ck2toeu4's Issues

Check religions

CK2 has a higher religion variety than EU4. Some of them may be worth keeping around.

PAP/FAP primary culture

Confirm PAP/FAP get their ideas correctly regardless of ruler culture, same as primary culture.

Carpathian-Russian culture

Need a culture for trans-Carpathian russians.

(Reminder) Diplomacy creation

Holy Roman Emperor
Sets the current Holy Roman Emperor

<year>.<month>.<day> = {
    emperor = <tag>
}
Celestial Emperor
Sets the current Celestial Emperor

<year>.<month>.<day> = {
    celestial_emperor = <tag>
}
Relations
All relations follow this format:

<type> = {
    first = <tag>       # The overlord, if the relation is a overlord-subject relation
    second = <tag>      # The subject, if the relation is a overlord-subject relation
    start_date = <date> # When to start applying the relationship
    end_date = <date>   # When to stop applying the relationship
}
These are the following valid relations:

alliance
royal_marriage
guarantee
warning
vassal
march
union
Dependency
For custom subject types, you can use the dependency effect, which allows to specify subject_type:

dependency = {
    subject_type = "<subject type>"
    first = <tag>       # The overlord, if the relation is a overlord-subject relation
    second = <tag>      # The subject, if the relation is a overlord-subject relation
    start_date = <date> # When to start applying the relationship
    end_date = <date>   # When to stop applying the relationship
}

religious_school

We have to devise how to determine Islamic religious schools

Frisian and Friesland

Not East Frisian cores but Friesland cores.

Break out of elective monarchy decision

Add a decision available to those with elective monarchy reform to break out of it at ADM 10 for -2 stab. AI = 0, player choice.

Papal States vs Papacy.

Correct this by dropping papal states everywhere and replacing every pope mention with papacy.
If pope holds no land, PAP should not exist.

accepted Cultures same as Primary cultures

Converter adds accepted culture lines for countries without a second culture, adding an accepted culture for its primary culture, such as north France having primary culture of cosmopolitan French, and accepting culture of cosmopolitan french, affecting about more than half the countries from the converter. Pls add a toggle for accepted culture or fix the feature ty.

Regnal numbers

Currently rulers are output without regnal numbers.

Configurable dev weights

make a file with:
devFromBuilding = 0.1
devFromBarony = 0.3
and use that.

See what's wrong with counter-reformation:

On China

CK2 has different Chinas, according to the Emperor's dynasty. If possible, every out-of-CK2-map owned by Ming and the subsequent celestial emperor history file should be updated with whoever is the Emperor of China.

A mapping of tags could be used.

Probably unintended double quote in Cilician culture's germ loc

CK2ToEU4/CK2ToEU4/Data_Files/blankMod/output/localisation/replace/converted_cultures_l_german.yml

Line 128 in 7c26292

cilician: ""Cilicische"

Support for Tianxia

(Self-assigned) As the CK3->EU4 is getting support for their own Asian mod, I'm thinking we could have support for CK2's Asia mod, Tianxia.

Third option for siberian wipe - all, regardless of size.

National Cores

See what cultures have a defined primary and if we have dead nations of that primary. If so, distribute dead nation cores in provinces where they have culture.

On the HRE

Currently, nothing is done besides splitting the Empire.

All provinces held by the Empire should get the line hre = yes inside.
All the history files of the Electors should get the line elector = yes inside.
history/diplomacy/hre.txt should have this line as content: 500.1.1 = { emperor = [Emperor's Tag] }

How to determine the Electors?
Search among the generated vassals of the HRE (and the Emperor himself).
Find the three theocracies whose rulers hold the highest piety and add them as electors.
Then find the four non-theocracies whose rulers hold the highest amount of prestige and add them as electors.

Gold conversion

Through add_treasury

Take CK2 wealth (gold) and divide by 2.27948793172 (assuming CK2 gold is measured in pennyweights and using the Venetian florin)

estate privileges?

Tajik culture

Also, the Persians in Afghanistan should become Tajiks

Option for vassal splitoff

• ie, disable through config.

Splitting cultures

(A reminder for me)
German, French, Italian, Spanish, Latin-Roman, Jewish need to be split accordingly.

Peasent republics for peasent leaders

See if a peasent revolt leader holds an indep title and swap that tag into a peasent republic. Do not do that for protected tags (ROM, BYZ, PAP, HRE etc)

Config: HRE dynamics appointee

Manually set which empire inherits HRE dynamics on conversion through config options. Default to e_hre.

Eliminate global configuration instance

The existing extern Configuration theConfiguration; was a patch to work around removing the Configuration class's singleton status. It causes a lot of shared state issues, particularly with tests.

Make sure to delete the actual instance (at the top of the cpp file) while you're at it.

