    LiquidFun Version 1.1.0

    Welcome to LiquidFun!

    LiquidFun is a 2D physics engine for games. Go to our landing page to browse our documentation and see some examples.

    LiquidFun is an extension of Box2D. It adds a particle based fluid and soft body simulation to the rigid body functionality of Box2D. LiquidFun can be built for many different systems, including Android, iOS, Windows, OS X, Linux, and JavaScript. Please see Box2D/Documentation/Building/ for details.

    Discuss LiquidFun with other developers and users on the LiquidFun Google Group. File issues on the LiquidFun Issues Tracker or post your questions to with a mention of liquidfun.

    Please see Box2D/Documentation/Building/ to learn how to build LiquidFun and run the testbed.

    LiquidFun has a logo that you can use, in your splash screens or documentation, for example. Please see the Programmer's Guide for the graphics and further details.

    For applications on Google Play that integrate this tool, usage is tracked. This tracking is done automatically using the embedded version string (b2_liquidFunVersionString), and helps us continue to optimize it. Aside from consuming a few extra bytes in your application binary, it shouldn't affect your application at all. We use this information to let us know if LiquidFun is useful and if we should continue to invest in it. Since this is open source, you are free to remove the version string but we would appreciate if you would leave it in.
