Need help with Shade code line
Hi there, I'm new to programming and godot, and right now I'm trying to implement this GLSL shader in godot and having troble with it.
This is the line I'm struggling with:
float pattern = tri(fract((uv.y + time / 12.) * 20.0), 2.0 / divisions, divisionsShift)- (-uv.y + 0.30) * 0.85;
I want to put it in godot programming language, but i can't find a replace to the tri function that works similar.
Again, just a beginner here, but i would appreciate some help. Thanks!!
