2D Canvas and Multiplayer Games - WebGL Game Development - page 380

In the second section of the chapter, we introduced you to multiplayer games and
used WebSockets to create a sample spectator client. We used the module Sockets.IO
of Node.js, to implement our multiplayer game.
In this topic, we have trained ourselves in topics such as rendering, animation,
physics engines, collision detection, bone animations, and multiplayer games to
evolve our world in 5000 A.D. Now, we leave it up to you to complete your world
and add components that excite the users of your game.
