Custom grappling hook (trail)?!
Posted: Tue Dec 30, 2008 10:26 am
Hi everyone!
I've just replaced the grappling hook by a sticky, Monkeys-of-Doom style chameleon.
Problem is that it still fires with the lightning-gun trail, which unfortunately doesn't look like a chameleon-tongue at all 
What I found in cg_weapons.c is this:
... Where
... seems to tell the game to use the lightning-gun beam and it's shader for the grappling hook. - Question is, if there is a (not too tricky) way to create a custom texture or shader to replace it...
