdelivr. Also include Google fonts link. Let me write the final HTML. Structure: ```html EMERALD PROTOCOL — Infinite Jungle

canvas appended to body by three HUD... overlays...

``` CSS: body margin 0 overflow hidden background #0a0f0a; canvas block. HUD font stack. Let me define CSS classes: - .mono { font-family:'IBM Plex Mono',monospace } - #hud pointer-events none; children as needed. - crosshair: dot at center + gap lines, with 'hit' flash class for hitmarker X. - #vignette: radial gradient transparent → rgba(5,10,5,.55) always (jungle claustrophobia). - #dmgflash: red radial, opacity controlled by JS. - low hp pulse via class on vignette. - panels: background rgba(8,14,8,.55), border 1px solid rgba(190,255,170,.25), backdrop-filter none, slight skew? Use clip-path corner cuts for tactical feel: `clip-path: polygon(0 0, calc(100% - 12px) 0, 100% 12px, 100% 100%, 12px 100%, 0 calc(100% - 12px))`. Nice. - amber #ffcf6e, green #9dff8a, red #ff5340. Start overlay: full screen, background radial dark green + repeating-linear-gradient scanlines; title font 'Big Shoulders Display' 900 huge letter-spacing; sub row; controls grid; DEPLOY button with hover animation (translate + glow). Plus small footer: SEED value, version. Death overlay similar red theme. Toast: right column, each with border-left amber, slide-in animation. Center message: big condensed, animate scale/fade. OK let's code JS. Let me write it out fully and carefully. ```js import * as THREE from 'three'; /* ============================== CORE / UTILS */ const clamp=(v,a,b)=>vb?b:v; const lerp=(a,b,t)=>a+(b-a)*t; const rand=(a=1,b)=>b===undefined?Math.random()*a:a+Math.random()*(b-a); const SEED=(Math.random()*2147483647)|0; const TAU=Math.PI*2; function mulberry32(a){return function(){a|=0;a=a+0x6D2B79F5|0;let t=Math.imul(a^a>>>15,1|a);t=t+Math.imul(t^t>>>7,61|t)^t;return((t^t>>>14)>>>0)/4294967296;}} function h2(x,y){let n=Math.imul(x|0,374761393)^Math.imul(y|0,668265263)^SEED;n=Math.imul(n^n>>>13,1274126177);n^=n>>>16;return(n>>>0)/4294967296;} function vnoise(x,y){const xi=Math.floor(x),yi=Math.floor(y),xf=x-xi,yf=y-yi;const u=xf*xf*(3-2*xf),v=yf*yf*(3-2*yf);const a=h2(xi,yi),b=h2(xi+1,yi),c=h2(xi,yi+1),d=h2(xi+1,yi+1);return a+(b-a)*u+(c-a)*v+(a-b-c+d)*u*v;} function fbm(x,y,o=4){let s=0,amp=.5,f=1;for(let i=0;i{ g.fillStyle='#5a4632';g.fillRect(0,0,s,s); for(let i=0;i<260;i++){const x=rand(s),w=rand(1,3.5); g.strokeStyle=`rgba(${30+rand(50)|0},${22+rand(34)|0},${14+rand(20)|0},${rand(.25,.7)})`; g.lineWidth=w;g.beginPath();const y0=rand(s);g.moveTo(x,y0);g.bezierCurveTo(x+rand(-6,6),y0+s*0.3,x+rand(-6,6),y0+s*0.6,x+rand(-4,4),y0+s);g.stroke();} }); barkTex.repeat.set(2,3); ``` Wait, stroke that goes beyond canvas vertical is fine (no need to wrap seam vertically). Horizontal seam may show; acceptable with noise. Add speckles. Moss ground: ```js const mossTex=canvasTex(256,(g,s)=>{ g.fillStyle='#42571f'? hmm base; then thousands of dots various green/brown; }); ``` Implementation: fill '#3f5426'; 4000 small rects with random colors from palette [#37511f,#4a6427,#57752f,#2e441a,#6b5a36,#546b2c]; occasional leaf-litter specks #7a6a3a. Leaf texture (for canopy? Canopy blobs don't need texture; use flat color + slight noise? Give canopy a noisy leaf texture for richness: canvas with mottled greens; map on icosa uv is chaotic but fine.) canopyTex: 128, base '#3e6b2a', darker/lighter blobs + few holes? No holes (blobs are solid). Grass tuft texture (alpha): 128: draw ~9 leaves: quadratic curves from (s/2 + spread, s) to tips with strokeStyle of green gradient, lineWidth tapered—can't taper stroke; use filled triangles instead: ```js for(i..9){const bx=s*0.5+rand(-30,30), tipx=bx+rand(-26,26), tipy=s*rand(0.08,0.35); g.fillStyle=`rgba(${g1},...