[Solved]Trying to make an item take damage when you craft with it

[shmcrae]

I'm trying to make a grinder where you put a grinder and one ore and it returns 2 dust. It works to some extent but when i put a whole stack in, it takes the whole stack and only returns 2 dust. Here's my code:

 

Recipe: GameRegistry.addRecipe(new ItemStack (CopperDust, 2), new Object [] {

"GO ", "  ", "  ", 'G', (new ItemStack(AlchemyMain.Grinder, 1, Short.MAX_VALUE)), 'O', AlchemyMain.CopperOre

});

 

 

Crafting Handler: public class AlchemyCraftingHandler implements ICraftingHandler

{

@Override

public void onCrafting(EntityPlayer player, ItemStack item, IInventory craftMatrix)

{

for(int i = 0 ; i < craftMatrix.getSizeInventory(); i++)

{

if(craftMatrix.getStackInSlot(i) != null)

{

ItemStack j = craftMatrix.getStackInSlotOnClosing(i);

 

if(j.getItem() != null && j.getItem() == AlchemyMain.Grinder)

{

ItemStack k = new ItemStack(AlchemyMain.Grinder, 2, (j.getItemDamage() + 1));

 

if(k.getItemDamage() >= k.getMaxDamage())

{

k.stackSize--;

}

craftMatrix.setInventorySlotContents(i, k);

}

}

}

}

 

@Override

public void onSmelting(EntityPlayer player, ItemStack item)

{

 

}

}

 

Grinder Class: public class ItemGrinder extends Item

{

private ItemStack emptyItem = null;

public ItemGrinder(int par1, EnumToolMaterial toolGrinder)

{

super(par1);

maxStackSize = 1;

this.setMaxDamage(1000);

this.setCreativeTab(AlchemyMain.TabAlchemy);

}

public void registerIcons(IconRegister iconRegister)

{

itemIcon = iconRegister.registerIcon("alchemy:Grinder");

}

}

 

 

If you need anything else ill post it. Thanks

Ah, pls use spoiler and code tags.

I will have a look at it as soon as I am back at my pc.

 

Ok:

 

You loop through the crafting matrix to find your grinder. Good

 

You get your grinder. Good

 

You set the damage and place it in the correct slot. Good

 

But you never check how many items are crafted. You have to check the output stack size and than add it to the damage from j.

Ok, that works alright now, but is there a way to leave the grinder in the crafting table and not having it go back to my inventory?

 

btw i used diesieben07's method so i got rid of my crafting handler
