Hello,

 

I ran into a strange packet issue: When I send a packet to update the server for an ItemStack.TagCompount changes, it seems can't upadate nothing, even if i use the ItemStack or TagCompound object:

 

Packet:

public class PacketPlayerStats implements IMessage
{
  ItemStack drill;
  NBTTagCompound stackCompound;
  
  public PacketPlayerStats()
  {
  }

  public PacketPlayerStats(ItemStack item, NBTTagCompound compound)
  {
    this.drill = item;
    this.stackCompound = compound;
  }

  @Override
  public void fromBytes(ByteBuf buf)
  {
       this.drill = ByteBufUtils.readItemStack(buf);
       this.stackCompound = ByteBufUtils.readTag(buf);
  }
  
  @Override
  public void toBytes(ByteBuf buf)
  {
       ByteBufUtils.writeItemStack(buf, this.drill);
       ByteBufUtils.writeTag(buf, this.stackCompound);
  }
  
  public static class Handler implements IMessageHandler<PacketPlayerStats, IMessage> {
      
      @Override
      public IMessage onMessage(PacketPlayerStats message, MessageContext ctx) {
    EntityPlayer player = NetUtils.getPlayerFromContext(ctx);
    
        message.drill.stackTagCompound.setInteger("scan", (int)message.value);
	OR
        message.stackCompound.setInteger("scan", (int)message.value);
    
    return null;
  }
  }
}

 

Function:

  @Override
  public ItemStack onItemRightClick(ItemStack itemStack, World world, EntityPlayer player)
  {
      if (world.isRemote)
      {
	      if (Keyboard.isKeyDown(Keyboard.KEY_LCONTROL) || Keyboard.isKeyDown(Keyboard.KEY_RCONTROL))
	      {

	  				if(!itemStack.hasTagCompound()) itemStack.setTagCompound(new NBTTagCompound());
	  				int scanMode = itemStack.stackTagCompound.getInteger("scan");

	  				if (scanMode == 0) {
	  					scanMode = 1;
	  				} else if (scanMode == 1) {
	  					scanMode = 2;
	  				} else if (scanMode == 2) {
	  					scanMode = 3;
	  				} else if (scanMode == 3) {
	  					scanMode = 0;
	  				}
	  				
	  				itemStack.stackTagCompound.setInteger("scan", scanMode);

	  				PacketDispatcher.sendToServer(new PacketPlayerStats(itemStack, itemStack.stackTagCompound));

	      }
	}
   }

You aren't doing anything in the onMessage method...

Since the message.drill is just a part of 'message', not the real ItemStack instance player is holding, nothing will happen.

 

You should get the drill item form the Player.

& there is no need to send the 'drill' ItemStack.
