如何在Roblox中让脚本只在加入时工作

我该如何让以下Roblox Lua代码在加入时运行？我尝试包裹一个connect函数，但这会使MouseButton1Click检测器停止工作。

这是加载游戏时的代码，我尝试将其包装在` Players.PlayerAdded:Connect(function（player）)) 中，如下：

localPlayer.CameraMode = Enum.CameraMode.Classic
MainMenuGui.Enabled = true
localPlayer.CameraMaxZoomDistance = 400
localPlayer.CameraMinZoomDistance = 0.5

以便它看起来像：

Players.PlayerAdded:Connect(function(player)
    localPlayer.CameraMode = Enum.CameraMode.Classic
    MainMenuGui.Enabled = true
    localPlayer.CameraMaxZoomDistance = 400
    localPlayer.CameraMinZoomDistance = 0.5
end)

但是MouseButton检测器也不起作用了。抱歉我不擅长发布问题，只需要一些帮助！

quitButton = script.Parent.QuitButton
playButton = script.Parent.PlayButton
mainFrame = script.Parent
MainMenuGui = mainFrame.Parent
localPlayer = game.Players.LocalPlayer
Players = game:GetService("Players")

localPlayer.CameraMode = Enum.CameraMode.Classic
MainMenuGui.Enabled = true
localPlayer.CameraMaxZoomDistance = 400
localPlayer.CameraMinZoomDistance = 0.5

playButton.MouseButton1Click:Connect(function()
    MainMenuGui.Enabled = false
    localPlayer.CameraMode = Enum.CameraMode.LockFirstPerson
    localPlayer.CameraMaxZoomDistance = 0.5
    localPlayer.CameraMinZoomDistance = 0.5
end)

我的研究包括在Roblox论坛上检测玩家加入或角色加入。另外，在哪里放入加入检测器脚本，它是本地脚本吗？我尝试将其放入服务器脚本、角色脚本和玩家脚本中。
