Coco2dx制作一个3D旋转的效果

建了工程之后修改HelloWorldScene.cpp文件，修改部分为

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
    //////////////////////////////
    // 1. super init first
    if ( !Layer::init() )
    {
        return false;
    }

    ry = 0;

    auto rootNode = CSLoader::createNode("MainScene.csb");

    addChild(rootNode);

    Size visibleSize = Director::getInstance()->getVisibleSize();

    s = Sprite::create("HelloWorld.png");
    s->setAnchorPoint(Vec2(0, 0.5f));

    s->setPosition(visibleSize.width / 2, visibleSize.height / 2);

    addChild(s);

    scheduleUpdate();

    return true;
}

void HelloWorld::update(float dt) {
    ry++;
    s->setRotation3D(Vec3(0, ry, 0));
}

HelloWorldScene.h也要修改

class HelloWorld : public cocos2d::Layer
{
private:
    cocos2d::Sprite *s;
    float ry;

public:
    // there's no 'id' in cpp, so we recommend returning the class instance pointer
    static cocos2d::Scene* createScene();

    // Here's a difference. Method 'init' in cocos2d-x returns bool, instead of returning 'id' in cocos2d-iphone
    virtual bool init();

    // implement the "static create()" method manually
    CREATE_FUNC(HelloWorld);

    void update(float dt);
};

然后就可以看到旋转效果：