` choose color; path moveTo(bx-3,s), quadraticCurveTo(bx+.., ...) build curved blade with two curves to tip; fill. } ``` Simplify: leaves as thin triangles slightly bent (two quadratic curves). Colors varied. Fern texture similar but leaves radiating from bottom center (palm-like): each leaf is a stem line + small leaflets stroke: heavy but OK: draw 7 leaves at angles -70..70 degrees from vertical; each leaf: stroke main stem, then 12 short side strokes. Color #2f6b30 variations. Vine texture: 64x256: vertical stem line + pairs of small leaves along alternating; background transparent. Glow sprite texture: radial gradient white → transparent 64. Leaf point texture: 32 small blurred square. Now materials: ```js const barkMat=new THREE.MeshLambertMaterial({map:barkTex,color:0xffffff}); const canopyMat=new THREE.MeshLambertMaterial({map:canopyTex,color:0xffffff}); addSway(canopyMat,...) const grassMat=new THREE.MeshLambertMaterial({map:grassTex,alphaTest:0.45,side:THREE.DoubleSide}); addSway(grassMat, small, w=position.y) const fernMat similar const vineMat: map vineTex alphaTest .4 doubleSide; sway pivot top const rockMat: Lambert 0x77816d flat ``` instanceColor: set mesh.instanceColor via setColorAt — need material with `vertexColors:false` — works with Lambert (defines USE_INSTANCING_COLOR). Yes. Geometry builders: mergeGeos(geos): all non-indexed: ```js function mergeGeos(list){ let pos=[],nor=[],uv=[],col=[]; for(const g of list){const n=g.index?g.toNonIndexed():g; pos.push(...n.attributes.position.array); nor.push(...n.attributes.normal.array); uv.push(...(n.attributes.uv? n.attributes.uv.array : new Float32Array(n.attributes.position.count*2))); if(n.attributes.color) col.push(...n.attributes.color.array); } const geo=new THREE.BufferGeometry(); geo.setAttribute('position',new THREE.Float32BufferAttribute(pos,3)); geo.setAttribute('normal',new THREE.Float32BufferAttribute(nor,3)); geo.setAttribute('uv',new THREE.Float32BufferAttribute(uv,2)); if(col.length) geo.setAttribute('color',new THREE.Float32BufferAttribute(col,3)); return geo; } ``` Spreading huge arrays — for small templates fine. Tree template function: ```js function treeTemplate(seedR){ const H=8.5+seedR()*3.5, rB=0.5+seedR()*0.22; const trunk=new THREE.CylinderGeometry(rB*0.32,rB,H,7,3); trunk.translate(0,H/2,0); const parts=[trunk]; // slight flare roots: add cone at base const flare=new THREE.CylinderGeometry(rB,rB*1.9,0.9,7);flare.translate(0,0.45,0);parts.push(flare); const branches=[]; const nb=4+((seedR()*3)|0); for(let i=0;i{...}); return {trunkGeo, canopyGeo, H}; } ``` addVertexColor(geo, fn): iterate positions, compute color, set attribute. Canopy color: base = mix(darkGreen, lightGreen, noise-like from position hash) * (0.55+0.45*clamp(normalY? use position relative). Simpler: factor = clamp((y - H*0.6)/ (H*0.6), 0,1)*0.5+0.5; also underside darker via normal.y? Need normal access: read normal attribute. ```js function paintCanopy(geo,H){ const p=geo.attributes.position, n=geo.attributes.normal; const arr=new Float32Array(p.count*3); const cA=new THREE.Color(0x274d1c), cB=new THREE.Color(0x7fae3f), tmp=new THREE.Color(); for(let i=0;i{const q=new THREE.PlaneGeometry(1,1);q.translate(0,0.5,0); const q2=q.clone().rotateY(Math.PI/2); return mergeGeos([q,q2]);})(); ``` UV fine. Set sway w = position.y. Fern: plane 1x1 translate .5, two crossed, scale by instance. Vine geometry: ```js const vineGeo=(()=>{const g=new THREE.PlaneGeometry(0.5,6,1,8); const p=g.attributes.position; for(let i=0;i.. wet dark near water: if y{ q.setFromAxisAngle(Y,it.r); m4.compose(it.p,q,it.s); im.setMatrixAt(i,m4); if(colFn) im.setColorAt(i,colFn(it,i)); }); im.instanceMatrix.needsUpdate=true; if(im.instanceColor) im.instanceColor.needsUpdate=true; im.frustumCulled=true; // compute bounding sphere: three computes from geometry only! InstancedMesh culling uses geometry bounds → wrong. Set im.frustumCulled=false OR set boundingSphere manually. Simplest: im.frustumCulled=false (chunk group culled? group culling is per-object). Alternative: compute bounding sphere covering chunk: im.geometry.boundingSphere manually... but shared geometry! Instead set im.frustumCulled=false. Rely on fog distance. OK. return im; } ``` Since geometry is shared across chunks, can't set bounding sphere per mesh. Use frustumCulled=false for instanced sets. 25 draw types * 25 chunks fine. Store in chunks map: {group, ims:[...], geo}. dispose: scene.remove(group); geo.dispose(); each im.dispose() (InstancedMesh.dispose disposes instance attributes; exists in r160 — yes, added long ago? InstancedMesh.dispose was added around r150s; safe: if(im.dispose) im.dispose()). updateChunks(px,pz): ```js const ccx=Math.floor(px/CHUNK), ccz=...; needed set within VIEW; add missing (budget 2/frame, sorted by distance), remove