Highly configurable and extensible implementationofRollback Netcode with full asynchronous IO.

Heavily inspired byGGPO.

Traditional techniques account for network transmission time by adding delay to a players input, resulting in asluggish, laggy game-feel. Rollback networking uses input prediction and speculative execution to send player inputs tothe game immediately, providing the illusion of a zero-latency network. Using rollback, the same timings, reactions,visual and audio queues, and muscle memory your players build up playing offline will translate directlyonline.Backdash is designed to make incorporating rollback networking (aka.RollbackNetcode) into new and existing games as easy as possible.
