Cheating-Death Client Documentation

Cheating-Death Client Documentation

www.unitedadmins.com/cdeath.php
This documentation is geared towards Cheating-Death v4.15.x

NOTICE

Unfortunately, the Cheating-Death (C-D) anti-cheat system is incompatible with servers that run VAC (Valve's own anticheat also known as "secure" servers). As of version 2.2.0, C-D can work with VAC supported MODs as long as VAC is disabled. Otherwise, C-D will try to prevent the connection or shutdown if VAC is detected. Never try to connect "secure" servers with C-D client running! If you see a message "Connection to VAC secure server has been aborted.", C-D just saved you from a global ban. Take this warning seriously.

Installation

Cheating-Death (C-D) can be installed in any directory you like.

Uninstall

To uninstall C-D, Uninstall "Cheating-Death 4.15.0" through "Control panel -> Add/Remove Programs" or execute "UninstCD.exe" in Cheating-Death directory.

Configuration

C-D has added a cd_fps command to allow you to modify the number of visual tests performed. On many computers the number of visual tests performed has very little impact on FPS. However, if C-D is reducing your FPS to an unacceptable level, modifing cd_fps may help. You should try to keep the number of visual tests as high as possible because it reduces the chances of visibility problems. cd_fps has the following values:

     0 - Maximum visibility tests (same as #6)(default)
     1 - Level 1 visibility tests (Minimum tests)
     2 - Level 2 visibility tests
     3 - Level 3 visibility tests
     4 - Level 4 visibility tests
     5 - Level 5 visibility tests
     6 - Level 6 visibility tests (Maximum tests)

You can modify cd_fps by pressing the "~" key while playing the game. This should bring down the console. In the console enter in "cd_fps", a blank space, the value you wish, and then press the enter key. Press the "~" again to return to the game.

To see what your current cd_fps level, press the "~" key while playing the game. This should bring down the console. In the console enter in "cd_fps" and then press the enter key. The current value of cd_fps will be displayed in the console. Press the "~" again to return to the game.

C-D has added a cd_sound command to allow you to modify how C-D removes non-visible players from the screen. On some systems, the method chosen can affect the sound. cd_sound has the following values:

     0 - This uses the new method of player removal. (default)
     1 - This uses the old method of player removal.

You can modify cd_sound using the same method as for modifying cd_fps.

Running

Run cdeath.exe, and then start your game however you normally start it.

Optional Mode for Listen Servers

This information only applies to people running listen servers. If you are only using C-D to play a game, then this does not apply to you. C-D has added an optional mode. There is now a cdrequired server rule. You many switch between optional and required mode at anytime by changing the cdrequired cvar. To persistently set this variable, add it to your listenserver.cfg file. The default mode is required or:
cdrequired 1

You can put C-D into optional mode at any time by entering the following command:
cdrequired 0

You can modify cdrequired using the same method as for modifying cd_fps.

When C-D is in optional mode, it will not kick anyone for not having C-D installed. When a player does not have C-D installed, "[No C-D]" will be prepended to their name. When a player has an older version of C-D installed, "[Old C-D]" will be prepended to their name. When a player has the correct version of C-D installed, their name will not be changed.

An easy way to tell who has C-D installed is to look at the scoreboard. (The default scoreboard key is the tab key.) By looking at the player's names you can tell who is running C-D.

If you switch from optional to required mode, all of the players not using C-D will be kicked.

Credits

Many people deserve credit for Cheating-Death.

Botman - Much of my overall understanding of how the half-life game works comes from Botman's HPBBot code. His tutorials and source code provided my basic education in Half-Life MOD development. (www.planethalflife.com/botman/)

ClientBot Programming Board - Much of my detailed understanding of how the Half-Life game works comes from the participants of the ClientBot board. Vasily, System, DeltaShark, ReDucTor, Quabalah, and many others have been very generous in sharing their knowledge, ideas, and code.

Others - I have also picked up good ideas from many other forms, websites, and people. The people on our development mailing list have provided many excellent ideas.

I hope I am not leaving anybody out.

I know that no client-side add-on will ever be able to stop all of the cheating. But maybe it can make the game more enjoyable, and without a lot of hassle. It is my hope that we have been successful.
