Current SynthNet Experimentation Client Upcoming SynthNet Encode/Decode Testing
Below is the source to BerryCraft. Most of the project is pretty trivial – however, MCIO.java (MineCraft IO) contains a class capable of full communication with a Minecraft server, correctly sending/receiving all Minecraft packet types as documented here. BerryCraft itself only implements chat/time functionality (and logins of course), but the MCIO could be used to build out any Minecraft functionality (player positioning, mob spawning and attributes, inventory, etc).
If you do end up using MCIO, let me know, I’d love to see the results!