(Reminder) Advisor creation

advisor = {
    advisor_id = <id>           # The advisor's unique id

    culture = <culture>         # The advisor's culture
    religion = <religion>       # The advisor's religion
}

Council conversion

Councillors may be converted into advisors.

define_advisor will be used.

Province tax, production and manpower

Where should we have them from?

(Reminder) Province history creation

estate = <estate>       # Adds this estate to the province
hre = yes / no          # Whether this province is in the HRE or not
capital = "<string>"    # The capital name to use for the province, otherwise the province name is used as the capital name.

reformation_center = <religion>     # Sets this province as a reformation center for the specified religion
unrest = <int>                      # Adds base unrest
<building> = yes / no               # Adds or removes the specified building

# Adds a revolt
revolt = {
    type = <rebel type>
    size = <int>
    leader = <string>
}

# History entry, can contain any of the values above as well as normal province effects
<year>.<month>.<day> = {
    <province effects>
}

Modernize Sunset Invasion

The current map of Sunset Invasion Americas has more holes than Swiss cheese

Allow for a configurable generated vassal splitoff

sensitivity and max.

Configurables to check

(Reminder for me)
Still to check:

• culture_map.txt
• government_map.txt
• religion_map.txt
• tag_mappings.txt
• version.txt

Dejure for HRE

we're ignoring it atm.

Tributary support

We need it. Also:

@slothinator

Hi!
I already wrote on the steam workshop but I'm posting the code here as requested.
To recap, I wrote the Twilight of Empires mod and I've been asked if you could turn a specific type of tributary that my mod includes into EU4 vassals (the HRE might need some ad-hoc treatment for this).
Here I'm posting once such tributary relation as written in a ck2 save file.
Code:

3069155=
{
can_call_to_war=yes
tributary=
{
tributary_type="autonomous_tributary"
tributary=3083153
income_tribute_percentage=0.39999
reinforce_tribute_percentage=0.100
}
}

Let me know if I can be of any further help!
Keep up the great work!

On rebellions

The converter currently doesn't output anything of the CK2 revolts.

(Reminder) War creation

name = "<string>"           # Name of the war in the war screen
war_goal = {
    type = <wargoal>        # The wargoal to use from 00_wargoals.txt
    casus_belli = <cb>      # The cb to use from 00_cb_types.txt
}

# Used to start the war at the specified date
<year>.<month>.<day> = {
    add_attacker = <tag>    # Adds a country to the attackers side
    add_defender = <tag>    # Adds a country to the defenders side
}

# Used to add ongoing battles 
<year>.<month>.<day> = {
    batle = { 
        name = "<string>"   # Name of province
        location = <id>     # Province the battle is in
        
        attacker = {
            commander = "<string>"  # Leader of the attacker's army
            infantry = <int>        # Number of infantry. 1 equals 1 soldier
            cavalry = <int>         # Number of cavalry
            artillery = <int>       # Number of artillery
            losses = <float>        # How many of the forces are already dead
            country = <tag>         # The country that is attacking
        }
        
        defender = {
            commander = "<string>"  # Leader of the defender's army
            infantry = <int>        # Number of infantry. 1 equals 1 soldier
            cavalry = <int>         # Number of cavalry
            artillery = <int>       # Number of artillery
            losses = <float>        # How many of the forces are already dead
            country = <tag>         # The country that is defending
        }
        
        result = yes    # Show result
    }
}

# Used to end the war at the specified date
<year>.<month>.<day> = {
    rem_attacker = <tag>    # Removes a country to the attackers side
    rem_defender = <tag>    # Removes a country to the defenders side
}

Clear saharan passes

if not owned by sub-saharan nation (check capital), the passes:
(1127, 1128), (2474, 2475) and (2932, 774, 1219) should be sterilized (Province::sterilize).
This would prevent northern powers from rapidly conquering african tribes at game start.

Splitting cultures (version 2)

Need to split Roman and Jewish cultures to avoid a monolithic world conquest

Women in history

See if it's possible to increase chance of female advisor generation for countries that have tolerance laws. Maybe this won't be possible if it's hardcoded globally.

Monarch names

See if it's possible to do a common names register from cultures (Constantinus_Constantine), and use those common names (with appropriate current culture) when building monarch name database.

Config: Shatter Empires

HRE appointee is shattered automatically, but allow for a config setting to shatter any empire into kingdoms or duchies.

Dejure permaclaims option

Add option for the permaclaims so user can toggle it.

Aztec in europe

Make their holdings in europe a colonial nation.

Forts

Where do we take them from?

Excommunication conversion

Transform ConfigurationFile into a more typical factory class

See GameRuleOption::Parser in Vic2ToHoI4 as a preliminary example

Offer an option to keep the Maghreb and Sub-Saharan Africa connected
