					local CurLine = dialouges[line]
					istalking = true
					for i = 1,#CurLine[1] do
						script.Parent.DialougeHolder.Dialouge.Text = string.sub(CurLine[1],0,i)

					if CurLine[3] then
						CurLine[3]()
					end
					istalking = false
					line = line +1
				else
					local CurLine = dialouges[line]
