So, province mapping is still holding us up? I'll try and get some extra swathes mapped this week. Once again, I don't know how neat it will be (I do my best), but at least we can start testing once the province mappings are done.
Central Europe mapped. The near east is all that's left.
A note on technologies: unless I've missed something important, CK2 tech can have levels 0 - 5 (province based). Assuming we know which CK2 tech belongs to which EU3 techtype, do we
1) Average the tech across all provinces in the new nation, or
2) Take the highest as the new tech level?
Also (have we discussed this yet?) how do we determine tech group? Simply using religion doesn't seem right. Simply using geographical location doesn't seem right... Are their science related events, flags, or decisions that we can use? Should everyone just be western?
EDIT: I've sussed it.
For starters, your EU3 tech group (as a mechanic) defines
how quickly you research tech. To convert for this mechanic, we need to find something equivalent in CK2. It does exist, in the form of Monastic Schools (Bishoprics) and Universities (Cities). Each of them increases your technology rate by some percentage.
This rate is province-by-province. To determine the average learning ability of the country, therefore, we must add up the total number of schools and universities (by percentage point, perhaps) and then divide that value by the number of provinces in the country.
We should now have each country with a "learning ability" score. All we need to do is sort this in to tiers. This is a tricky part. We need to be sure that the correct tech group gets added for the right reasons. For example, is a complete lack of universities the same as having new-world tech ability? Maybe. Also, can steppe countries in CK2 build universities? That would be very interesting indeed.
Anyway, assuming that we say that no learning insitutions = new world tech (that is, complete inability to learn) then we say that new world tech = 0 learning score. The best western tech is the highest learning score. Take the value of the highest learning score, and split it in to tiers, such that:
0 - 10% = New World
10 - 20% = Sub-saharan
20 - 40% = Chinese
40 - 50% = Indian
50 - 80% = Muslim
80 - 85% = Ottoman
85 - 90% = Eastern
90 - 100% = Western.
Wherever the realms "learning ability" score falls determines the tech group that they will be in at game start. For example, if the highest learning ability was 100, and my country scored 86, then my tech group would be "Eastern", and whoever had the 100 score would be western.
This method ensures a couple of things:
1) There will always be at least one western nation (for westernisation to begin).
2) The further away from zero the worlds average learning ability score is, the more western (and less new world) the world becomes.
For example, if I had 5 nations, with scores like:
England: 0
France: 1
Germany: 2
Spain: 3
Russia: 4
... the tiers would be:
0 - 0.4 = New World
0.4 - 0.8 = Sub Saharan
0.8 - 1.6 = Chinese
1.6 - 2 = Indian
2 - 3.2 = Muslim
3.2 - 3.4 = Ottoman
3.4 - 3.6 = Eastern
3.6 - 4 = Western
And therefore
England = New World
France = Chinese
Germany = Muslim
Spain = Muslim
Russia = Western.
However, if there scores are like:
England = 96
France = 96
Germany = 97
Spain = 98
Russia = 100
Then the western cutoff would be 90, and therefore they would all be western.
This should allow us to convert the learning ability of the CK2 realm in to a tech group in EU3.
The total tech growth modifier for each building (and level) can be read in \common\buildings.txt. Search for ct_university, and tp_school.
So, with tech groups dealt with, we can move on to the techs themselves. CK2 tech is split in to three broad categories with many individual techs (but no naval techs). Since there are no navy techs, I believe that both the army and navy tech level should be determined by the military tech of the CK2 realm (since basing only navy tech on, say, port province numbers would be a bit arbitrary), or navy should simply be based on those military techs that aren't completely land-bound.
All we need to do is determine which CK2 techs belong to which EU3 techs, we average them (or pick the highest ??? ) in the realm, and that will be the new tech level for the country. Some of the CK2 techs may appear in multiple EU3 techs
Government:
Church Taxes
Noble Customs
Popular Customs
Religious Customs
Majesty
Spiritual Art
Cultural Flexibility
Religious Flexibility
Legalism
Production:
Farming
Town Infrastructure
Church Infrastructure
Construction
Trade:
Army:
Bows
Light Armour
Heavy Armour
Infantry Melee Weapons
Cavalry Melee Weapons
Siege Equipment
Military Fortifications
Tactics
Navy:
Bows
Light Armour
Heavy Armour
Infantry Melee Weapons
Siege Equipment
Tactics
So, we have:
1) Determined tech
group by the actual learning ability of the CK2 realm.
2) Determined tech
level by using the CK2 tech level.
