What It Is

Highly concurrent multiplayer focused game engine, with an emphasis on realtime streamable asset management.

Goals

  • Fast: Logic should be quick and efficient, as well as highly concurrent and/or parallel. Async is used where it makes sense, e.g. for IO operations.
  • Modular: Most subsystems should have swappable implementations to fit different technologies and/or platforms.
  • Multiplayer-Orientated: This engine is designed to be used for multiplayer games, and its design should reflect that.

What It Isn't

An all-purpose game engine. gTether isn't designed to cater to any situation, but is rather intended for a specific category of game. gTether is also not designed to be a "simple" game engine. While we avoid complexity for the sake of complexity, we will prioritize function over ease-of-use.

If a simple all-purpose game engine is what you are looking for, you may be interested in Bevy instead.

Getting Started

Take a look at the examples, especially the Reversi example.
