yes, those, does anyone if there is a way to have code make a window in a wall, so that, like you see in a wall, you can see in, or out, but cant see through the wall. i know of one way to do this, which is drawing the wall around the window, so that it leaves out that space, but i doubt this is a very good-looking way to do this...anyone know what to do?

There's no simple way to just not render a portion of a polygon. You're going to want to use an editor of some sort and model the hole yourself using CSG or the like.

If you don't have a program to make maps, I suggest you get GtkRadiant and learn how to use that as well as its maps. Good luck.

Alternatively you can use the stencil buffer to do CSG subtraction, but that's not really feasible in most cases in a gaming environment.
