This course will teach you how to create a complete raycasting engine from scratch. We'll use an algorithm similar to the one used in Wolfenstein 3D. The final project will be coded using both jаvascript and C. It will implement player movement, 2D map view, 3D wall projection, textured walls, sprites, and other optimization techniques.
This course will be divided in two important parts
1. The first part of the course uses jаvascript to cover the theory and the math behind the raycasting algorithm. jаvascript is a simple high-level scripting language that helps us not get too distracted with implementation details.
2. The second part of the course uses the C programming language to implement a compiled version of our raycaster, including textured walls and sprites. We'll also use C to discuss important optimization and performance aspects of our code.
The tools you'll need
You'll need a web browser that can run jаvascript and a small C compiler. All these tools are cross-platform, so you can follow along with either Windows, macOS, or Linux!
The Wolfenstein 3D raycasting algorithm we'll learn is heavily based on trigonometry, so make sure you have pen and paper ready for the lectures. I will make sure we review and understand every formula we find along the way!
Is this course for you?
This course has no prerequisites. We'll cover all the math and the code as we go along, so even beginners with no prior experience are welcome to join!
How is this course different?
Other raycasting tutorials out there are either too long or overwhelmingly complex. This course tries to be as beginner-friendly as possible.
We never skip any of the math or any other implementation detail. Everything is always taught from scratch, and you get to see the code evolving line by line in front of your eyes!
