This works for guns, but for explosives it seems to play the sound at the breaker's eye position

This implementation doesn't really account for all of the ways this entity could break so maybe we could get the "real" origin from the bmodel, worldspacecenter or bounding box mins / maxs?

Edit: In testing just using WorldSpaceCenter() instead of GetAbsOrigin() works fine, but if you're interested in keeping the behaviour of where it got damaged I guess you'd need to check the ent that is attacking can actually fire bullets. Also not sure what would happen if the glass is broken from physics damage like entities or players smashing into it

[AdamTadeusz]

replacing info.GetAttacker with info.GetInflictor in a few places solves this problem, though at this point WorldSpaceCenter would be the neater solution
