Walt This basically makes internal weapons possible. Some kind of bubble weapon like err.. a blast going outward.
btw. There's feature-bug regarding beams if I set the spawn location outside the ship. The simulation is fine but the beam is displayed at the edge of the part instead of the spawn location.
Also note if you ever consider making these parameter accessible. It can be used for shield to cheat regarding (energy) bullets as they get destroyed regardless of energy power. I guess a boolean parameter is needed and they need the same damage subtraction treatment as with penetrating & hitting parts.
