How do I loop an animation in a Godot animation player?

Question

I'm trying to loop an idle animation that I have in an AnimationPlayer, but it keeps on only playing once. Is there any way for me to make it loop?

Answer 1

You can enable the Animation Looping icon:

The looping arrows is the icon that allows for toggling the looping.

Answer 2

For Godot 4, to set the animation loop mode use Animation.loop_mode

https://docs.godotengine.org/en/stable/classes/class_animation.html#enum-animation-loopmode

var anim : Animation= $AnimationPlayer.get_animation(anim_name)
anim.loop_mode =(Animation.LOOP_LINEAR)