out of range (+VIEW+1 hysteresis to dispose? just remove outside VIEW). ``` Chunk world bounds for placement need ox etc. OK. Note: trees near chunk edges may pop visually at boundaries but instancing covers full chunk; neighbor trees may cross boundary — fine. Player physics: ```js const player={pos:new THREE.Vector3(0,terrainH(0,0)+1.7,0),vel:new THREE.Vector3(),yaw:Math.PI,pitch:0,onGround:true,hp:100,ammo:30,reloading:0,lastHit:-9,kills:0,bobT:0,stepT:0}; ``` yaw initial: face toward outpost? Nice: face the outpost: yaw = atan2? Forward (−sin,−cos): we want forward ≈ direction to outpost: dir=(OP.x,OP.z). Solve −sin(yaw)=dx, −cos(yaw)=dz → yaw=atan2(−dx,−dz). Set that so first sight lines toward threat. Input keys set. Mousemove: when locked or dragging: yaw -= mx*sens; pitch clamp ±1.45. Update movement: ```js const f=new THREE.Vector3(-Math.sin(yaw),0,-Math.cos(yaw)), r=( -f.z? right = (Math.cos? ) right = new V3(-f.z? ... right = cross(f, up)? forward × up = right? f × up = (f.z*1? ) Let me just compute: right = new Vector3(f.z? ) Actually right vector = (cos(yaw)?,0,-sin?) Let me derive: with yaw rotation, right = (Math.cos(yaw)? ...). In three, direction: forward=(-sinY,0,-cosY); right=( cos? ) rotate forward -90° around Y: right=(f.z*? ) rotation -90: (x,z)→( -z? ). Rotate vector (x,z) by -90° around Y: (x,z) → (−z, x)? For yaw=0: f=(0,−1) in xz; right should be (1,0)? hmm xz-plane: right = (1,0,0)?

Core HP 60. coreHit(): hp-=4; flash; sparks; if<=0: destroyOutpost(): big explosion, shockwave toast, kill drones (set dead), beacon off, ambient brighter, centerMsg. Player damage function: hp; dmgFlash opacity 0.85 decay; camera shake 0.35; AU.hurt(); if hp<=0: die(): dead=true; show overlay with stats; unlock? release pointer lock; stop movement. Respawn: reset hp, position spawn, toast. Respawn resets pos to spawn, hp 100, ammo; drones keep. Regen: if t-lastHit>6: hp += 6*dt up to 100. Now audio code more concretely: ```js const AU={ctx:null,on:false, init(){if(this.on)return;const C=this.ctx=new (window.AudioContext||window.webkitAudioContext)(); this.master=C.createGain();this.master.gain.value=0.7;this.master.connect(C.destination); // noise buffer const b=C.createBuffer(1,C.sampleRate*2,C.sampleRate);const d=b.getChannelData(0);for(let i=0;i120)return; v=0.25*(1-dist/120)+0.02; osc square 950→180 0.12s; } droneAdd(d){ if(!this.on)return; const C=this.ctx; o1 saw 82, o2 saw 123 slightly detune set later; filt lowpass 500; g gain 0; pan StereoPanner; o1,o2→filt→g→pan→master; start; d.snd={o1,o2,g,pan,filt}; } droneRm(d){ stop osc, disconnect } droneTick(dist,lock) handled in update: set gain target: d.snd.g.gain.setTargetAtTime(v,C.currentTime,0.1) hit(){ blip 1900hz 0.05 } hurt(){ osc 100 sine gain .5 decay .25 + noise low } explosion(v){ noise lowpass 700→90 0.9s gain v } reload(){ two clicks scheduled } step(){ noise bp 300 gain .05 .05s } beep(lock){ osc 1350 square 0.04 gain 0.04+lock*0.03 } ``` Wrap all with `if(!this.on)return`. Ambient scheduler in main loop: birdT-=dt; if<0 { AU.bird(); birdT=rand(1.5,6);} howlerT similar 18-40. Threat beep: compute maxLock among engaging drones with LOS; if>0.25: beepT-=dt*(0.5+maxLock*3); if<=0 {AU.beep(); beepT=0.5? } Actually rate: beepT countdown with scale. Update HUD each frame cheap: health bar width via style, ammo text, threat class. Throttle text updates via 100ms accumulator to avoid layout thrashing. Compass DOM: strip built once: ticks every 15° from 0..359 duplicated ×3 with offset -360,0,360. Each tick div absolute left = (b+360)*k. Label N/NE etc. k=2.2px/deg; strip inside container width 260px center. Update: heading=(-yawDeg mod 360); xoff = 130 + 360*k − heading*k; strip.style.transform=`translateX(${xoff}px)`; wait compute: tick for bearing b is positioned at left=(b+360)*k (strip covers -360..720 → index (b+360)). Screen x = left + tx. We want bearing==heading at center (130): tx = 130 − (heading+360)*k. Since strip covers range, bearings heading±59 visible. OK. Outpost marker: bearing b_op → left=(b_op+360)*k + also duplicate? Place 3 markers at b, b±360; simpler create 3. Also threat arrow around crosshair when off-screen drone engaging? Skip — compass marker enough (red). Center messages function msg(text, sub). Toasts: function