How to make a simple enemy AI?

Godot Version

Question

I want to make an enemy AI that follows you around for a top-down shooter. I watched like 6 tutorials and none of them worked. Also Enemy and the Player are different Subscenes and I plan on having enemies spawn in a wave system, so I need to also have multiple in a level

What do you mean none of the tutorials worked?
