C++ Peer To Peer Game Networking SDK

GekkoNet

C++ Peer To Peer Game Networking SDK

Consider this project unstable until ive gone through most of the work in progress items.

Why?

I built this because I wanted a SDK to plug into my C++ projects, in the past I have created a wrapper around GGRS for C++ but after having to deal with Rust FFI I decided to build a native alternative instead to more easily fit my projects. GekkoNet is heavily inspired by the GGPO Rust reimplementation GGRS.

Why not use GGPO?

I am personally not a big fan of the callback based approach of GGPO hence why I am more of fond of how GGRS handles its control flow. And I might be addicted to reinventing the wheel 😅

Project Goals

Done

• Local/Couch Sessions
  • Per Player Input Delay Settings
• Online Sessions
  • Local Player Input Delay Settings
  • Remote Player Input Prediction Settings
• Spectator Sessions
  • Spectator Delay Settings.
  • The added ability to spectate spectators. This might be handy if you have a seperate spectating service which propegates the inputs to more spectators.
• Limited Saving
  • Save the gamestate less often which might help games where saving the game is expensive. This is at the cost of more iterations advancing the gamestate during rollback.
• Abstracted socket manager. Plug GekkoNet into existing networking solutions such as Steamworks or default sockets by inheriting and overriding the socket manager.
• Event System for notifications for eg. specific players being done with syncing.
• Desync Detection (Only when limited saving is disabled for now)

Work in progress

• Network Statistics
• Joining a session that's already in progress as a spectator (and maybe as a player later)
• Add Cmake for building.

Maybe Later

• Replays
• Commission an artist to create a logo for GekkoNet
