Gmod lua making custom effects

right I have been looking on how to make custom effects and how they work, I have been looking around on Garry’s Mod wiki and I need help making your own effects the type of effects I want to make is ‘your addon/lua/effects/custom effects/init.lua’ so far I know how to make a colour laser beam and that’s about it.

Might help you.

thank you, does this right lua code for you?
