Help Consuming Items When the Durability of the Held Item Reaches 0. Minecraft 1.12.2

[NathanMndz1]

Hello, i need some help/suggestions on implementing a method. I have created a class that allows the player to summon ender pearls via a staff. I want to make it so when the items durability reaches 0, instead of the item breaking, the class searches the players inventory for ender pearls if it finds some it then removes a certain amount and it replenishes the objects durability. Any suggestions?  Below is the staff class.

 

package com.aww_man.Teleportation.items;

import com.aww_man.Teleportation.Main;
import com.aww_man.Teleportation.init.ModItems;
import com.aww_man.Teleportation.util.IHasModel;
import com.mojang.realmsclient.dto.PlayerInfo;

import net.minecraft.client.Minecraft;
import net.minecraft.entity.item.EntityEnderPearl;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;

import net.minecraft.util.EnumActionResult;
import net.minecraft.util.EnumHand;
import net.minecraft.util.math.Vec3d;
import net.minecraft.world.World;
import net.minecraftforge.client.event.sound.PlaySoundEvent;

public class VoidStaff extends Item implements IHasModel{
    public VoidStaff(String name) {
        setUnlocalizedName(name);
        setRegistryName(name);
        setCreativeTab(Main.modtabs);
        ModItems.ITEMS.add(this);
        setMaxDamage(100);
        setMaxStackSize(1);
    }
    @Override
    public ActionResult<ItemStack> onItemRightClick(World worldIn, EntityPlayer playerIn, EnumHand handIn) {
        ItemStack enderpearls = playerIn.getHeldItemOffhand();
        ItemStack item = playerIn.getHeldItem(handIn);
            Vec3d Look = playerIn.getLookVec();
            item.damageItem(5, playerIn);
            EntityEnderPearl enderpearl = new  EntityEnderPearl(worldIn, playerIn);
            enderpearl.setPosition(playerIn.posX+Look.x*30d, playerIn.posY+Look.y*30d, playerIn.posZ+Look.z*30d);
            worldIn.spawnEntity(enderpearl);
            playerIn.getCooldownTracker().setCooldown(this, 60);
            return new ActionResult<ItemStack>(EnumActionResult.SUCCESS,item);
        
    }
    @Override
    public void registerModels() {
        Main.proxy.registerItemRender(this,0,"inventory");
        
    }
    
}

For the damage, you can check/set the ItemStack's damage with ItemStack#getDamage() and ItemStack#setDamage().

For the inventory searching, you can get the player's inventory through the EntityPlayer object, use that to check for the ender pearls, and get an ItemStack of them to interact with and change.
