I saw, it looks great! But I was wondering if I could apply it to only a single object. I'm new to coding and GM2, I managed to get it to draw onto a surface, but the surface seems to be acting as a sort of window looking into a glitch effect that is the size of an entire screen.
I asked on the Gamemaker 2 forums, but nobody seems to know how to apply it to a single object.
The goal was to have an enemy glitch when they're shot, and I really want to use your shader for it, since it has so many options!
So basically, the issue is that the edges are getting cut off, even though my surface that I created is bigger than the object I want to draw the shader over.
