Langton's Ant Simulation

A Bevy-based implementation of Langton's Ant cellular automaton with a clean, modular architecture.

Project Structure

src/
├── main.rs          # Application entry point and configuration
├── components.rs    # ECS components (Ant, Direction, GridCell, AntSprite)
├── constants.rs     # Configuration constants and colors
├── grid.rs          # Grid state management and logic
└── systems.rs       # Bevy systems for setup and updates

Features

• Modular Design: Clean separation of concerns across multiple modules
• Configurable: Easy to modify grid size, colors, and simulation speed
• Efficient: Uses HashMap for sparse grid representation
• Real-time Visualization: Smooth animation with Bevy's ECS architecture

How to Run

cargo run

Langton's Ant Rules

1. At a white square, turn 90° clockwise, flip the color of the square, move forward one unit
2. At a black square, turn 90° counter-clockwise, flip the color of the square, move forward one unit

Configuration

Modify src/constants.rs to adjust:

• Grid size
• Cell size
• Simulation speed
• Colors

Architecture Benefits

• Maintainability: Each module has a single responsibility
• Testability: Components and logic are easily unit testable
• Extensibility: Easy to add new features like multiple ants or different rules
• Readability: Clear separation makes the code easier to understand
