is there a way to make a use button in a map that will kill all NPC's?
i'm not sure, but i know that you can bind a button to kill all npc's.
I didn't make it!
Just link a button to a trigger_kill. The trigger must be in the room where the npc's are. The button would activate the trigger_kill, and voila, all npc's are dead.
Trigger kill must contain: key: dmg value: 1000 Try that.
or just target the trigger_kill to the npc's you want to kill... that might work. :)
that is if it is a single player level. I don't know what you are doing. A big trigger_kill will also kill all the players if it's a MP map.
I'm not sure, but it might be possible to script it so that the button types npc kill all in the console. Don't kill me if I'm wrong, not big on scripting
Just make the huge trigger NPC only...
