Hi!  I'm trying to restrict immigration in my mod to the smallest amount possible without actually stopping it completely.  So far all I've managed to do is put [ITEM_THIEF] on the civ in question, which should in theory stop the civ from gaining any exported wealth from traders, but this doesn't really seem to work very well.  Can anyone suggest anything else?

Not entirely sure what you mean here. You are saying that, in said mod, once you have a fortress-type game started you want to slow immigration down to a trickle? Like, one newcomer per season (or less if possible)?

[Lofn]

Ah, yes, sorry, I should have been clearer.  That's exactly what I meant.

You can set a population cap. When it's reached, no more immigrants will come, (excepting nobles). However, there is no way to lower the rate of immigration.

Well, the pop cap is kind of broken sometimes, but it is broken in a way that can be put to your use.

I read somewhere on these forums - and have confirmed to my own satisfaction - that if you set the pop cap to a point somewhere above your current population, then the game will calculate the number of dwarves needed to reach that population - and then keep sending that number (assuming your fortress wealth would merit the immigration in the first place) each season regardless if you have exceeded your Pop cap.

You could set the population limit to something like eight - that way you should only receive one immigrant per season, and as long as you keep the limit there it shouldn't change too much. I haven't done a vast amount of testing on this issue but I've observed it more than once.

So... yeah. You could give that a try.

[Lofn]

Excellent, thanks.  I'll give it a try and report back.

The POP_NUMBER values might affect immigration numbers. Haven't tested it though. Would need to regen.

In a non-modding sense, you could try forbidding lots of general wealth stuff as forbidden items don't count towards your wealth.  If you just made it a habit it might not be too tough, but I imagine you are looking for a modding solution.  You could just do a mass change to item values so general wealth is smaller overall.
