data.raw["map-gen-presets"]["default"]["foo"] = {
    order = "1",
    basic_settings = {
        research_queue_from_the_start = "always"
    }
}

The code you provided would work either way, it is not a basic setting, but would be in `difficulty_settings`, along with tech price multiplier and recipe difficulty

There appear to be two problems here:

1. The documentation is wrong. basic_settings.research_queue_from_start doesn't do anything. It should be advanced_settings.difficulty_settings.research_queue_setting.
2. Support to load this setting from presets is missing.

Both should be fixed for the next release, and then you can do like this:

Code: Select all

data.raw["map-gen-presets"]["default"]["foo"] = {
    -- Important that order be > "a" so that this preset does not get loaded by default.
    -- The 'default' preset needs to be be first because it matches what the
    -- newly-initialized map generator GUI does.
    order = "c",
    advanced_settings = {
        difficulty_settings = {
	    research_queue_setting = "always"
	}
    }
}

Thanks for the fix and the documentation update. I think it would also be a lot easier to understand the documentation for this if

a) the section for MapGenSettings mentioned the advanced_settings field
b) there was a section for the advanced settings type / dictionary
c) the section for advanced settings mentioned the field difficulty_settings

In general I found it very hard to understand the documentation for this part of the api and pieced a lot of my understanding together from some other mods and a few forum posts, which there are not a lot of.

This is most likely the case because you are looking at the wrong documentation. lua-api.factorio.com documents runtime scripting, not the data stage. The data stage is documented on the wiki: https://wiki.factorio.com/Prototype_definitions

The documentation for https://wiki.factorio.com/Types/MapGenPreset mentions all the fields that you are looking for.
