Roguelike: Synthesis

Combine all four map generation algorithms behind a strategy enum — switch generators and regenerate maps with new seeds at the press of a key.

Chapter 1

Algorithm Switcher

Combine all four generators behind a single enum and add keyboard-driven regeneration. Switch algorithms with arrow keys and generate new maps with spacebar.

The Strategy pattern lets you swap algorithms at runtime -- a fundamental design pattern used everywhere from game AI to rendering backends.

What You'll Build

You will combine all four map generation algorithms behind a single enum-based strategy selector. A match statement routes to the correct generator, and pressing a key regenerates the map with a new random seed. This part is about architecture — how to organize multiple algorithms behind a clean interface so they are interchangeable at runtime.

Learning Goals

✓Enum definition for generator strategy selection
✓Match statements for routing to different algorithms
✓Seed regeneration with a keypress callback
✓Shared interface pattern: all generators write to the same grid format

Tips

✨Define a clear generate(grid, rng) interface that all four algorithms follow — this makes swapping strategies a one-line change.
✨Print the current seed and algorithm name to the console for easy debugging and reproducibility.
