I'm trying to add a new player stat (gold), and when I enter my world, put some coins in, leave, and re-enter the same world, my gold gets reset.

 

Am I doing something wrong?

 

PlayerStatsHandler

public class PlayerStatsHandler implements IExtendedEntityProperties
{

public final static String EXT_PROP_NAME = "PlayerStats";

private final EntityPlayer player;

private int gold;

public PlayerStatsHandler(EntityPlayer player)
{

	this.player = player;
	this.gold = 0;

}

@Override
public void saveNBTData(NBTTagCompound compound)
{

	NBTTagCompound properties = new NBTTagCompound();

	properties.setInteger("Gold", this.gold);

	compound.setTag(EXT_PROP_NAME, properties);

}

@Override
public void loadNBTData(NBTTagCompound compound)
{

	NBTTagCompound properties = (NBTTagCompound) compound.getTag(EXT_PROP_NAME);

	this.gold = properties.getInteger("Gold");

}

@Override
public void init(Entity entity, World world)
{



}

public final void syncStatsProperties()
{

	ByteArrayOutputStream bos = new ByteArrayOutputStream(;
	DataOutputStream outputStream = new DataOutputStream(bos);

	try
	{

		outputStream.writeInt(this.gold);

	}
	catch(Exception e)
	{

		e.printStackTrace();

	}

	Packet250CustomPayload packet = new Packet250CustomPayload();
	packet.channel = "tmchannel";
	packet.data = bos.toByteArray();
	packet.length = bos.size();

	Side side = FMLCommonHandler.instance().getEffectiveSide();

	if (side == Side.SERVER) {
		EntityPlayerMP player1 = (EntityPlayerMP) player;
		PacketDispatcher.sendPacketToPlayer(packet, (Player) player1);
	}

}

public void spendGold(int amount)
{

	if(amount <= this.gold)
	{

		this.gold = this.gold - amount;

	}

}

public void addGold(int amount)
{

	this.gold = gold + amount;

}

public void setGold(int amount)
{

	this.gold = amount;

}

public int getGold()
{

	return this.gold;

}

}
