I modified to add grenade attack code but grenade attack doesn't work.( I did control this snpc but only this snpc's grenade attack doesn't work.This snpc is just standing and nothing happened. Other snpc's grenade attack works fine.)
What's wrong with this code and how do i fix it?

Nevermind. It's just "npc_vj_creature_base" problem. I was do edit to "npc_vj_human_base" and problem is solved.
