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(0, 0, 300, 300));
  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);
