Nice thanks most of it works, but now:
Problem 1: The width of the Laser increases proportionate.
Idea 1: Setting the position every 0.1 seconds to Fly.ImagepointX(0) and the same with Y doesn't really solve it.
Problem2: The Laser does not reflect on collision with the Wall (TiledBackground 3)
Idea 2: Tried playing around with Imagepoints of the Laser, but does not really work because i cannot say "IF Imagepoint 2 [Right side of the laser] collides with wall" its only possible with "IF laser collides with wall" which would take the origin.
Do i have to play around with Variables?
Edit: I know ANGLE is not really what i should use with a Laser, but dont know what I could use instead.
