Cutscene Creator

Thankyou for making this plugin im going to be using all the time :smiley:

Wow! Ive used this a lot, and it works so smoothly. I have one question though. Do you know how to make the cutscene only play once for a player. What I mean is that if they have already joined the game before and seen it, the cutscene wont show again. Do you have and Idea on how to do that?

How would I make it run the event when a ScreenGUI button is clicked?
I tried:

local playCutsceneEvent = game.ReplicatedStorage.CutscenesEvents.PlayCutscene

local function playIntroToJoinedPlayer(player)
	playCutsceneEvent:FireClient(player, "Intro")
end

script.Parent.MouseButton1Click:Connect(playIntroToJoinedPlayer)
