I have been tweaking each empire AI for my mod (Fair Fight) and i am wondering what these modifiers do exactly : ValueCoef, TrendCoef, ValueRangeCoef and TrendRangeCoef. From what i understand they influence how certain aspects of diplomacy affect them, but i want to know what is the difference between them. In most cases the devs seem to put each values the same, though a few instances they have varying values. I want the AI to be more challenging and less identical personality wise so i find this important.

Somewhere buried deep in these forums one of the Devs explained them, cause I had asked roughly the same.



I guess you are in Personalities.xml.



All those "Coef"s are simply multipliers for the variables in DiplomaticAttitudeModifier.xml



Value = This is added or substracted to the attitude right when something occures.

Trend = This is added or substracted per turn to the attitude as long as the reason persists and the ValueRange is not exceeded

ValueRange = This determines the Min/Max-Value for a modifier, it covers being reached by via Trend and also when some things can occur several times. For example: Common enemies, you get the Value for each enemy but it won't exceed the Value Range

TrendRange = In some cases the Trend is computed somehow (for example for the case of score-difference) In these cases this acts as a limiter for the trend.

Thanks, now i know what i will do with those.
