The Civ4BuildingClassInfos file defines what building classes exist in the game. Building classes relate to the unique building system; a unique building has the same building class as the building it replaces.
All tags must be opened and closed; the first is the "open", the second the "close" tag. If nothing goes inside a "list tag", then it should just be the opening tag with a "/" before the closing bracket. The following tables contain all available tags, as well as their purpose and accepted values.
This page is missing information. Do not remove this notice until it is complete.
These tags typically bracket other tags, sometimes the entire file, and are generally used to specify more than one piece of data.
|BuildingClassInfo||Main bracket for each entry|
|Type||Label that is used for entry in all other XML files|
|Description||Name of default building for the entry|
|DefaultBuilding||The default building used when there is no unique building replacing it|
All of these tags have a numerical value. Though it sometimes can be negative, it usually is not.
|iMaxGlobalInstances||Number of building class that can exist in the world; used for world wonders|
|iMaxTeamInstances||Number of building class that can exist in one team|
|iMaxPlayerInstances||Number of building class that can exist for a player; used for national wonders|
|iExtraPlayerInstances||Number of building class that can be constructed if the limit has already been reached (used to allow the Palace to be moved)|
All of these can either be 1 (on, or true) or 0 (off, or false). Be careful, as you can wind up with a double-negative, which the game will interpret as "True".
|bNoLimit||Whether there is a limit on the number that can be constructed|
|bMonument||Nothing. Unused Tag.|
All List tags consist of an opening/closing tag, which is shown here, and then each entry within it is another tag with the same name as the parent tag, minus the "s" (i.e. singular, rather than plural).
|VictoryThresholds||Indirectly, sets a buildingclass as a prerequisite for a given victory type. The possible values are either NONE or the ones defined in the GameInfo\Civ4VictoryInfo file. VictoryThresholds is also used in Civ4ProjectInfo file.|
Affects the project success rate (see: iSuccessRate) and the delay rate (see: iVictoryDelayPercent). Indirectly, sets a project as a prerequisite for a given victory type. The possible values are either NONE or the ones defined in the GameInfo\Civ4VictoryInfo file.
In the following example of code, please note that there is a specific order of all of the tags. You must list the tags in this order for the game to properly interpret your file.
