How do I reapeat once per loop?

Question

So I'm working on a platformer game, with the animated sprite node in Godot 2.1. And I have it like so:

(Not actual code)

func fixed_process ():
  If right key pressed:
    Set animation to walking

Problem is that it sets the animation to itself so many times it doesn't actually loop.

Please help!

Answer 1

var anim_state = "idle"

func fixed_process():
    if right key pressed and anim_state != "walking":
        Set animation to walking
        anim_state = "walking"
