Yes. If you are adding a completely new general you need to add them into the game!
The easiest way is to go the events folder and find USA leaders or CSA leaders events. These are script files that contain most (but not nearly all) of the leader creation events for both sides. Again, I recommend using Notepad++ to open and edit them.
Then find where you want to include the new leader and insert him.
For example. Using Chamberlain you might want to insert him in with George Custer (he is one of the last Union generals to arrive in the game, early in 1864 which is earlier than Chamberlain became a General - June, 1864 - but close enough for government work.) You could also create a whole new event for Chamberlain too, but let's keep it simple to start with.
First, find this entry:
Code: Select all
SelectFaction = USA
StartEvent = evt_nam_USA_Custer|1|1|NULL|NULL|NULL|NULL
Conditions
MinDate = 1864/03/01
MaxDate = 1864/03/31
EvalUnqUnit = George A. Custer;NOT
SelectFaction = USA
SelMostNumGroup = Area $Mid_Atlantic;CPCount
GenMsg
SelectRegInArea = $MD;OwnedVPCities;CondSkip
GenMsg
PickFromRegList = NotEnemy
GenMsg
EvalRegionSel = NULL
Actions
GenMsg
SelectFaction = USA
CreateGroup
Posture = $Defensive
SetKind = $Land
Entranch = 0
InCS = 0
FixType = 0
SetName = G. Custer
Apply
CreateUnit
SetType = $uni_USA_Custer
SetName = George A. Custer
Apply
EndEvent
Then copy the last section from "CreateUnit" to "Apply" and then paste it below the first one:
Code: Select all
CreateUnit
SetType = $uni_USA_Custer
SetName = George A. Custer
Apply
CreateUnit
SetType = $uni_USA_Custer
SetName = George A. Custer
Apply
Then change the information in the second copy from Custer to Chamberlain. The only real important part is the "SetType" section, I have found that the "SetName" area doesn't really seem to matter, BUT it's always good practice to change it as well, if nothing else it makes reading the code easier. If you want you can also seek out the "local_strings_CW2.csv" file and change the description of the event to include Chamberlain, but that is not required.
That should do it. If you want to test your new general, I recommend, first inserting him in the 61 Generals Pool (which will appear on turn 2 of an April start game). This will let you verify that he is everything you want him to be before putting him where he belongs in 1864.
Let me know if you have any questions.
