[1.12] Oredict Recipe Output

[Draco18s]

I  used to register some recipes that take an input supplied by my mod (the item always exists) and make the output the first item of a named type pulled from the ore dictionary.

 

These recipes are TinyDust  -> LargeDust conversions and I only bothered supplying large dusts for ores that their own mods did not supply a large dust for (e.g. IC2 supplies tin and copper, so my mod didn't need to).

 

Now that 1.12 has rolled around with its JSON recipes, how can I replicate this feature?

You'll need your own recipe class and factory for this.

 

In the factory, read the ingredients, shape (if it's shaped) and output ore name and create the recipe. In the factory or recipe constructor, use OreDictionary.getOres(String) to get the list of items for that name and store it in a field of the recipe.

 

Implement IRecipe#getRecipeOutput and IRecipe#getCraftingResult to return either the first item in the item list if there is one or ItemStack.EMPTY if it's empty. You might want to cache this in case the order of the list changes (though this shouldn't happen unless a mod messes with the Ore Dictionary internals).

Cool, thanks Choonster.

Shame the oredict isn't ready / populated when recipes get parsed or I could pass the oredict value straight to the constructor and skip over the getRecipeOutput and getCraftingResult overrides entirely.
