This appendix contains reference material for using QuArK, as well as details about how to use map2dif, the utility with Torque that's used to generate Torque DIF files. The Map Editor When you launch QuArK, you immediately get the QuArK Explorer window. This is your jumping-off point from which you can get to the various main features of the program. The most important feature of QuArK is the Map Editor, which you have already encoun- tered, shown in Figure D.1. tip Whenever you see the text "Press F1 for help" in the hintbox at bottom left of the window, you can press F1 and get a larger hintbox that gives some information about the item under the cursor. These hints are especially useful if you are new to QuArK and you have forgotten the function of some visible feature in the window. Press F1 to get a quick hint to refresh your memory. Move your mouse out of the hintbox to make it disappear. Remember our previous sidebar discussion of structures vs. interiors and maps vs. rooms in Chapter 17? After all the terminological torture, it boils down to either a part of, or the entire, 3D world in which you play your games. So in the context of developing our game for Torque, we use QuArK to make structures or interiors. In the context of QuArK as a non-specific development tool, we make maps or rooms. The difference lies in how you use them. Team LRN Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. The remainder of this chapter is about how to use many of the features of QuArK. We will stick to the QuArK terminology so that the words here match the words in the program. A map is made out of mathematical polyhedrons in 3D space. As mentioned earlier, these are also called brushes. Brushes will present in your game as a wall, floor, ceiling, furni- ture, or anything with a fixed collidable 3D shape. Weapons, lights, and other entities are not made out of brushes, and you cannot use the Map Editor to build their shape. note A polyhedron is a solid figure bounded by plane polygons or faces. Cubes and pyramids are specific variants of the polyhedron. QuArK has a formidable array of features, and an equally formidable menu bar. In this section we can make them a bit less formidable with tables for each menu describing their functions. The File menu, as shown in Figure D.2, is pretty much your stan- dard File menu with some QuArK-specific features. Table D.1 contains an itemized description of the menu.
