cocos2dx Sprite的多种创建方法

1.通过文件创建

Sprite *bg = Sprite::create("backGround.jpg");

2.通过图片的某个区域创建

   SpriteFrame *frame = SpriteFrame::create("pean.jpg", Rect(, , , ));
   Sprite *pean = Sprite::createWithSpriteFrame(frame);
   bg->addChild(pean);

3.通过texture2d纹理创建(用这种方法的少)

     Image *image = new Image();
     image->initWithImageFile("pean.jpg");

     Texture2D *texture = new Texture2D();
     texture->initWithImage(image);

     Sprite *pean = Sprite::createWithTexture(texture);
     bg->addChild(pean);

4.用SpriteFrameCache(plist文件通过zwoptex创建)

 SpriteFrameCache::getInstance()->addSpriteFramesWithFile("person.plist");

 SpriteFrame *frame = SpriteFrameCache::getInstance()->getSpriteFrameByName("navigationbar_back.png");

 Sprite *pean = Sprite::createWithSpriteFrame(frame);
 bg->addChild(pean);
