Aquiring Unique Units?

[Edgecrusher]

Since my knowlege of Python/SDK is pretty limited and I imagine what I want to acomplish would have to be done via one of these options, I pose a question to those more experienced than me.

Would it be possible, during the coarse of a game for a Civilization to aquire the ability to build a Unique Unit, say after a given wonder was built?

For example:
In the past, I had a wonder called "The Crusades", the builder gaining the option to build a new unit called "Crusader" which I gave a strength of 7, and a bonus to city raiding, sort of an upgraded Swordsman for the middle ages, the Crusader also had the ability to build roads and forts. This was fine, but it limited the construction of the unit to the city if was built in.

What I want to acomplish is, say a civilization that starts in the Tundra/Ice regions of the world. Over time they would "adapt" to their harsh climate, and learn to servive.
I would like to create a wonder that can only be built above say latitude 20 or so, and upon completion grants the builder construction of a unit, nationwide. Potentially this new unit would replace an existing unit: For example this Wonder grands the builder construction of an "Inuit Worker" or something to that effect, which replaces the regular worker, but has access to build 1 or 2 improvments on the Tundra/Ice, that a normal worker wouldn't have the ability to do.
I dont know if this would cause an issue for civilizations that already have a unique unit that replaces it (India)

I know that I may not be explaining it right, I was just curious if something to that effect could be achieved, via Python or the SDK

My Dynamic Unique Units Mod does precisely this... it allows the acquisition of unique units through techs, buildings, and events... I'm also considering expanding this for Civics and Religions. The mod is not updated to BtS 3.13, but I've compiled a new 3.13 DLL and I just have to test and make sure it works, so look for that update some time this week.

awesome, originally I was thinking about climate based units, in addition to some religious based.

Well, the best way to do it based on climate is this: based on the criteria of your choosing, give a new technology (or the opportunity to research a new technology) that will unlock a particular unit. Currently, my code does not allow for the overwriting of UU's. I might add in an XML-defined value to permit this however.

Of course, if the end goal is to add new improvements buildable only by those civilizations, there's ways to do this without giving those civs new UU's. You could make those improvements have a prereq tech that's only given to civs that occupy cold climates for example.