toast(text, cls). Start flow: DEPLOY button → AU.init(); resume ctx; canvas.requestPointerLock({unadjustedMovement:true})? Just requestPointerLock(); catch error → fallback drag mode toast "POINTER-LOCK UNAVAILABLE — DRAG TO LOOK". Hide overlay. On pointerlockchange: if not locked && playing && not dead → show pause overlay (reuse start with RESUME text). Implement `showStart(mode)`. Attract mode before first deploy: camera slowly orbits spawn: if(!started){camera pos = orbit; lookAt center; skip player physics; render} Death overlay button REDEPLOY → hide, respawn, re-lock. Also handle resize. FPS meter: ema; show in right panel; adaptive downshift. Add small "shader" mention too? we have sky shader, sway shader injection — good. Edge: `InstancedMesh.setColorAt` before first render OK; must mark instanceColor needsUpdate (setColorAt creates the attribute). Fine. InstancedMesh count = list length; if zero skip creation. Another consideration: mergeGeos with templates: PlaneGeometry is indexed → toNonIndexed OK. CylinderGeometry indexed too. Icosahedron non-indexed already? IcosahedronGeometry is indexed? PolyhedronGeometry is non-indexed (built from positions without index). Handle: if(g.index) toNonIndexed else use. Canopy material with vertexColors true + instanceColor: combined? instanceColor multiplies material color and vertex color? In shader, both vColor from instancing and vertex color multiply when defined: both contribute to vColor. Yes, three combines (color_vertex chunk handles both). Good: instanceColor slight tint variation. Canopy Lambert + map + vertexColor: color = map * vColor * diffuse. Sway for canopy: modify after begin_vertex; instancing transform applied later (project_vertex uses instanceMatrix in begin? Actual order: begin_vertex sets transformed=position; then skinning etc; project_vertex applies instanceMatrix & modelViewMatrix. So transformed is local → sway in local space is fine; phase from instanceMatrix[3]. Good. For grass w use local `position.y` (0..1). Amp 0.08, freq 2.2. Vines: pivot top at local y=0 hanging to -6: w=clamp(-position.y/6.,0.,1.); amp 0.35 (hanging sway more), freq 1.1. Canopy: w=smoothstep(3.,9.,position.y), amp .18, freq 1.3. Trunk also slight sway? Skip (barely visible). GLSL string injection numbers: ensure template literal produces valid floats — since we hardcode the numbers in strings per material call, write addSway(mat, {amp:'0.18', freq:'1.3', w:'smoothstep(3.0,9.0,position.y)'}). Write: ```js function addSway(mat,amp,freq,wExpr){ mat.onBeforeCompile=sh=>{sh.uniforms.uTime=uTime; sh.vertexShader='uniform float uTime;\n'+sh.vertexShader.replace('#include ', `#include #ifdef USE_INSTANCING float swPh=instanceMatrix[3][0]*0.63+instanceMatrix[3][2]*0.41; float swW=${wExpr}; transformed.x+=(sin(uTime*${freq}+swPh)+0.6*sin(uTime*${freq*2.7}+swPh*1.31))*${amp}*swW; transformed.z+=cos(uTime*${freq*0.83}+swPh)*${amp}*0.8*swW; #endif`);} } ``` freq*2.7 JS number e.g. 3.5100000000000002? Compute with clean literals: pass two frequencies: addSway(mat, amp, f1, f2, wExpr) with literal strings. Use toFixed(2) to keep GLSL safe. Simplify: precompute strings via `const F1=freq.toFixed(3)` etc. Water follow: water.position.x=camera.x etc — but plane is 420 wide, chunk area same; OK. Pollen/leaves points follow player: recenter when far: implement each particle relative position with wrap-around modulo box around player: store absolute positions; in update if |p-cam|>25 wrap by 50. Simple. Explosions: spawnBurst(pos, 40, orange) + flash sprite + AU.explosion(vol by dist) + camera shake by proximity. Screen shake: shake amount decays; camera.rotation.z += small? Apply offset to camera pos with random * shake, and roll. Muzzle flash light: PointLight(0xffc873, 0, 18) attached to camera; on fire intensity 20 → decay *=exp(-30dt). Drone glow sprite: SpriteMaterial additive red; pulse scale 1.2+sin. Also add drone scan beam when patrol? Creepy red spotlight cone under drone (additive cone mesh, faint) — cheap fake: Mesh cone additive opacity .07 always on; looks like sensor. OK add. Outpost build details: ```js const opG=new THREE.Group(); opG.position.copy(OUTPOST); base pad: CylinderGeometry(9,10,1.2,10) dark concrete y .6 — but terrain slope; OK. tower: Cylinder(2.8,3.6,11,8) y ~ 6.6 