                 *** Tempest's BUILD Tutorial ***
                 Lesson 11 : Making light switches
=====================================================================
Purpose:
   A Tutorial on making light switches in Duke Nukem 3D using Build.

Step 1:
   Put a switch sprite on a wall (point at wall and press S, press
   V twice to browse through all the textures).

Step 2:
   Point at a wall, floor or texture, and press Alt and keypad minus
   to make the sector darker. The light switch does not have to be
   in this sector at all.

Step 3: 
   Put a sector effector (sprite #1) on the floor, point at it and
   press Alt and keypad plus to make it brighter. The brightness of
   the sector is the brightness of that sector in the game when the
   lightswitch is off. The brightness of the sector effector is
   equal to the brightness of the sector in the game when the light-
   switch is on. 
   Now make sure the lo-tag value of the lightswitch (Alt-T) is the
   same as the hi-tag value of the sector effector (Alt-H). Give
   the sector effector a lo-tag value of 12. You can light up multiple
   sectors with one lightswitch by adding a sector effector with
   the same values in all the sectors.  
   Uhm..well, that was easy, wasn't it?
