This post explores the ray casting algorithm used in first-person games and provides a step-by-step guide on how to implement it in your own game using Rust. It explains how ray casting works by tracing a path from the player to the closest wall in each column of their view, and then converting the distance to the height of a wall. The post also covers aspects such as implementing player movement, fixing perspective issues, adding depth with shadows, and optimizing code size.
