It applies angle 180 to it, this is no bug. Try to make an event "every tick" and action Sprite set angle to Sprite.angle + 1, you'll see the natural course that leads the sprite to be "head over heels".
But, this allowed to see that auto-mirror and auto-flip don't seem to work. If you set them in the project, the image doesn't flip or mirror. Kyatric2011-11-17 02:41:29
