Mapping Lessons/Functional Map

Tarquin: This page will be replaced by the Mapping Lessons sequence.

This page will teach you how to create an ugly but functional room.

Making a Cube

File –> New: If you've been fooling around in UnrealEd you'll want to work with a fresh map.
Toolbox –> Cube icon: On the left side of the screen there's a toolbar with a bunch of icons.

You'll see a box titled "CubeBuilder":

The CubeBuilder properties

Enter your size: You can enter in just about anything, but for this tutorial we want a 256x256x256 cube.
Subtract your space: Just press CTRL+S on your keyboard.

Lighting

Now you have a little hollow cube. A "room" for our purposes. But it doesn't look anything like even a basic cube you'd see in Unreal. To fix that, we need some light:

Add a light actor: Right-click within the dimensions of your cube in any veiw (A 2D view is recommended), then click "Add light here" in the menu that pops up.
Build the level: Press F8 on your keyboard, and click "Build" in the Build menu that comes up.

RDGDanClark: Can someone confirm the method by which a light (or any actor) is placed when using a 2D viewport? For instance, when placing a light in the overhead 2D view, what determines where in the Z axis the actor actually ends up?

MythOpus: Ususally, at least for me, the light is put in the center of the brush you placed it in.

GRAF1K: It is placed at 0 on the z-axis – the plane the the origin point is on.

PlayerStart

Now you have light. Your room now looks like it will in-game, but the game won't know where to put you if you try and play it now. Lastly, we need a PlayerStart:

Add a PlayerStart: Right-click within the dimensions of your cube in any veiw, then click "Add PlayerStart here" in the menu that pops up.
Build the level again: Press F8 on your keyboard, and click "Build" in the Build menu that comes up.

Now you have a finished level. Save it (File → Save) with a DM- prefix just like any other Deathmatch level, then play (Build → Play Level).
