[1.7.2] Oncrafting Event

[tompinn23]

Hello i am trying to make my mod know when a item(the transmutation orb)is being used in a recipe here is my code for the main class file.

package tompinn23.usefulStuff;

import net.minecraft.block.Block;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.init.Blocks;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraftforge.common.MinecraftForge;
import cpw.mods.fml.common.FMLCommonHandler;
import cpw.mods.fml.common.Mod;
import cpw.mods.fml.common.Mod.EventHandler;
import cpw.mods.fml.common.event.FMLInitializationEvent;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;
import cpw.mods.fml.common.registry.GameRegistry;

@Mod(modid = usefulStuff.modid, version = usefulStuff.version)

public class usefulStuff {
public static final String modid = "UsefulStuff";
public static final String version = "0.1.0 Alpha";
public static Block blockHardQuartz;
public static Item itemHardenedQuartz;
public static Item itemTransOrb;




public static CreativeTabs usefulTab = new CreativeTabs("usefulStuffTab"){
	public Item getTabIconItem() {
		return Items.wooden_pickaxe;
	}

};
@EventHandler
public void preInit(FMLPreInitializationEvent e){
	   
	//Items
	itemHardenedQuartz = new Item().setUnlocalizedName("itemHardenedQuartz").setCreativeTab(usefulTab).setTextureName(modid + ":" + "itemHardenedQuartz");
	GameRegistry.registerItem(itemHardenedQuartz, "itemHardenedQuartz" );
	itemTransOrb = new Item().setUnlocalizedName("itemTransOrb").setCreativeTab(usefulTab).setTextureName(modid + ":" + "itemTransOrb");
	GameRegistry.registerItem(itemTransOrb,"itemTransOrb" );



	//Blocks
	blockHardQuartz = new blockHardQuartz().setBlockName("blockHardQuartz").setCreativeTab(usefulTab).setBlockTextureName(modid + ":" + "blockHardQuartz");
	GameRegistry.registerBlock(blockHardQuartz, "blockHardQuartz");

}

@EventHandler
public void init(FMLInitializationEvent e){
	FMLCommonHandler.instance().bus().register(new  CustomEventListener());
	ItemStack TransStack = new ItemStack(itemTransOrb);
	GameRegistry.addRecipe(new ItemStack(Blocks.cobblestone), "xyy", "y  ","   ", 'x', TransStack, 'y', new ItemStack(Blocks.cobblestone));

}



}

Also my CustomEventhandler

package tompinn23.usefulStuff;

import cpw.mods.fml.common.eventhandler.SubscribeEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent;
import cpw.mods.fml.common.gameevent.PlayerEvent.ItemCraftedEvent;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;

public class CustomEventListener {

@SubscribeEvent
    public void onItemCraftedEvent(PlayerEvent.ItemCraftedEvent event)
    {
	if (event.craftMatrix.getStackInSlot(0) == new ItemStack(usefulStuff.itemTransOrb)) {
		System.out.println("Hay");

	}
    }

}

Please Help

if (event.craftMatrix.getStackInSlot(0) == new ItemStack(usefulStuff.itemTransOrb))

if (event.craftMatrix.getStackInSlot(0).getItem()==usefulStuff.itemTransOrb

Reason: I java the == means that the two things are the same thing, aka lets say I have 2 identical books. Even though book 1 is identical to book 2, book 1 does not == book 2, book 1 only == other references of book 1.

Thank you

 

EDIT: How do you check all slots of the crafting table

and also how do you make the  item stay after crafting but lose durabilty

    public ItemStack getContainerItem(ItemStack itemStack)
    {
        return new ItemStack(this,itemStack.stackSize,itemStack.getItemDamage()+1);
    }
