I have been trying to figure out how to do cutscenes I even looked at the roblox tutorials and they just wouldn't work all I can think to say is
part = game.Workspace.Part
part.Touched:Connect(function(itemTouchingPart)
if(itemTouchingPart.Parent and game.Players:FindFirstChild(itemTouchingPart.Parent.Name))then
-- this is where i would do my cutscene code
end
end)
