Does anyone know how to read the map settings for resource richness for each of the resources (iron, copper, coal ect)?

Solved, answer:

game.print(game.player.surface.map_gen_settings.autoplace_controls["iron-ore"].richness)

That throws a nil value error on player, however game.print(game.surfaces['nauvis'].map_gen_settings.autoplace_controls["iron-ore"].richness) works. Thanks for the pointer.

Sorry the example was for console use.


Also not sure where you are collecting this data at but using hard coded surfaces (i.e. surfaces['nauvis']) can cause undesired behavior on other surfaces from mods.

I'm unfamiliar with how the surfaces work but 'nauvis' is used in the base mod files. Maybe game.surfaces[1] would also work.

game.surfaces[1] and surfaces['nauvis'] do the same thing (both refer to the nauvis surface)

How to handle it would be determined on where and how the code to get the data is used and or accessed.

I.E if you are getting the data during an event with a player or entity you can retrieve the surface from them.

script.on_event(defines.events.on_built_entity, function(event)
-- for the surface of the event entity
game.print(event.entity.surface.map_gen_settings.autoplace_controls["iron-ore"].richness)

-- for the surface of the player that built the entity
game.print(game.players[event.player_index].surface.map_gen_settings.autoplace_controls["iron-ore"].richness)
end)
