-- die LUA ermöglicht beliebig viele Tore auf der Map.
-- Ausserdem kann man die Richtung und den Weg des Tors bei jedem Trigger einzeln einstellen.
-- Version 2:
-- .. Im Singleplayer ist es nun möglich die Tore per Tastendruck offen zu halten bis erneutem Tastendruck. 
--    Im MP nimmt alles seinen gewohnten Gang wie bisher
