Luaentityprototype doesnt contain key energy_source, even though it is filtered for craftingmachine

[hamgurmber]

Code: Select all

for _, entity in pairs(game.get_filtered_entity_prototypes({{filter = "crafting-machine"}})) do
	if entity.energy_source == "burner" and need_fuel(entity) == false then
		_fuel_list[entity.name] = _fuel
	end
	Kmachine[entity.name] = true
end

the above code causes the error "LuaEntityPrototype doesn't contain key energy_source" and i am not sure why

[FuryoftheStars]

Because LuaEntityPrototype, for any entity, does not have that key. Keys from prototypes in data stage do not always translate 1:1 to LuaEntityPrototype in control stage. Many aren't even available to read.

Search that page for "energy source" (note no underscore) and you'll get hits on what it has instead.

Yeah, but its filtered for crafting machine, which does have that key

In data stage they do. Not in the control stage.
