HOOOWWWW bout you go and look at where that leads to before commenting. There is no "addSmelting(int, int, ItemStack)" in net.minecraft.src.ModLoader. Only "addSmelting(int, ItemStack, Float)" and one without the float (for xp). And if you look at what is under those methods, it says "GameRegistry.addSmelting(input, output, experience);" and if you look at whats in THAT class, it leads to the one i mentioned.....and so, please look into this better next time