material dark metal lambert 0x30363b struts 4 boxes angled top deck cylinder wider 4.4 h1 core: sphere r1.9 at y 10.6? placed mid: core y 8.2 with ring torus dish: on side, rotates: group with dish = CircleGeometry? Cone(2.4,1.2, 12, 1, true) open rotated; spin slowly; antenna thin cyl + blinking light sprite beaconLight=PointLight(0xff3020, 0, 40) at core; pulse when alive. fence? skip. add red glow sprite at core. ``` coreWorldPos = OUTPOST + (0,8.2,0). Save globally CORE_POS. Hits: ray-sphere r 2.4. Core flash: coreMat emissiveIntensity spike. Also drones spawn from outpost: spawn pos = CORE_POS + up 3 + random offset, with launch sound (rising tone). Center message on outpost destroy + threat cleared. Post-destroy: drones remaining: each → dead fall. nextDrone stop. beacon off, core blackened. Now think about bullet vs player fairness: drone bullet speed 90 m/s, at 20m lead small; dispersion early gives chance. Player can sprint & strafe. OK. Also drone avoidance of outpost? Not needed. Drone-drone collision: skip. Toast when first drone engages: "ELM UNIT LOCKED ON — EVADE". HUD right panel: THREAT: SAFE/SEARCH/LOCKED (color), KILLS, CORE %, FPS, SEED id. Left panel: HP bar + number, AMMO big number + reload indicator, weapon name "VK-78 'MACHETE'". Controls text at bottom-left small. OK — also ensure syntax robustness: avoid fancy unicode in JS strings where risky (mostly fine). Use ASCII mostly. Potential pitfalls: three r160 Lambert + fog + vertexColors OK. PlaneGeometry uv multiply for ground: after rotateX, uv attribute exists; iterate. Ground color paint needs world coords: compute during vertex loop before computeVertexNormals? colors independent of normals; but want slope shading → compute normals first then color loop. Keep stored local wx, wz array from displacement loop in a Float32Array. Ground chunk geo dispose on removal. Chunk groups: add all IMs + ground mesh to group; scene.add(group). Removal: scene.remove(group); geo dispose; im.dispose each. Budget builds: sort needed by distance, build up to 2 per frame. Initial: prebuild all chunks synchronously before first frame? 25 chunks * ~(ground 784 vertices + ~600 instances) — fast (~50ms?). Fine to prebuild on start to avoid pop at spawn: call updateChunks with large budget 99 once. Tree instance count per chunk: dens up to 20; total trees ≤ 500; canopy tris each ~(6 blobs * 80 tris*? icosa detail1 = 80 faces) *6 = 480 + trunk ~ 100 → 580 * 500 = 290k tris. Plus grass 25*220*4 tris=22k. OK. Icosahedron detail 1 = 80 tris yes. Drone tris small. Total fine. Pixel budget OK. Now "ELM brain" — explicitly name module in code & HUD: when drone locks, toast "ELM-9 COMBAT CORTEX LOCKED". Right panel threat display "ELM LINK". Also outpost label "ELM GRID". Good flavor. Let me write HUD DOM/CSS carefully then JS. Also include a noscript fallback? Skip. Title: "EMERALD PROTOCOL". Subtitle: "infinite jungle // ELM drone interdiction". Fonts: Big Shoulders Display (weight 500;700;900? Google fonts v2 css: family=Big+Shoulders+Display:wght@500;700;900) + IBM Plex Mono 400;600. Let me write CSS with strong typographic contrast: huge condensed titles, small monospace labels with letter-spacing. Scanlines: repeating-linear-gradient overlay on overlays only (subtle), not main HUD (perf/legibility). Damage vignette: inset shadow red via radial-gradient element, opacity via JS. Low HP: body class 'lowhp' → vignette pulse animation. Crosshair: center dot + 4 lines with gaps; hitmarker flash class. OK, code for HUD update: ```js hud.hp.style.width = hp+'%'; color shift via class threshold. hud.ammo textContent hud.threat text & class hud.core text fps compass transform op marker transform ``` Threat calc: max lock among engage drones with LOS: 0 safe (green 'LOCAL FAUNA ONLY'), <0.4 'SEARCHING', else 'ELM LOCK'. Also off-screen enemy direction: skip. OK now to write it all out. Remember: don't mention iframe; include everything in one code block; full HTML. Also verify: `renderer.domElement` style position fixed top 0. Pointer lock change handler: document.addEventListener('pointerlockchange', ...) if lock null & started & !dead → pause overlay. Mouse move: if(document.pointerLockElement===canvas) use movementX; else if dragging (pointerdown) use last pos delta. Shoot