Built on Android Game Application Use AndEngine

Step 1: extends BaseGameActivity on AndEngine

PHP:

onLoadEngine
onLoadResources
onLoadScene
onLoadComplete

Step 2: Declaration variable

PHP:

    private static final int CAMERA_WIDTH = 720;
    private static final int CAMERA_HEIGHT = 480;

    private Camera mCamera;
    private BitmapTextureAtlas mBitmapTextureAtlas;
    private TiledTextureRegion mFaceTextureRegion;

Step 3: new variable on method

PHP:

public Engine onLoadEngine() {
        // TODO Auto-generated method stub
        this.mCamera = new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);
        return new Engine(new EngineOptions(true, ScreenOrientation.LANDSCAPE,
                new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT),
                this.mCamera));
    }

Step 4: Load Resources on Method onLoadResources

PHP:

@Override
    public void onLoadResources() {
        this.mBitmapTextureAtlas = new BitmapTextureAtlas(64, 32,
                TextureOptions.BILINEAR_PREMULTIPLYALPHA);
        BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
        this.mFaceTextureRegion = BitmapTextureAtlasTextureRegionFactory
                .createTiledFromAsset(this.mBitmapTextureAtlas, this,
                        "face_circle_tiled.png", 0, 0, 2, 1);

        this.mEngine.getTextureManager().loadTexture(this.mBitmapTextureAtlas);
    }

Step 5: Load game on onLoadScene

PHP:

@Override
    public Scene onLoadScene() {
        // TODO Auto-generated method stub
        this.mEngine.registerUpdateHandler(new FPSLogger());

        final Scene scene = new Scene();
        scene.setBackground(new ColorBackground(0.09804f, 0.6274f, 0.8784f));

        final int centerX = (CAMERA_WIDTH - this.mFaceTextureRegion.getWidth()) / 2;
        final int centerY = (CAMERA_HEIGHT - this.mFaceTextureRegion
                .getHeight()) / 2;
        final Ball ball = new Ball(centerX, centerY, this.mFaceTextureRegion);

        Log.d("FishingonLoadScene",  "onLoadScene dx = " + ball.getX()
                + "dy = " + ball.getY());

        scene.attachChild(ball);

        return scene;
    }

Insert class Ball:

PHP:

private static class Ball extends AnimatedSprite {
        private final PhysicsHandler mPhysicsHandler;

        public Ball(final float pX, final float pY,
                final TiledTextureRegion pTextureRegion) {
            super(pX, pY, pTextureRegion);
            this.mPhysicsHandler = new PhysicsHandler(this);
            this.registerUpdateHandler(this.mPhysicsHandler);
            mPhysicsHandler.setVelocity(DEMO_VELOCITY, DEMO_VELOCITY);
        }

        @Override
        protected void onManagedUpdate(final float pSecondsElapsed) {
            if (this.mX < 0) {
                this.mPhysicsHandler.setVelocityX(DEMO_VELOCITY);
            } else if (this.mX + this.getWidth() > CAMERA_WIDTH) {
                this.mPhysicsHandler.setVelocityX(-DEMO_VELOCITY);
            }

            if (this.mY < 0) {
                this.mPhysicsHandler.setVelocityY(DEMO_VELOCITY);
            } else if (this.mY + this.getHeight() > CAMERA_HEIGHT) {
                this.mPhysicsHandler.setVelocityY(-DEMO_VELOCITY);
            }
            Log.d("FishingonManagedUpdate", "onManagedUpdate dx = " + this.getX() + "dy = "
                    + this.getY());
            super.onManagedUpdate(pSecondsElapsed);
        }
    }
