How to convert match data to byte?
Hi
Im a beginner trying to make a turn based game using the google game services unity plugin, https://github.com/playgameservices/play-games-plugin-for-unity/blob/master/TBMP.md. I have come over some sample codes and put them in my game and everything is actually working fine (to my surprice). However, ofcourse, the sample games doesnt convert the same kind of data as I want to do in my game. My specific game data consists of ints and bools and from what I can see my code only converts strings.. right? So my question is: How do I modify the code so it will work with my game data? I want to be able to convert and "deconvert". Im actually not sure about all thats going on in this script... but I think the convertion and deconvertion happens on lines 110-240.
public class SaveSample : MonoBehaviour {
System.Action<bool> mAuthCallback;
GameData slot0;
bool mSaving;
private Texture2D mScreenImage;
// Use this for initialization
void Start () {
slot0 = new GameData("New game");
mAuthCallback = (bool success) => {
if (success) {
Debug.Log("Authentication was successful!");
slot0.State = "Click load or save";
}
else {
Debug.LogWarning("Authentication failed!");
}
};
PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder()
.EnableSavedGames()
.Build();
PlayGamesPlatform.InitializeInstance(config);
// Activate the Play Games platform. This will make it the default
// implementation of Social.Active
PlayGamesPlatform.Activate();
// enable debug logs (note: we do this because this is a sample; on your production
// app, you probably don't want this turned on by default, as it will fill the user's
// logs with debug info).
PlayGamesPlatform.DebugLogEnabled = true;
//Login explicitly for this sample, usually this would be silent
PlayGamesPlatform.Instance.Authenticate(mAuthCallback, false);
