How to test the relationship between two nations in scripts?

[zxiang1983]

I'm trying to write a script to make an "ally support" feature. Once two factions have a relationship better than, for example, "Amiable", the script can trigger an event and then both of them can build a building. Once the building is finished, you can get some unique units from your ally.


Now the problem is I don't know how to test the relationship between two factions.

If I_CompareCounter (relationship_between_england_france) > 0.5
set_event_counter relationship_amiable 1


How can I describe the red part?

I find "FactionStanding" condition in docudemon files but I don't know how to use it.

Any help is appreciated!

Well there's no independent condition for that, FactionStanding needs to be declared in a monitor_event using an event that exports both a faction, and a target faction, such as FactionWarDeclared.
You can trigger on those events and use counters to store the value though.

Thank you, Alpaca!

I think I've found a proper event:

Identifier:         UpdateAttitude
Event:              A faction to faction attitude update has occurred (once every round)
Exports:            faction, target_faction
Class:              ET_UPDATE_ATTITUDE
Author:             ScottL

But I still don't know how to use the "FactionStanding" condition. Actually I don't know the grammar of this condition.

Identifier:              FactionStanding
Trigger requirements:    faction, target_faction
Parameters:              logic token, quantity
Sample use:              FactionStanding > 0.0
Description:             what is the standing (relationship) of a faction towards the target faction
Battle or Strat:         Either
Class:                   FACTION_STANDING
Implemented:             Yes

Can I write it like this? When you use france, and your relationship is good with England, then send a diplomat to england and negotiate for several rounds, then the relationship_amiable will be triggered. Do you suggest any other better event than UpdateAttitude to use?

set_event_counter relationship_amiable 0

monitor_event UpdateAttitude FactionType england
and TargetFactionType france
and FactionStanding > 0.0
set_event_counter relationship_amiable 1
end_monitor

Thanks again, Alpaca. You are so warm hearted!

Yes, I think that should work. It'll only be triggered once every turn though, just keep that in mind

Hmm, I got a very similar question as asked in this thread. I would like to make a script that makes an allied faction to automatically declare war upon my enemies if relations are very good. What is the easiest way doing this?

I think the best way is probably fiddling with descr_campaign_ai_db.xml

You should make a new condition there near the top and give a huge invasion priority.
