In 1.1.55 and before you could obtain the the autoplace_specification from a tree LuaEntityPrototype, but in 1.1.56 this isn't obtainable and it isn't listed as an intentional loss in the 1.1.56 changelog. its also still in current documentation.

Prototypes being obtained via the below snippet:

Code: Select all

game.get_filtered_entity_prototypes({{filter = "type", type = "tree"}, {mode = "and", filter = "autoplace"}})

EDIT: on trying more code I think its an internal Factorio error on trying to get the autoplace_specification. As I get the below error when I try to check if autoplace_specifiation is nil:

Code: Select all

Value can't be NaN. in property tree at ROOT.coverage

Code: Select all

local treeEntities = game.get_filtered_entity_prototypes({{filter = "type", type = "tree"}, {mode = "and", filter = "autoplace"}})
for _, prototype in pairs(treeEntities) do
    if prototype.autoplace_specification ~= nil and prototype.autoplace_specification.peaks ~= nil then
        log(prototype.name)
    end
end

Thanks for the report. This is fixed for the next release.
