Creating a physics-based rope bridge

With the Box2D physics extension, creating complex physics-enabled elements is simple. One example of such a complex element is a rope bridge that reacts to collisions. In this recipe, we will see how to implement a method that creates a rope bridge tailored to specific parameters that control the bridge's size and physical properties.

Getting ready...

Create a new activity class named PhysicsBridgeActivity that extends BaseGameActivity.

How to do it...

Follow these steps to build our PhysicsBridgeActivity activity class:

1. Place the following code in our activity to give us a standard AndEngine activity:

   @Override
   public Engine onCreateEngine(final EngineOptions pEngineOptions) {
     return new FixedStepEngine(pEngineOptions, 60);
   }
   @Override
   public EngineOptions onCreateEngineOptions() {
     return new EngineOptions(true, 
       ScreenOrientation.LANDSCAPE_SENSOR,
       new FillResolutionPolicy(), 
       new Camera(0, 0, 800, 480))
       .setWakeLockOptions(WakeLockOptions...
