Capture the Flag

Capture the Flag is the name of a game played with two teams, each with one flag. Each team's goal is to take the other team's flag and bring it back to their own flag, scoring a point and returning both flags to their original positions. However, if you bring your opponent's flag back to your flag and your flag is missing, your flag must be returned in order to score. You drop a flag when killed, and when picked up, dropped flags return immediately to their appropriate flag stand.

The CTF Standard
The modern CTF Standard is, at this point, an informal agreement between ZDaemon and Skulltag which allows CTF maps that are compatible with each other. It started as the result of a conversation between Alex "AlexMax" Mayfield and Brad "Carnevil" Carney, with a proposal by Carnevil to make CTF maps easier to make for Skulltag, seeing the explosion of popularity of CTF mapping in ZDaemon. From there, AlexMax convinced both Carnevil and the administration of ZDaemon to both implement what is now known as the CTF Standard.

The CTF Standard consists of a list of agreed-upon thing IDs for player starts and flags to use. These are as follows:


 * Thing ID 5080: Blue Start
 * Thing ID 5081: Red Start
 * Thing ID 5130: Blue Flag
 * Thing ID 5131: Red Flag

A mapper creating a CTF map must ensure these things are found in the map, and their map will work in both ZDaemon and Skulltag. However, due to a bug in Skulltag, if a Player 1 or Deathmatch start is present anywhere in the map, the level will not work properly. Carnevil has stated that this behavior is considered a bug and will be fixed in a future version. As of ZDaemon 1.08 and Skulltag 0.97d, the CTF standard has been implemented in both source ports.
