Godot Community

I have an issue. I'm currently working on my game and doing some early movement animations work. I was trying to animate attack but animation is playing only if I hold the space button. If I just press it, it plays only the first frame. I tried many solutions but they didn't work. Maybe you can help me? I'm using this script (I don't really remember it but I hope you'll understand)

Elif Input.is_action_pressed("ui_accept"):
if attackAnimation==1:
$AnimationPlayer.play("attack1")
attackAnimation=2
Elif attackAnimation==2:
$AnimationPlayer.play("attack2")
attackAnimation=1

I'm coding in GDS for about 2 days now. I've used different engines before but godot is the first one I really seem to like and enjoy using, I just need to learn the main coding language. I theoretically know what and how the code is supposed to work I just don't know how to "translate" it to GDS. Maybe you remember how you've learned this language or maybe you wish you've learned it in some way?
