This is pretty funny. I'm not sure what SS is getting at with bounding boxes... when we do a check to see if object A is inside object B, we are testing the bounding box of A against the bounding box of B. Its not Is the origin of A in the bounding box of B. The fact that someone has a velocity of say 1000 (definately not unreasonable thanks to grapple flings) and the laser only has a small width, its possible for someone to be on one side of the laser during one think and on the other side of the laser at its next think. The only sane way to check for that is to increase the think speed of the laser, all the way up to the one check per frame if necessary. It was always my impression that people liked the possibility to skill through lasers or I probably would have fixed it. It was kinda like when we fixed turret grenades so that they wouldn't miss ducking players and then ended up putting it back because people considered the bug a feature :/
