(Doom Builder) Switches (For Doors)

HIGHER QUALITY: http://revver.com/video/1007108/doom-... In Doom, switches are seen often and work great as puzzle devices and being able to perform actions such as opening doors and lowering platforms from afar. This video will show you how to achieve the door-opening effect so that you can implement it into your map. You will also learn how you can create the switches so that they actually require keycards/skullkeys in order to be activated! Switches can be used for many other actions, too, whether it be raising staircases, lowering platforms, activating lifts, and more. NOTE: Always remember that when choosing a linedef action for your switch, you must select one that begins with 'S' which signifies that the line acts as a switch and performs the actions listed after the 'S' !
