Dungeon Generator
Prompt
Write a procedural Dungeon Generator in p5.js. It should create a random dungeon with 5 rooms connected by corridors on a 30x30 grid. Show each tile with a suitable sprite to show room interior, room walls, corridors and corners etc. Show an overhead isometric view.
A system prompt was added to support web rendering

## Features
1. **Procedural Generation**: Creates a random dungeon with 5 rooms of varying sizes connected by corridors on a 30x30 grid.
2. **Isometric View**: Renders the dungeon in an overhead isometric perspective for a 3D-like appearance.
3. **Tile Sprites**: Different visual representations for:
- Room floors (brown with texture)
- Corridors (gray with grid pattern)
- Walls (dark brown with brick texture)
- Corners (darker brown with texture)
4. **Interactive Controls**:
- "Generate New Dungeon" button to create a new layout
- "Toggle Grid" button to show/hide the grid lines
5. **Visual Legend**: Shows what each color represents in the dungeon.
6. **Responsive Design**: Works well on different screen sizes.
The algorithm ensures rooms don't overlap and are properly connected with corridors. Walls and corners are automatically generated around the rooms and corridors to create a complete dungeon structure.Drag to resize

This procedural dungeon generator creates a random dungeon with the following features:
**Core Features:**
- Generates 5 random rooms on a 30x30 grid
- Connects all rooms with L-shaped corridors
- Automatically adds walls around rooms and corridors
- Renders in isometric view for a 3D appearance
**Visual Elements:**
- Different tile types: empty space, floor, walls, corridors
- Walls are rendered as 3D blocks with proper faces and lighting
- Floor tiles have subtle texture lines
- Color-coded tile types for easy identification
**Algorithm:**
1. **Room Generation**: Creates 5 rooms with random sizes (4x4 to 8x8) at random positions
2. **Room Validation**: Ensures rooms don't overlap with existing structures
3. **Corridor Creation**: Connects each room to the next using L-shaped paths
4. **Wall Addition**: Automatically places walls adjacent to floors and corridors
5. **Isometric Rendering**: Converts grid coordinates to isometric projection
**Controls:**
- Press SPACE to generate a new random dungeon
The isometric view provides depth and makes the dungeon appear three-dimensional, with walls rising above the floor level. Each generation creates a unique layout with different room positions and connecting corridors.Drag to resize
Here's a complete p5.js dungeon generator with an isometric view. It creates 5 connected rooms with corridors and uses different sprites for walls, floors, and corners:

This code creates a fully functional dungeon generator with:
1. Random room placement with size variation (4-8 tiles wide/long)
2. Automatic connection between rooms with corridors
3. Proper wall placement around rooms and corridors
4. Corner tiles at room corners
5. Isometric 3D view with:
- Raised floor tiles for walkable areas
- Tall walls for boundaries
- Different colors for different tile types
- Camera controls (click and drag to rotate)
You can refresh the page to generate a new random dungeon layout. The code prevents room overlaps and ensures all rooms are connected through corridors.Drag to resize

This code generates a 30x30 grid and creates 5 random rooms. It then connects these rooms with corridors. The grid is then drawn in an isometric view. Different tile types are represented by different colors.
To run this code, simply copy and paste it into a p5.js sketch. You can adjust the grid size, number of rooms, and tile size as needed. The `setup` function is called once when the sketch starts, and the `draw` function is called continuously until the sketch is stopped.Drag to resize
