I made a cutscene that shows up the Play button GUI, which allows people to play in but however, when pressed, nothing happens. Here is my code. But however, I never tried the Left Click instances before.
local Camera = game.Workspace.Camera
local Play = script.Parent
function MouseButton1Click(plr):Connect
if MouseButton1Click Play then
game.Workspace.Camera:Destroy()
end
end
Please note that it didn't use any ClickDetection.

well if you want to detect mouse button 1 click then you could use
local mouse = game.Players.LocalPlayer:GetMouse()
mouse.Button1Down:Connect(function()
CODE
end)
^^ Put that into an answer so it can be accepted.
