lua 如何让物体移动？

这个，lua只是脚本语言，想让图片运动的话用引擎吧。

例：local a = CCSprite:create("XXX.png")

local moveto = CCMoveTo:create(ccp(30, 20), 2)

a:runAction(moveto)

在 cocos2d-x 2.x 的 AssetsManager sample 范例中提供了一个 reset 方法，这个方法使用系统命令递归删除文件夹。

void UpdateLayer::reset(cocos2d::CCObject *pSender)

{

pProgressLabel->setString(" ")

// Remove downloaded files

#if (CC_TARGET_PLATFORM != CC_PLATFORM_WIN32)

string command = "rm -r "

// Path may include space.

command += "\"" + pathToSave + "\""

system(command.c_str())

#else

string command = "rd /s /q "

// Path may include space.

command += "\"" + pathToSave + "\""

system(command.c_str())

#endif

// Delete recorded version codes.

getAssetsManager()->deleteVersion()

createDownloadedDir()

}
