Right now, whether or not the grenade ever touches anything on Bound Mode, it still explodes after a set time.

What i'm thinking of is just adding a little bit to the GrenadeBounce.lua so that the timer starts after it hits something, but I have no idea what.
Does anybody know if this is possible, and example code would be greatly appreciated!

You could do a check for a major change in speed, which would indicate the collision.

something like
if self.Vel.Magnitude < self.previousvelmag - 10 or self.Vel.Magnitude > self.previousvelmag + 10 then
[start timer to do the other stuff]
end
self.previousvelmag = self.Vel.Magnitude


Alternatively, you could have one non-timed grenade that gibs into the timed one, but switching objects out mid-collision makes the collision a little funky, IIRC.

Thanks, that sounds nice!
