Bevy GGRS

Bevy plugin for the GGRS P2P rollback networking library. The plugin creates a custom stage with a separate schedule, which handles correctly advancing the gamestate, including rollbacks. It efficiently handles saving and loading of the gamestate by only snapshotting relevant parts of the world, as defined by the user. It is supposed to work with the latest released version of bevy.

For explanation on how to use it, check the 👉examples!

Live Demonstration (currently offline)

bevy_GGRS has a demo app you can try in the browser! It uses matchbox to facilitate communication between browsers. Try it out with a friend! Just click the link and match with another player! (You can also open the link in two separate windows to play against yourself)
