sending packets issue

[pitman-87]

Hi guys,

 

I have some issues with sending packets from client to server, it crashes every time and I couldn't find out why.

I looked up the Ironchest code and this one: https://github.com/DarkGuardsman/GSM-Guardsman/blob/master/1.3.1/common/GSM/Network/PacketManager.java

 

my code (client):

public static void sendAddFrequency(int frequency, int x, int y, int z)
{
	ByteArrayOutputStream bytes = new ByteArrayOutputStream();
	DataOutputStream data = new DataOutputStream(bytes);
	int[] dataInt =
	{ 0, frequency, x, y, z };

	try
	{
		for (int i = 0; i < 5; i++)
		{
			data.writeInt(dataInt[i]);
		}

	} catch (IOException e)
	{
	}

	Packet250CustomPayload pkt = new Packet250CustomPayload();
	pkt.channel = "TF2_Teleporter_Chan";
	pkt.data = bytes.toByteArray();
	pkt.length = bytes.size();
	pkt.isChunkDataPacket = true;
	PacketDispatcher.sendPacketToServer(pkt);

}

 

But all I got is this error:

What's a code 503? If you know that, it'll help.

bad idea to use  my code its not 100% stable. Also most of that error has to do with minecraft not downloading the skin for player13. Also where is your code that receives that packet because that might be the error. Currently i'm having issue in my code where the data stream is being read past the actual length of the stream. Which causes an error reading the packet but no crash.

I quess this have nothing todo with the 503-error (it appears everytime on startup), the actual error is this:

2012-08-17 01:57:30 [sEVERE] [ForgeModLoader] A critical server error occured handling a packet, kicking net.minecraft.src.NetServerHandler@6ee7e2ec

 

But I could figured out, after I started client and server seperatly, there was a "real" error-code (NPE).

(I was opening the gui on server too (forgot world.isRemote)).

 

 

For your length-of-stream-problem I'm sending the length too

1. type-id

2. length

3. actual data

 

It's a great help, if you are sending arrays with different lengths.
