It seems as if you can add unique unit names by making a string list inside the XML. I've never tried, but I guess it would be like this:
Code:
<UniqueNames>
<UniqueName>TXT_KEY_GREAT_PERSON_MOSES</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_MAHAVIRA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ZOROASTER</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ANANDA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_CHUANG_TZU</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_MENCIUS</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_MO_TZU</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_JOHN</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_PETER</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_PAUL</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_RABBI_AKIVA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_MANI</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_AUGUSTINE</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_PATRICK</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ABU_BAKR</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_SHANKARA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_KOBO_DAISHI</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ATISHA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_ST_THOMAS_AQUINAS</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_MOHAMMED_SHAH</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_TSONGKHAPA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_JEANNE_ARC</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_NARAK</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_TIPU_SULTAN</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_RAMAKRISHNA</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_NARAYANA_GURU</UniqueName>
<UniqueName>TXT_KEY_GREAT_PERSON_SOJOURNER_TRUTH</UniqueName>
</UniqueNames>
Just before the code you put from the CvUnit::init() method, the unit's name is set to their default. "Great Prophet", for example. I believe this would be done in CvUnit::reset().
Then, it does the code you're referring to:
Code:
if (GC.getGameINLINE().getUnitCreatedCount(getUnitType()) < GC.getUnitInfo(getUnitType()).getNumUnitNames())
What this does is check how many total units of that type of been created, and compares it to how many unique names it has. For example, if 20 great prophets have been created and there are 30 unique names for great prophets, then this function will pass.
Code:
iUnitName = GC.getGameINLINE().getUnitCreatedCount(getUnitType());
This code will get the number of units created. The first time a prophet is spawned, there are zero prophets that have been created, so it gets name number 0 (moses). The game object (which is retrieved using getGameINLINE() ) has a counter that keeps track of how many units of a certain type have been created. When the unit's created, that counter is incremented. So, the second time a great prophet spawns, the counter will be at 1, and the 1th name is used (mahavira).
Code:
iUnitName *= max(0, (GC.getWorldInfo(GC.getMapINLINE().getWorldSize()).getUnitNameModifier() + 100));
iUnitName /= 100;
This part makes it a bit tricky. The iUnitName is multiplied by a number. The getUnitName modifier by default ranges from 50 to 0. Here are some values:
iUnitName before this code -> iUnitName after this code
At getUnitNameModifier() == 50 (WORLDSIZE_DUEL)
0 -> 0
1 -> 1
2 -> 3
3 -> 4
4 -> 6
5 -> 7
At getUnitNameModifier() == 20 (WORLDSIZE_STANDARD)
0 -> 0
1 -> 1
2 -> 2
3 -> 3
4 -> 4
5 -> 6
At getUnitNameModifier() == 0 (WORLDSIZE_HUGE)
0 -> 0
1 -> 1
2 -> 2
etc.
What is the point of doing this? My best guess is that Firaxis found that in larger games, more units can be developed. Thus, by placing the unit names in historical order, you have a better chance of drawing the name of a figure that is somewhat at the same time as the game if you have games with less prophets being made "skip" a few names.
Finally, it does one last check:
Code:
if (iUnitName < GC.getUnitInfo(getUnitType()).getNumUnitNames())
{
setName(gDLL->getText(GC.getUnitInfo(getUnitType()).getUnitNames(iUnitName)));
}
If the new iUnitName that it generated is past the list of total unit names, then no unique name will be given. Thus, if the name to be used is 50 and there are only 30 names, it doesn't assign it a new name. If there is a unique name for it, then the unit's name is set to that unique name.
So, that's what the code does in a nutshell. I'm willing to bet that, because the unique names can be put into the XML, you can probably make them use a random name rather than the above algorithm for generating a name by changing the onUnitCreated function in CvEventManager.py. Just get a random number between 0 and gc.getUnitInfo(eUnitType).getNumUnitNames(). Then, set the unit's name using:
Code:
pUnit.setName(gc.getUnitInfo(eUnitType).getUnitNames(iRandomNum)
Oh... well that explains why i couldn't find it. Thanks 
It's not as simple as i thought it would be... is it possible to get an explination (mostly for the functions)?
Gerikes.
