CD supports certain global chat incantations that will make it display or modify aspects of its configuration on the fly.
These commands all start with the string "!cd".
Chat commands may be issued at any time CD is loaded: in the warmup session before a game starts, during a wave, during trader time, or after a game has ended.
Every chat command belongs to exactly one of two categories: CDAUTH_READ or CDAUTH_WRITE. An example of a CDAUTH_READ command is "!cdmaxmonsters", which prints the current MaxMonsters setting. An example of a CDAUTH_WRITE command is "!cdmaxmonsters 36", which sets MaxMonsters to 36.
CDAUTH_WRITE commands apply immediately when issued outside a wave (i.e. in pregame warmup, trader time, or after a game has ended). However, when a CDAUTH_WRITE command is issued mid-wave, it delays application via a mechanism called "staging". This means the command writes your modification to temporary storage without applying it to the live game configuration. It immediately responds with a string like "Staged: MaxMonsters=36". As soon as the wave ends -- either due to the trader opening, the team winning, or the team dying -- your changes are applied, and CD displays a reminder notification displaying the option name and the new value that it has just copied from temporary storage to the live game configuration.
CDAUTH_READ commands always respond immediately. CDAUTH_READ commands are aware of the staging mechanism. If a CDAUTH_READ command is issued mid-wave after relevant configuration writes have been staged, it will report both the actual and staged values.
In server mode, the INI option DefaultAuthLevel controls what anonymous users may do by default using chat commands.
If DefaultAuthLevel is set to CDAUTH_WRITE, then any user may run any command. This is intended for private servers where all users are trusted.
If DefaultAuthLevel is set to CDAUTH_READ (the default), then anonymous users may only run commands that read the configuration. They cannot run chat commands that modify the configuration.
However, a user whose SteamID is listed in any of one or more optional AuthorizedUsers lines may run any command, including those that modify the configuration.
Here's a config snippet illustrating how DefaultAuthLevel=CDAUTH_READ works with AuthorizedUsers. This snippet authorizes two users to run any chat command. Anyone besides the two listed users can run chat commands that read the configuration, but not those that would modify it.
[ControlledDifficulty.CD_Survival]
DefaultAuthLevel=CDAUTH_READ
AuthorizedUsers=(SteamID="STEAM_0:0:3691909",Comment="blackout")
AuthorizedUsers=(SteamID="STEAM_0:0:11101",Comment="gabe newell")
The AuthorizedUsers line may appear as many times as needed. Each line specifies one SteamID (which can be found with a tool like http://steamidfinder.com/) and an arbitrary comment. The comment field can be any text you want. It's just there to make the list somewhat maintainable.
Playing CD solo automatically and unconditionally enables all chat commands, both CDAUTH_READ and CDAUTH_WRITE. There's no need to edit your KFGame.ini to configure DefaultAuthLevel or AuthorizedUsers if you just want to use chat commands in solo mode.
