ExecChangePeopleProdMod [new](People#,PeopleGroupOwner#,New Prod Mod in %,Which ProdMod? 1,2,3,4?)
Q1: If I want to raise the level of regimes production by 10% I'm do this ...
with no noticeable effect.
Q2: The last variable (I've got it set to '1' for no particular reason) can apparently be 1,2,3 or 4. What do these refer too?
Re. Q1, Q2: I use ExecChangePeopleProd [old]. The difference is this. With ATG item types could be set to be different prod types. That is type 1, 2, 3 or 4. In standard AT(WW2), there was only prod types 1. The [old] exec only uses prod type 1.
So the 1, 2, 3 or 4s refer to the people groups production of a particular item. This can be useful if you say want PPs to be produced at the same rate if conquered, but standard equipment to be produced at less rate if conquered. I believe this is what is done in standard ATG (random games).
If you are only using one prod type, like most AT scenarios (or ATG WaW) then using the old exec is better.
