Im sure this will be easy to solve!

TransitionManager.start(ticker, {type:Rotate, direction:Transition.IN, duration:3, easing:Strong.easeInOut, ccw:false, degrees:180});

im using this code to rotate and object
how do i rotate around a certain point on that object?

thanks guys

when you create a movieclip you get a registry point. thats where the _x,_y,_rotation points are set!
