Call of Duty 7: Creating Gametype

New Gametype

When making a new gametype, you'll want to keep in mind a short abbreviation that'll be used for your filenames and referenced inside text files. (ie. TDM for Team Death Match, CTF for Capture The Flag, GUN for Gun Game)

When working on your gametype, you can and are encouraged to use your mod folder as a working directory. You can copy any files you need from the \raw directory to your mod folder and edit it there.

When linking your mod FastFile, any files in your mod folder take precedence over \raw files.

Examples you can look at include Hide And Seek (Beta) and Juggernaut (Beta).

Minimum

The core files you'll need to get your gametype running include the following below.

File	Action	Purpose
<root>\raw\maps\mp\gametypes\_gametypes.TXT	Edit This File.	List your gametype abbreviation here.
<root>\raw\maps\mp\gametypes\<YOUR_GAMEMODE>.TXT	Create This File.	UI strings for your gametype.
<root>\raw\maps\mp\gametypes\<YOUR_GAMEMODE>.GSC	Create This File.	Your gametype script.

UI Support

File	Action	Purpose
<root>\raw\mp\gametypesTable.CSV	Edit This File.	List your gametype here under the fileshare and basic training lists.

Testing The Gametype

You can run your gametype through the UI, or set it by changing the dvar g_GameType (ie. /g_GameType HNS) You'll then need to launch a map, or if you're already playing in a map, do a map restart.

If you notice the game going into Free For All even when you set the gametype dvar to your own, you might have forgotten to include _gametypes.TXT in your Zone Source or there might be a script error. Check the console for any errors.
