Is there a way of making grenades explode after their lifetime, but making the counter start as soon as the grenade is thrown? IE not when it stops moving.

Try looking at the time bomb's odf. Might not give you the exact answer your looking for, but might give you a starting point.

@RED51...Nope...not useful at all.

I think there's a bit of ODF code that does it, no idea what it is though....

Ahhh thank yee Syth, Knew there was a code for it just didn't know what it was.
