Help With a Plugin

Hi I am using a plugin called Cutscenify

i am using the executable script option, i used it for a button, but how do i make sure that if a player clicks it all the players on the server see the cutscene, i would like to make everyone see it, not just who click it,

i tried with getplayers () but it doesn’t work …

LOCALSCRIPT UNDER THE BUTTON

local Cutscene = require(game.Workspace.EICutscenesAPI)

function leftClick()

Cutscene:PlayFullCutscene()

end

function rightClick()

print("Wrong click")

end

script.Parent.MouseButton1Click:Connect(leftClick)

script.Parent.MouseButton2Click:Connect(rightClick)

Hope you Can Help Me!

You would need to use a RemoteEvent in order to tell every other client to play the cutscene. See:
https://developer.roblox.com/en-us/articles/Roblox-Client-Server-Model
https://developer.roblox.com/en-us/articles/Remote-Functions-and-Events

Can you send me an example of what the script should be?

In a server script (in server script service, and not in the UI.):

-- services
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Players = game:GetService("Players")

local CutsceneReplication = ReplicatedStorage:WaitForChild("CutsceneReplication")

CutsceneReplication.OnServerEvent:Connect(function(Player)
	-- You should REALLY perform some server validation here to make sure that this player is authorized to start the cutscene, and that there is not one happening already.
	for _, TargetPlayer in pairs(Players:GetPlayers()) do
		if TargetPlayer ~= Player then
			CutsceneReplication:FireClient(TargetPlayer)
		end
	end
end)

At the top of your LocalScript in the button:

-- services
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local CutsceneReplication = ReplicatedStorage:WaitForChild("CutsceneReplication")

In your LeftClick function:

CutsceneReplication:FireServer()

At the bottom of your LocalScript:

CutsceneReplication.OnClientEvent:Connect(function()
	Cutscene:PlayFullCutscene()
end)
