The ThiefControl plug-in is an attempt to force decent play with regard to the thief flag. It is designed to prevent teammates from stealing flags from one another by forcing the player to drop his or her thief flag and invalidating the steal. There are, however, different rules for different game modes. The following table describes the behavior of the plug-in for each game mode.
|Game Mode||Plug-in Behavior|
|Team FFA||Teammates cannot steal any flags from each other. Rogues are exempt from this rule.|
|Capture the Flag||Teammates can only steal team flags from each other. Rogues are exempt and can steal anything from anyone.|
|Open FFA||Anyone can steal from anyone. The thief flag can be used in any desired way.|
|Rabbit Hunt||Hunters cannot steal from each other.|
ThiefControl is included in the source code for BZFlag 2.4.
