AI Leaders Personality Matrix

These are three Excel spreadsheets of the BtS 3.13, Warlords V2.08 and Vanilla V1.61 CIV4LeaderheadInfos.xml files. In these versions all tags are annotated

The BtS version was compiled by karlkrlarsson
The Warlords version was compiled and annotated by ori
The Vanilla version was compiled by NeverMind and annotated by PeteT

The File can be found in the DownloadDataBase.

Please also note fengertao's Vanilla version of this spreadsheet.

 

Good work, ori! I would like you to add my vanilla spreadsheet in your file, in order to keep this info in one place.

 

Thanks, I'll upload a combined version once I return home after Thanksgiving...

 

Here's a link to another commented version of Nevermind's spreadsheet:

I just uploaded the combined file using PeteT's annotated version of NeverMind's spreadsheet

AI Attitude explained:

The AI attitude towards another player (be it human or AI) is defined as follows:
if no other sources are quoted then the calculations are from CvPlayerAI.cpp and the Leader specific values are from CIV4LeaderHeadInfos.xml

Friendly:
iAttitudeVal >= +10

Pleased:
iAttitudeVal >= +3

Cautious:
if no other Attitude rule is fulfilled

Annoyed:
iAttitudeVal <= -3

Furious:
iAttitudeVal <= -10


The following terms are used:

US (the active AI)
THEM (the opponent towards whom the attitude is calculated)

iAttitudeVal = +100 if US and THEM are on the same team (i.e. Team play or Permanent Alliance)
iAttitudeVal = -100 if THEM is Barbarian

In all other cases iAttitudeVal is calculated using the following items:

&#8222;not visible&#8220; denotes Items not displayed ingame

Item 1 (not visible):
US iBaseAttitude

Item 2 (not visible):
THEM iAttitudeChange (source: CIV4HandicapInfo.xml - = +2 on Settler, +1 on Warlord, 0 on Chieftain, -1 on Noble and above)

Item 3 (not visible):
If AggressiveAI option is ON and THEM is Human:
-2

Item 4 (not visible):
If THEM is NOT Human:
+(4 &#8211; abs(US Peace Weight &#8211; THEM PeaceWeight))
abs means that the result of (US Peace Weight &#8211; THEM PeaceWeight) is always a positive value
PeaceWeight = iBasePeaceWeight + (0 to iPeaceWeightRand) as shown by Seven05

Item 5 (not visible):
If THEM is NOT Human:
+ the lower of US iWarmongerRespect or THEM iWarmongerRespect

Item 6 (not visible):
- the higher of 0 or (THEM number of Team members &#8211; US number of Team members)

Item 7 (not visible):
if THEM is higher ranking:
+(RankDifference*iWorseRankDifferenceAttitudeChange/(NumberOfPlayersEverAlive+1)) Note: these modifiers are negative in the .xml - so this produces a negative modifier...

Item 8 (not visible):
if THEM is lower ranking:
+(RankDifference*iBetterRankDifferenceAttitudeChange/(NumberOfPlayersEverAlive+1))

Item 9 (not visible):
if US rank >= NumberOfPlayersEverAlive/2 AND THEM rank >= NumberOfPlayersEverAlive/2
+1

Item 10 (not visible):
if THEM WarSuccess > US WarSuccess:
+iLostWarAttitudeChange
WarSuccess seems to be the number of Units killed (according to CvUnit.cpp)

Item 11 (visible):
CloseBordersAttitude

Item 12 (visible):
WarAttitude

Item 13 (visible):
PeaceAttitude

Item 14 (visible):
SameReligionAttitude

Item 15 (visible):
DifferentReligionAttitude

Item 16 (visible):
BonusTradeAttitude

Item 17 (visible):
OpenBordersAttitude

Item 18 (visible):
DefensivePactAttitude

Item 19 (visible):
RivalDefensivePactAttitude

Item 20 (visible):
ShareWarAttitude

Item 21 (visible):
FavoriteCivicAttitude

Item 22 (visible):
TradeAttitude

Item 23 (visible):
RivalTradeAttitude

Item 24 (visible):
MemoryAttitude (i.e. Accepted or Rejected Demand)

Item 25 (visible):
AttitudeExtra (only if specified for a Scenario &#8211; not in Core Game)

All Items are added and the total Attitude is returned.

 

Note that:

Item 4 means that Leaders with a similiar Peace Weight have a positive modifier of up to +4 and Leaders with very different Peace Weights have a very high negative modifier (up to -9)

Item 5 means that Warmongers have a positive modifier with each other...

Edit: for Diplomacy Victory any AI will vote for the Player on whose team it is, if there is none it will vote for the Player towards whom it has the higher attitude if this attitude is higher than +7. If both Players are tied it will abstain, if the attitude towards both is +7 or below it will abstain.

 

Ori, Thanks for the explanation re attitudes, I had tried and struggled to understand what was going on then found thid thread and it became clear



Thanks

Ralph

 

actually I found one thing that is not quite right here (I corrected it in the Attitude thread but not here):

rank: is 0 for the HIGHEST scoring civ, i.e. the player with the highest rank number is the one with the lowest score. This means that iWorseRankAttitude applies when the AI has a lower score and iBetterRankAttitude applies when the AI has a higher score. Also item 9 thus applies if both players are in the lower half of the score table...

 

Don't worry with the signposting in this thread I had puzzled that bit out myself!!

Ralph

 

For when a BtS update ,ori ?

 

Done






Actually karlkrlarsson did it 5 months ago but I promised to add it to this file by the weekend - never specified which one though

 

I already noticed that ( a small delay ) .... Thanks

 

Ori, do you know if they changed anything for 1.74 Vanilla? Like the rounding bug in iBetterRankAttitudeChange that causes a value of 1 to be useless? Or is it the same as 1.61?

Also, I can't find where it says how long a leader "Refuse to talk" to you after you agree to stop trading with him?

Thanks,
TDK

 

I don't know by heart but will check - tough I am away from my civ computer for the next two weeks (hope I don't go cold turkey ) so it will be a while before I reply to this - If I don't prod me
I think there where no or no remarkable changes in 1.74/2.13 though I will recheck this as well

 

I forgot about this - sorry:
there are no xml changes between 1.61 and 1.74 and none between 2.08 and 2.13.
I cannot find any changes for the BetterRank thing and for the time it takes for the AI to respond again I am unsure - I don't really follow that code too well, it confuses me I'll try to understand it better and report again.

There are no changes for this file for the BtS 3.17 patch.

 

Could we have some explanation on how to interpret the numbers?

Say right now I want to make Alexander go to war with another AI. I go to your spreadsheet for BtS and see that for Alexander, CONTACT_JOIN_WAR as a value of 20. How do I use this number to know how many diplomatic points I need in my current game to open this possibility to me?

It would be great if someone had the time to post how this spreadsheet can be used in a few different cases (a kind of tutorial or article with examples).

 

look here: http://forums.civfanatics.com/showthread.php?t=350385
for the two thresholds that govern war trade

 

Thanks, it cleared that specific problem up.

The numbers in the matrix are affected by the difficulty level, right? Is this documented somewhere?
