	Hmm, it could do with some finess, but here's a capx Download I made a few quick changes, some instance variables etc. It marks the first dash and spawns the rocket there, it also deletes previous dashes once the rocket has exploded. I think there's still a bug with lerping angles, as lerping the angle to make smoother curves causes it to spin wildly as it only works in a positive direction it seems.

	You could test for the difference between angles of the line and the rocket being positive or negative, then have a sub event that interpolates in a positive or negative fashion. I did try smoothing it with LERP(Dash.Angle,Rocket.Bullet.AngleOfMotion,5) but lerp will only turn clockwise, so you'd need to filter into two sub events and test if the difference is positive or negative I think. That would smooth out the turning. :)

	Here is a way to make the rocket follow the path: http://dl.dropbox.com/u/5426011/examples12/dashed_line2.capx The dashes have a variable to indicate which rocket uses it so each rocket will follow it's own path.

	@R0J0hound I get a lot of problems with your capx, the line you draw seems to create additional segments coming off it so the rocket shoots along the line then keeps going off then back to the main line, know what i mean?
