Citizen Automation code is where?

[MrAnon]

I'd like to tweak the behavior of the city automation (old school 'governor'). Specifically, I want to change the code controlling what constitutes an acceptable amount of food produced when non-food emphasis is active.

Demonstratum: You are producing +3 food and have production emphasized. The 'governor' will not move citizens around to increase your hammers at the expense of food, so you move a citizen from a 2-food tile to a hammer tile, increasing your production but still maintaining a +1 food surplus. Slow growth, to be sure, but growth nonetheless. The automation AI, however, will not accept that and disable itself. If you re-enable it, your citizen is moved back to the food tile.

Logically, there must be a string somewhere that tells the governor what surplus of food is adequate. Rough empirical data says that the coded surplus level is +2 food but that's not proven yet.

In any case (sorry - rambling a bit this morning) - does anyone know where the relevant code is hiding? Of course, if you can tell me precisely what changes to make, that would be extra-groovy . I'm a tech, not a code jockey so while I *can* do it, I'm not keen on poring over a bunch of lines I mostly-but-not-completely understand.

TIAFYH!

I think it's in CvCityAI.cpp. I think the function is AI_assignWorkingPlots(...), thought I haven't looked in detail at it.

If I bask in your reflected glory, will I get a suntan?

Thanks much, TGA, I think you are correct. At least, my neophyte code-reading skills lead me to think you are. I found, 200 lines past "AIassignWorkingPlots" this line: if (!AI_foodAvailable(1)) in which the original integer was 2. I changed it to 1 and am testing now to see if that's the ticket.
Nothing else looks like it would be the right instruction anyway.

I never would have looked in that subdirectory on my own so I really appreciate the guidance!
