limiting production of a unit for the whole game

Numetalfan

I want a unit to be build only once or a few times in a game, doesn't matter by whom.
reaching that limit auf builds should end this production option forever for everyone

an example would be:

Switzerland is neutral with a factory
who captures Switzerland will get the mountain troops via a trigger, e.G. for Germany
..
<option name="productionRule" value="productionGermany:mountain troops"/>
...
I want to have a total limit of 3 units of those mountain troops to be build in the whole game.

let's say Germany captures Switzerland and builds all 3 of them
later Switzerland captured by UK. How do I prevent that UK also builds those units?

So any <option name='uses' value='1'/> will not help.
It limits one nation (e.g. Germany), while another one (Italy) can still use it.

same with <option name='maxBuiltPerPlayer' value='1'/>
that will also limits only one nation.

<option name='unitPresence' value='mountain troops' count='1'/>
on the whole map is also useless, the 3 build units might have been taken as casualities in a battle, so this would allow to build new ones.

I need a variable that is 0 at the start of the game and will finally reach 3.
So I could make a condition out of it.

Any Idea how to solve this this?

Not to hard. I would use a 'switch' condition to insure that only one player received the captured unit, and a limited 'resource' to build that captured unit.

<!-- Add to the resourceList -->
<resourceList>
   ...
   <resource name="CapturedMountainTroops"/>
</resourceList>
<!-- Add to production -->
<production>
   ...
   <productionRule name="buyCapturedMountainTroops">
      <cost resource="PUs" quantity="4" />
      <cost resource="CapturedMountainTroops" quantity="1"/>
      <result resourceOrUnit="Mountain troops" quantity="1"/>
   </productionRule>
   ...
</production>

<!-- The 'switch' trigger -->
<attachment name="conditionAttachmentCapturedMountainTroops" attachTo="Switzerland" javaClass="games.strategy.triplea.attachments.RulesAttachment" type="player">
   <option name="switch" value="true"/>
</attachment>

<!-- If  Germany captures the factory -->
<attachment name="triggerAttachmentGermanyCapturesSwisFactory"attachTo="Germans" javaClass="games.strategy.triplea.attachments.RulesAttachment" type="player">
   <!-- Add 'switch' conditions -->
   <option name="conditions" value="...:conditionAttachmentCapturedMountainTroops"/>
   <!-- Give Germany 3 resources -->
   <option name="resource" value="CapturedMountainTroops"/>
   <option name="resourceCount" value="3"/>
   <!-- Change 'switch' to false -->
   <option name="playerAttachmentName" value="RulesAttachment" count="conditionAttachmentCapturedMountainTroops"/>
   <option name="playerProperty" value="switch" count="false"/>
</attachment>

Because every player should check the same 'switch' once its false it will block all other players and the resource will insure only a certain amount of units will be built.

Next...
