How to script an entity spawner?

Hello,

If the script above by "imnotaguest1121" did not work then try out my idea!

Connect Function When NPC Dies

Make a spawner anywhere in the map wherever you want and make the Zombie NPC and parent it to ReplicatedStorage. Make a script in the Zombie that connects a function() to an Humanoid.Died Event when zombie dies, you can obtain that by:

Humanoid.Died:Connect(function()
-- script here
end)

When the humanoid dies what you can do is Clone() the Zombie from ReplicatedStorage and set the position of the zombie to the spawner's Position. After about 2 - 5 seconds after the Zombie death you can :Destroy the Zombie.

Specific Amount Of NPC's

If you want a specific amount of Zombies, lets say about 5 then you can put the new cloned NPC's in a NPC folder and then count the children and add one if there is not enough Zombies, this will be obtained by:

-- References --
local NPCFolder = game.Workspace.NPCFolder
local NPC = game.ReplicatedStorage.Zombie
local MaxZombies = 5

-- functions --
while wait(0.5) do 
    if #NPCFolder:GetChildren() < ( MaxZombies + 1 ) then -- Counts Zombies
        local NewNPC = NPC:Clone() -- Clones Zombie
            NewNPC.Parent = game.Workspace.NPCFolder -- Parents Zombie to folder
        NewNPC.Position = Spawner.Position + Vector3.new(0,4,0) -- Sets Position
    end
end

Spawn a NPC after the Old NPC's Death

if you want one or more Zombies but they spawn after the Zombies in Workspace die what you can do is:

-- Variables --
local Humanoid = script.Parent:FindFirstChild("Humanoid")
local NPC = game.ReplicatedStorage.Zombie
local Spawner = game.Workspace.Spawner

-- functions --
Humanoid.Died:Connect(function() -- connect function when Zombie dies
    local NewNPC = NPC:Clone() -- Clones NPC
    NewNPC.Parent = game.Workspace -- Parents NPC to Workspace
    NewNPC.Position = Spawner.Position + Vector3.new(0,4,0) -- Sets position
    wait(3)
    script.Parent:Destroy -- Destroys previous Zombie
end)

I hope this Helps!

Oh sorry! I didn't read that, anyway here Is a simple script:

local NPC = game.ReplicatedStorage. --ObjectNameHere
local spawner = script.Parent

while true do
  local Clone = NPC: Clone()
 Clone.Parent = workspace
 Clone.Torso.CFrame = spawner.CFrame
 wait(3)
end
