How would I make a script so that after a certain period of time parts regenerate?

local Clone = workspace.NAMEOFPARTORMODEL:Clone()
wait(SECONDS)
workspace.NAMEOFPARTORMODEL:Destroy()
Clone.Parent = workspace

you can put this in a while loop :)

Hope i Helped

You can do something like this. If you can script it should be easy to make this clone the item u want.

local regentimer = 1
local replicatedstorage = game:WaitForChild("ReplicatedStorage")

while wait(regentimer) do
print("Cloning")
local oldclone = game.Workspace:FindFirstChild("Part")
if oldclone ~= nil then
    game.Workspace.Part:Destroy()
end
wait(1)
local newclone = replicatedstorage.Part:Clone()
newclone.Parent = workspace

end

Try using this script:

local model = --the name of the object you want to clone
local modelParent = --where you want to put the cloned object]
local seconds = --time in between cloning in seconds

while true do
    local modelClone = model:Clone()
    modelClone.Parent. modelParent
    wait(seconds)
    modelParent.model:Destroy()
end

Hope this helped!
