What PlayN is
PlayN is a free, open-source Java library for developers building 2D games for desktop, browser, and mobile platforms. It lets developers program against one API and deploy to Android, iOS, Linux, macOS, the web, and Windows. Graphics options include OpenGL, QuadBatch with built-in shaders, Surface, a 2D scene graph, and a CPU-based Canvas drawing API with text rendering. The library supports music and sound effects, along with mouse, touch, and keyboard input. TriplePlay adds a UI toolkit, tweened and keyframe animation, and particle systems. Development resources include tutorials, demos, Javadocs, release notes, setup instructions, and an overview. Its cookbook offers guidance on graphics, scene graphs, sound, input, networking, assets, and builds with Maven and IDEs. A physics demo shows JBox2D integration. Community help is available through a mailing list and Stack Overflow. PlayN is licensed under Apache 2.0 and costs nothing.
