Character not cloning every 0.1 seconds?

Clone works if the model Archivable property is true and by default player character isn't so you must add the code.

The code here is tested in studio non FE enviroment.

game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        Character.Archivable = true
        local clonedCharacter = Character:Clone()
        while wait(0.1) do
            clonedCharacter.Parent = game.Workspace
        end
    end)
end)

That will clone the player character.

this script... it's pretty outdated.

First, you don't need 2 functions. Here is the fixed codeL

workspace.ChildAdded:connect(function(obj)
    if obj:FindFirstAncestor("Humanoid") then
        for i = 0, 100, 1 do -- set the middle number to how many times you want this to run
            local a = obj:Clone()
                a.Parent = workspace
        end
    end
end)

the clone's parent wasn't the workspace, so it wasn't appearing.

If you want to just use your code, then do:

game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
    while wait(0.1) do
    local hehe = Character:Clone()
    hehe.Parent = workspace
     end
end)
end)

If this helped, please accept answer. :D
