Thank you, that example works great. Now one more question:

When using particles how do I keep them coming out in one direction no matter what the pan is of the object it's attached to? E.G. I have a space ship with a particle stream coming from the left and right wings. When I turn the ship the particles don't continue to shoot straight out the back like they should, they curve around to continually shoot out at one stationary point. (I want to particles to shoot at a local (ent) set of coordinates. (ship.x+100, ship.y+100, 0))
