How do you make a custom npc die after a certain amount of frames?

[AlanLive2020]

When i do it, all of the npcs with the same id die at the same time. Can anyone help?

if i'm understanding you correctly, you're trying to only make a specific instance of said npc die after a certain amount of frames elapse.
if you're not well-acquainted with custom npcs, i recommend looking at "npc-n.lua" in "data/_templates".

to accomplish what you've described, simply declare a local timer variable equal to the amount of frames, decrement it in onTickNPC() and call kill() when it reaches 0.
