93+ [ Dango] ([ Github] ( dango-github ) ) is a little multiplayer blob physics sandbox
94+ made by [ @ErnWong ] as a tribute to the [ Dango Daikazoku] [ dango-daikazoku ] from
95+ [ Clannad] . It was made using various libraries from the Rust community,
96+ including the [ Bevy] game engine, the [ NPhysics] physics engine, and the
97+ [ CrystalOrb] networking library. To avoid the costs of running a server, Dango
98+ currently runs the server in the browser and generates a unique URL that lets
99+ other players to join using WebRTC.

139+
140+ [ CrystalOrb] by [ @ErnWong ] is a new networking library that aims to help
141+ fast-paced client-server games synchronize their game state across multiple
142+ clients. Just like [ backroll-rs] and [ GGRS] , each CrystalOrb client predicts
143+ the next game state without waiting for other remote players' inputs to arrive.
144+ Unlike backroll-rs's and GGRS's peer-to-peer approach, CrystalOrb relies on
145+ having a server to send snapshots of the entire game state to each client, and
146+ each client unconditionally rolls-back to that snapshot. Although this may lead
147+ to higher network and memory usage, it means that CrystalOrb clients can join
148+ and leave at any time, and games that cannot guarantee full-determinism can
149+ still work with CrystalOrb.
150+
151+ This library was written as a learning exercise for the author, and as such,
152+ the author warns that this library may not be suitable for serious games.

154+ There is an [ interactive demo] [ crystalorb-demo ] of CrystalOrb (shown in the
155+ above GIF) that features the [ Rapier] physics engine.
