making a furnace accept coal + custom item

[Kriogenic]

I am trying to make a furnace take two inputs which I would like to be coal and a custom item which name at the moment is new-fuel

I have written it so far like so

Code: Select all

 {
    type = "item",
    name = "new-fuel",
    icon = "__ModTest__/graphics/icons/new-fuel.png",
    flags = {"goes-to-main-inventory"},
   subgroup = "raw-material",
    order = "a[new-fuel]",
    stack_size = 200
  },
 {
    type = "recipe-category",
    name = "new-smelting"
  },
{
    type = "recipe",
    name = "new-dust",
    category = "new-smelting",
    energy_required = 3.5,
    ingredients = {{ "new-ore", 1}},
    result = "new-dust"
  },
{
    type = "recipe",
    name = "new-fuel",
    category = "new-smelting",
    energy_required = 5,
    ingredients = {
	  {type="item", name="new-dust", amount=2},
      {type="item", name="coal", amount=1}},
    result = "new-fuel"
  },
  {
    type = "furnace",
    name = "new-furnace",
    icon = "__base__/graphics/icons/electric-furnace.png",
    flags = {"placeable-neutral", "placeable-player", "player-creation"},
    minable = {mining_time = 1, result = "new-furnace"},
    max_health = 150,
    corpse = "big-remnants",
    dying_explosion = "medium-explosion",
    light = {intensity = 1, size = 10},
    resistances =
    {
      {
        type = "fire",
        percent = 80
      }
    },
    collision_box = {{-1.2, -1.2}, {1.2, 1.2}},
    selection_box = {{-1.5, -1.5}, {1.5, 1.5}},
    module_specification =
    {
      module_slots = 2,
      module_info_icon_shift = {0, 0.8}
    },
    allowed_effects = {"consumption", "speed", "productivity", "pollution"},
    crafting_categories = {"new-smelting"},
    result_inventory_size = 1,
    crafting_speed = 2,
    energy_usage = "180kW",
    source_inventory_size = 2,
    energy_source =
    {
      type = "electric",
      usage_priority = "secondary-input",
      emissions = 0.005
    },
    vehicle_impact_sound =  { filename = "__base__/sound/car-metal-impact.ogg", volume = 0.65 },
    working_sound =
    {
      sound =
      {
        filename = "__base__/sound/electric-furnace.ogg",
        volume = 0.7
      },
      apparent_volume = 1.5
    },
    animation =
    {
      filename = "__base__/graphics/entity/electric-furnace/electric-furnace-base.png",
      priority = "high",
      width = 129,
      height = 100,
      frame_count = 1,
      shift = {0.421875, 0}
    },
    working_visualisations =
    {
      {
        animation =
        {
          filename = "__base__/graphics/entity/electric-furnace/electric-furnace-heater.png",
          priority = "high",
          width = 25,
          height = 15,
          frame_count = 12,
          animation_speed = 0.5,
          shift = {0.015625, 0.890625}
        },
        light = {intensity = 0.4, size = 6, shift = {0.0, 1.0}}
      },
      {
        animation =
        {
          filename = "__base__/graphics/entity/electric-furnace/electric-furnace-propeller-1.png",
          priority = "high",
          width = 19,
          height = 13,
          frame_count = 4,
          animation_speed = 0.5,
          shift = {-0.671875, -0.640625}
        }
      },
      {
        animation =
        {
          filename = "__base__/graphics/entity/electric-furnace/electric-furnace-propeller-2.png",
          priority = "high",
          width = 12,
          height = 9,
          frame_count = 4,
          animation_speed = 0.5,
          shift = {0.0625, -1.234375}
        }
      }
    },
    fast_replaceable_group = "furnace"
  },

so basically I have a new ore i have put on the map, this is named 'new-ore', I made a copy of the orignal electric furnace made its crafting_categories to new-smelting and made it take 2 inputs.

I also have two recipes for this furnace, one which turns new-ore into new-dust, this recipe works perfectly fine
the other recipe is meant to take 1 new-dust and 1 coal and turn it into new-fuel.

However when I try to put either coal or new-dust into the furnace it says neither of them can be smelted.
I have also tried making the furnaces crafting_categories = {"new-smelting", "smelting"} which had no effect.

Any help would be awesome thanks,
Kriogenic.

Try replacing the coal in the ingredients list with something else like iron. Test it to see if maybe it's just coal that isn't allowed due to how furnaces work with using coal as power.

You need to make it an assembly machine type instead of a furnace type to take more than one input. Furnaces are hardcoded to just take 1 input, so they can set their recipes automatically

[bobingabout]

I suppose the round-about solution is to make a new furnace entity that is actually an assembling machine, so it can take more custom recipe inputs. The problem is like an assembling machine, you have to set it manually.

Ahhh no worries, thanks for the help. I have made it an assembly machine and all is well
