Raycasting Ray Setup

Blue circle: Player position
Red line: Player facing direction
Green lines: Individual rays cast from player
Yellow lines: FOV boundaries (±30° from facing direction)
Orange walls: Sample walls that rays would hit

Raycasting Ray Setup Explained

ray_step = (PI / 3) / WIDTH;
ray_angle = player.angle - (PI / 6);

ray_step: Angular increment between rays (60° FOV ÷ screen width)

ray_angle: Starting angle (player direction - 30°)

This creates a 60° field of view centered on the player's facing direction.

Player Angle: 0°

Ray Count (WIDTH): 60

Each ray represents one column of pixels on your screen. More rays = higher resolution but more computation.
