Help to change diplomacy

Where can I find the script for diplomacy? I don't like wars no one is fighting.

I would like to change war weariness to much higher value ( to end endless wars) and higher values for winning battles (to stay in a war they are winning) if something like that is possible.

The section of the script you are looking for is 25. Campaign AI Label Triggers. There is no trigger for winning battles, only for losing them. All the things that increase war weariness are losing battles, being besieged and recruiting lots of units.

Note that the switch back to warlike is a simple random chance (8% chance a turn), so you need to increase that as well if you don't want them to spend long periods nursing their wounds.

I will raise weariness for small factions to make them more reasonable. I cant make them to accept peace and I think other factions have a similar problem. How much WarWeariness they need to switch to peaceseeking?

If I add this code for every faction and simply copy it into one of WarWearines monitors, will they get one aditional point every turn or I need to do something else?

Code: [View]

if I_EventCounter faction_turn_f_nabatu > 0 ; it's the faction's turn
and I_EventCounter f_nabatu_PeaceSeeking < 1 ; faction is in a warlike state
inc_counter f_nabatu_WarWeariness 1 ; so increase war weariness
end_if

Is it safe to remove parts about ships to make naval warfare count? Most of factions stuck in wars they dont fight are at coast after failed naval invasions.

Code: [View]

  ;; Faction is winning/losing battles ;;


    monitor_event PostBattle TrueCondition     ; checking after a battle has been fought
        and not I_ConflictType Naval ; exclude naval battles


;; Faction's levels of recruitment ;;

    monitor_event UnitTrained TrueCondition                ; a unit has been trained
    and not TrainedUnitCategory ship                ; exclude ships

Yep, safe to remove those. The threshold is 6, it's in a lower section (as > 5).

Maybe I just have to lower that one to 5 to see some peace. Or I will change threshold to 40, give them one WarWearines point per turn and raise points for SiegeStress, battles and recruitment to 8,7,8. This way they should have similar stances as before + they should try to end wars after 10 years even if they dont fight it.

Problem is that I want active wars with aggressive factions to stay. Can I remove WarWeariness points like this ?:

Code: [View]

 ;; Faction is winning/losing battles ;;


    monitor_event PostBattle TrueCondition     ; checking after a battle has been fought
        and not I_ConflictType Naval ; exclude naval battles
        if I_EventCounter faction_turn_f_rome > 0    ; it's the faction's turn
            and not I_WonBattle f_rome                        ; faction lost a battle they initiated
            and I_EventCounter f_rome_PeaceSeeking < 1 ; faction is in a warlike state
            inc_counter f_rome_WarWeariness 1          ; so increase war weariness
        end_if

Code: [View]

 ;; Faction is winning/losing battles ;;


    monitor_event PostBattle TrueCondition     ; checking after a battle has been fought
        and not I_ConflictType Naval ; exclude naval battles
        if I_EventCounter faction_turn_f_rome > 0    ; it's the faction's turn
            
            and I_EventCounter f_rome_PeaceSeeking < 1 ; faction is in a warlike state
            if  not I_WonBattle f_rome                        ; faction lost a battle they initiated
                 inc_counter f_rome_WarWeariness 7          ; so increase war weariness
            else                                                             ; faction won a battle they initiated
                  inc_counter f_rome_WarWeariness -5          ; so decrease war weariness 
            end_if
        end_if

In almost 300 turns long campaign I have seen one message about peace and one alliance. Only one diplomat was send to me with trade agreement proposition and noone aked for ceasefire. Rome, Carthage, Numidia and gauls take my peace offerings as very generous, and yet they are unable to ask for it or end their own wars between each other. Switch between war and peace works correcty, but if negotiations are extremly rare, no wonder there is no political development.
Cant there be a problem with diplomats? Where can I find changes to diplomats and what war and peace stances do?

Another thing - in first monitor "monitor_event PreFactionTurnStart FactionIsLocal" there is section at end which changes AI stances for all factions to peacefull. This breaks some campaigns, for example as KH I made peace with Pyrrhos, alliance turn later, we captured Korinthos together (KH without much of a loss Epeiros had no army left) and then I moved on Demetrias. Makedonia and Epeiros ruined after 10 turns and I was unstoppable. I should be shaking for my life for years during that war.

All the details on behaviour is in the descr_campaign_ai_db - that defines default, diplomacy and warlike states.

