How to calculate the consumption of a ware for a station?

[thijso]

Looking through the xml files of the game, I've managed to come up with this:

Code: Select all

<find_object_component groupname="$stationmodules" object="$srcStation" checkoperational="true" class="class.module" multiple="true"/>
<debug_to_file chance="$debugchance" name="$debugFileName" directory="'DumbMule'"
               text="' %s modules on %s %s'.[$stationmodules.count, $srcStation.idcode, $srcStation.knownname]" />

<do_all exact="$stationmodules.count" counter="$ModuleCounter">
    <debug_to_file chance="$debugchance" name="$debugFileName" directory="'DumbMule'"
                   text="' %s module: %s : %s'.[$stationmodules.{$ModuleCounter}, $stationmodules.{$ModuleCounter}.name, $stationmodules.{$ModuleCounter}.class]" />
    <debug_to_file chance="$debugchance" name="$debugFileName" directory="'DumbMule'"
                   text="' %s : %s : %s'.[$stationmodules.{$ModuleCounter}, $stationmodules.{$ModuleCounter}.productionvolume, $stationmodules.{$ModuleCounter}.consumptionvolume]" />
</do_all>

This kinda works, except for the last part. I get something like this in my logs:

Code: Select all

As you see, the productionvolume and consumptionvolume are always null.

I expected them to work, as I see the following in the game files (finalisestations.xml):

Code: Select all

<!-- Calculate the throughput of the station (volume of wares being produced and consumed on a station) -->
<set_value name="$ProductionVolume" exact="0" />
<set_value name="$ConsumptionVolume" exact="0" />
<do_all exact="$PlannedModules.count" counter="$ModuleCounter">
  <do_if value="$PlannedModules.{$ModuleCounter}.isclass.production">
    <set_value name="$ProductionVolume" operation="add" exact="$PlannedModules.{$ModuleCounter}.productionvolume" />
    <set_value name="$ConsumptionVolume" operation="add" exact="$PlannedModules.{$ModuleCounter}.consumptionvolume" />
  </do_if>
</do_all>

So it seems those $PlannedModules are not the same as the modules I get. I'm stumped...

Any help greatly appreciated!

So, I've realized that I should just be able to hardcode the consumption of each type of module, but I'd rather not do that.

Am I wrong in thinking it should be possible to discover this through the code?

[thijso]

So I ended up hardcoding the consumption values. I used lists as there I can just use plain old strings. It's clunky, but it works. And since the calculations are restricted to those instances where a ware is also a resource (not that often I find in my use cases), I don't think the impact is too bad. What I've got now is:

Code: Select all

Then later if the ware is a resource, I check all the modules at the station and add up the amounts each module needs of the resource per hour. Then, using the parameter that you have to set at the start, it makes sure the mule always leaves that amount of resources at the station.

Code: Select all

<!-- we shouldn't empty out resources -->
<do_if value="$srcResources.indexof.{$ware} gt 0">

  <set_value name="$stationmodules" exact="[]" />
  <find_object_component groupname="$stationmodules" object="$srcStation" checkoperational="true" class="class.module" multiple="true"/>

  <set_value name="$ware_consumption" exact="0" />

  <do_all exact="$stationmodules.count" counter="$ModuleCounter">
    <do_if value="$stationmodules.{$ModuleCounter}.isclass.habitation">

      <set_value name="$modulename" exact="$stationmodules.{$ModuleCounter}.name" />
      <set_value name="$mod_index" exact="$HabConsumptions.indexof.{$modulename}" />
      <do_if value="$mod_index gt 0">
        <set_value name="$ware_name" exact="$ware.id" />
        <set_value name="$ware_list" exact="$HabConsumptions.{$mod_index+1}" />
        <set_value name="$ware_idx" exact="$ware_list.indexof.{$ware_name}" />

        <do_if value="$ware_idx gt 0">
          <set_value name="$ware_consumption" operation="add" exact="$ware_list.{$ware_idx+1}" />
        </do_if>
      </do_if>
    </do_if>
    <do_if value="$stationmodules.{$ModuleCounter}.isclass.production">

      <set_value name="$modulename" exact="$stationmodules.{$ModuleCounter}.name" />
      <set_value name="$mod_index" exact="$ProdConsumptions.indexof.{$modulename}" />
      <do_if value="$mod_index gt 0">
        <set_value name="$ware_name" exact="$ware.id" />
        <set_value name="$ware_list" exact="$ProdConsumptions.{$mod_index+1}" />
        <set_value name="$ware_idx" exact="$ware_list.indexof.{$ware_name}" />

        <do_if value="$ware_idx gt 0">
          <set_value name="$ware_consumption" operation="add" exact="$ware_list.{$ware_idx+1}" />
        </do_if>
      </do_if>
    </do_if>
  </do_all>

  <debug_to_file chance="$debugchance" name="$debugFileName" directory="'DumbMule'"
                 text="' total consumption = %s'.[$ware_consumption]" />

  <set_value name="$maxToGet"
             exact="$srcStation.cargo.{$ware}.count - ($ware_consumption * $minResourceFactor)" />
  <debug_to_file chance="$debugchance" name="$debugFileName" directory="'DumbMule'"
                 text="'resource at station: getting %1 of %2 (requested was %3)'.[$maxToGet,$srcStation.cargo.{$ware}.count,$cargoHauled]" />

  <remove_value name="$ware_consumption" />
  <remove_value name="$stationmodules" />

  <do_if value="$maxToGet le 0">
    <!-- not enough available for trade, skip -->
    <continue />
  </do_if>

  <set_value name="$cargoHauled" exact="[$cargoHauled,$maxToGet].min" />
</do_if>

So that works, but if anyone has a idea how to do this better (the list traversal is a little wasteful) I'm open to suggestions...

[kuertee]

What happens with "$stationmodules.{$ModuleCounter}.name" when the game is played with the German language?
I mean in regards to your lists.
Will it's data be found regardless of language?
I don't know. It may be found. It may not.
(Just thinking out loud.)

[thijso]

Yeah, that's gonna break it. I think.
That's why I was looking for a 'standard' way to do it. The information is there in the logical overview of the station, so why can't I access that data direct?

[kuertee]

did you look if they are available as a property of a station or module as listed in the scriptproperties.xml file in the library folder?
(unfortunately, my games drive died JUST last night, so I can't check and can't give you an exact answer.)

[thijso]

The two params I mention in the first post (productionvolume and consumptionvolume) are listed as properties of macro with base type dbdata.

I also see production as a type of module with products and resources properties.

I have tried to get values for all of these, but no luck. Maybe I'm doing it wrong.

What I do when I find a property that could be what I need but don’t know how to use, I do a regex search for how it is used in the Mission Director (md) folder.
