cocos2d截屏

//cocos2d-x 3.x 版本的新方法

utils::captureScreen(CC_CALLBACK_2(GameResultLayer::afterCaptured,this),"screenshoot.png");

//回调

void GameResultLayer::afterCaptured(bool succeed,conststd::string& outputFile)

{

    if (succeed)

    {

        CCLOG("outputFile = %s", outputFile.c_str());

    }

    else

    {

        log("Capture screen failed.");

    }

}

//cocos2d-x 2.x 版本的老方法

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

    

    Scene * curScene = Director::getInstance()->getRunningScene();

    Point ancPos = curScene->getAnchorPoint();

    

    //定义一个屏幕大小的渲染纹理

    RenderTexture* renderTexture = RenderTexture::create(visibleSize.width, visibleSize.height, Texture2D::PixelFormat::RGBA8888);

    

    //渲染纹理开始捕捉

    renderTexture->begin();

    

    // 缩小屏幕截屏区域

//    curScene->setScale(.5);

//    curScene->setAnchorPoint(cocos2d::Point(0, 0));

    

    //绘制当前场景

    curScene->visit();

    

    //结束

    renderTexture->end();

    

    //保存png

    renderTexture->saveToFile("screenshoot.png", Image::Format::PNG);

    

    // 恢复屏幕尺寸

//    curScene->setScale(1);

//    curScene->setAnchorPoint(ancPos);
