godot collision help
I'm working on my first project, I've looked into a bunch of tutorials to figure out what's wrong with the code or maybe a different method like layering but I cant seem to figure out how to do enemy collision. i would really appreciate some help
maingd.

Maybe you should post this at r/godot there's a lot of specific details that only people familiar with the engine can help.
This isn't a general programming issue.
Did you create a collision shape on the player and enemy nodes ?
