Adapting Building modifiers to technologies

[Gun Ninja]

Greetings Fellow Fanatics

I am working on a mod and I want to add production or other various other traits to be gained by just researching a tech (say +1 food from all farms from mobile machinery (tracker)). I have tried copying traits from other xml files and their schemas to the appropiate tech files but it didn't work. I have and idea that is may have somthing to do with python files but I can't seem to find anything there to help.

TIA

You can improve the output of any improvement via the CIV4ImprovementInfos.xml file. For example, if I want farms to produce an extra food once biology is discovered, you would change <TechYieldChanges/> to this>:

<TechYieldChanges>
		<TechYieldChange>
			<PrereqTech>TECH_BIOLOGY</PrereqTech>
			<TechYields>
				<iYield>1</iYield>
				<iYield>0</iYield>
				<iYield>0</iYield>
			</TechYields>
		</TechYieldChange>
</TechYieldChanges>

Now after you discover the Biology tech, all of your farms everywhere will produce one additional food.

See, now that's the kind of stuff that needs to be documented somewhere!

Not bad but not quite what I was looking for. I would like to increase the global production yeld from a tech independent of improvments or buildings. Say like computers would modify every cities output without building a new building.

Unfortunately you can't do that with the xml files. You can globally increase health or happiness or trade routes with techs, but not commerces or yields.
