I want to create effects for this game, but I don't know where to start

I’m trying to recreate the scan and outline effects from the game Lurking, but I’m having a hard time because there aren’t many examples available.

If I create the outline using Shader Graph, I don’t know how to create the scan effect. And if I create it using shader code, it’s very difficult to create an effect that detects the outlines of objects like cubes.

There are videos of the Lurking effect being created with shaders in Unreal Engine, but I’m a beginner with shaders, so it’s difficult for me to follow along.

Is there a definite way I can learn how to do this? I have so many questions and I don’t know how to create these effects.

The easiest is probably full screen shaders for the effect and then you can use whatever you need for the outlines
