I used the following code to write the achivments from Game Cente.
Social.ReportProgress("myAchivementID", 2.5f, (bool success) => {
// handle success or failure
Debug.Log("ReportProgress: " + success);
});
The first try, I saw it successed by the callback, and I actually saw it show 2 percent degree on the Game Center Achiviment UI.
But after any try, it always failed, and I saw the callback show “Already reported myAchivementID”.
How could it be? If it’s once-for-used per achivment?
I need your help, thanks !!
