After many hours of game play, I got it into my head to mod the 1862 West Campaign.sct file based on Dyer's Compedium, and other sources.
Through trial and error I have successfully created Porter's Mortar Flotilla, edited Farragut's OOB, edited Butler's OOB, modified the volunteer brigade to suit my purposes, and created a new pioneer company unit to represent Brown's Sappers and Miners. So creating steam sloops, and adding brigadeers Phelps, Williams, and Shepley, are on the agenda.
But then I get to looking at the scriptwest62.ini file, and I see that Porter is attached to the Mississippi Fleet at Cairo. That won't do. Let's add Charles H. Davis, change the name to Western Gunboat Flotilla and modify the order of battle. Like so:
SelectRegion = $Alexander_IL
SelectFaction = USA
SelectRegion = $Alexander_IL
CreateGroup
Posture = $Defensive
SetKind = $Nav
Entranch = 0
FixType = 0
SetName = Western Gunboat Flotilla
Apply
CreateUnit
SetType = $uni_USA_Foote
SetName = Andrew H. Foote
Apply
CreateUnit
SetType = $uni_USA_CHDavis
SetName = Charles H. Davis
Apply
CreateUnit
SetType = $uni_USA_IroIL
FlavorName = Lt. James M. Pritchett
SUFlavorName = USS Cairo
SetLevel = 1
SetName = USS Cairo
Apply
So on. And so forth.
But what happens when I fire up the game, is that I see what the original file wants:
SelectRegion = $Alexander_IL
SelectFaction = USA
SelectRegion = $Alexander_IL
CreateGroup
Posture = $Defensive
SetKind = $Nav
Entranch = 0
FixType = 0
SetName = Mississippi Fleet
Apply
CreateUnit
SetType = $uni_USA_Foote
SetName = Andrew H. Foote
Apply
CreateUnit
SetType = $uni_USA_Porter
SetName = David D. Porter
Apply
CreateUnit
SetType = $uni_USA_IroIL
FlavorName = Capt. W. Gordon
SUFlavorName = USS Cairo
SetLevel = 1
SetName = USS Cairo
Apply
So on. And so forth.
When I was editing the 1862 West Campaign.sct file the errors were immediately apparent, even if it took a while to figure out the solution.
In this case. There are no errors. The game seems to be pulling the original code from somewhere. But where? I've deleted cache files, and generally poked around and opened just abut everything but the graphics files. What am I doing wrong here?
I sure hope there is someone out there.
