bool HelloWorld::init(){    bool bRet = false;    do     {        CC_BREAK_IF(! CCLayer::init());CCSprite * sprite = CCSprite::create("image1.png");this->addChild(sprite);//获得CCSprite的默认坐标CCLog("CCSprite.x=%f,CCSprite.y=%f",sprite->getPosition().x,sprite->getPosition().y);//获得CCSprite的默认锚点CCLog("sprite1Anchor.x=%f,sprite1Anchor.y=%f",sprite->getAnchorPoint().x,sprite->getAnchorPoint().y);//获得CCLayer的默认坐标CCLog("CCLayer.x=%f,CCLayer.y=%f",this->getPosition().x,this->getPosition().y);//获得CCLayer的默认锚点CCPoint point = this->getAnchorPoint();CCLog("layerAnchor.x=%f,layerAnchor.y=%f",point.x,point.y);        bRet = true;    } while (0);    return bRet;}

CCScene* HelloWorld::scene(){    CCScene * scene = NULL;    do     {        // 'scene' is an autorelease object        scene = CCScene::create();        CC_BREAK_IF(! scene);        // 'layer' is an autorelease object        HelloWorld *layer = HelloWorld::create();        CC_BREAK_IF(! layer);        // add layer as a child to scene        scene->addChild(layer);layer->show();    } while (0);    // return the scene    return scene;}

void HelloWorld::show(){//获得CCScene的默认坐标CCScene * scene = (CCScene *)this->getParent();CCLog("CCScene.x=%f,CCScene.y=%f",scene->getPosition().x,scene->getPosition().y);//获得CCScene的默认锚点CCPoint point = scene->getAnchorPoint();CCLog("SceneAnchor.x=%f,SceneAnchor.y=%f",point.x,point.y);}

实践证明这三个东西的默认坐标都是0,0 默认锚点都是0.5,0.5
