Tweener.addTween

Welcome

I have a problem with Tweener.addTween

Stock rotates from right to left. I want to rotate from left to right

How to do it?

Sorry for my english

rotateIt function (e: MouseEvent): void {

photo.rotationX = square_mc.rotationY = square_mc.rotationZ = 0;
Tweener.addTween (photo, {"rotationY": 180, time: 1, onComplete: Next});
