Hello,

 

I'm trying to figure out how to change a variable in my TileEntity, when a button is pressed and updating all the players about that change. I have 1 number and 2 buttons one for increment the other for decrement. I think, i need packets. So i'm sending a packet when a button is pressed like this:

 

 

@Override
protected void actionPerformed(GuiButton par1GuiButton)
{
	switch (par1GuiButton.id)
	{

	case 0:
		PacketDispatcher.sendPacketToServer(PacketHelper.SendPacket(1, Arrays.asList(1, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord)));
	break;

	case 1:
		PacketDispatcher.sendPacketToServer(PacketHelper.SendPacket(1, Arrays.asList(2, tileentity.xCoord, tileentity.yCoord, tileentity.zCoord)));
	break;

	}
}

 

 

My PacketHelper class is like this:

 

 

public static Packet SendPacket(int id, List<Integer> data)
{
	ByteArrayOutputStream bytearrayoutputstream = new ByteArrayOutputStream(;		
	DataOutputStream dataoutputstream = new DataOutputStream(bytearrayoutputstream);

	try 
	{
	    dataoutputstream.writeInt(id);
	    
	    for (int element : data)
	    {
	    	dataoutputstream.writeInt(element);
	    }
	}

	catch (Exception ex) 
	{
	    ex.printStackTrace();
	}

	Packet250CustomPayload packet = new Packet250CustomPayload();

	packet.channel = "brickcraft";
	packet.data = bytearrayoutputstream.toByteArray();
	packet.length = bytearrayoutputstream.size();

	return packet;
}

 

 

It just creates a packet with a integer list for data storing.

 

Here is my PacketHandler class:

 

 

@Override
public void onPacketData(INetworkManager manager, Packet250CustomPayload packet, Player player) 
{
	DataInputStream datainputstream = new DataInputStream(new ByteArrayInputStream(packet.data));
        
	int id;
	ArrayList<Integer> data = new ArrayList<Integer>();

        try 
        {
            id = datainputstream.readInt();
            
            while (datainputstream.available() > 0)
            {
            	data.add(datainputstream.readInt());
            }
        }
        
        catch (IOException ex)
        {	
            ex.printStackTrace();
            
            return;
        }
        
        HandlePacket(id, data, (EntityPlayer)player);
}

void HandlePacket(int id, ArrayList<Integer> data, EntityPlayer player)
{		
	if (id == 1)
	{
		if (player.worldObj.getBlockTileEntity(data.get(1), data.get(2), data.get(3)) != null)
		{
			PoseblockTileEntity tileentity = (PoseblockTileEntity)player.worldObj.getBlockTileEntity(data.get(1), data.get(2), data.get(3));

			if (data.get(0) == 1)
			{
				tileentity.SetScale(tileentity.scale - 1);
			}

			if (data.get(0) == 2)
			{
				tileentity.SetScale(tileentity.scale + 1);
			}
		}
	}
}

 

 

I checked if a packet is incoming and it is, but the var in the GUI is not updating. I've tried it with world.markBlockForUpdate(x, y, z) but that doesn't worked.

 

 

Thank you in advance!

Hello,

 

Yes, i have overridden that already and tried both

markBlockForUpdate()

and

onInventoryChanged()

but none of them works.

Hello,

 

Problem

SOLVED

it was that

 

if (scale > 0 && scale > 11)
	{
		this.scale = scale;
	}

 

that was wrong, now it works

 

Thank you!
