well, in the manual it says that the collision hull doesn't change im guessing thats your problem, the engine doesn't know that it hit the other model becuase collision detection doesn't work, so i thought if you have a box thats as big as the beam(im guessing thats what your scaling?)and use that for collision detection. oh and wouldn't that just make it scale so the beams x is the same as the enemys x? tonight I'll look at the code and see if i can come up with something.
