NS_Game_Controller

NS_Game_Controller is a game controller software for NSPong.

NSPong is a HTML5 demo game developed on top of ARM Sensinode’s NanoService Platform. The game uses for example RealTimeMultiplayerNodeJS, Box2D and CAAT libraries, which are specifically built for HTML5 multiplayer games with the client/server model.

NSPong is available at https://github.com/NSPong/NSPong.

Demo video is available at https://vimeo.com/95207889.
