How do you change the production cost of a building/unit?

[bb82]

I'd like to change the production cost/shields of units and buildings. I'd like to play a marathon type game, but keep many buildings and units at a lesser cost. Meaning, I like the high research times and turns, but I want to be able to enjoy certain types of units for a longer period of time. So I dont want their production cost to increase, just because I want a longer game.

What's the easiest way to change the costs? What file, formula, etc.?

If you do not want to change all units: Units\Civ4UnitInfos.xml, search for iCost.

For all units: Civ4GameInfo\Civ4GameSpeedInfo.xml,

<iTrainPercent>200</iTrainPercent>
			<iConstructPercent>300</iConstructPercent>
			<iCreatePercent>300</iCreatePercent>

these values.


And welcome to CFC .

Thanks for the help.

Any chance I can get more info about how to do this and what those values are, based on what I actually want to do?

Let me be more specific, I want to make unit/building costs/shields the same values that they are in a normal game, even though i'm in a marathon game. Except settlers. I actually want to increase their cost in a marathon game by about 50%.

In that case..

In the copies of the files in your mod folder... (NOT the originals)

In Civ4GameSpeedInfo.xml, set all three of the values that The_J listed to 100 - they say "Set this to cost to 100% (or whatever the value is) of the normal cost"
iTrain = unit costs
iConstruct = building costs
iCreate = research costs

Then in Civ4UnitInfos.xml, increase the value for the settler's iCost entry to whatever you want it to cost.

If I did all of that:

Would it affect the current game i'm in?

Or when I start my next BTS game, with marathon selected, it would be how I want it?


Thanks again.

I'm pretty confused. Why the mod folder? I want to do this for games in CivIV bts. So wouldn't I be looking in the assets folder for bts? Wouldn't the mod folder affect the mod/senerio games?

Aslo, when I found the file, how do I edit it? Seems I can't even open it. Do I need a special tool to edit it and save it? Do I have to recompile it or just edit it and save the file? Will any text editor work, notepad even?

I think I was able to figure it out. I changed the following to 100 and my current game reflected this, as soon as I reloaded BTS. But I noticed that the settlers value stayed the same. Shouldn't it's value also change? It stayed at 300 shields, when the normal value is 100 shields. Do I manually have to do settlers?

iTrain = unit costs
iConstruct = building costs

You can open the XML files with Notepad, just right-click and select "open with" and then choose Notepad or any other text editor (Not Word, it's not text editor).

You should really make a mod folder and put your modded files there or put the files in the <My Documents>\My Games\Civilization\CustomAssets, which will override the standard files.

If you make changes directly to BtS, you might break something. Making a mini-mod would spare you a lot of potential problems.

I think the settler cost varies depending on the gamespeed. But in CIV4UnitInfos.xml, you can edit the iCost tag for the settler.

The reason to do it in a Mod is so that you always have the original files around - this can be impotant if you ever screw something up.

Go to your BTS mods folder, create a new folder inside it. Copy the desired files to subfolders named just like they are in the Assests folder. Change those copies.

And yes, any text editor will do.
