Campaign/Diplomacy AI

[nikolai1962]

Second thing...

May be obvious to people but just in case it isn't--if you want a faction to start as a vassal of another faction then you can rig the campaign AI file to make them do it in the first turn.

Say you wanted milan to be a vassal of hre for example.

1. Make a copy of the "catholic" profile in the campaign AI file
2. Rename it "catholic_milan"
3. Assign milan the ai_label "catholic_milan" in the strat file.
4. Add this clause at the top of the "catholic_milan" profile's <defend decisions> bit.

<decision_entry>
<min_entry stance="AtWar" target_faction="hre"/>
<max_entry stance="AtWar" target_faction="hre" turn_number="4"/>
<faction_attitude want_peace="true" want_be_protect="true" defense="defend_deep"/>
</decision_entry>

4. Repeat the process for hre, copy the catholic profile, rename the copy and assign it to hre.
5. Add this clause to the top of the new "catholic_hre" profile's <attack decisions>

<decision_entry>
<min_entry stance="AtWar" target_faction="milan"/>
<max_entry stance="AtWar" target_faction="milan" turn_number="4"/>
<faction_attitude invade="invade_immediate" invade_priority="1500" want_offer_protect="true"/>
</decision_entry>

6. Start hre and milan at war.
7. Make sure there's no milan diplomats around.
8. Start an hre diplomat next to milan
9. Job done.


edit: The order in which the two factions move may matter. The faction you want to be a vassal needs to have one turn to process their decison entries and decide they want to be a protectorate. So if the boss faction moves first their diplomat will be turned down on turn 1 (turn 0 in the code). Not sure if that would affect things. If you want it to definitely happen on the first turn then the "vassal" faction has to have their turn first.
