Lack of documentation #6

Open null321-jared opened 7 years ago

On the readme it says "Instructions on how to use the library can be found on the wiki". The wiki is completely empty.

I am very new to RakLib, so I started using this after making very slow progress doing it myself, but I am having trouble interpreting the data that my program gets sent to my Hook.PACKET_RECIEVED HookRunnable. I cannot find a way to match it with any of the MinecraftPE protocol data I have found so far online. I have tried matching the incoming payload up with https://github.com/NiclasOlofsson/MiNET/blob/master/src/MiNET/MiNET/Net/MCPE%20Protocol%20Documentation.md and http://wiki.vg/Pocket_Minecraft_Protocol

I'm trying to get to the stage where I can get the packet ID and use that to decode it using the correct class.

Sorry about the documentation. What is the first byte of the data?

Thank you for the response!

Here is the first byte of every packet the hook gets sent on a basic login: 5 [RakNetServer] INFO JRakLibPlus Server - RakNetServer bound to /0.0.0.0:19132, running on RakNet protocol 7 7999 [RakNetServer] DEBUG JRakLibPlus Server - Session opened from /10.1.10.23 Buffer length: 1404 Unknown packet: 125 (0x7D) Buffer length: 1404 Unknown packet: 85 (0x55) Buffer length: 1404 Unknown packet: 143 (0x8F) Buffer length: 4509 Unknown packet: 125 (0x7D) Buffer length: 297 Unknown packet: 117 (0x75) Buffer length: 1404 Unknown packet: 125 (0x7D) Buffer length: 1404 Unknown packet: 143 (0x8F) 11066 [RakNetServer] DEBUG JRakLibPlus Server - Client latency is 31ms 29944 [RakNetServer] DEBUG JRakLibPlus Server - Session 10.1.10.23:19132 disconnected: client disconnected

And if it matters I am using Minecraft Windows 10 Edition to test it.

@lizardfreak321 I don't recognize any of the ids except for 0x8F, that should be the MCPE container packet. After 0x8F should be the Minecraft packet ID.

I forgot to revert a change resulting in the incorrect offset. Here is the corrected data showing the first three bytes: 5823 [RakNetServer] DEBUG JRakLibPlus Server - Session opened from /10.1.10.23 Packet bytes: 254 (0xFE) 6 (0x06) 0 (0x00) Packet bytes: 103 (0x67) 175 (0xAF) 93 (0x5D) Packet bytes: 90 (0x5A) 83 (0x53) 135 (0x87) Packet bytes: 254 (0xFE) 6 (0x06) 0 (0x00) Packet bytes: 58 (0x3A) 138 (0x8A) 65 (0x41) Packet bytes: 254 (0xFE) 6 (0x06) 0 (0x00) Packet bytes: 58 (0x3A) 138 (0x8A) 65 (0x41) 8886 [RakNetServer] DEBUG JRakLibPlus Server - Client latency is 34ms 11061 [RakNetServer] DEBUG JRakLibPlus Server - Session 10.1.10.23:19132 disconnected: timeout

0xFE is the container I think. What is the mcpe version?
