Science pack

To change properties of your science pack, you can add a table on your science pack declaration

{
    type = "tool",
    name = "rocketry-science-pack",
    -- Science pack stuff ... 

    nobelium_science = {
        -- Nobelium stuff ...
    }
}

Fields

progress_stage: string

default: "pre-nobelium"

This govern when your science packs comes into play. This takes specific values

• "pre-promethium": Your science pack is required for promethium science. Use this if you gate the vanilla science packs with it.
• "pre-nobelium": Your science pack is not required for promethium science. It's the default behaviour
• "post-promethium": Your science pack require promethium science. If you need to expend deeper in the promethium science pack, this is what you need

ignore_autoadd: boolean

default: false

Prevent this science pack to be auto added to technologies requesting all science packs of a stage

Technology

To change properties of your technology, you can add a table on your technology declaration

{
    type = "technology",
    name = "rocket-booster",
    -- Technology stuff ... 

    nobelium_science = {
        -- Nobelium stuff ...
    }
}

Fields

add_minimum: string?

This automatically add missing science packs for the stage of your technology. This takes in a specific string value:

• "post-promethium": This will add all the vanilla space age science packs + all the science packs that are set as "pre-promethium".
• "post-nobelium": This will add the science packs from "post-promethium" + all the science packs that are set as "pre-nobelium" (This include the ones with nobelium_override not set).

Sadly, the standard factorio API doesn't have a clear way to say "This is a science pack". So modded science packs cannot be easily recognized.

This means only science packs that either:

• Have nobelium_science.progress_stage set
• Are able to be put in the base vanilla lab

... can be autoadded
