Shaders for PIXI.Filter

[s1ckwell]

Hello guys, I am a frontend developer that trynna make my own game on Pixi 8 so I know nothing about game developing and rendering with WebGL in general. Now I have a static game demo with no animations.

My game just has a constructor that creates a character from vector sprites and uses some masks and geometries to color different parts of the a character. In this case coloring works fine with just static geometries and masks but I want to add some animations and as I figured out by researching info, I need to use custom filters with my own shaders to color animated sprite and apply textures with some patterns. BUT, as I said I know nothing about creating and using shaders. I've tried to make some with ChatGPT help, but just got infinite erros which I don't know how to fix and what even these errors mean. So can you guys help me out by sharing some info about using shaders in Pixi or how to write shaders in general. I've found this guide https://webglfundamentals.org/ about WebGL but it's too difficult to me to understand and figure out how to solve my problem just by myself. 

And if someone can create shaders, please share just a simple shaders that apply texture on an animated sprite. Appreciate for every help.
