                 Lesson 5 : Split Star Trek doors		                   
=====================================================================
Purpose:
   A tutorial on making Split Star Trek doors in Duke Nukem 3D using 
   Build. Note that a Star Trek door and a Split Star Trek door are 
   two different kinds of doors. I explained ordinary Star Trek doors
   in lesson 4 (door9.zip).

Step 1:
   Make a regular Star Trek door.

Step 2:
   Move the ceiling and the floor of the door sector. Point at the 
   door and press 'PgDn' to move the ceiling down. Point at the little 
   triangled area of the door sector that is still visible when you 
   look at the floor, and press 'PgDn' to get the floor up. Choose a
   cool texture for the door.

Step 3:
   Let the ceiling and floor meet together halfway. You're now
   finished with constructing the split Star Trek door. Now we're
   ready to add the finishing touches.

Step 4:
   Give the door sector a Lo-Tag of 26. Add a Speed sprite and
   a Music&SFX sprite as necessary. Again you'll get to hear the
   sound twice when you open the door. I guess there's no way to
   fix this problem. Either accept the buggy sound or make the door
   silent.
