Overview of this book

AndEngine is a very popular open source OpenGL (open graphics library) Android game engine, used to create mobile games quickly while maintaining the ability to fully customize them. This book will guide you through the whole development process of creating a mobile game for the Android platform using one of the most popular and easy-to-use game engines available today. Beginning with the very basics, you will learn how to install AndEngine, gather graphics, add sound and music assets, and design game rules. You will first design an example game and enhance it by adding various features over the course of the book. Each chapter adds more colors, enhances the game, and takes it to the next level. You will also learn how to work with Box2D, a popular 2D physics engine that forms an integral part of some of the most successful mobile games. By the end of the book, you will be able to create a complete, interactive, and fully featured mobile game for Android and publish it to Google Play.

When we need to connect two bodies together in Box2D, we use joints. Joints always connect two bodies and never more. Multiple joints are then required to link more bodies together. A joint always connects a dynamic body with another body that can be either static, kinematic, or dynamic. Joints between kinematic and static bodies are allowed but have no effect.

Note

Joints update the body positions and rotations based on the type of joint. You can define two bodies in an arbitrary location and rotation, but if the joint restricts the position, for example, the bodies will immediately transform to the proper position after the simulation starts.

A joint can also specify whether the connected bodies should collide or not. We are going to see the basic joints available in Box2D, and we are going to implement one of them.

The revolute joint

The revolute joint is like a pin or hinge. Imagine that you cut two bodies from some paper and pin them together. The pin hole in the first body is the...
