Rotating Objetct

Hi guys. This is probably simple but i've been trying to do this for 4 hours with no good result. Also could not find a tutorial or example capx to help me.

So here is the deal. I have a image (a tail) that i want to rotate up and down (like a dog bouncing his tail).

I have tried the Animation metod, but it is not that smooth.

Is there a way to limit the movement to an angle and them makes it come back using the "set origin and image point".

Thanks and sorry for the bad

Hi all, i solved this by adding the TURRET aquire target to an invisible sprite and made this sprite move from point to point on the screen.
