Godot Community

You can use AnimationPlayer's "Add Track -> Call Method Track" in animation API ,

It will excue the the func you set after "attack1" finished .

First I made some easy starter project from the web, maybe use the one in the docs, to get comfortable with the sytax, but chose something you enjoy but isnt difficult. Then I used the Godot Documentation and just started coding. Its really about testing it out and I find the docs really helpful for that. Sometimes i watched, especially when i didnt knew anything about tilemaps, some videos how you are supposed to use it or the godots node system in general.
