[0.10.12] misleading message on productivity modules use

[arl85]

if I try to insert a productivity module into an assembly machine I receive the message "Production module is usable on intermediate products"

If it is an error, I expect something like "is not usable..."

further distinction between intermediate products and other is not clear and/or explained anywhere.

The "intermediate products" have their own tab in the crafting window (engine symbol). Everything in that tab works with the modules.

Myabe if it said "is only useable", it looks like there is some kind of modifier missing, some might assume 'only', some might assume 'not'.

The "intermediate products" have their own tab in the crafting window (engine symbol). Everything in that tab works with the modules.

well, not exactly: wood is in third tab but cannot work with modules.

It can ONLY work on intermediate items, however, on top of that restriction is also a filter, if your item is not on the filter, it won't work on it even if it is an intermediate. this is to stop things such as oil barreling, you can't use it on a filling a barrel, then unfilling a barrel. if you could, you could put 2 of these factories back to back to fill and unfill oil, getting free barrels and oil in the process.

Wait, productivity modules can only be used on intermediate products?

*loads up game to check*

Dammit. I thought I was being clever by assuming I could use productivity modules in every step of module-III production to dramatically reduce raw material cost. Now I've got to redo all those painstakingly-calculated numbers by going through the burdensome step of multiplying everything by 2, and by making the module blueprint twice as large. Nobody's got time for that.

(Incidentally, the wiki should probably mention this restriction, just so other OCD planners can avoid making the same mistake.)

Ok, I've done it, but the sense of a wiki is to make it yourself. https://forums.factorio.com/wiki/inde ... tle=Module

ok, wood seems to be an intermediate product but still I cannot use productivity module to produce it.

Wood is currently raw material:

Code: Select all

    <wood>
      <flags>
        <flags>goes-to-main-inventory</flags>
      </flags>
      <type>item</type>
      <name>wood</name>
      <stack_size>50</stack_size>
      <order>a[wood]</order>
      <subgroup>raw-material</subgroup>
      <icon>__base__/graphics/icons/wood.png</icon>
      <fuel_value>0.6MJ</fuel_value>
    </wood>

you're right, but still its creation cannot use productivity modules.

But I found how this thing is managed.
indata\base\prototypes\item\module.lua there's the productivitymodulelimitation function that lists products you can use prod module with.

Code: Select all

function productivitymodulelimitation()
return {"sulfuric-acid",
        "basic-oil-processing",
        "advanced-oil-processing",
        "heavy-oil-cracking",
        "light-oil-cracking",
        "solid-fuel-from-light-oil",
        "solid-fuel-from-heavy-oil",
        "solid-fuel-from-petroleum-gas",
        "lubricant",
        "iron-plate",
        "copper-plate",
        "steel-plate",
        "stone-brick",
        "sulfur",
        "plastic-bar",
        "empty-barrel",
        "iron-stick",
        "iron-gear-wheel",
        "copper-cable",
        "electronic-circuit",
        "advanced-circuit",
        "engine-unit",
        "electric-engine-unit",
        "processing-unit",
        "explosives",
        "battery",
        "flying-robot-frame",
        "science-pack-1",
        "science-pack-2",
        "science-pack-3",
        "alien-science-pack",
      }
end

I'm not sure if excluding wood has been done by purpose or by mistake
