  • Making the AI diplomatically aware.....

    Folks,

    Just so you know, even though I've been saying I can't be bothered fixing the AI, I'm looking into the one section as I see as needs work. Diplomacy, and it's prioritys. So last night I ran some experiments.

    1 - I changed the prioritys on sending and receiving certain diplomatic events (namely pacts and alliances).
    2 - I set the regard bonus amount for each turn at peace/pact/alliance a little higher.
    3 - I changed a couple of the response priorities as well.
    4 - I fiddled with roads to make them more 'attractive' bonus wise for the AI, and added roads to the lists of improvements to build for all categories (growth, production, etc).
    5 - As an expansion on diplomacy-war, I made the ATTACK and SIEGE goals almost irrisitable to the AI.

    Here's what happened. Remembering that at this point I'm working on extreme conditions and will narrow down to something balanced.

    Setup a mid-size planet with 8 civs on impossible. I cheated and gave each civ advance: cannons (and everything below it added in auto), 10000 PW and 20000 gold. I also gave each civ 4 settlers. Basically, I wanted it to be a bit further on than a beginning game. Myself as a player did nothing but build defense units (keeping 6 in my city at all times, disbanding excess). I didn't improve or anything. I quickly ran through 50 turns. Turning off FOW I saw:

    1 - The AI had spread all round the globe.
    2 - The AI had built roads EVERYWHERE! It had gone nuts with them. I even saw a roman city in the centre of 6 cities with double roads to each city. Even roads going to nowhere.
    3 - Units flowed down these roads comfortably. There was no congestion of stacks, no blockages or whatever. Just stacks moving comfortable to where they were going without hindrance.

    I took a look at the diplomacy of every civ. 3 civs were fighting an all-in war (with stacks of cannon/riflemen on the borders). But the interesting thing was that these three civs had built roads to this triple-border area and had connected. Therefore, battles were occuring between AI stacks. 2 civs had research pacts with each other, one of them having a normal pact with civ number 8 as well. Civ number 7 was on an island all by itself, and only had a couple of contacts, but couldn't do anything as it hadn't got diplos to them yet. I kept the turns rolling. I noticed:

    1 - The AI would declare war, fight an intesive battle with someone, then after a while when one sues for peace the war ends. The wars were short and bloody. I saw one civ send three stacks of 6-8 units at another civ at the one time. When peace reigned between two civs, the regard went up quickly till the next war (or sometimes turned into a pact).
    2 - During peace, the AI built roads like nuts for infrustructure. During war, it built roads near the frontier (reminding myself to add forts to the improve lists as well) thus making unit movement good.
    3 - The diplomats of the AI civs actually interacted. Admittedly it was usually an extreme (refuse a pact and they declared war) but it was something.

    Maybe there is life in there afterall. Will go back to moding tonight.

      I perked up when I read our interesting modifications. But please clarify - you said you changed this and that but in those documents and on those lines, what specifically did you enter as the new modifications?

        At this point as I mentioned I used extremes, so I wouldn't base my mods into a real game.

        But here's an example of what I did in diplomacy.txt

        The original:

        ProposalElement {
        Proposal PROPOSAL_TREATY_ALLIANCE
        SendPriority 100
        AcceptPriority 110
        RejectPriority 100
        SenderRegardResult 200
        ReceiverRegardResult 200
        ViolationRegardCost -100
        ViolationTrustCost -30
        }


        The moded:

        ProposalElement {
        Proposal PROPOSAL_TREATY_ALLIANCE
        SendPriority 200
        AcceptPriority 200
        RejectPriority 50
        SenderRegardResult 250
        ReceiverRegardResult 250
        ViolationRegardCost -300
        ViolationTrustCost -50
        }

        As I said, an extreme. But the increased priorities made the AI consider them. By increasing accept priority to the same, it makes the AI accept more alliance requests, as lowering reject makes it not want to reject it. The violation costs make the AI want to hold onto it a little longer. For example, with a -50 trust, by violating an alliance, the other party is going to take a LONG LONG time before it trusts the violator again. More in line to how I think.

        I'll try and fine-tune the diplo a bit more tonight and let you know tomorrow.

              Hmmm...... having trouble getting AI to build diplos. If I give him a diplo, he gets stuck in diplo. However on the plus side, I actually got this request from the Greeks:

              - They requested 200 gold in a haughty tone.
              - I refused.
              - They threatened war.
              - I still refused.
              - They declared war.

              After declaring war, they sent a couple of stacks at me, which I brushed off and they requested a cease-fire.

              This is the weekends goals:

              1 - Make the AI build diplos.
              2 - Make the AI pursue diplo functions as per their government (communist with other communist, repub with other repubs, etc) Birds of a feather flock together basically.
              3 - Make the AI pursue diplo functions based on their personality. Eg. Militarilist leaders pursue demands/threats. Scientists pursue advances/research pacts. Etc.

                I like the way people are approaching AI changes. Set goals then try to achieve them. I think we have a great opportunity to recreate CtP2 as a playable game.

                Keep the ideas flowing.

                  Dale - Your changes are encouraging. You might want to communicate what you are doing and what you've found with Wes as he is seeking input on what changes ot make to create a revised mod pack.

                    Have got the diplomacy mod happening well, intertwined with Blueo's frenzy mod (See general forum for teaser readme). It is however, the ai.slc I downloaded last friday, so the script may have errors. Since I don't have a website, who wants to host the zip file for me?

                        Ready for ddl on King Arthur's Court... I'll try the mod later tonight. But just from reading into some of the changes it looks really good... nice job Dale.

                          Am emailing version 2.1 of the mod to Rich this morning. Here's a short rundown of changes from 2.0:

                          - Name change to Diplomod 2.1.
                          - Made it generic, should work with any other mods, not just frenzy AI.
                          - Supports frenzy AI 1.02 (just a little change of the script is needed)
                          - Cleaner and meaner.

                            dale,
                            I'm glad someone is looking at the diplomatic aspects of the game. however, your mod makes the AI way too timid. Since the AI still insists on infringing on my borders with new cities, its been a tactic of mine to demand sale of these cities before they become too much of a nuisance. On occasion I hit the wrong button and no offer of payment is included in the demand. Today when i did this, instead of receiving a rejection, the AI accepted. In fact, i realized that they accept EVERYTHING. So, I demanded their largest city with no payment. They happily agreed, at which point I demanded every city of every civ I had contact with. I now control 1/2 the world without firing a shot or paying a dollar. Before that, I was getting offers to exchange maps every 4 or 5 turns. I'm looking forward to more realistic diplomacy, can this be fixed without undoing everything?

                              Thanks for the feedback Alpha Wolf. I'll look into it.

                              Edit: I've found the problem. I used a "Consider" statement when I should've used a "Change" statement. Will fix for version 2.3
