D&D Scenes Series, Part 3

I'm going to spend some time explaining the image on the right, and how to construct it. It's designed specifically to showcase what can be done with linedefs. 

What's special about the image is that it makes use of transparency. You can see through the bars to the person behind them. It also has an upper area and a lower area, which are independent of each other in terms of texture use (mismatched in the image on purpose to show this).

To the right, you see the Doombuilder room that gives you the above image. In Sector Mode, I created four sectors. Right click on any sector (while in sector mode) and you can set the floor and ceiling heights.

1) The big outer room. 
Floor height = 0
Ceiling height = 128

2) The smaller squares. 
Floor height = 128

Ceiling height = 128

3) Rectangle between the two squares

Floor height = 32

Ceiling height = 88

Linedef Sides: The image above shows how Doombuilder knows what textures go to which areas. Each linedef has two sides, a front and back. The blue circled area has a little mark that denotes the front.

The upper and lower areas do NOT support transparency. However, the middle area does, and that's why you can see through it.

Try this for your self in Doombuilder, see how it goes. Hit me up with questions when you get stuck!
