GUIDE: Adding new units

[Ysharma]

I just add one thing, cause it is true there's so much to say about this... I have even succeeded to limit the nuclear weapons to the civilizations that would build a national wonder "manhattan project". So ... so much we could say ....


Well the precision ...

We must precise the fact you can find several units with the same class.

<UnitClassInfo>
	<Type>UNITCLASS_TERRY</Type>
	<Description>TXT_KEY_UNIT_TERRY</Description>
	<iMaxGlobalInstances>-1</iMaxGlobalInstances>
	<iMaxTeamInstances>-1</iMaxTeamInstances>
	<iMaxPlayerInstances>-1</iMaxPlayerInstances>
	<DefaultUnit>UNIT_TERRY</DefaultUnit>
</UnitClassInfo>

When you are here you see this: <DefaultUnit>UNIT_TERRY</DefaultUnit>
This tell the game what is the default unit for this class.

In the file \Assets\xml\civilizations\CIV4CivilizationInfos.xml you can give some units to some civilizations. These units will replace the default unit. You can add several units to a civilization.

Exemple I have done

			<Units>
				<Unit>
					<UnitClassType>UNITCLASS_MUSKETMAN</UnitClassType>
					<UnitType>UNIT_FRENCH_MUSKETEER</UnitType>
				</Unit>
				<Unit>
					<UnitClassType>UNITCLASS_INFANTRY</UnitClassType>
					<UnitType>UNIT_INFANTRY_WW1</UnitType>
				</Unit>
				<Unit>
					<UnitClassType>UNITCLASS_RIFLEMAN</UnitClassType>
					<UnitType>UNIT_MINUTEMAN</UnitType>
				</Unit>
			</Units>

This command the game to use 3 special units for the france. The 3 units are from the classes of UNITCLASS_MUSKETMAN ; UNITCLASS_INFANTRY and UNIT_INFANTRY_WW1.
So basically you can add here some specific units for a civilization without limit (except the hardcoded limits).

how did you do that?

 

[The_J]

How did he do what? Be more specific.

 

[Agent327]

how did you do that?

Actually, I have the same question. I want to give the Meklars in MOO2Civ a custom MeklarScout unit. So I did what the first 3 posts said, but the MeklarScout unit doesn't show up in my testgame with the Meklars (nor is it in the Civilopedia); they just get the regular Scout. Here's what I have:

Spoiler :

</Cities>
<Buildings/>
<Units/>
<FreeUnitClasses>
<FreeUnitClass>
<UnitClassType>UNITCLASS_SCOUT_PROBE</UnitClassType>
<iFreeUnits>1</iFreeUnits>
</FreeUnitClass>
</FreeUnitClasses>
<Unit>
<UnitClassType>UNITCLASS_SCOUT_I</UnitClassType>
<UnitType>UNIT_MEKLARSCOUT</UnitType>
</Unit>
</Units>
<FreeBuildingClasses>
<FreeBuildingClass>
<BuildingClassType>BUILDINGCLASS_CAPITOL</BuildingClassType>
<bFreeBuildingClass>1</bFreeBuildingClass>
</FreeBuildingClass>
</FreeBuildingClasses>

 

[The_J]

Is only the starting unit the problem, or does the scout not appear at all in the game?

 

[Agent327]

They just get the regular Scout; so Scouts are in (they always were), but the MeklarScout unit model doesn't appear. (I'm sure I overlooked/omitted something...)

If you want to create a UU you do not change UnitClassInfos. Check out how UUs are set up in the regular game. Basically all you do is create a new UnitInfos entry for your new UU, and then define that as a replacement unit in CivilizationInfos. Again look at a regular BtS UU to see how it's done, it's pretty straightforward.

 

[Agent327]

Ah, OK - I'll check. Thx.

erm...

                <Unit>
                    <UnitClassType>UNITCLASS_SCOUT_I</UnitClassType>
                    <UnitType>UNIT_MEKLARSCOUT</UnitType>
                </Unit>
            </Units>

And looking closer at this, it sure should be this here:

            <FreeUnitClasses>
                <FreeUnitClass>
                    <UnitClassType>UNITCLASS_SCOUT_PROBE</UnitClassType>
                    <iFreeUnits>1</iFreeUnits>
                </FreeUnitClass>
                <FreeUnitClass>
                    <UnitClassType>UNITCLASS_SCOUT_I</UnitClassType>
                    <iFreeUnits>1</iFreeUnits>
                </FreeUnitClass>
            </FreeUnitClasses>

 

[Agent327]

OK, now I'm confused... What should I do about it?

 

[phungus420]

I have no idea what The_J is saying either.

Look JEELEN, just do this: Search In Files for _JAGUAR in the XML folder using Notepad++ (have it search in child folders as well). This will show you all the places _JAGUAR is in the XML (UnitInfos and CivilizationInfos and some text files). Then just copy what the BtS devs did to make a UU for a standard BtS UU for your unique unit for your mod.

 

[The_J]

About what?

I say, that you've misread the schema for the free units.
Look at it again closely.

If i read that right, it IS already a real UU. It has UNITCLASS_SCOUT_I as unitclass, which i guess, is the normal unitclass, and UNIT_MEKLARSCOUT as unittype.

That is correct. So what is wrong? (Looking at it closely, I don't see it; just tell me - or highlight in the section - what I'm missing or did do wrong. This is my very first try at adding a custom model and I need to add plenty more.) The unit (nor a button for it) is showing up when testplaying the Meklars; it also doesn't show in the Civilopedia and I changed all the files according to the tutorial in posts 1-3.

 

[The_J]

You don't see it in the civilopedia?
During a game, or before starting a new one?

 

[Agent327]

No, no and no. (Although I don't quite see how I could see it before starting a game...)

 

[The_J]

I mean, directly after loading in the civilopedia, without starting a game.
...cache maybe?

 

[Agent327]

If you mean I should (have) clear(-ed) out my cache, I didn't. (It's mentioned in an earlier post, but it's not in posts 1-3 as a necessary step. Should it be?) Would that help to fix it?

 

[The_J]

It's worth a try.

 

[Agent327]

OK, will do.

 

[Ysharma]

i did everything but when i go to its civilopedia entry it only shows a box with a PICTURE OF THE BUTTON
at least it started and shows it in the civilopedia
\\

 

[The_J]

Is only the button there, or is the button there instead of the unit?
In the first case: Check again the path to your art files. There's maybe a mistake in one of the folder names in your artDefines_Units.xml.
