Google Play Games Services in libGDX

Google Play Games Services offers social leaderboards, achievements, and much more (realtime multiplayer, cloud saves, anti-piracy…)

Cross-platform features are deprecated, for new projects it is recommended to use on Android only.

Using open-source libGDX Extension

Google Play Games support for libGDX games on Android and Desktop is provided by gdx-gamesvcs libGDX extension. The extension also provides implementations for other game services (Apple Game Center, GameJolt and others).

Follow the readme and the project’s wiki to integrate GPGS and other game services in your project.

Manual integration in your project

The following article describes the manual integration in your project without using the library.

A Super Jumper based example that makes use of Leaderboards and Achievements.

The project is freely available on GitHub, and a companion tutorial is available here.
