Go ahead and start the map editor. You will be greeted by a familiar splash screen. The editor integrates directly with the game engine, and it puts it to some pretty cool uses. The splash screen will disappear to a black window once loading is complete. If the window starts out maximized, double click on the top blue bar to resize it down. (When maximized, the editor simply stretches the image over the screen. This can confuse you when you try clicking around or zooming in and out, so it’s easiest to just use the default size.) Under the File menu, select New. A dialog box will appear.
