Buy Desert Script local UnlockButton = script.Parent.SurfaceGui.UnlockButton local ReplicatedStorage = game:GetService("ReplicatedStorage") local RemoteEvents = ReplicatedStorage.RemoteEvents local DesertDoorBought = RemoteEvents.DesertDoorBought
UnlockButton.MouseButton1Click:Connect(function() --Fires when you click the Unlock button wait(0.1) DesertDoorBought:FireServer() end) DesertDoorBought.FireServer:Connect(function() end)
