Are you asking how to mod it to go higher, or just how to increase your fleet cap?

I think there's some posts in the mod forum about increasing fleet cap.

change
maxShipSlots 2300
in the gameplay.constant file.

Then change each RESEARCHSUBJECT_MAXSHIPSLOTS[RACE][0-7].


Tip: instead of changing each file, just change this line in each xxxxRace0 file:
modifierType "ShipMaxSlots"
baseValue 100.000000
Make that more, that's the starting number.

I don't recommend making the fleet cap much higher, as it bogs down your system on 8+ player maps and it doesn't improve tactical considerations much. And the AI will out-micro-manage you with larger fleets.

Or you can change each ship's slot count, but that's a lot more files to edit.

Dammit, I have already posted this somewhere, but I'll post it again. This is originally from an email I sent to another asking a similar question. And seeing as you failed to detail what you mean by "Fleet Capacity", I will give you the walkthroughs for Capital ships, Fleet Supply, and the overall ships ingame.

Capital Ship Pop

Ok. The files you need to change are in the 'GameInfo' folder.
They are named like so:
RESEARCHSUBJECT_MAXCAPITALSHIPSTECH0
RESEARCHSUBJECT_MAXCAPITALSHIPSTECH1
RESEARCHSUBJECT_MAXCAPITALSHIPSTECH2... up to level 7, they're for the TEC Empire, the Vasari are PHASE, and the Advent are PSI.

Open number 0 for each race and change this line:

researchModifier
. . . . modifierType "CapitalShipMaxSlots"
. . . . baseValue 1.000000 <--
. . . . perLevelValue 1.000000

to something like 5.000000, or however many capital ship slots you want to begin with. This would give you a starting pop of 5.


Now, in all the other files like the ones labelled above, change this line:

researchModifier
. . . . modifierType "CapitalShipMaxSlots"
. . . . baseValue 0.000000
. . . . perLevelValue 1.000000 <--

to something like 5.000000, or whatever you want. This will increase the pop cap when you research that level in the Logistics tab.

So, basically, if you want to start with 100 pop cap for capital ships, change the first files, the ones ending in 0, to 100.000000.

Fleet Supply and Total Ships Ingame

You need to alter another set of files. Like the others but labeled like so:

RESEARCHSUBJECT_MAXSHIPSLOTSTECH0.entity
RESEARCHSUBJECT_MAXSHIPSLOTSTECH1.entity
RESEARCHSUBJECT_MAXSHIPSLOTSTECH2.entity... etc... up to 7

TECH, PHASE, PSI, as before.

Now, open each one and look for:
researchModifier
. . . . modifierType "ShipMaxSlots"
. . . . baseValue 100.000000
. . . . perLevelValue 150.000000 <-- Fleet Supply
researchModifier
. . . . modifierType "IncomePercLost"
. . . . baseValue 0.000000
. . . . perLevelValue 0.093750 <-- Upkeep Percentage

Just change them in each file, say add 50 to every level's Supply, and take 5% off every Upkeep.

To increase the maximum ships allowed ingame (total for each player), then, in the same folder(GameInfo) as before, open the file: gameplay.constants

The 3rd line down has:
maxShipSlots 2300

Change this to however many ships you total fleet supply and Capital ships population will allow.

If you STILL have questions about this (I can't read the file, its in Binary. Where are the files. Where are the folders, etc), then I suggest you either look around the forum for tutorials and walkthroughs, download the Beta Mod Tools and read the tutorial included, or give up modding.

Edit: I don't believe it, it was on first page of the Modding forum. For goodness sake:

TheRenegade What you have said to me makes no sense at all what you're on about, im only interested in changing the fleet number which always seems to hover around zero to a higher figure so I can build more ships.

Hi people,

  I am having a problem modding the files as above. I have found the correct files and looked at the guides but ehrn I open the ResearchSubject Max Ship Slots I get the following:

  I do not have this.

researchModifier

. . . . perLevelValue 150.000000.

 

  I just wondered if I have done something wrong or have missed something. Any help would be a huge help, thanks.
