[Submod] Peace Treaty Script (Realistic Expansion) *testers appreciated*

[CIaagent11]

That's odd, it seemed to work well in my testing. I definitely haven't seen iberians in gaul in quite a while. Maybe this scripting just doesn't work very well in TW games, as someone said in another thread. In that case, there's nothing I can do. But the freezing effect of 1.3 does not get applied if one of your armies or settlements is close to the faction, so that you don't fight enemies that are frozen. So maybe you had an army around Thrace? But that does not seem to be the case with Massilia or the Cantabri. You are nowhere close to them. Also, factions are blocked from attacking smaller neighbors, but if smaller factions eat each others, then the bigger factions then attack those medium factions and get really big. The cantabri might have taken that settlement from Massilia, I dont think they are forbidden from going to war. Or you caught an old version. I uploaded a new version just now, that might even out some bugs and uses attrition first, and only freezes a faction later. That should make the map somewhat more movable.

Thing is the possibilities to effectively influence the AIs diplomatic actions via script are very limited in Rome 2.

Interesting might be to change the CAI personalities for example make them less aggressive after they have reached a certain threshold.

force_change_cai_faction_personality

Thanks for the suggestion, I will look into it. It would make sense to start out with low aggression and raise it as the campaign moves on. But I have no idea how to work with the force_change_cai_faction_personality command, and I had no luck finding out what the possible values are.

I would recommend people who are using this to download the latest version, I've eradicated some bugs that more or less broke the battle bonuses and silently updated via mediafire.

force_change_cai_faction_personality(faction:name(), "cai_personalities_table_key");

force_change_cai_faction_personality(faction:name(), "cai_personalities_table_key");

I see, thanks. Unfortunately I don't know which ones are allowed for which factions. And I don't know which of those would make them more or less aggressive. The options seem rather limited. I can see that for example gaul minor seems to have a few options, from friendly to warlike. But others do not.

I have idea about Peace Treaty Script.
Between minor faction 2~5 years random Peace Treaty (like 30%, 40% 50% chance) - it represent petty war among minors
Between major faction 5~20 years random. It represent hegemonic war.
Between Majaor vs minor 5~10 years random. It represent conquest

[CIaagent11]

Thanks for the suggestion. You mean a random peace between factions at random intervals? The peace wouldn't last long. They just go to war again as soon as they can, if they hate each others. The AI routine basically goes "if not at war, randomly declare war on a faction you hate". The AI will always be as virulently expansive as you let it. If you stop it from expanding into one direction, it will just go around and expand in whatever direction it can according to that set of new rules.
To make factions have peace over several years, it would be necessary to save that faction combination in a variable in the savegame. It would be a boondoggle to implement and not really do much.

Is there any way to add relation bonus when they make peace treaty?

[ragnar23]

not peace between factions at random intervals. it could be 2 years war or 5 years war. (ex minor faction) by cheking X% chance of cease fire.

I recommend everyone to update. All versions prior to now had a bug that crashed the script when a character did not have a region.

[Sedulus]

Here I have a screenshot where the Apulii, already again or still spread so much ... Like the Sequani. These invade regions where they are not supposed to be. I will continue playing the game with the new version, and let's see what else happens. It is round 68.

[CIaagent11]

Must be because they expanded while you had the version with the region log bug. Seems the Apulii precisely expanded within the area the peace treaties allows them to be in. Just the pending battle part wasn't working. Don't expect that to change now, I think nobody around them can go to war with them.

If this version doesn't work, then I don't know what will. I eradicated the bugs now. It works well in my test campaign, and the logs all respond what they're supposed to. I'll post a screenshot later.

It seems the power of the win_next_autoresolve_battle isn't infinite though. Apparently sometimes the strengths are just too mismatched for the autoresolve scripts to turn that into a victory. I can't do anything about that. For example in my last campaign, Massilia was lost to the Volcae, even though the log said that the script ran to the end and gave a win bonus to to Massilia. That seems to be rare though.
Also, the check whether factions are in enemy territory is still wonky. Because in_enemy_territory only updates on the next turn, so they can go conquer stuff if they reach the enemy within the same turn of being in their own territory. I've tried to work around that, but it's not perfect.

You can check major_log.txt in your Rome 2 folder. If you can find the battle where things went wrong, you can check whether the script was runnign to the end. If it says "finished autoresolve bonuses" at the end of a pending battle paragraph, then it didn't crash.

Then I will have to start again or a new game after all.
This file does not exist in my folder.

[CIaagent11]

It does, because the script creates it. Go to C:\Program Files (x86)\Steam\steamapps\common\Total War Rome II\major_log.txt

Seriously, this file does not exist for me.

[CIaagent11]

I thought about it. The DeI team uses this line to make Rome and Carthage enemies:
scripting.game_interface:cai_strategic_stance_manager_promote_specified_stance_towards_target_faction("rom_carthage", "rom_rome", "CAI_STRATEGIC_STANCE_BITTER_ENEMIES")
So I assume there must be a way to use the same line to make factions friends. Unfortunately I do not know what the other cai stances than BITTER_ENEMIES are; the Attila scripting guide doesn't tell us, and I had no luck finding anything when searching for it.

[Sedulus]

News from the front...
Somehow this still does not really work for me. The Eblani and also before the Demetae landed in Spain. See the screenshot.
I noticed that I had an alliance with both of them, but I did not ask for help. The AI independently declared war on Carthage. One would have to forbid the AI to declare haphazard wars. In my current game, Carthage is at war with the half card. Factions from Britain, with Illyrer, with Knossos and I still know everything. It is one thing to declare war on a faction, but what else can send armies there? The Breuci have at one time 4 regions ripped off by the Lusitani not to mention. If there were not every now and then revolts where it would be "normalize" halfway, it would look bad. And as it looks like, not much happens at the Lusitani and the Breuci.
What comes to mind when I looked at the script again. Could not you tell the fractions about the script when to attack who? That works with the reforms and with the money too. Only as an idea ...

[CIaagent11]

I put up a new file, try that. But I dont think it changes much. Other than that, the battle effects just sometimes dont take effect. It would probably be way easier to just tell the AI to be less aggressive via cai policies, but I don't know how to mod that.

[Sedulus]

And what have you changed in the file now?

[CIaagent11]

The check whether pending battle combatants are in enemy territory works now, even if they have been there for just one turn, meaning that bonuses get applied properly. Other than that some rewriting that makes the code prettier, but doesn't really change functionality so much. Oh, and there is an attrition functionality now for factions that are overexpanded by more than one settlement. There is no harm in updating, t is perfectly save game compatible.
