Now, imagine we have a for loop that goes over every vertex and runs the code inside the vertex shader for each. This leaves us with six vertices per sprite, but two of those are the same one, so we should only worry about four. Each sprite is formed by a rectangle, but computers like to draw triangles, so those rectangles are split into two triangles. However, I came up with an analogy that made it much simpler for me to think about them. When I first started learning about shaders, I had a tough time getting my head around how they work. This difference comes with its own set of rules and limitations, but we'll cover those later.Įach shader is made up of two separate scripts: a vertex shader and a fragment shader (also referred to as pixel shader). Shader code is similar to regular code, but it is (almost always) run by the GPU (your graphics card), not the CPU (your processor). Initially created to provide shading for lighting (hence the name), they are now used to produce a huge variety of effects.
They are also among the most advanced features offered by GameMaker Studio 2, but I will try to explain everything as simply as possible in this post.
