7. Loading Your Map in the Game

It's the moment we've been waiting for, and there's no description for the pure w00tness that you'll experience when you run around in your own virtual world for the first time. It's something you'll never forget...like your first kiss.

Anyways, quit Hammer first. That's right, close the sucker. I don't care whether you have a monster computer with fourteen processors all linked together, Hammer uses a lot of resources, and Counter-Strike:Source isn't very stable when both Hammer and the engine are loaded at the same time. Running them both is a good way to crash your computer.

Fire up CS:S, and after you bring up the console, type map firstmap and Enter. Wait for a few tantalizing seconds, and watch your creation spawn. If you encounter an error message when attempting to load the map, read this FAQ.

Did you hear the angels sing? Congratulations, you made your first map! I know it's not an incredible looking map, but we all got to start somewhere.

Have fun feeling claustrophobic and shooting at the brick walls around you.

By the way, your screenshots are located in the directory:
SteamApps\<your steam id>\counter-strike source\cstrike\screenshots.

Now that you built your first room, it's a good idea to get acquainted with the Dimension and Scale in Hammer next.
