Try keeping a list of people and what they have spawned in. Then if they already have something spawned in you can delete that vehicle and spawn in the new one. Then set the new one as the currently spawned in item. I don’t know what the Dipi variable is so I’m not going to use it.
Also, I assume your using a ClickDetector | Roblox Creator Documentation for the button.
local Players = game:GetService("Players") local Boat = workspace:WaitForChild("Boat") local Profiles = {} Players.PlayerAdded:Connect(function(player) Profiles[player] = false end Players.PlayerRemoving:Connect(function(player) if Profiles[player] then Profiles[player]:Destroy() end Profiles[player] = nil end -- whenever button pressed do: Button.ClickDetector.MouseClick:Connect(function(player) if Profile[player] then Profile[player]:Destroy() end local boat = Boat:Clone() -- The code you use to position the boat can go here boat.Parent = workspace Profile[player] = boat end Some coding suggestions I have so you can improve are to try making your code more readable as well as learning how Roblox’s API works and it’s syntax. Here’s some resources to help you learn what I covered in the code I provided:
