Laserturret

Hey Guys
I’m trying to make a laserturret. I am using a particlesystem. 2 problems. 1: I want the “Laser” to follow a curveguid, until it is completely out of the turret. Not, that when the turret is rotating, the laser ermittes in the air next to the turret. 2. problem: I want, that the laser is comming out of the Ermitter. At the moment it is already appearing behin the ermitter.

Thanks for your help guys.
