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.)
1 | local zombie = script.Parent.Parent |
2 |
3 | wait(60) |
4 | 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():
1 | local Debris = game:GetService("Debris") |
2 | local part = Instance.new("Part") |
3 | part.Name = "Temporary" |
4 | part.Parent = workspace |
5 | 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
01 | wait() |
02 | local zombie = script.Parent.Parent |
03 | local humanoid = zombie:FindFirstChildOfClass("Humanoid") |
04 |
05 | local healthcap = 100 |
06 | local timetodelete = 60 |
07 |
08 | repeat wait(1) |
09 | timetodelete = timetodelete - 1 |
10 | if humanoid.Health < healthcap then --reset the timer to 60 after taking damage |
11 | timetodelete = 60 |
12 | end |
13 | healthcap = humanoid.Health --find their current health |
14 | until timetodelete <= 0 or humanoid.Health <= 0 |
15 |
16 | if humanoid.Health <= 0 then |
17 | wait(3) --give the zombie extra time for their corpse to appear before removal |
18 | end |
