Box2D for Flash Games will guide you through the process of making a Flash physics game starting from the bare bones and taking you by hand through complex features such as forces, joints and motors. As you are learning, your game will have more and more features, like the physics games you are used to playing.
The book analyzes two of the most played physics games, and breaks them down to allow readers to build them from scratch in a step-by-step approach.

After many months of hard work, I am proud to present Feathers 2.0 BETA. This is the first major update to Feathers since 1.0. I’ve been listening carefully to community feedback, and I’ve tried to focus on improving the most common pain points. If all went well, you’ll need to write less boilerplate code and you can get started easier with better defaults.
