PlayN Hello World
This sample program just displays a background image and listens for clicks/touches and sticks a rotating image at the place where the click/touch happened. It mainly serves as a minmal example of all the scaffolding needed to make a game run on all the different platforms, and it can be a good project to hack on when you want to try some simple code snippet.
Building and running
Using Maven, do:
cd playn-samples/hello mvn test -Pjava
For setting up in an IDE or building for Android, iOS and HTML, see the development environment documentation on the PlayN website.
