# Raycasting

A small raycasting example demonstrating grid-map collision, player rotation and movement, textured wall projection, and a minimap rendered into the CPU pixel buffer.

Controls:

- Arrow Left / Arrow Right: rotate the player.
- Physical A / D: alternate rotation controls.
- Arrow Up / Arrow Down: move forward and backward.
- Physical W / S: alternate movement controls.
- Gamepad left stick or d-pad: rotate and move.

The example casts one ray per screen column against a tile map, projects the nearest wall hit into vertical strips, and samples simple wall textures. The minimap shows the map, player position, facing direction, and a subset of the cast rays.
