Ray Casting Tutorial Part 4 Permadi This document explores the fundamental theory behind ray casting, a pseudo 3 dimensional rendering technique that are very popular in game development arena in the 90s. How to make a simple 3d game (raycaster) in scratch. this is part 1 of a short series where we build a level arena maze and learn how to code player movement. One of the most common tasks in game development is casting a ray (or custom shaped object) and checking what it hits. this enables complex behaviors, ai, etc. to take place. this tutorial will explain how to do this. To find the first wall that a ray encounters on its way, you have to let it start at the player's position, and then all the time, check whether or not the ray is inside a wall. if it's inside a wall (hit), then the loop can stop, calculate the distance, and draw the wall with the correct height.
