You could just use the createcylinder parameter in blitz. If you create multiple cylinders, at slightly different sizes, and use the add blend mode, you can get some decent beams going.

thats really cool but not what i was meaning, i mean a hit scan weapon, one that picks the target then creates the beam to the length that the target is away from the origin
