I want to scale a circular object so it looks like its rotating in perspective (like a record on a turntable)
I'm a little confused as to where the scaling comes into play, if you're simply trying to rotate an object. Maybe I'm not understanding the question correctly.
If (using your example) you're trying to rotate an object, like a record, I would simply use the rotate behavior.
If you're trying to then give that object some kind of wobble effect, like an old record on a turntable, I would experiment with effects, or look into using animated sprites for both the rotation and wobble.
