In this mobile world, games aren’t just for the hardcore MMOG fan anymore, they’re for everyone; in fact, three out of four people with an Android phone or tablet play games. If you’re a game developer, Google has a host of tools available for you to help take your game to the next level, including Google Play game services, which let’s you leverage Google’s strength in mobile and cloud services so you can focus on building compelling game experiences for your users. Today, we’re adding more tools to your gaming toolbox, like the open sourcing of a 2D physics library, as well as new features to the Google Play game services offering, like a plug-in for Unity.
LiquidFun, a rigid-body physics library with fluid simulation
First, we are announcing the open-source release of LiquidFun, a new C++ 2D physics library that makes it easier for developers to add realistic physics to their games.
Based on Box2D, LiquidFun features particle-based fluid simulation. Game developers can use it for new game mechanics and add realistic physics to game play. Designers can use the library to create beautiful fluid interactive experiences.
The video clip below shows a circular body falling into a viscous fluid using LiquidFun.
The LiquidFun library is written in C++, so any platform that has a C++ compiler can benefit from it. To help with this, we have provided a method to build the LiquidFun library, example applications, and unit tests for Android, Linux, OSX and Windows.
We’re looking forward to seeing what you’ll do with LiquidFun and we want to hear from you about how we can make this even better! Download the latest release from our LiquidFun project page on GitHub and join our discussion list!
Google Play Games plug-in for Unity
If you are a game developer using Unity, the cross-platform game engine from Unity Technologies, you can now more easily integrate game services using a new Google Play Games plug-in for Unity. This initial version of the plug-in supports sign-in, achievements, leaderboards and cloud save on Android and iOS. You can download the plug-in from the Play Games project page on GitHub, along with documentation and sample code.
New categories for games in Google Play
New game categories are coming to the Play Store in February 2014, such as Simulation, Role Playing, and Educational! Developers can now use the Google Play Developer Console to choose a new category for their apps if the Application Type is “Games”. The New Category field in the Store Listing will set the future category for your game. This will not change the category of your game on Google Play until the new categories go live in February 2014.
