098 teaser: NEW AI and DIPLOMACY

[Macaras]

Hi guys, I just want to share that I am working on the campaign AI and diplomacy for the new version.

Here is the last version of AI: https://www.mediafire.com/file/v64ke...-2022.zip/file

The AI is based on PiterAI with some diplomacy and faction relations modifications, especially regarding dealing with human. The way AI factions wage war and make alliances with each other is basically unaltered PiterAI. It is still work in progress, but here, in short, is what you can expect:

1. AI will attack adjusting the size of the army, many times using invade opportunistic. It is more focused on defense though, and many times will be using full stacks for both defense and attack:

2. Diplomacy is balanced - sometimes AI will be very reliable or even trustworthy:

3. It is also much more difficult to make alliance, ceasefire and buy or exchange settlements (more realistic):

3. Naval invasions happens when ai faction is strong enough:

There are also many other minor changes.

BELOW IS THE DIPLOMACY GUIDE:

Spoiler Alert, click show to read: 

1. Reputation and relations go from -1.0 to +1.0. Lowest to highest:
Reputation:
Despicable -1
Deceitful -0.8
Very untrustworthy -0.6
Untrustworthy -0.4
Dubious -0.2
Mixed = 0.0
Reliable 0.2
Very Reliable 0.4
Trustworthy 0.6
Very Trustworthy 0.8
Immaculate 1
Relations:
Abysmal -1
Terrible -0.8
Very poor -0.6
Poor -0.4
So-so -0.2
Reasonable =0.0
Amiable 0.2
Good 0.4
Very Good 0.6
Outstanding 0.8
Perfect 1

1. High reputation will give some benefits:
- Trusted ally- if rep is higher than reliable (precisely 0.3) your allies will not attack you,
- Better relations with others, smaller chance of being attacked,
- New trades and alliances and even buying settlements are easier,

3. To raise reputation:
- Release prisoners (also improves relations with your enemy)
- Assist your allies in battle,
- Take part in crusades, jihads and conquer the targets
- Build big cathedrals and mosques, and big charity centers,
- Never exterminate or sack cities, be very careful to start the war first.

4. If you are at war and relations fall to terrible or abysmal your enemy may not want peace no matter what. Just stay in your territory, release prisoners if he attacks you, wait until he forgets a little bit the harm done and when relations go up, try ceasefire again. Being at war is sometimes beneficial as winning battles and releasing many captives gives good reputation the fastest.
5. When you are among one of the 5 or even more one of 3 biggest factions, the relations will gradually decrease to very bad, and that should result in a war from many directions. If your reputation is very good, it will not happen or will happen later (remember that some factions start already being one of the biggest)
6. Buying or trading settlements is very rare, if another faction has only few settlements probably there is no reasonable price that will make them sell it.
7. Beware of being called warmonger as it will decrease rapidly your relations and public order in your cities.
8. Giving money as a gift will help your relations very little and not affect your reputation at all (neither + nor -). Usually, the amount to pay for increase in relations is too big to make it worth it. Alliances are also much more expensive than before or in vanilla.
9. Many times, especially in beginning, you will need to wait for the other factions to propose the alliance or ceasefire- you will basically have not enough money to pay for it. It’s on purpose, otherwise the whole diplomacy in the game is reduced to have a lot of money. There are only 5 cases when the AI will want peace (even sometimes to the point of paying a lot for it):
- randomly (so if you want peace, send diplomats every turn)
- when much weaker than human (three entries with very specific conditions- military balance, free strength balance, frontline balance and especially number of enemies counts)
- has a ceasefire mission from the Pope (only between catholic factions, even if AI is winning and is very stronger, sometimes the player may not be conscious of being helped by the Pope)
If you enemy doesn’t want peace, you are the one that needs to pay for it. After signing a treaty, there is a time when no attack will occur (10 turns after ceasefire and 20 turns after alliance).

10. As alliances are more expensive and the diplomacy more precarious- choose your allies well. The world will soon be divided into different groups of allies. If you rep is good enough to be treated as a trusted ally you will benefit from your allies helping you in war. To survive as Portugal, Hungary, Serbia and some other factions depends on having trusted allies and keeping some borders protected. Most of the times it is extremely difficult or impossible to wage war with few enemies at the same time.
11. The difficulty raises with time. In the beginning the player have a little easier time to prepare for war. After turn 50 AI becomes more aggressive, after turn 100 your allies will be more backstabbing (if you are not considered a ‘trusted ally’).

There are other factors in diplomacy, but not so important as the ones above. The ones I wrote above are tested to be working and trigger but still needs improvement. Following your feedback, I will continue working on it and raise/ lower some factors to make it work better.

Very interesting changes. Great job!

[alhoon]

Very good!

[nvm]

Wait, you actually got the game to show the exact modifiers to diplomacy? That is very impressive, how exactly did you do that?

[Macaras]

There is a command that works in the scripts : console_command toggle_demeanour. I put it together with two other commands that we use to see some details of the game:

;========================================================================================
;------- Reveal everything ( shift + r to trigger)
;========================================================================================


monitor_event ShortcutTriggered ShortcutTriggered strat_ui revealShortcut
log --- REVEAL SHORTCUT FIRED
console_command toggle_fow
console_command toggle_perfect_spy
console_command toggle_demeanour
end_monitor

Perfect spy is like a toggle_fow but allows to see also the armies, its basically "perfect spy" everywhere With this script after pressing shift + r you will also see the demeanor in the diplomacy window.

