How do I create rotating bullets without changing path

Hi. I tried to add the Rotate Behavior and change the Angle every tick on a asteroid with Bullet behavior but then it circles around but I want it to fly in a straight line (and change after collision with solid object) but still rotate the sprite slowly so its not a static sprite. How can I do this?

Animation?

Or

pin your objAsteroid to a helper object (that has the bullet behavior attached) - now it should be possible to rotate your Asteroid.

Great idea! Thanks. I will try the pinning.
