I need a item to stay in the crafting grid after its used in a recipe but after it is used in one the durabilty goes down each time. I'm pretty sure the code is correct but it wont work. The item stays in the crafting grid but it doesn't take damage!

 

ItemKnife code:

package MoarFoodsItemsClass;

import java.util.Set;

import com.seanomik.moarfoods.MainRegistry;

import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;



public class ItemKnife extends Item {

public ItemKnife() {
	super();
	maxStackSize = 1;
	setMaxDamage(64);
	setNoRepair();
	this.setUnlocalizedName("knife");
	this.setCreativeTab(MainRegistry.moarfoodsTab); 
	this.setContainerItem(this);
}
public boolean doesContainerItemLeaveCraftingGrid(ItemStack itemstack) {

     return false;
}


}

 

The recipe the item in used in:

		GameRegistry.addRecipe(new ItemStack(MoarFoodsItems.tuna, 4), new Object[] { 
			"   ", 
			"k  ", 
			"fp ", 
			'p', MoarFoodsItems.pickle, 'f', Items.cooked_fish, 'k', new ItemStack(MoarFoodsItems.knife, 1, -1)});

Did you set your item to override hasContainerItem and getContainerItem?

Did you set your item to override hasContainerItem and getContainerItem?

How would I use those methods?

You override them in your Item class. getContainerItem is called to provide an ItemStack that should be left behind in the crafting grid (water buckets for example return empty buckets here). hasContainerItem is called to determine if getContainerItem needs to be called.

Thanks both of you it works now!
