本文主要是介绍quick cocos 截屏并保存，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

调用cc.RenderTexture 即可。

    --需要截的屏幕大小local render_texture = cc.RenderTexture:create(640, 1136)--开始截屏render_texture:begin()--截self.node_container包含的内容self.node_container:visit()--关闭render_texture:endToLua()--调用local photo_texture = render_texture:getSprite():getTexture()local sprite_photo = cc.Sprite:createWithTexture(photo_texture)--截屏后的sprite_photo为原始图片沿y轴翻转后的样子。若需要原图，调用如下函数.sprite_photo:flipY()local result = render_texture:saveToFile("share.png", cc.IMAGE_FORMAT_PNG)-- saveToFile函数会默认添加根路径。if not result thenprint("save file failed")end

注：若需要让某些图片强制渲染，调用sprite:visit()方法。

//C++对应的RenderTexture类的saveToFile方法。
bool RenderTexture::saveToFile(const std::string& fileName, Image::Format format, bool isRGBA)  
{  CCASSERT(format == Image::Format::JPG || format == Image::Format::PNG,  "the image can only be saved as JPG or PNG format");  if (isRGBA && format == Image::Format::JPG) CCLOG("RGBA is not supported for JPG format");  //保存图片文件的路径  std::string fullpath = FileUtils::getInstance()->getWritablePath() + fileName;  //初始化将纹理保存到文件的自定义渲染指令  _saveToFileCommand.init(_globalZOrder);  //设置自定义渲染指令的回调函数  _saveToFileCommand.func = CC_CALLBACK_0(RenderTexture::onSaveToFile, this, fullpath, isRGBA);  Director::getInstance()->getRenderer()->addCommand(&_saveToFileCommand);  return true;  
}
