libGDX is a cross platform Java game development framework that provides a single API that works on all supported platforms.
We’ve written a complete tutorial to illustrate how developers can write multiplayer games by integrating AppWarp cloud Java SDK with libGDX. The tutorial uses the excellent single player superjumper sample from libgdx-sample and extends it to a 2 player realtime game.
The complete tutorial is available here with source code and step by step integration guide. AppWarp concepts illustrated are dynamic game rooms, lock properties and our TCP/UDP sendUpdate APIs. Send us a mail on firstname.lastname@example.org with your questions and comments.