The CAI does does do weird things with grouping diplomats together, and there's a cap on the maximum number per faction - see "Agent restrictions and others"

Not all factions are changed to peaceful - just those who are supposed to start out in the peaceable stance:

Code: [View]

    monitor_event PreFactionTurnStart FactionIsLocal
        set_counter f_rome_WarWeariness 6
        set_counter f_carthage_WarWeariness 6
        set_counter f_baktria_WarWeariness 6
        set_counter f_hayasdan_WarWeariness 6
        set_counter f_pontos_WarWeariness 6
        set_counter f_parthia_WarWeariness 6
        set_counter f_lusotannan_WarWeariness 6
        set_counter f_saba_WarWeariness 6
        set_counter f_saka_WarWeariness 6
        set_counter f_sauromatae_WarWeariness 6
        set_counter f_numidia_WarWeariness 6
        set_counter f_pergamon_WarWeariness 6
        set_counter f_gandhara_WarWeariness 6
        set_counter f_bosporan_WarWeariness 6
        set_counter f_nabatu_WarWeariness 6
        terminate_monitor
    end_monitor

Also note it's in a monitor that terminates on game-start, so it only sets them once. It also lines up with this section in the "startup" script (which again terminates at the start of the game):

Code: [View]

        ; Starting AI stance event counters
        set_event_counter f_rome_PeaceSeeking 1
        set_event_counter f_carthage_PeaceSeeking 1
        set_event_counter f_baktria_PeaceSeeking 1
        set_event_counter f_hayasdan_PeaceSeeking 1
        set_event_counter f_pontos_PeaceSeeking 1
        set_event_counter f_parthia_PeaceSeeking 1
        set_event_counter f_lusotannan_PeaceSeeking 1
        set_event_counter f_saba_PeaceSeeking 1
        set_event_counter f_saka_PeaceSeeking 1
        set_event_counter f_sauromatae_PeaceSeeking 1
        set_event_counter f_numidia_PeaceSeeking 1
        set_event_counter f_pergamon_PeaceSeeking 1
        set_event_counter f_gandhara_PeaceSeeking 1
        set_event_counter f_bosporan_PeaceSeeking 1
        set_event_counter f_nabatu_PeaceSeeking 1
        terminate_monitor

I have read descr_campaign_ai_db but it only says when they want peace. I know they want peace, because they gladly accept it, but they dont send diplomats to other factions with proposal. Some time ago I suggested that assassins do nothing and they should be more active. I was told they were overactive in previous versions and there is no desire to go back. Can I ask how this change was achieved for my personal edits?

Sorry, I didnt noticed Epeiros and Makedonia arent in that list. But still, at turn one I proposed peace to Makedonia with a pile of gold and they denied proposal as very demanding, on second turn they gladly accepted ceasefire and paid 1000x10 tribute. Why so sudden change? In my opinion they should be in war for some time at least and I dont see how they could get so much WarWeariness in starting turn or how they managed to switch stance. Same with Epeiros.

No idea what's going on with the agents or the changes, that's all z3n's realm.

There's something weird going on with diplomacy in turn 1 that we don't understand.

Hmmm, now I'm looking at the diplomacy-switch script, it has all kinds of problems. Rewriting it now, there are IF loops that should be inside other ones and some logical errors. The actual switch part needs to be in a monitor of it's own and consolidated thus:

Code: [View]

    monitor_event FactionTurnStart TrueCondition
        if I_EventCounter faction_turn_f_rome > 0                     ; it's the faction's turn
            if I_CompareCounter f_rome_PeaceSeeking > 0               ; the faction is in a peace-seeking stance
                generate_random_counter reset_f_rome_Weariness 1 12   ; the larger the range the lower the chance
                if I_EventCounter reset_f_rome_Weariness = 4          ; 1 in 12, ie 8% chance of occurring
                    set_counter f_rome_WarWeariness 0                 ; remove war-weariness
                    link_faction_ai f_rome warlike                    ; change to war-making behaviour
                    set_event_counter f_rome_PeaceSeeking 0           ; an event_counter to note the change in behaviour
                end_if
            end_if
            if I_CompareCounter f_rome_WarWeariness > 5               ; Faction is above war weariness threshold
                and I_CompareCounter f_rome_PeaceSeeking < 1          ; the faction is in a warlike stance - to stop this triggering every turn
                link_faction_ai f_rome diplomacy                      ; change to peace-seeking behaviour
                set_event_counter f_rome_PeaceSeeking 1               ; an event_counter to note the change in behaviour
            end_if
        end_if

Im glad to hear it. I replaced warlike code with diplomacy code in decr_campaign_ai_dm to see if they are negotiating in peaceful mode and factions are communicating again. If that switch will be fixed I hope endless AI wars will be over.

