Good GameMaker Rollback
A downloadable asset pack
GGMR is a rollback netcode library for GameMaker originally used in Platform Fighter Engine. It is peer-to-peer and works on any export that can use the UDP packet sending functions. Cross-play between exports may not work due to rounding errors on different devices.
GGMR was written before the official GameMaker rollback features, and allows for more customization since it is not integrated into the engine.
The function documentation for GGMR can be viewed in the PFE documentation. There are no written tutorials or example projects as of now (besides PFE).
