Greetings!
So I’ve tinkering with this analog joystick that I found in one of the posts here, but it seems to be that I’m having trouble mapping it to one of the nodes. Specifically to my player character. I tried inserting “if conditions” inside the func isPressed(event), but it doesn’t work the way I wanted.
Is there anyway to translate a character’s movement based on this joystick? I have no Idea where, or how to implement it in this code. Thanks in advance for all your help, and assistance.