That's basically the difference between the two states. In diplomacy, they are reasonable and look to make peace. In warlike, it's standard Total War hates-everyone-war-to-the-death.

The above makes for a really passive game if everyone is in that state all the time, which is why we devised the notion of switching between them to make for a more organic experience.

Total war setting is very bad for AI as well. I have spent whole campaign in foreign territories and after first 150 turns, factions are stuck in a war on every border, with large armies tied for border defense and move remaining forces between fronts unable to do some significant move most of the time. They are also easy prey for the player when they cant focus forces.

Carthage is worst as it took them almost two years to move their offensive army fighting against Nabatu back home to defend against Numidians and after 6 turns they went back (and Numidia captured their capital before they have returned again). And they were at war with 4 other factions.

I'm very curious how it will go with new changes.

Would you like to test the new one?

Replace everything below the declarations with the above.

I thought you will never ask

I've only done the campaign-startup test - that will throw out silly things like having event_counters wrongly labelled as regular counters or non-existent factions. It doesn't crash the script, but I haven't tested any more than that.

1-10 turn Saka/Baktria Eperios/Rome+KH and some other factions have ended their starting wars, Ptolemaioi/Seleukea ended a war but they are fighting again. Factions still fighting have only one max 2 enemies. Getai and Seleucid diplomats are trying to bribe my settlement (I think)

25+ turn Saka/Baktria fighting again
Makedonia + Epeiros Alliance (Gods be merciful on us!!!)
Eperios + KH in peace again
Baktria Seleukea peace
First Punic war ended

30+ Hayastan war Sauromate
Areuakoi war with Leusitane but they make peace after one turn
Epeiros war with Rome
Nabateans attacked Seleukea
Makedonia/KH+Ptolemaioi peace

40+ Hayastan peace Sauromate
Areuakoi war with Leusitane but they make peace few turns later (I think this is scripted war after Leusitane captured Carpetania)
Ptolemaioi and Seleukea peace
Seleukea and Ptolemaioi armies crossed my territory on their way into Europe
Ptolemaioi asked me for money or they will attack, I paid and they left


It looks very interesting, but I'm not getting all info about politics for some reason. Sometimes I got a message about peace and I don't even know there was a war between them. It does also seem they shift their interests quickly. I will leave it to run some more to see an impact in long-term.

Also my reputation went to distrustful and I'm doing nothing only autoresolving battles with rebels in my territory (Pergamon)

Not so enamoured with the 1-turn wars - there are some war-triggers around the place and it sounds like the CAI is basically ignoring them when they happen.

To be honest, I have no idea how the notifications work.

As per another thread, there's a section that needs deleting from the descr_faction_standing.txt:

Code: [View]

; Adjust the AI relationships towards each faction based on difficulty level (AI factions have normal difficulty)
;------------------------------------------
Trigger 0092_Update_Easy_Difficulty
    WhenToTest FactionTurnStart

    Condition CampaignDifficulty = easy

    FactionStanding exclude_factions { } normalise 1.0 50

;------------------------------------------
Trigger 0093_Update_Normal_Difficulty
    WhenToTest FactionTurnStart

    Condition CampaignDifficulty = medium

    FactionStanding exclude_factions { } normalise -0.5 50

;------------------------------------------
Trigger 0094_Update_Hard_Difficulty
    WhenToTest FactionTurnStart

    Condition CampaignDifficulty = hard

    FactionStanding exclude_factions { } normalise -0.5 50

Trigger 0095_Update_Very_Hard_Difficulty
    WhenToTest FactionTurnStart

    Condition CampaignDifficulty = very_hard

    FactionStanding exclude_factions { } normalise -0.5 50

It shouldn't be there, and it's "normalising" relations towards negative over time. No idea if a change is savegame-compatible.

40+ Epeiros war KH

50+ Makedonia + Epeiros peace
I planned to make alliance with Ptolemaioi, but Seleukea asked me to attack them when I asked them for map. I asked Ptolemaioi for map too and they asked for 3600 bribe or they will attack so I paid.

60+ Gallatians are still asking me for money but Galatia belongs to Seleukea.
Carthage war Leusitane
Seleukea and Ptolemaioi failed to conquer Byzantion
Ptolemaioi invade Sicily
Factions are still trying to have max one enemy and they fight mostly with rebels

70+ Boioi war Lugiones
Pahlava war Seleukea


It is much stable now, but I guess it ìs because everyone is busy fighting with rebels.

I have repeatable crash after I auto_win fight with rebels through console (they besieged my only settlement and attacked). I will try to fight in manually later, but if I auto resolve it always happens

I've seen this before, but no idea what it means:
