I hope mE don't mind me posting his port on my plugin here on amxmodx forum
Bouncy grenades ported by mE @ psix.info
Originally by lillbrorsan:
This is a simple plugin that makes the grenades from gl bounce and glow.
kl_bounce = On(1) Off(0)
kl_bouncy = Change how much the grenade should be able to bounce around
Tested on both windows and linux with AMXX 1.01 as well as AMXX 1.60.
(Requires the engine module - should be on by default)
Old movie of the plugin in action:
