How would I go about making an autosmelting pickaxe?


Recommended Posts

Hi. I've been working on a mod the past few weeks and I'm trying to create an autosmelting pickaxe. So far I've managed to make it drop both the ore and the ingot the first time you do it after logging in but then it only drops the ore. Any ideas? Here's my code so far:

public boolean onBlockDestroyed(ItemStack itemStack, World world, int par1, int par2, int par3, int par4, EntityLivingBase entityLivingBase) {

	Block brokenBlock = Block.blocksList[world.getBlockId(par2, par3, par4)];
	int meta = world.getBlockMetadata(par2, par3, par4);

	if (brokenBlock != null) {

		ItemStack result = FurnaceRecipes.smelting().getSmeltingResult(new ItemStack(brokenBlock, 1, meta));

		if (result != null) {

			EntityItem drop = new EntityItem(world, par2, par3, par4, result);
			return false;



	return true;

The issue is the following: FurnaceRecipes#getSmeltingResult returns an ItemStack that is stored in the internal recipe list. You take that exact ItemStack and put it into an EntityItem. When that EntityItem is picked up, it passes that ItemStack (which is still the same instance from the recipe list!) to the player inventory where it get's modified. Because it is still in the FurnaceRecipes list that basically modifies the furnace recipe!

What you need to do is pass a copy of the ItemStack to the EntityItem (ItemStack.copy()).
