Server Packets

Synopsis

Certain packets sent by the server contain information about the game. These are sent as rarely as possible (only when needed, possibly to reduce packet size or to prevent us from reading it). This page contains information about certain chunks of these packets.

Leaderboard

This packet appears to be sent by the server to the client when a "violent" change in the leaderboard occurs (e.g. someone on the leaderboard is killed).

Basic structure of leadership packet is as follows (useful for capturing the leaderboard names as well as their approximate scores).

Note: You must scan the packet for a value of x that satisfies the given conditions, and y is the location of the last \0 when you are done parsing the names.

Offset	Size(s)	Value Type	Explanation or Function
+0	1 byte	uint8	Either 0 or 2
x	1 byte	uint8	Value at this offset must be 11
x+8	1 byte	uint8	Value at this offset must be 17
x+9...y	varies	string[10]	Ten null-terminated strings in a row
y+7...	4 bytes each	float32[10]	Ten scores in a row

A sample leaderboard packet that also contains some special characters (e.g. emoji, accents, etc.) is here for your reference:

x	1 byte	uint8	Value at this offset must be 6
x+1	varies	string	Name of entity that killed player
