How can you count up how much units of a category you got?

Let's say I need to know how many units of category "individual" i have.
In the validator I put something like:

for i,unit in twArmy:units() do

if (unit.categories.category=='Individual') then
....


It doesn't seem to be recognized, I assumed this matched the Units.xml structure, but I guess I was wrong...

can anyone help ?

Category is not exposed inside the objects passed into the LUA interpreter.
For the validator on my list, I added an extra field with the same contents as the category and used that to verify it.

To see what fields are available and how they are addressed, you can pass a complex object to the twNotice() output function. Like this

twNotice(twArmy)

for i,unit in twArmy:units() do
twNotice(unit)
for j, bonus in unit:bonuses() do
twNotice(bonus)
end
end

That will give you the structure of all the objects you have to play with.

JohnOC have hit the nail on the head.
Sorry for holes in the documentation on this matter.
Maybe I should add categories to Lua interface?


BTW: You ruleset does not work in online editor because of the default display XML.
You should use 'default' field instead of 'value' here.
You have something like this:

<displayFields>
    <field>
      <name>something</name>
      <value>1</value>
    </field>
</displayFields>

it should look like this:

<displayFields>
    <field>
      <name>something</name>
      <default>1</default>
    </field>
</displayFields>

I would find that very useful for my code. Anyone writing a Warhammer 40k ruleset needs to be able to validate numbers of allowed choices by category, and it makes sense not to have to duplicate that info in the unit.xml.
