List of supported packets

Packet support

This is a complete list of all the packets in the Minecraft Protocol, and their status in Krypton (how much support they have)
Feel free to let me know if I missed anything!

Status meanings:

✔️ = Fully supported - everything, or mostly everything, is supported for this packet
🟠 = Partially supported - parts of this packet are supported, but others aren't
❌ = Not supported - nothing in this packet is supported

Handshake

Assume these are all serverbound, there are no clientbound packets in this state

Note: the packets "Set Difficulty", "Lock Difficulty" and "Update View Distance" have been omitted from this list, as they are single player only and will never be supported in Krypton.

In addition, the following packets will not be implemented in Krypton as they are not used by the Notchian client/server (unless there becomes a want/need to use them):

• Ping (PLAY state)
• Pong (PLAY state, response to Ping)
• End Combat Event
• Enter Combat Event

I realise that this isn't always the best metric for tracking overall progress, as most of the backend work actually isn't networking, but internal processing (ticking). Therefore, I need to come up with a better way of tracking progress than this.
