I implemented state machine following a tutorial by Nathan Lovato and youtube, and player movement such as run, jump, airjump, and idle works perfectly fine.
I am now trying to change state when player enter enemy’s area2d by state_machine.transition_to("").
However, an error the identifier "state_machine" isn't declared in the current scope pops out. I would appreciate if you could teach me how to fix this and change state when area entered.
