Item not creating NBT Tags

Posted September 21, 201312 yr

I'm currently trying to add NBT tags to my item when it's created, but it never adds the tags nor the information.

package tlhpoe.darkorigins.item;

import java.awt.List;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.util.ChunkCoordinates;
import net.minecraft.world.World;
import tlhpoe.darkorigins.helper.CreativeTabHelper;
import tlhpoe.darkorigins.util.InfoUtil;

public class ItemExpContainer extends ItemBase
{

public ItemExpContainer(int id, String name)
{

	super(id, name);

	setMaxStackSize(1);
	setUnlocalizedName(name);
	setCreativeTab(CreativeTabHelper.items);

}

@Override
public void onCreated(ItemStack itemstack, World world, EntityPlayer player)
{

	itemstack.stackTagCompound = new NBTTagCompound();

	itemstack.stackTagCompound.setFloat("stored", 0.0F);
	itemstack.stackTagCompound.setInteger("mode", 0);

}

public void addInformation(ItemStack itemStack, EntityPlayer player, List list, boolean par4)
{

	if (itemStack.stackTagCompound != null)
	{

		float amount = itemStack.stackTagCompound.getFloat("stored");
		int mode = itemStack.stackTagCompound.getInteger("mode");
		String modeD = "";

		switch(mode)
		{
		case(0):{modeD = "Deposit";}
		case(1):{modeD = "Withdraw";}
		}

		list.add("Exp Stored: " + amount);
		list.add("Mode: " + modeD);

	}

}

@Override
    public ItemStack onItemRightClick(ItemStack itemstack, World world, EntityPlayer player)
    {

	if(player.isSneaking())
	{

		int mode = itemstack.stackTagCompound.getInteger("mode");

		switch(mode)
		{

		case(0):{itemstack.stackTagCompound.setInteger("mode", 1);}
		case(1):{itemstack.stackTagCompound.setInteger("mode", 0);}

		}

	}

	if(!player.isSneaking())
	{

		int mode = itemstack.stackTagCompound.getInteger("mode");
		float xp = itemstack.stackTagCompound.getInteger("stored");

		switch(mode)
		{

		case(0):
		{

			if(player.experienceLevel >= 1)
			{

				player.experienceLevel--;
				itemstack.stackTagCompound.setFloat("stored", xp++);

			}

		}

		case(1):
		{

			if(xp >= 1)
			{

				player.experienceLevel++;
				itemstack.stackTagCompound.setFloat("stored", xp--);

			}

		}

		}

	}

	return itemstack;

    }

}

onCreated is only called when the Item is crafted or smelted, while addInformation is called when you mouse over the item, such as in a Creative Tab, at which point it hasn't been created yet.

You need to check if the NBT tag is null and create a new one if so in any method that may need to access it.

I added null checks, and if it was null, I created the NBT. It crashes on Right Click (I craft it and then right click it, still not information)

The error log says it all: can't cast NBTTagFloat as NBTTagInt.

Do you see:

float xp = itemStack.stackTagCompound.getInteger("stored");

It doesn't crash or give off errors any more, but it never displays the information.

The breaks fixed the depositing/withdrawing part. Information still doesn't display though. :I

Perhaps try adding '@Override' annotation above your addInformation method?

Might be an error in the tags.

Store the String tags as static final fields and use them instead.

Oh, found the problem. I was using the wrong parameters for the addInformation method.

I don't think that annotation means what you think it means.

--Inigo Montoya

(Hint: That particular annotation only has an effect inside your IDE to trigger additional error checking; leaving it off has no effect once the program is compiled)

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

Adding it helped him figure out he had the incorrect method signature. I'd say that's a pretty useful purpose even if at compile time it doesn't change the outcome.

Hello,

BTW, the onCreate wasn't being called for me, when i shift-clicked the item out of the crafting table.

Processor failed, invalid outputs

Sorry for necro, but this is one of the first search results for this issue. Possible cause is Forge checking for zlib (the expected hash) and not accepting zlib-ng (the actual hash):

https://github.com/PrismLauncher/ForgeWrapper/issues/3

One possible workaround (aside from swapping zlib-ng for zlib which might cause other problems on your system) would be to use the prism flatpak.