input: mousedown left → firing=true until mouseup; only when started && !dead && locked (or dragging? still allow fire on click in fallback). Reload on R. Also prevent context menu. Ensure click on DEPLOY doesn't fire weapon: started set after click; firing only when started. Autofire loop in update: if(firing && t>=nextFire) tryFire. nextFire initial 0. Ammo pickup? Infinite reserve; reload R or auto. Gun model detail: ```js gun group: receiver: Box(0.09,0.13,0.5) dark 0x23282b barrel: Cyl r0.025 length 0.42 rotated X? align to -Z: cylinder default Y; rotateX(PI/2). Position z -0.45 handguard box 0.07,0.09,0.28 0x3a4034 olive mag: Box(0.06,0.18,0.1) tilted stock back box sight post small muzzle tip at (0, 0.02?, -0.68) local; save muzzleLocal. ``` Gun animation: base position (0.3,-0.32,-0.62); sway: gun.position.x = base + (-mouseDXsmooth*0.02) etc; bob; recoil z += kick. Muzzle flash: sprite scale 0.5 additive texture, at muzzle local, visible for few frames. Muzzle world position for tracer: gun.localToWorld(muzzleLocal.clone()) — need gun.updateMatrixWorld first; use camera.updateWorldMatrix then localToWorld. Tracer line: BufferGeometry setFromPoints [a,b]; material LineBasicMaterial({color:0xffd9a0,transparent,opacity}) pooled 12; ttl .12. Drone hit spark: burst particles at hit point + AU.hit + hitmarker class. Also shoot ground/leaf puff: brown-green burst small. Camera shake variable shake=0; add on damage/explosion near; apply camera.rotation.z=(rand-0.5)*shake*0.05 & pos jitter. Recoil: pitchKick spring: player.pitch += recoilV*dt; recoilV decay; simpler: on shot add pitchOff += 0.014, pitchOff *=exp(-12dt) and applied additively. OK now let's actually write the final file. Careful with brackets. I'll compose it in one go, being meticulous. Also remember: dt clamp 0.05. Main loop with renderer.setAnimationLoop(loop). uTime update = t. Chunk update every 0.2s via accumulator. Also initial camera before start: orbit spawn radius 14 height terrain+6 lookAt spawn. After start: snap camera to player. Handle player falling into deep water: ground below water; walk slow; fine. Edge: terrainH is used for drone ground avoid, bullets, LOS — all cheap functions called maybe hundreds of times per frame? LOS 8 samples * 5 drones = fine. Bullet terrain check 48*1. Fine. Sound: pan via StereoPanner compute camRight dot. Also geiger beep only when engaged lock present. Final checks for drone update budget: 5 drones trivial. OK write. Also small: `THREE.MathUtils` not needed. Also HUD initial "SEED" display: SEED.toString(16). Write toast function with max 4. Let me draft the final answer. It's going to be long — that's fine. Ensure single code block, full HTML, no mention of iframe. Also double-check sway shader chunk name for r160: `#include ` exists in lambert vertex. Yes. Instancing define: USE_INSTANCING is automatically defined when rendering InstancedMesh. instanceMatrix attribute accessible in vertex shader. Reading instanceMatrix[3][0] is valid GLSL (mat4 column access) — mat4[i] is vec4 column; column 3 = translation. ✓ Sky sphere follows camera & frustumCulled false. Water: transparent; renderOrder default OK. Fog + additive sprites: fog affects Sprite? SpriteMaterial fog default true; set fog:false for glow. Particles PointsMaterial fog true OK. Verify `new THREE.PlaneGeometry(1,1)` uv: (0,1) top-left etc. translate so bottom edge at y0 for grass geometry ✓ sway uses position.y ✓. alphaTest with Lambert: works. Drone lookAt: mesh.lookAt aims -Z? Object3D.lookAt orients +Z? For camera it's -Z; for normal object lookAt orients +Z axis toward target? Actually Object3D.lookAt uses matrix lookAt which orients -Z? THREE: object's positive Z axis faces the target? Docs: "Rotates the object to face a point in world space" — uses lookAt matrix like camera which looks down -Z, but for non-camera objects the up is... actually for non-camera objects, lookAt orients -Z? Let me recall: Object3D.lookAt: if it's a camera or light, m.lookAt(position, target, up) else m.lookAt(target, position, up). For normal objects the target comes first → +Z faces target? Matrix4.lookAt(eye,target,up) builds Z = eye-target normalized (z axis points from target toward eye), so object's -Z points toward target... For non-camera: