Breakable Glass Windows

1.  In 3D mode, create an area where you want to put your window. 

2. Next, mask it by setting your cursor on the wall just below the window opening and press the 
letter <M> key. 

3. Place your cursor upon the newly created mask and press the <V> key twice. 
Find the texture you want for your window and press the left <Enter> return key (I used
texture #263). You can change its translucence by toggling the <T> key. 

4. Now, go into 2D mode.  Place your cursor on the red line which represents your masked window, 
press the <B> key, and  then hold the left <Ctrl> key and press the <H> key (just like in Duke Nukem). 

5. Next, with your cursor  still on the line (which should have turned bright pink at this point), hold the 
left <Alt> key and press  the <F6>. This will bring up the wall dialog menu. Change the 
"Type" to 511: Gib Wall, under "Trigger On" put an 'x' in the Vector box, and under "Trigger Flags" 
change Data to 12. Now the window will  break if you hit it, but only from one side. Repeat the above data
input from just on the other side of the window lines and you should be able to break it now from both
sides.
