smash bros finish zoom in roblox script?

I want this script that can be like when the npc is going to die pretty much the server can tell if the npc is going to die so like when i hit the npc and he goes flying the server can tell so i can pasue the game for a second to show that the npc is going to die

if you dont understand like smash bros ultimate if they are at a high percentage and get hit the game will have a kill zoom

i think this might work:

--put this script inside the npc while true do wait() if script.Parent.Humanoid.Health == 0 then print("The NPC has died!") script:Destroy() end end