m.lookAt(target, position, up) → z = target - position → +Z toward? With arguments swapped, z axis = normalize(targetPos - objPos)? Matrix4.lookAt(eye, target, up): _z.subVectors(eye, target). If eye=target param..., for non-camera: m.lookAt(targetPoint, objectPos, up) → z = targetPoint - objectPos → object's +Z axis points from object toward target? _z = eye - target = targetPoint - objPos → so +Z axis points from object toward targetPoint. So mesh.lookAt(point) aims +Z toward point. So build drone facing +Z (eye/gun on +Z side). Then muzzle offset +Z. Use quaternion slerp: keep target quaternion: tmpObj? Use m4.lookAt(pos, aim, up) then quaternion.setFromRotationMatrix — but that is camera-style (-Z). Easier: create dummy Object3D each frame? For 5 drones OK: dummy.position.copy(drone.pos); dummy.lookAt(aimPoint) → gives +Z orientation; then slerp drone.mesh.quaternion toward dummy.quaternion. Then bank: multiply small z rotation: mesh.rotateZ(bank) after slerp? Apply bank as additional quaternion multiplication in local space: mesh.quaternion.multiply(qRoll). Compute roll = clamp(lateralVel*0.04, ±0.5). lateral = vel dot mesh right (col 0 of matrix). OK. Drone gun direction for bullet: use the aim ideal dir we computed, not mesh orientation (consistency with ELM). Fine. Rotor rotation: save array; each rotation.y += 50*dt. Drone scan cone: ConeGeometry(3.5, 9, 12, 1, true) position y -5 (below), material additive red opacity 0.06, depthWrite false. Rotate so apex is at drone: cone default apex is +Y up with height center; translate -height/2 so apex at origin? Cone apex at +h/2. We want apex at drone pointing down: rotateX(PI) then translate y -h/2. Wrap in group. Only visible when patrol/engage (always) & outpost alive. Drone death fall: also emit smoke. Now particle update: array: ```js const PMAX=700, pGeo with position & color; arrays pVel Float32Array(PMAX*3), pLife, pMax, pGrav. points frustumCulled false. spawnBurst(x,y,z,{n,spd,up,col,size?}): find dead slot (index pointer scan with wrap). update loop all PMAX: if life>0: integrate; life-=dt; color fade by writing color attr * (life/max)? Cheaper: shrink? PointsMaterial single size; fade by scaling color toward 0 (additive → fades). Write color each frame for alive only. needsUpdate on attrs. ``` PointsMaterial({size:0.32,map:glowTex,transparent,depthWrite:false,blending:Additive,vertexColors:true}). Leaves & pollen separate Points, simple drift; leaves normal blending colored; pollen additive faint. Leaves update: each: pos += (wind x + sin drift, fall -0.5.., z drift); wrap around player box 44. Implement leaves as array of data in Float32 pos attribute with velocities implicit via index hash. Pollen: slow sin float around fixed offsets from player: pos = base + sin(t*spd+phase)*amp, base wrapped around player. OK. Ambient occlusion feel: darken ground vertex color near many trees? Skip. Time to write final. Also small FPS meter: frames counter per second. Adaptive: if fps<40 && pixelRatio>1 → set 1, toast. Also `renderer.info.render.calls` show in right panel "DRAW". Now compose HTML. Also ensure `#app` not needed; canvas appended to body; HUD divs after. Also add `user-select:none` and canvas cursor crosshair when no lock fallback. Also handle prevent Space default (scrolling) - overflow hidden anyway; still preventDefault on keys for Space/arrows. Now let me write out the whole JS in final form. Careful with all variables defined before use in module top-level order (function hoisting OK). Order: 1. utils/rng/noise/terrain 2. constants outpost 3. renderer/scene/camera/lights/sky/water 4. textures 5. sway + materials + templates + geometry helpers 6. particles/leaves/pollen 7. chunks system + initial build 8. audio AU 9. player + input + gun 10. bullets 11. drones + spawn 12. outpost build 13. HUD refs & functions 14. game state machine (start/pause/death), overlays 15. main loop Note: AU.droneAdd references drones array — define drones before spawn; audio init later anyway. buildDroneMesh returns {group, rotors:[], glow, cone}. Write damagePlayer(n, fromDir). Also don't forget: while player dead, drones don't fire: check player.dead in fire condition; also LOS uses player alive. Respawn also resets nextDroneT? No. Ammo reload function: reloading=1.15; after done