cocos2dx for lua 截屏功能

cocos2dx的utils类中包含截图功能,使用方法如下:

cc.utils:captureScreen(function(successed,outputFile)--第一个参数是截图成功或者失败的回调函数

if successed then--如果成功,返回true,否则返回nil

local sp = cc.Sprite:create(outputFile)

end

end,"captureTexture.png")第二个参数是保存文件名

看cocos源代码,截图文件会将保存在可写路径中或者绝对路径中,

std::shared_ptr<Image> image(new Image);

if (image)

{

image->initWithRawData(flippedBuffer.get(), width * height * 4, width, height, 8);

if (FileUtils::getInstance()->isAbsolutePath(filename))

{

outputFile = filename;

}

else

{

CCASSERT(filename.find("/") == std::string::npos, "The existence of a relative path is not guaranteed!");

outputFile = FileUtils::getInstance()->getWritablePath() + filename;

}

succeed = image->saveToFile
