[1.7.2] LivingDeath event crash


Jdb100

Recommended Posts

I have been working on getting the id of the mob but for some reason when i check to see if the item is null or my item it crashes.

 

@SubscribeEvent
public void OnEntityDeath(LivingDeathEvent event)
{
	if(event.source.getSourceOfDamage() instanceof EntityPlayer)
	{
		EntityPlayer player = (EntityPlayer) event.source.getSourceOfDamage();
		int size = player.inventory.mainInventory.length;
		for(int i = 0; i < size; i++)
		{
			ItemStack itemStack = player.inventory.mainInventory[i];
			if(itemStack.getItem() != null)
			{
				if(itemStack.getItem() instanceof ItemSoulJar)
				{
					//if(rand.nextInt(50) == 1)
						if(itemStack.stackTagCompound == null)
						{
							itemStack.setTagCompound(new NBTTagCompound());
							itemStack.stackTagCompound.setInteger("Entity Id", event.entityLiving.getEntityId());
						}
				}
			}
		}
	}
}
