Leaders are defined in the [MOD_FOLDER]\Assets\XML\Civilizations\CIV4LeaderHeadInfos.xml file. Inside of it, each leader is defined between <LeaderHeadInfo> tags. For example, in ExtraModMod Alexis appears as:
Code:
[b]<LeaderHeadInfo>[/b]
<Type>LEADER_ALEXIS</Type>
<Description>TXT_KEY_LEADER_ALEXIS</Description>
<Civilopedia>TXT_KEY_LEADER_ALEXIS_PEDIA</Civilopedia>
<ArtDefineTag>ART_DEF_LEADER_ALEXIS</ArtDefineTag>
<iWonderConstructRand>25</iWonderConstructRand>
...
<ReligionWeightModifiers>
<ReligionWeightModifier>
<ReligionType>RELIGION_COUNCIL_OF_ESUS</ReligionType>
<iWeightModifier>25</iWeightModifier>
</ReligionWeightModifier>
<ReligionWeightModifier>
<ReligionType>RELIGION_THE_ASHEN_VEIL</ReligionType>
<iWeightModifier>25</iWeightModifier>
</ReligionWeightModifier>
</ReligionWeightModifiers>
[i]<LeaderCategory>LEADERCATEGORY_STANDARD</LeaderCategory>[/i]
[b]</LeaderHeadInfo>[/b]
The main reason about why you can't just copy leaders from a mod and paste them in another is that leaders can have a different format in each mod. For example, that XML code comes from ExtraModMod, which includes a system for leader categories. If a leader of ExtraModMod were pasted into More Naval AI, you would get an error on start up and it wouldn't load correctly.
There is nothing preventing you from just adding another leader to the mod and changing the value of each field to the value of the leader you want to import. When it is not possible, you can always assign something that makes sense for the new leader. The most complicated part is the <ArtDefineTag>. This points to yet another XML section that needs to be defined, in this case in the [MOD_FOLDER]\Assets\XML\Art\CIV4ArtDefines_Leaderhead.xml file.
Code:
<LeaderheadArtInfo>
<Type>ART_DEF_LEADER_ALEXIS</Type>
[b]<Button>,Art/interface/LeaderHeads/Alexis button.dds</Button>
<NIF>art/interface/LeaderHeads/Alexis.dds</NIF>[/b]
<KFM/>
<NoShaderNIF/>
<BackgroundKFM/>
</LeaderheadArtInfo>
For this, you will need to find the art for the leader button and portrait in the original mod. This is a kind of long process for which there are quite a few tutorials in the pertinent section of the CivFanatics forums. I recommend ommitting this process (and just using the ArtDefineTag of another leader) until everything else already works.
After adding the leader to CIV4LeaderHeadInfos.xml you will need to add it to its civilization. In [MOD_FOLDER]\Assets\XML\Civilizations\CIV4CivilizationInfos.xml, you can find the following code in the middle of the Calabim:
Code:
<Leaders>
[b]<Leader>
<LeaderName>LEADER_ALEXIS</LeaderName>
<bLeaderAvailability>1</bLeaderAvailability>
</Leader>[/b]
<Leader>
<LeaderName>LEADER_FLAUROS</LeaderName>
<bLeaderAvailability>1</bLeaderAvailability>
</Leader>
<Leader>
<LeaderName>LEADER_DECIUS_EXTRA</LeaderName>
<bLeaderAvailability>1</bLeaderAvailability>
</Leader>
<Leader>
<LeaderName>LEADER_MAHON_EXTRA</LeaderName>
<bLeaderAvailability>1</bLeaderAvailability>
</Leader>
</Leaders>
Adding another similar section pointing to the LeaderName you chose for your leader will add that leader to that civilization. If everything went fine, you will be able to play with your new leader.
