[1.9]Remove Item right after crafting

[Deforner]

Hello Guys,

 

how do I delete an Item right after crafting. I made an IRecipe with my own Item and this should right after i click on the crafting result break randomly. I have a random number, which decides if the Item will break or not, but I don't know how I should delete it. I tried it with TagCompound (here a boolean "broken") and then I used the onUpdate method, but it's not working right after I get it out the crafting table and put it back in. It really should break right after the first click on the Item in the result field. And the best case would be without the boolean. I hope you can help me.

 

yours

Code:

 

 

Crafting Recipe

public class UpgradeRecipe implements IRecipe{

private int stufe = 0;
@Override
public boolean matches(InventoryCrafting inv, World worldIn) {

        List<ItemStack> list1 = Lists.<ItemStack>newArrayList();
        List<ItemStack> list2 = Lists.<ItemStack>newArrayList();
        
	for(int i = 0; i < inv.getSizeInventory(); i++){

		ItemStack itemstack1 = inv.getStackInSlot(i);

		if(itemstack1 != null){

			// Campound cant be null
			if (itemstack1.getItem() instanceof ItemSwordNBT && itemstack1.getTagCompound().getInteger("Stufe") < 10){
				list1.add(itemstack1);
				stufe = itemstack1.getTagCompound().getInteger("Stufe");
			}

			else if (itemstack1.getItem() == Items.diamond){
				list2.add(itemstack1);
			}
			else{
				return false;
			}
		}
	}
	return list1.size() == 1 && list2.size() == 1;
}

@Override
public ItemStack getCraftingResult(InventoryCrafting inv) {
	int random = (int )(Math.random() * 13 + 1);
	random = Math.abs(random - stufe);
	ItemStack stack = new ItemStack(RegisterItem.brokenSword);
	stack.setTagCompound(new NBTTagCompound());
	if(random <= 3){
		stack.getTagCompound().setBoolean("broken", true);
		System.out.println("broken true");
	}
	else{
		stack.getTagCompound().setBoolean("broken", false);
	}
	stack.getTagCompound().setInteger("Stufe", stufe +1);
	return stack;
}

@Override
public int getRecipeSize() {
	return 4;
}

@Override
public ItemStack getRecipeOutput() {
	ItemStack stack = new ItemStack(RegisterItem.brokenSword);
	stack.setTagCompound(new NBTTagCompound());
	stack.getTagCompound().setInteger("Stufe", stufe +1);
	return stack;
}

@Override
public ItemStack[] getRemainingItems(InventoryCrafting inv) {
	ItemStack[] aitemstack = new ItemStack[inv.getSizeInventory()];

        for (int i = 0; i < aitemstack.length; ++i)
        {
            ItemStack itemstack = inv.getStackInSlot(i);
            aitemstack[i] = net.minecraftforge.common.ForgeHooks.getContainerItem(itemstack);
        }

        return aitemstack;
}

}

 

 

 

 

 

ItemSword (brokenSword extends this class)

public class ItemSwordNBT extends ItemSword{

public ItemSwordNBT(ToolMaterial material) {
	super(material);
}
@Override
public void onUpdate(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {
	if (stack.getTagCompound() == null){
		stack.setTagCompound(new NBTTagCompound());
	}
	if(!stack.getTagCompound().hasKey("Stufe")){
		stack.getTagCompound().setInteger("Stufe", 0);
	}
}

@Override
public void addInformation(ItemStack stack, EntityPlayer playerIn, List<String> tooltip, boolean advanced) {
	if (stack.getTagCompound() == null){
		stack.setTagCompound(new NBTTagCompound());
	}
	if(stack.getTagCompound().hasKey("Stufe")){
		tooltip.add("Stufe: " + Integer.toString(stack.getTagCompound().getInteger("Stufe")));
	}
	/*if(stack.getTagCompound().hasKey("broken") && stack.getTagCompound().getBoolean("broken")){
		tooltip.add(1,"Broken!!");
	}*/
