How to save file permanently to user device

cocos2d-x C++
1

Hi everyone,

I just noticed that whenever i compiled and re-deploy my game on test device, my saved file has been replaced with newly created file, that’s mean if i update my game to newer version, all users record will be lost. Right now, my method look like this:

std::string path = FileUtils::getInstance()->getWritablePath() + “\Player_Data.dat”;
std::ifstream readData(path, std::ios::binary);

if (readData.is_open())
{

       //if file existed, read data from file

    readData.read((char*)&_playerData, sizeof(PlayerData));
}
else
{

       //if not, create new file with default value

    _playerData.bestScore = 0;
    saveToFile();
}
readData.close();

Do anybody have a suggestion?

Hi,

Is it for Android version of the app?

There was topic , with suggestion to change adb deploy script to not uninstall app, but reinstalling app. Or your issue is with your code logic, that you overwriting save file in any case?
