How to make an NPC despawn after a certain amount of time?
I am trying to make a spawner that spawns zombies, but the spawner fills up the workspace with too many zombies at a time and the game gets laggy. I want the zombies to despawn once they have not been attacked for more than a minute.
Here is the code below. (The problem with this is that this despawns the zombie after 60 seconds, regardless if he has been attacked or not.)
local zombie = script.Parent.Parent wait(60) zombie:Destroy()

Use the Debris service.
The Debris service has a method, AddItem(), made specifically for what you're trying to accomplish. AddItem() has two parameters:
The Instance to be added to Debris.
A number indicating the amount of time (in seconds) the Instance will last.
Example of using Debris:AddItem():
local Debris = game:GetService("Debris")
local part = Instance.new("Part")
part.Name = "Temporary"
part.Parent = workspace
Debris:AddItem(part, 5)
In the above code, part is added to Debris and it will last 5 seconds before being removed.
the following script will delete the zombie after death or when not damaged after 60 seconds
wait()
local zombie = script.Parent.Parent
local humanoid = zombie:FindFirstChildOfClass("Humanoid")
local healthcap = 100
local timetodelete = 60
repeat wait(1)
timetodelete = timetodelete - 1
if humanoid.Health < healthcap then --reset the timer to 60 after taking damage
timetodelete = 60
end
healthcap = humanoid.Health --find their current health
until timetodelete <= 0 or humanoid.Health <= 0
if humanoid.Health <= 0 then
wait(3) --give the zombie extra time for their corpse to appear before removal
end
zombie:Destroy() --delete zombie after 60 seconds when left undamaged or killed
