UserStats

The following structure is used until today:

Size	Datatype	Description
4	sInt	UserId
	StatusUpdate	Status
8	sLongLong	Ranked Score
4	float	Accuracy
4	sInt	Play Count
8	sLongLong	Total Score
4	sInt	Rank
2	sShort	PP

In versions b20120725 and lower, the pp is not present anymore:

Size	Datatype	Description
4	sInt	UserId
	StatusUpdate	Status
8	sLongLong	Ranked Score
4	float	Accuracy
4	sInt	Play Count
8	sLongLong	Total Score
4	sInt	Rank

As explained in this document, the user stats changed a lot on how they work in versions b1700 and below. Here we need to introduce a new enum, called "Completeness", which determines how much data to read:

Name	Value
StatusOnly	0
Statistics	1
Full	2

If the "Completenes" is set to StatusOnly, the following information is sent:

Size	Datatype	Description
4	sInt	UserId
1	Completeness
	StatusUpdate	Status

If it's set to Statistics, it will contain this:

Size	Datatype	Description
4	sInt	UserId
1	Completeness
	StatusUpdate	Status
8	sLong	Ranked Score
4	float	Accuracy
4	sInt	Playcount
8	sLong	Total Score
4	sInt	Rank

And lastly, if it's set to Full:

Size	Datatype	Description
4	sInt	UserId
1	Completeness
	StatusUpdate	Status
8	sLong	Ranked Score
4	float	Accuracy
4	sInt	Playcount
8	sLong	Total Score
4	sInt	Rank
	String	Username
	String	Avatar Filename
1	uChar	Timezone + 24
	String	City
1	uChar	Permissions
4	float	Longitude
4	float	Latitude

Note

The city should be left empty, if the Display City Location is set to false in the Client Info.

In b338, the "Rank" datatype was changed:

Size	Datatype	Description
4	sInt	UserId
1	Completeness
	StatusUpdate	Status
8	sLong	Ranked Score
4	float	Accuracy
4	sInt	Playcount
8	sLong	Total Score
2	uShort	Rank

In b337, the "Completeness" is not present anymore. Instead there is a boolean, called "newstats", that determines if there are... well... new stats.

Here is an example when the boolean is false:

Size	Datatype	Description
4	sInt	UserId
1	bool	Newstats (false)
	StatusUpdate	Status

And here is the structure, when it's set to true:

Size	Datatype	Description
4	sInt	UserId
1	bool	Newstats (true)
	String	Username
8	sLong	Ranked Score
4	float	Accuracy
4	sInt	Playcount
8	sLong	Total Score
4	sInt	Rank
	String	Avatar Filename
1	uChar	Timezone + 24
	String	City
	StatusUpdate	Status
