[Not yet complete, wait until I have time to finish this thought ^_^ @ 2020-May-11 19:11 UTC+8]
To enhance the PacketEncoder efficiency and to provide packets sync to web packet parser
(pktParser), I have the following ideas:

1. Rewrite PacketEncoder with memory stream
   • MemoryStream (ref: stackoverflow)
   • Add functions to append (/build/concat) packet to MemoryStream
2. Write parser to parse packets from PacketEncoder from c# -> to WebPacketParser
   (additional info can be written using comment after each data in packet)
   Longer packet header must be placed at the beginning of the key-value database
   (Detail will be listed on 2nd floor of this thread)

Additional enhancement for parser:

• Identify the format string format [See: Issues 17]
• Auto gen _pkt.js after git push

Current findings:
|: FS title, col1 ->> not sure
^: NPC name2, col2 ->> not sure
@: NPC name, col1 ->> not sure, NPC blue name?

Confirmed:y.

$: direct value (can be an int, can be a string)
||||: name newline

The current packet will crash the other clients and the packet itself also seems wrong.

As stated in title.

Task List

• Confirm packet documenting format
• Rewrite Signature Builder for the new format and with c#.net core
• Update Packet Parser for JSON support

Packets that we need to confirm

Packets in this section are needed to re-confirm the structure
Format:

[<packet delimeter>]: <desc of the packet>
[additional desc of the packet, e.g.: where it can be found, how to trigger this packet]

• [b9a2??]: Update Player Act?
  • Trigger: SHIFT + Left Click (known as updating facing)
  • sometimes it works, maybe need some kind of combination?
• ... TODO: add more ...

Packets that we want

Packets in this section are needed to capture from the official server
Format:
<desc of the packet ..., e.g.: where it can be found, how to trigger this packet>

• Teacher NPC
  • Show teacher list's GUI
  • Teacher info on the teacher GUI (list item)
• Pet NPC
  • Show pet warehouse GUI
  • Show pet training GUI
  • Info of the training pet on the training GUI

As stated, the Player.act is not the real act with PacketEncoder.playerAct. Instead, seems Player.act is confused with PacketEncoder.playerUpdateState & PacketEncoder.spawnHero. (?)

Need to figure out which is which.
