[Solved][2.0.43] How can I set the icon for a recipe?

I am creating a new object with its own icon. The new object is used in two recipes.

What I am trying to do is that each recipe has a different icon.

The following code is functional and the image shows the problem.

Code: Select all

---------------------------------------------------------------------------------------------------
---> data.lua <---
---------------------------------------------------------------------------------------------------

local function DeepCopy(value)
    if type(value) ~= "table" then return value end
    local Output = {}
    for Key, Value in pairs(value) do
        Output[Key] = DeepCopy(Value)
    end
    return Output
end

--- --- --- --- --- --- --- --- --- --- --- --- --- ---

local StackSize   = 500
local Ingredients = 1000

local ArrowU      = { icon = data.raw["virtual-signal"]["up-arrow"].icon, scale = 0.30 }
local ArrowD      = { icon = data.raw["virtual-signal"]["down-arrow"].icon, scale = 0.30 }
local Item        = {}

local item_name   = "solid-fuel"

local Prefix      = "zzzYAIM904-"

--- --- --- --- --- --- --- --- --- --- --- --- --- ---

local item        = data.raw.item[item_name]

local Properties  = {}
table.insert(Properties, "localised_name")
table.insert(Properties, "inventory_move_sound")
table.insert(Properties, "pick_sound")
table.insert(Properties, "drop_sound")
table.insert(Properties, "subgroup")
table.insert(Properties, "order")
table.insert(Properties, "icons")
for _, key in pairs(Properties) do
    Item[key] = DeepCopy(item[key])
end

Item.name                  = Prefix .. item.name
Item.type                  = "item"
Item.stack_size            = StackSize

Item.localised_description = { "" }
table.insert(Item.localised_description, Ingredients .. " ")
table.insert(Item.localised_description, "[item=" .. item.name .. "] ")

table.insert(Item.icons, ArrowU)

data:extend({ Item })

--- --- --- --- --- --- --- --- --- --- --- --- --- ---

local RecipeD                     = {}
RecipeD.type                      = "recipe"

RecipeD.ingredients               = { { type = "item", name = item.name, amount = Ingredients } }
RecipeD.subgroup                  = item.subgroup
RecipeD.order                     = item.order

table.insert(RecipeD.icons, ArrowD)
data:extend({ RecipeD })

RecipeU.subgroup            = item.subgroup

The recipe has a different icon than the object icon in the code, but the recipe icon is being ignored and the object icon is being used. The object icon is also being used by the second recipe. This results in two recipes with the same icon even though the code says otherwise.
How can I change this?

What I mean is, what is the point of defining the icons of the recipes if in the end they will be ignored and another one will be used.

Try giving the recipe and item a different localised_name.

I changed the localised_name in the following code but it is the same result.

How about a different "name"?

Changing the names separates the recipes from the object.

It's not what I expected but it might work for me.
Thank you.
I still find it strange that the recipe ignores its own icons in favour of the result icons.