ammo=30; sound. tryFire handles empty click sound. HUD ammo shows "RELOADING" while reloading. Now write it. One more: `hasLOS` for drone detection: also require player not dead. Drone patrol target y: terrainH+10+sin. Initial drones spawn at t=0 → patrol around outpost; player 150m away — will not engage until closer. Toast at start: "RECON: ELM OUTPOST BEARING 214° — 150m". Compute bearing text. Also compass marker shows it anyway. On first engage: msg. Also when player within 110m of outpost first time: toast "ELM GRID AWARE OF YOU". Now let me produce the final code. Ensure no backtick collisions in shader strings (use template literals carefully; inner GLSL doesn't have backticks). Inside addSway replace, we use template literal with ${wExpr} etc. Potential pitfall: onBeforeCompile injection string contains `#include ` which must match exactly. Also for grass/fern Lambert with alphaTest: sway fine. Ground material: MeshLambertMaterial({map:mossTex, vertexColors:true}). mossTex.repeat? Bake repeat via uv scaling ×7 (tile 8m). Texture wrap repeat. Bark uv: cylinder uv v along height; set barkTex.repeat.set(1,2)? Since geometry shared across instances with different heights by uniform scale — texture stretch OK. Set repeat (2,2). Canopy map repeat 2. Also set anisotropy = renderer.capabilities.getMaxAnisotropy() min 8 on textures. Now let me write out the final file. Also add ``. Also include title screen controls grid: WASD move / SHIFT sprint / SPACE jump / MOUSE aim / LMB fire / R reload / ESC pause. Also add "goal" line: "Locate the ELM outpost. Destroy its core. Survive the drones." Final code — start. (When writing chunk building, don't forget to skip trees where openness is high; also vines only attach to trees we kept.) Also compute chunk ground color paint: ```js const cGrassA=new THREE.Color('#4a6123'),cGrassB=new THREE.Color('#68752e'),cDirt=new THREE.Color('#6d5836'),cRock=new THREE.Color('#7c7f6d'),cMud=new THREE.Color('#4a4331'); per vertex: const w1=fbm(wx*0.045,wz*0.045,2), w2=fbm(wx*0.016+7,wz*0.016-3,2); tmp.copy(cGrassA).lerp(cGrassB,w1); if(w2>0.62) tmp.lerp(cDirt,clamp((w2-0.62)*4,0,1)); slope: s=1-nrm.getY(i); if(s>0.25) tmp.lerp(cRock,clamp((s-0.25)*3,0,1)); if(hfiring=false)`. Also add small CSS animation on title (flicker) and button hover. Deliver. **EMERALD PROTOCOL** — an infinite procedural jungle you can walk, with chunked terrain, wind-swayed trees/foliage/vines (custom vertex-shader injection), procedural textures & models, fully synthesized WebAudio ambience (wind, birds, howlers, drone hum, guns), an ELM-9 outpost AI that launches hunter drones with predictive lead-firing, and pooled particles/bullets for performance. ```html EMERALD PROTOCOL — Infinite Jungle

``` **What's inside** - **Infinite world** — chunk streamer (56 m tiles, seeded hash noise fBm) builds/disposes around you, 2-per-frame budget so there are no hitches; everything is deterministic per seed. - **Jungle** — 2 procedural tree models (trunks + branches merged, blob canopies with baked AO vertex color), instanced grass, ferns, hanging vines and rocks; wind is a GLSL sway injected into the Lambert vertex shader (pivot-aware: canopies sway at the top, vines swing from their anchor). - **Textures/sky/water** — all generated on canvas (moss, bark, canopy, blades, vines); custom sky shader with sun disc, exponential haze fog, pooled water plane, falling leaves + pollen motes. - **ELM-9 AI** — the outpost launches drones with a patrol→engage state machine, terrain-aware line-of-sight, and an engagement brain that *leads its shots* using your velocity, narrows its dispersion as lock builds, and fires in bursts. Drones orbit-strafe you, hum in stereo by distance, and die into falling, exploding wrecks. - **Combat** — hitscan rifle with tracers, recoil, reload, hitmarkers; drone projectiles are pooled and dodgeable; destroy the glowing core (60 HP) to shut the grid down. - **Audio** — 100% synthesized: wind gusts, bird calls, howler monkeys, footsteps, gunfire, drone hum with stereo panning, lock-on beeper, explosions. - **Performance** — instancing everywhere, shared geometries/materials, pooled bullets/particles/tracers, capped pixel ratio with automatic quality drop, HUD draw-call counter so you can watch it stay lean.
