I am trying to make a mod that lets you throw nether stars like ninja shurikens. For that, I am trying to check a player's held item, but whenever I do, my game crashes. My code is as follows:

 

package org.devoxx4kids.forge.mods;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Items;
import net.minecraft.util.ChatComponentText;
import net.minecraftforge.event.entity.player.PlayerInteractEvent;
import net.minecraftforge.event.entity.player.PlayerInteractEvent.Action;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class NinjaSkills {

@SubscribeEvent
public void throwShuriken(PlayerInteractEvent event){
	if (event.action != Action.RIGHT_CLICK_AIR && event.action != Action.RIGHT_CLICK_BLOCK) {
		return;
	}

	if (event.entityPlayer.getItemInUse().getItem() != Items.nether_star) {
		return;
	}

	event.entityPlayer.addChatMessage(new ChatComponentText("You threw a shuriken!"));
}
}

 

I have tried checking a player's held item in MANY other mods, but it never works.

Never mind, I figured it out. Apparently, the method

getItemInUse()

made me crash while the method

getHeldItem()

didn't.
