One Way Wall -- by Pud  of NightBreed

The QuakeLab - http://www.in2nett.com/stevefu/QuakeLab

Editor used for this example:  WorldCraft 1.1a

TEXTURES: clip (and others of course, but this one was necessary for the effect)

ENTITIES: func_illusionary, func_door, func_button, trigger_teleport

PURPOSE: 
	I came up with this idea when showing someone how to make a walk-through wall.  I created a big block in the middle of a room as a func_illusionay and started walking through it.  I noticed that while in the block you can't see the block but those outside of it still can.  It struck me that this could be used as a one way mirror thing, of course without the mirror part.

WHAT TO DO:
	The way I made this example was to make a room with one wall open into a larger room.  Fill this room with a brush and make it a func_illusionary.  That's it for the simple version, but I went on to make it a bit more practical.  The only was into the room with the illusionary brush is to teleport into it.  This prevents any confusion of having to initially walk through a wall and makes it seem more like you are in a room rather than inside a wall.  Also I made a window that prevents walking out of the room through the open wall.  I just used the "clip" texture so you can still shoot through it but not walk through it.  Then I added a door that toggles open and closed, just for affect.

OPTIONS/NOTES:
	I recommend teleporting into the room with the see through wall for affect.  The "glass" window is nice so that the room maintains a "room" feel.  The toggleable door also gives the person inside the room protection when those outside begin shooting back (yes, they CAN shoot back at you).
