How to Block Matrilineal Marriage for Agnatic Succession?

[Grave461]

How can I completely block matrilineal marriage if Agnatic Succession is enabled? I tried adding law_set_allow_matrilineal_marriage = no to the law, but doing that came up with an error in Validator. So I tried adding matrilineal_marriages = no to Feudal Governments, with the hope that it would default matrilineal marriages to "no" for feudal government types, thereby requiring any succession law that is *not* agnatic succession to be enabled in order to allow matrilineal marriages. But, that didn't work, either.

I noticed all the succession laws have law_set_allow_matrilineal_marriage = yes with the notable exception of Agnatic succession. I'm sure there has to be a way to do it, but so far I'm not finding the right solution.

Any suggestions?

TL;DR: I want to have matrilineal marriages disabled *only* for agnatic succession law; all other succession laws can have it, per vanilla.

Try adding law_set_allow_matrilineal_marriage to the effect clause of the laws.

Ok, I think I got it working now. Turns out I used the incorrect tag in common/governments. Instead of using matrilineal_marriages = no (like is found in common/religions), I needed to use allows_matrilineal_marriage = no. This prevented agnatic succession from using matrilineal marriage. Then I switched my succession law to agnatic-cognatic, and then I was allowed to use matrilineal marriage.

I'm pretty sure law_set_allow_matrilineal_marriage in common/laws will only accept a "yes" boolean value, because switching it to "no" doesn't seem to prevent matrilineal marriages.

That last part might be a bug. It's used in 00_features.txt (though it's the old 3.0 command, which was changed in 3.1). It should support it.
