Saving/Loading an ItemStack to a NBTTagCompound?

[TLHPoE]

Is there a way to store an ItemStack into an NBTTagCompound with a String key?

[Draco18s]

Yes.

ItemStack has a writeToNBT function.  Just pass in a new NBTTagCompound and you'll get the "stored" version back out.  Then just add that tag to another tag.

 

All container objects do this to save their contents.

[TLHPoE]

Am I doing this right? It doesn't save/load the item stacks at all.

 

 

 

package net.gloriarpg.inventory;

import net.gloriarpg.GloriaRPG;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.ItemStack;
import net.minecraft.nbt.NBTTagCompound;

public class InventoryAccessories implements IInventory
{

public ItemStack[] slots = new ItemStack[7];
public EntityPlayer player;

public InventoryAccessories(EntityPlayer player)
{

	this.player = player;

	this.loadInventoryFromNBT(player);

}

public void loadInventoryFromNBT(EntityPlayer player)
{

	NBTTagCompound nbt = player.getEntityData();

	for(int i = 0;i < slots.length; i++)
	{

		if(slots[i] != null)
		{

			slots[i].writeToNBT(nbt);

		}

	}

}

public void saveInventoryToNBTTagCompound(EntityPlayer player)
{

	NBTTagCompound nbt = player.getEntityData();

	for(int i = 0;i < slots.length; i++)
	{

		if(slots[i] != null)
		{

			slots[i].loadItemStackFromNBT(nbt);

		}

	}

}

@Override
public int getSizeInventory()
{

	return 7;

}

@Override
public ItemStack getStackInSlot(int i)
{

	return slots[i];

}

@Override
public ItemStack decrStackSize(int i, int j)
{

	return slots[i];

}

@Override
public ItemStack getStackInSlotOnClosing(int i)
{

	return slots[i];

}

@Override
public void setInventorySlotContents(int i, ItemStack itemStack)
{

	slots[i] = itemStack;

}

@Override
public String getInvName()
{

	return "Accessories";

}

@Override
public boolean isInvNameLocalized()
{

	return true;

}

@Override
public int getInventoryStackLimit()
{

	return 1;

}

@Override
public void onInventoryChanged()
{

	this.loadInventoryFromNBT(player);
	this.saveInventoryToNBTTagCompound(player);

}

@Override
public boolean isUseableByPlayer(EntityPlayer player)
{

	if(!player.isDead && !player.worldObj.isRemote)
	{

		return true;

	}

	return false;

}

@Override
public void openChest()
{

	//dunno

}

@Override
public void closeChest()
{

	//dunno

}

@Override
public boolean isItemValidForSlot(int i, ItemStack itemStack)
{

	return true;

}

}

Hello,

 

This might help you (it's from a TileEntity):

 

 

NBTTagList taglist = par1nbtTagCompound.getTagList("Inventory");

	for (int i = 0; i < taglist.tagCount(); i++)
	{
		NBTTagCompound tag = (NBTTagCompound)taglist.tagAt(i);

	    byte slot = tag.getByte("Slot");

	    if (slot >= 0 && slot < inventory.length)
	    {
	    	inventory[slot] = ItemStack.loadItemStackFromNBT(tag);
	    }
	}

 

 

And for writing:

 

 

NBTTagList itemlist = new NBTTagList();

	for (int i = 0; i < inventory.length; i++)
	{
		ItemStack itemstack = inventory[i];

	    if (itemstack != null)
	    {
	    	NBTTagCompound tag = new NBTTagCompound();

	        tag.setByte("Slot", (byte)i);
	        itemstack.writeToNBT(tag);
	        itemlist.appendTag(tag);
	    }
	}

For the writing part, how would I write that NBTTagList to the player's NBTTagCompound with a String?

setString?
