動畫與cocos2d的安卓

Question

我做與框架動畫的cocos2d android.I有一系列的圖像相同的打擊的形象，我想裁剪圖像使用tivi在android系統到cocos2d中。 Plz幫助我？ link image

Animation animation = new Animation("abc", 0.2f); 
    for (int i = 1; i < 40; i++) { 
     try { 
      is = assetManager.open(new CCFormatter().format(
        "TV00%02d.png", i)); 
      bf = BitmapFactory.decodeStream(is); 
      bitmap = Bitmap.createBitmap(bf, 0, 0, bf.getWidth(), 
        bf.getHeight()); 
      bitmap2 = Bitmap 
        .createBitmap(bitmap, (int) (153 * (s.width/bg2 
          .getTexture().getWidth())), 
          (int) (261.5 * (s.height/bg2.getTexture() 
            .getHeight())), 
          (int) (87 * (s.width/bg2.getTexture() 
            .getWidth())), 
          (int) (97 * (s.height/bg2.getTexture() 
            .getHeight()))); 
      animation.addFrame(bitmap2); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
    return animation; 
} 

嘗試進行簡單的驗證碼的....使用最新的例子系列從cocs2d，機器人1 ..它有交給動畫基本概念.....你會從一系列示例得到的答案

海我希望這會幫助你很多。我用過CCSprite。它通過動畫支持所有屏幕。在480×800

public class MainMenuScreen extends CCColorLayer { 

private CCSprite newGame1; 
private CGSize size; // this is where we hold the size of current display 
private float scaleX, scaleY;// these are the ratios that we need to compute 

public static CCScene sence() { 
    CCScene ccScene = CCScene.node(); 
    CCLayer layer = new MainMenuScreen(ccColor4B.ccc4(69, 3, 3, 255)); 
    ccScene.addChild(layer); 
    return ccScene; 
} 

protected MainMenuScreen(ccColor4B color) { 
    super(color); 

    size = CCDirector.sharedDirector().winSize(); 

    CCSprite backGround = CCSprite 
      .sprite(CandygrabberImage.MENU_BACKGROUND); 
    this.setIsTouchEnabled(true); 
    // backGround.setContentSize(winSize); 
    backGround.setTag(1); 
    backGround.setScale(.5f); 
    backGround.setPosition(CGPoint.ccp(size.width/2.0f, 
      size.height/2.0f)); 
    backGround 
      .setScaleX(size.width/backGround.getTexture().getWidth()); 
    backGround.setScaleY(size.height 
      /backGround.getTexture().getHeight()); 

    addChild(backGround); 

    scaleX = size.width/480f;// assuming that all my assets are available 
           // for a 320X480(landscape) resolution; 
    scaleY = size.height/800f; 

    newGame1 = CCSprite.sprite("newgame1.png"); 
    CCAnimation buttonAnimation = CCAnimation.animation("", 1f); 
    buttonAnimation.addFrame("newgame1.png"); 
    buttonAnimation.addFrame("newgame2.png"); 
    buttonAnimation.addFrame("newgame3.png"); 
    buttonAnimation.addFrame("newgame4.png"); 
    buttonAnimation.addFrame("newgame5.png"); 
    buttonAnimation.addFrame("newgame6.png"); 
    buttonAnimation.addFrame("newgame7.png"); 
    buttonAnimation.addFrame("newgame8.png"); 

    CCIntervalAction buttonAction = CCAnimate.action(5, buttonAnimation, 
      false); 
    newGame1.runAction(CCRepeatForever.action(buttonAction)); 

    newGame1.setScaleX(scaleX); 
    newGame1.setScaleY(scaleY); 
    newGame1.setScale(aspect_Scale(newGame1, scaleX, scaleY)); 

    this.addChild(newGame1); 

    this.setIsTouchEnabled(true); 
} 

public float aspect_Scale(CCSprite sprite, float scaleX, float scaleY) { 
    float sourcewidth = sprite.getContentSize().width; 
    float sourceheight = sprite.getContentSize().height; 

    float targetwidth = sourcewidth * scaleX; 
    float targetheight = sourceheight * scaleY; 
    float scalex = (float) targetwidth/sourcewidth; 
    float scaley = (float) targetheight/sourceheight; 

    return Math.min(scalex, scaley); 
} 

}縮放CCSprite

要裁剪圖像或灰度圖像在動畫
