Creating a physics-based moving platform

Most platform-style games have some sort of moving platform, which challenges the player to land with accurate timing. From a developer's standpoint, the platform is simply a physics-enabled body that moves from one location to another. In this recipe, we will see how to create a horizontally-moving platform.

Getting ready...

Create a new activity class named MovingPhysicsPlatformActivity that extends BaseGameActivity.

How to do it...

Follow these steps to build our MovingPhysicsPlatformActivity activity class:

1. Insert the following code snippet into our activity to make it functional:

   @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.SCREEN_ON...
