I just started using godot a couple weeks ago and have been making movement code using youtube videos and have made some basic movement code I'm satisfied with for the time being. I was watching a video on making state machines (this one) [ as from what I've seen they seem to be necessary when it comes to making things like attacks and wall jumps. And I can't understand how to transfer my movement code and animations into the state machine.
If anyone has any tips on how to make the state machine function that would be very appreciated.
