I've thought up another idea that may be of benefit to scenario makers... its implementation require no additional graphics, just adding to the unit and building XML files, as far as I know...
As a scenario maker, I often wish I could get the barbarians to produce some of the nifty units that are associated with the many Civs included in the mod. For instance, if I have Barbarians in the land now known as Scotland, I wish they'd produce highlanders. In the same scenario, however, I want my Barbarian cities in Saxony to produce Fyrdman units.
I've though of how this might be done without using up a Civ slot (of the 19 possible) for individual barbarian civilizations.
Here is how it could be done...
First, a building must be created for each potential barbarian civilization... call it a Cultural Centre. So there would be a Scottish Cultural Centre, a Saxon Cultural Centre, and so forth. This building would be unbuildable, even by barbarians (I'm certain there are ways to do this). It would only be placed by scenario makers in cities that would have that culture. So Inverness, for instance, would have a Scottish Cultural Centre placed in it by a scenario maker, while Bremen might have a Saxon Cultural Centre. No graphic would be necessary.
Next, an alternate unit would have to be created for each UU (excepting ships as I don't believe they are produced in cities). For instance, a Barbarian Highlander would be created, and a Barbarian Fyrdman would be created. They would use the same graphics as the usual UUs. I'd remove resource requirements, though. And possibily even tech requirements. These would be Barbarian UU's replacing the normal units.
Finally, I would make each Barbarian UU require the proper Cultural Centre in a city to be built. For instance, the Barbarian Highlander would require a Scottish Cultural Centre, while the Barbarian Fyrdman would need the Saxon Cultural Centre.
What ought to happen then, is that when a Barbarian city is set to produce a swordsman, if there were no Cultural Centre, it would go ahead and produce one, however, if there were a Cultural Centre, and the Barbarian UU for that Cultural Centre were a swordsman type, then that UU rather than the swordsman, would be produced.
And that is how my Barbarians would produce Highlanders in Scotland.
Some thoughts...
-Civs with just ship UUs would not need this to be done.
-Cultural Centres could be made capturable, in which case, the units may be producable by the capturing Civ. I don't like this idea, but it is doable, I believe. Generally, I think that Cultural Centres should be destroyed on capture of the city.
So, any thoughts? Worthwhile to do, or just window-dressing?
