a main menu while playing a map, with "continue" which will continue the map, and "restart" or "retry" button that will restart the map. It can be replacement for pause on space while playing a map. i think thats already requested but im not sure lol

Slider duration is too long on some sliders, probably due to a wrong slider velocity but i could be wrong though.

Server Protocol

We're in a need for a more efficient packet structure than just Bancho v19.
First we thought we maybe go with v20 but then i decided to not go with it.

Basic Information

Most of the traffic is over WebSockets however Spectator and Multiplayer is over UDP.

Protocol packet structure

• WebSockets
  • Packet id: int32
  • Packet data length: leb128
  • Packet Data: Binary
• UDP
  • Authentication Token { random generated 256 bit number } (32 bytes)
  • Packet id: int32
  • Packet data length: leb128
  • Packet Data: Binary

Packet structures

• Packet Structures
  • Authentication
    • Packet id 0x00
      • Client -> Server
        • Protocol Version: uint32
        • Game Version: uint32
        • Game Checksum: leb128 int8 Array
        • Username: leb128 String
        • Password Hash: leb128 int8 Array
          • MD5 due to stable support

        • Timezone: int8
          • UTC+n (N can be negative or positive)
        • Hardware Information

  • Authentication Reply
    • Packet id 0x00
      • Client <- Server
        • Client Id: int32
          • if Negative everything bellow Client Id doesn't have to be send.
          • -1 = User not found
          • -2 = Update required
          • -3 = Game checksum mismatch
          • -4 = Unsupported Protocol (Too new)
        • Server Protocol: uint32

          • Unix timestamp
        • Chat Colour: uint24

  • Pong
    • Packet id 0x03
      • Client <- Server

Make the score on relax a live pp counter while playing. It would make the in-game leaderboard easier to read since it's pp and not score and not going to the top instantly

Random client crashes

The client randomly crashes on startup which is caused by #32.
Discord GameSDK is not thread safe which results it to throw if it's not on the same thread.

the Slider ball is out the slider sometimes.

We're planning on upgrading Bancho protocol from v19 to v20. Please discuss here what we should change or not. One important thing is that v20 is going to run on WebSockets.

as you can see, it may crash the game. or someone just doesnt wants to see everyone seeing him playing qsor and they cant turn this thing off

Approach circles are Asynchronous towards the Hit circle, it should hide the on beat but instead it starts down scaling on beat which indicates that the offset is wrong.

Right now the hover effect does not move like expected. The expected behaviour is that it moves during scrolling, but it's rather "stuck in place" at the moment.

Notice the black bar in the background

Hit object Fade-out and Fade-in aren't handled correctly and can cause a lot of flickering.

the slider begin circle doesn't disappear until the slider has finished slider.

The slider ball starts to Early to move, even before the Hit circle has been fired.
