AndEngine----PathModifierExample学习之模仿《w》行走

防着Example中的代码写的，没有什么好说的！直接贴代码：

public class PathModifierMy extends SimpleBaseGameActivity {private int mCameraWidth = 0;private int mCameraHeight = 0;private RepeatingSpriteBackground mRepeatingSpriteBackground;private BitmapTextureAtlas mPlayer;private TiledTextureRegion mPlayerRegion;Path mPlayerPath;AnimatedSprite mPlayerAnimatedSprite;PathModifier mPathModifier;LoopEntityModifier mLoopEntityModifier;private void initCameraSize() {mCameraWidth = getResources().getDisplayMetrics().widthPixels;mCameraHeight = getResources().getDisplayMetrics().heightPixels;}@Overridepublic EngineOptions onCreateEngineOptions() {initCameraSize();Camera camera = new Camera(0, 0, mCameraWidth, mCameraHeight);return new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED,new RatioResolutionPolicy(mCameraWidth, mCameraHeight), camera);}@Overrideprotected void onCreateResources() {BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");mRepeatingSpriteBackground = new RepeatingSpriteBackground(mCameraWidth, mCameraHeight, getTextureManager(),AssetBitmapTextureAtlasSource.create(getAssets(),"gfx/background_grass.png"),getVertexBufferObjectManager());mPlayer = new BitmapTextureAtlas(getTextureManager(), 128, 128);mPlayerRegion = BitmapTextureAtlasTextureRegionFactory.createTiledFromAsset(mPlayer, this, "player.png", 0, 0, 3, 4);mPlayer.load();}@Overrideprotected Scene onCreateScene() {mEngine.registerUpdateHandler(new FPSLogger());Scene scene = new Scene();scene.setBackground(mRepeatingSpriteBackground);/* Create the face and add it to the scene. */mPlayerAnimatedSprite = new AnimatedSprite(10, 10, 48, 64,this.mPlayerRegion, this.getVertexBufferObjectManager());// 构造path,6为Path链接的次数，即后面to的个数，可以大于，但是不能小于mPlayerPath = new Path(6)// 初始点.to(10, 10)// 到第一个拐点.to(mCameraWidth / 4.0f, mCameraHeight - 64)// 到第二个拐点.to(mCameraWidth / 2.0f, mCameraHeight / 2.0f)// 到第三个拐点.to(3 * mCameraWidth / 4.0f, mCameraHeight - 64)// 到第四个拐点.to(mCameraWidth - 64, 10);mPathModifier = new PathModifier(30, mPlayerPath, null,mPathModifierListener, EaseSineInOut.getInstance());mLoopEntityModifier = new LoopEntityModifier(mPathModifier);mPlayerAnimatedSprite.registerEntityModifier(mLoopEntityModifier);scene.attachChild(mPlayerAnimatedSprite);return scene;}IPathModifierListener mPathModifierListener = new IPathModifierListener() {@Overridepublic void onPathWaypointStarted(PathModifier pPathModifier,IEntity pEntity, int pWaypointIndex) {switch (pWaypointIndex) {case 0:mPlayerAnimatedSprite.animate(new long[] { 200, 200, 200 }, 6,8, true);break;case 1:mPlayerAnimatedSprite.animate(new long[] { 200, 200, 200 }, 0,2, true);break;case 2:mPlayerAnimatedSprite.animate(new long[] { 200, 200, 200 }, 6,8, true);break;case 3:mPlayerAnimatedSprite.animate(new long[] { 200, 200, 200 }, 0,2, true);break;case 4:mPlayerAnimatedSprite.animate(new long[] { 200, 200, 200 }, 9,11, true);break;default:break;}}@Overridepublic void onPathWaypointFinished(PathModifier pPathModifier,IEntity pEntity, int pWaypointIndex) {}@Overridepublic void onPathStarted(PathModifier pPathModifier, IEntity pEntity) {Debug.d(" [onPathStarted] ");}@Overridepublic void onPathFinished(PathModifier pPathModifier, IEntity pEntity) {Debug.d(" [onPathFinished] ");}};}

有点郁闷的是，AndEngine里面参数真是让人蛋疼菊紧呀！都是接口，方法实现后，代码又长又难看！不知道这样做是为什么呢？可能现在还没有得到其精髓吧！
