How can i add a smelting recipe what depends on tool damage? Example: Not damaged iron pickaxe gives 3 iron ingots  when smelted, a bit less than half damaged iron pickaxe gives 2 iron ingots when smelted, a bit more than half damaged iron pickaxe gives 1 iron ingot when smelted and almost fully damaged iron pickaxe can't be smelted.

It's going to junk up you're smelting recipes, but I don't see any other way. You could try `FurnaceRecipes.addSmelting(int itemID, int metadata, ItemStack itemstack, float experience)` as the damage of the pickaxe is pretty much equivalent to its metadata. However, since, for example the diamond pickaxe, has a heck of a lot of durability, you may end up having thousands of recipes...

 

But maybe there's a better way that somebody else knows of.

Maybe make a dedicated recyling station or something.  Then you could make the recipes for it work how you want.

So is metadata how many times the tool has destroyed a block??

Does the FurnaceRecipes.addSmelting work in 1.7.2? If yes, can someone give me an example with iron pickaxe?

So there is no way at all in the latest Forge?

Well, i was going to make recipes for three different damage values.

Yeah, but you said it isn't possible in the current version of Forge?

Oh... I though like that, but didn't think of the fact it would need all in different recipes. Anyways, how can i use FurnaceRecipes.addSmelting? I want to test it anyways, but i couldn't get it work with tools(and i didn't really test it with blocks)...

But how can i use it with metadata?

Found it. Thank you!

Sounds like the most reasonable solution. You could simply derive the furnace and change its mechanics, or replace it in its entirety (maybe not such a good idea...).
