Civ4TechInfos

The Civ4TechInfos file defines all of the information, basic and complex, about each of the game's technologies. Information in this file includes a tech's prerequisites, research cost, and benefits.

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.

Tags

Headers

These tags typically bracket other tags, sometimes the entire file, and are generally used to specify more than one piece of data.

Tag Name	Description
TechInfos	This begins and ends the file. Everything must go in between these two, or it will not work.
TechInfo	Encloses the entry for each civilization

Text

Tag Name	Description
Advisor
Button
Civilopedia	References the Text which contains the civilopedia content for that civilization. The text is specified in any of the Assets\XML\Text files.
Description	References the Text which contains the civilization description (eg: "American empire", or "English empire"). The text is specified in any of the Assets\XML\Text files.
Era
FirstFreeUnitClass
Help

Sound
SoundMP
Strategy
Type	The name that can be used in other files and in the SDK to refer to a particular civilization.

Integers

All of these tags have a numerical value. Though it sometimes can be negative, it usually is not.

Tag Name	Description
iAdvancedStartCost
iAdvancedStartCostIncrease
iAITradeModifier
iAIWeight
iAsset
iCost
iFeatureProductionModifier
iFirstFreeTechs
iGridX
iGridY
iHappiness
iHealth
iPower
iTradeRoutes
iWorkerSpeedModifier

Boolean

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".

Lists (Multi-line)

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).
