So the vertices' positions are in the corners of the sprite. The texture coordinates of the whole texture page range from 0 to 1. So 0,0 is the top-left corner of the texture page and 0,1 is the bottom-left corner. Typically a sprite's texture coordinates will be somewhere in the middle of the texture page. Understanding this helps with shaders because these are the inputs the shaders have to work with. Shaders are graphical programs run on your GPU that handle drawing of sprites, surfaces, vertex buffers, etc.
GM supports two types of shaders: the vertex shader and fragment shader sometimes called pixel shaders. When you don't apply any shader, GM uses a default "passthrough" shader. This passthrough shader outputs the texture with the draw color and alpha the way you're used to. Shaders process all vertices simultaneously and then all the pixels.
If you right-click the shader in the resource tree, you have three options to choose from:. I've gone through the default vertex and fragment shader, but I replaced the comments with my own.
This will give a basic explanation of what each line does, but don't worry about the details just yet. Vertex shader code quickly explained:. Okay, so now you have a shader, but how do you use it?
