In your recipe you need to add one of these:
category = "smelting", - will melt in the furnace,
category = "crafting", - assembling-machine or hands, should be like this:
data:extend({
{
type = "recipe",
name = "coal",
energy_required = 3,
category = "smelting",
enabled = true,
ingredients = {{"wood", 5}},
result = "coal"
}
})
--or so
data:extend({
{
type = "recipe",
name = "coal",
energy_required = 3,
category = "crafting",
enabled = true,
ingredients = {{"wood", 5}},
result = "coal"
}
})
Because of the difficulty of translation, I did not understand what exactly you wanted.
