I can't seem to figure out how to make my enchantment fire when it should.  It's a sword enchantment, so it should fire when the player attacks something.  I can make things happen when the player attacks things, but I can't figure out how to only fire when the player is using a sword with the proper enchantment.  I've got it at this point doing things only when the player has a sword in hand. How can I restrict this further to only do things when the sword is properly enchanted? 

 

I'm probably approaching this from the entire wrong direction.

 

Here's my event hook

package quyzi.mod.common;

import net.minecraft.client.Minecraft;
import net.minecraft.entity.EntityLiving;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagList;
import net.minecraft.util.DamageSource;
import net.minecraft.world.World;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.living.LivingAttackEvent;
import quyzi.mod.enchants

public class EventHook
{
  
  @ForgeSubscribe
  public void entityAttacked(LivingAttackEvent event)
  {
    EntityLiving attacked = event.entityLiving;
    DamageSource attacker = event.source;
    
    if ( attacker.getEntity() instanceof EntityPlayer )
    {
      EntityPlayer player = Minecraft.getMinecraft().thePlayer;
      ItemStack itemHeld = player.inventory.getCurrentItem();
      
      if( swordIDS.contains(itemHeld.itemID) )
      {
        // Player attacks ~ with sword
        NBTTagList enchlist = itemHeld.getEnchantmentTagList();
        for(int i = 0; i < enchlist.tagCount(); i++)
        {
          System.out.println(enchlist.tagAt(i));
        }
      }
      else if( bowIDS.contains(itemHeld.itemID) )
      {
        // Player attacks ~ with bow
      }
    }
  }

}

 

And it's registered in init:

  @Init
  public void init(FMLInitializationEvent event)
  {
    enchantShocking = new EnchantShocking(enchID);
    LanguageRegistry.instance().addStringLocalization("enchantment.damage.Shocking", "Shocking");
    
    MinecraftForge.EVENT_BUS.register(new EventHook());
  }

 

        NBTTagList enchlist = itemHeld.getEnchantmentTagList();
        for(int i = 0; i < enchlist.tagCount(); i++)
        {
          System.out.println(enchlist.tagAt(i));
        }

 

In this, you just have to add a check if enchlist.tagAt(I) is equal to your custom enchant

 

        NBTTagList enchlist = itemHeld.getEnchantmentTagList();
        for(int i = 0; i < enchlist.tagCount(); i++)
        {
          if (enchlist.tagAt(i).getInteger("id") == MainModFile.enchantShocking.enchID) {
            //Do what you want your enchant to do, probably shock someone.
          }
          System.out.println(enchlist.tagAt(i));
        }

What personally like to use is this

int strikeLvl = EnchantmentHelper.getEnchantmentLevel(
		        WeaponsCore.enchStrike.effectId,
		        player.getCurrentEquippedItem());

if (strikeLvl > 0)
		{

			code here...
		}

 

There you also get access to the enchantment level, but that's really just a personal preference.

I did not know about the enchantment helper. Thank you!
