I did
local Blue=workspace.Blue
Blue.ClickDetector.MouseClick:connect(function()
local Btb=Instance.new("TextButton")
Btb.Parent=game.StarterGui.ScreenGui
Btb.Size=UDim2.new(0,70,0,70)
end)
I know I went wrong by putting it under StarterGui since I figured out that it works once you die. Is there a service that makes the Gui appear when you insert it?