I've played with Pieter AI before and I found the game to not be enjoyable as I was attacked constantly by almost everyone after a certain point. I like a challenging game, but I was being attacked everywhere with small armies by all my former allies. It was one small battle after another after another every turn.

Perhaps one solution might be if you could make a second version of the Pieter AI with a very low backstabbing where alliances usually hold quite strongly. Anyway, just a thought. Looking forward to your new version of Pieter AI!

[Macaras]

It happens that a small army attack another small army but as much as I observed ai always obeys the factor 0.95 set in the descr_campaign, which mean ai will only attack if his army is 95% of the enemy's army or bigger. I totally agree with your observation on being backstabbed, in the last version I lowered it. If you are very reliable and relations are more or less, above terrible your allies will never attack you, unless you become very strong, there is 'tall poppy' syndrome- they see you as a threat, then the relations will go down to abysmal and you will be attacked. Here is the last update, if you want to try it:

https://www.mediafire.com/file/jz2mt...-2022.zip/file

[Kilgore Trout]

Thanks for your reply, but I won't be able to play for quite awhile as I'm very busy with work now. Very much looking forward to it though when I get the time!

think i remember reading somewhere that version 0.98 altered diplomacy so that even while having immaculate reputation youll still lose relations with other empires if youre to large is there a way to revert that so its just reputation based if so could someone please share what files i would need to edit thank you

Hi Mekal, its in the file .../SSHIP_098/data/descr_faction_standing.txt :

;------------------------------------------
;Standing rapidly decrease when human becomes strong
;Gets to 50% strongest and in first 5 factions
;Reputation reliable and above prevents

There are also three more entries above that affect also AI. If you want to switch them off, you may just put a sign ';' in the beginning of the line "FactionStanding exclude_factions { slave, .....".
One observation - if your reputation is above 0.4 or even better 0.6 - you will not be punished by these entries. If you are very reliable and up - trustworthy, very trustworthy, immaculate reputation you will also very unlikely be attacked by your allies, ceasefires will be easier and everybody will like you more. To have this reputation:
-release prisoners (especially above 100 captives),
-take part in the crusades, jihads,
-construct cathedrals and temples,
-never exterminate or sack settlements - never attack an ally, very rarely start wars.

thank you so much establishing solid borders then switching to playing tall is going to be much more enjoyable now

apologies i couldnt find the edit button i was still slowly losing reputation with every other empire on the map with very trustworthy reputation even while being at peace i may have misunderstood though either way hopefully this changes that and thank you again

[Macaras]

Maybe the problem is the warmonger part which lowers reputation but its corresponding part in cs.txt was not working properly. So you may comment the lines that start with "FactionStanding global normalise..." it will make these entries doing nothing.

    Condition I_EventCounter player_aggressivity > 8

Is the AI that comes in the April 98 download the most up to date version?

Also, any ideas what new things will be in the next patch or update, and when that might come?

Thanks!

Thanks!

very soon! we're just putting together a new version.
and the Macaras' AI/diplomacy will be there

[Kilgore Trout]

Well, then I might just wait until it comes out before I start my new campaign.

Also, btw, I was wrong in requesting the Germanicu5 ReallyBadAI Hardcore Addon be included in SSHIP. I played a custom battle with .98 and it appeared that the the Addon is already included. So that is a wonderful thing!

Thanks Jurand! Looking forward to the next edition or update!

This is a first attempt to make some diplomacy guide which seems to be very important to know what’s going on during the campaign. I hope it will be helpful:

1. Reputation and relations go from -1.0 to +1.0. Lowest to highest:
* Despicable
* Deceitful
* Very Untrustworthy
* Untrustworthy
* Dubious
* Mixed
* Reliable
* Very Reliable
* Trustworthy
* Very trustworthy
* Immaculate

1. High reputation will give some benefits:
- trusted ally- if rep is higher then reliable your allies will not attack you,
- Better relations with others, smaller chance of being attacked
- New trades and alliances and even buying settlements are easier
3. To raise reputation:
- release prisoners(also improves relations with your enemy)
- Assist your allies in battle,
- Take part in crusades, jihads and conquer the targets
- Build big cathedrals and mosques, and big charity centers,
- Never exterminate or sack cities, be very careful to start the war first.
4. If you are at war and relations fall to terrible or abysmal your enemy may not want peace no matter what. Just stay in you territory, release prisoners if he attacks you, wait until he forgets a little bit the harm done and when relations go up, try ceasefire again. Being at war is sometimes beneficial as winning battles and releasing many captives gives good reputation the fastest.

If your reputation is very good, it will not happen or will happen later (remember that some factions start already being one of the biggest)
6. Buying or trading settlements is very rare, if another faction has only few settlements probably there is no reasonable price that will make them sell it.

8. Giving money as a gift will help your relations very little and not affect your reputation at all. Usually the amount to pay for increase in relations is so big that make it not worth it. Alliances are also much more expensive then before or in vanilla.

I find the AI/diplomacy punishes the player too much. I'm convinced it's impossible to win with some factions such as Rum on harder difficulty where releasing Romans is not viable and you also need the additional income from ransoming. AI aggression is fine but imo the diplomacy debuffs for certain actions need a bit of a nerf.

[Macaras]

I think that the next version will be a little toned down and polished in this sense, regarding warmongering and some other aspects. Its coming soon
