how to get the screen to update in a while loop

beta-byte

So I was trying to rotate a color rect until it hit 0 and made this.
while(get_node("ColorRect").get_rotation() > 0): get_node("ColorRect").set_rotation(deg2rad(rad2deg(get_node("ColorRect").get_rotation())-2))
But when I do that it just waited a bit than snaped to 0. I think whats happening is that its that it isn't updating the screen while it doing it. So that's what I want to know how to do.

You wouldn't use a while for this. If you are calling it in _process() or _physics_process(), then whatever code is running (whether in a loop or not) is considered only for the next frame. What you could do is change the "while" to an "if" and then it will rotate a little bit each frame until it's done. A better way would be to use Tweens or the AnimationPlayer.
