Hi. I have a very simple question.

I have a Sprite (RefreshButton) that I want to rotate 360 degrees after it has been pressed. I'm detecting whether it's been clicked like so:

func _input(event):
    if event is InputEventMouseButton:
        if $RefreshButton.hovered:
            if event.button_index == BUTTON_LEFT:
                if not event.pressed: # button up
                    $RefreshButton.spin()

Now, the problem is, the only way I know how to make that animation play, is to have a _process(delta) method constantly check whether it needs to be played. Like so:

var spinning: bool = false
var rotation_speed: int = 1000

func spin():
    spinning = true

func _process(delta):
    print(spinning)
    if spinning:
        rotation_degrees  = delta * rotation_speed
        if rotation_degrees > 359:
            rotation_degrees = 0
            spinning = false

This seems very unoptimal (requires a function that constantly checks whether the animation should be played, even though we know exactly at which point it should start), and what's worse, with more animations, it makes _process(delta) method extremely bloated.

What is the proper way of achieveing this, without having a method that's constantly running in the background?
