Adding some actions.Move Movie Clip - Flower to place on Movie Stage where You want your flower to be drawn.(normally, it's a center of Movie (Document) Stage)Now You have knowledge about polar coordinates to draw a flower. You just need to program it. I have done it for You. Select flower on the stage ( just mouse left-click on MovieClip ) and press F9 to bring up it's actions. Put this actions (if you want just paste this actions you should turn to Expert Mode before.)
