【已解决】RenderTexture问题，无法获取getData()

Cocos2d-x
#1

RenderTexture *render = RenderTexture::create(Director::getInstance()->getWinSize().width, Director::getInstance()->getWinSize().height,Texture2D::PixelFormat::RGBA8888);
render->beginWithClear(0.0f, 0.0f, 0.0f, 0.0f);
sprite_chess->visit();
render->end();
render->retain();

Image *finalImage = render->newImage();

unsigned char *pData = finalImage->getData();

版本cocos2dx 3.2

finalImage得到的是正常的地址
pData得到的是null，问题就是这里，2.x版本是可以获取到数据的

render->getSprite()得到的精灵是正常的，因为我addchild显示出来了，所以render这点是正常的

密切关注这个！！！:6::6::6:

已经解决了，加了一句代码
RenderTexture *render = RenderTexture::create(Director::getInstance()->getWinSize().width, Director::getInstance()->getWinSize().height,Texture2D::PixelFormat::RGBA8888);
render->beginWithClear(0.0f, 0.0f, 0.0f, 0.0f);
sprite_chess->visit();
render->end();
Director::getInstance()->getRenderer()->render(); 就是这句
render->retain();

#4

或者在下一帧处理。

#5

真是醉了，就差这一句：Director::getInstance()->getRenderer()->render();

#6

呵呵

cc.Director:getInstance():getRenderer():render() 这一句在lua里面怎么实现？
