lets to the point, so i want to make some configuration with my game to show Ads but I avoid to update game version too much, because of that I choose firebase remote config with this I can update setting/configuration without update the game version.
there is document for this but not very clear for newbie like me, you can check it here https://firebase.google.com/docs/remote-config/use-config-unity
I already make the script like on doc, but I don't understand how its work on show data because error string format, which is what I know on this firebase console is int format
the script like this :
public static _FirebaseRemoteConfig instance;
private void Awake()
{
instance = this;
}
Firebase.DependencyStatus dependencyStatus = Firebase.DependencyStatus.UnavailableOther;
// Use this for initialization
void Start()
{
Firebase.FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
{
dependencyStatus = task.Result;
if (dependencyStatus == Firebase.DependencyStatus.Available)
{
InitializeFirebase();
}
else
{
Debug.LogError(
"Could not resolve all Firebase dependencies: " + dependencyStatus);
}
});
}
public void InitializeFirebase()
{
System.Collections.Generic.Dictionary<string, object> defaults =
new System.Collections.Generic.Dictionary<string, object>();
defaults.Add("config_test_string", "default local string");
defaults.Add("config_test_int", 1);
defaults.Add("config_test_float", 1.0);
defaults.Add("config_test_bool", false);
Firebase.RemoteConfig.FirebaseRemoteConfig.SetDefaults(defaults);
Debug.Log("Remote config ready!");
}
public void FetchFireBase()
{
FetchDataAsync();
}
public void ShowData()
{
Debug.Log("maxCountToShowAdmob: " +
Firebase.RemoteConfig.FirebaseRemoteConfig.GetValue("MaxCountShowIntersitialAds").LongValue);
}
// Start a fetch request.
public Task FetchDataAsync()
{
Debug.Log("Fetching data...");
System.Threading.Tasks.Task fetchTask = Firebase.RemoteConfig.FirebaseRemoteConfig.FetchAsync(
TimeSpan.Zero);
return fetchTask.ContinueWith(FetchComplete);
}
void FetchComplete(Task fetchTask)
{
if (fetchTask.IsCanceled)
{
Debug.Log("Fetch canceled.");
}
else if (fetchTask.IsFaulted)
{
Debug.Log("Fetch encountered an error.");
}
else if (fetchTask.IsCompleted)
{
Debug.Log("Fetch completed successfully!");
}
var info = Firebase.RemoteConfig.FirebaseRemoteConfig.Info;
switch (info.LastFetchStatus)
{
case Firebase.RemoteConfig.LastFetchStatus.Success:
Firebase.RemoteConfig.FirebaseRemoteConfig.ActivateFetched();
Debug.Log(String.Format("Remote data loaded and ready (last fetch time {0}).",

I'm pretty new to writing asynchronous stuff in Unity. It is pretty easy to create a progress bar for asynchronous operation, but when it comes to doing it for the asynchronous task I'm not even sure when to start :(
public async void GetPhotoFromAndroidAndAddTexture(RawImage mainImage, string path)
{
await AddTextureToImage(mainImage, path);
}
public async Task<Texture2D> GetTextureFromAndroid(string path)
{
if(path != "" && path != " ")
{
#if UNITY_ANDROID
path = "file://" + path;
#endif
UnityWebRequest www = UnityWebRequestTexture.GetTexture(path);
var asyncOperation = www.SendWebRequest();
while(!asyncOperation.isDone)
{
await Task.Delay( 1000/30 );
}
return DownloadHandlerTexture.GetContent(www);
}
else
{
Debug.Log("The path is not correct!");
return null;
}
}
public async Task AddTextureToImage(RawImage mainImage, string path)
{
IProgress<int> progress;
Texture2D photoFromDevice = await GetTextureFromAndroid(path);
float textureH = photoFromDevice.height;
float textureW = photoFromDevice.width;
float aspectRat = textureH > textureW ? textureH/textureW : textureW/textureH;
mainImage.GetComponent<AspectRatioFitter>().aspectRatio = aspectRat;
mainImage.texture = photoFromDevice;
}
While the photo from android is being add as a texture I want to create a progress bar.
Thank you in advance for any suggestions
I can see no reason in your code why you should be using async at all. The only thing you actually are waiting for is the UnityWebRequest. async hasn't really any advantage over a simple Coroutine(IEnumerator) here.
In addition async stuff always also brings the problem of multi-threading ... Unity isn't thread safe so most of the API can only be used in the Unity mainthread.
You should rather stick to a Coroutine like e.g.
// wherever you want to show/use the progress
public float progress;
public void GetPhotoFromAndroidAndAddTexture(RawImage mainImage, string path)
{
StartCoroutine(AddTextureToImage(mainImage, path));
}
public IEnumerator AddTextureToImage(RawImage mainImage, string path)
{
Texture2D photoFromDevice;
if (path != "" && path != " ")
{
#if UNITY_ANDROID
path = "file://" + path;
#endif
UnityWebRequest www = UnityWebRequestTexture.GetTexture(path);
var asyncOperation = www.SendWebRequest();
while (!asyncOperation.isDone)
{
// wherever you want to show the progress:
progress = www.downloadProgress;
yield return null;
// or if you want to stick doing it in certain intervals
//yield return new WaitForSeconds(0.5f);
}
// you should also check for errors
if(www.error != null)
{
Debug.LogError("Something went wrong loading!", this);
yield break;
}
photoFromDevice = DownloadHandlerTexture.GetContent(www);
}
else
{
Debug.LogError("The path is not correct!", this);
yield break;
}
float textureH = photoFromDevice.height;
float textureW = photoFromDevice.width;
float aspectRat = textureH > textureW ? textureH / textureW : textureW / textureH;
mainImage.GetComponent<AspectRatioFitter>().aspectRatio = aspectRat;
mainImage.texture = photoFromDevice;
}
Alternatively often recommended is a kind of "dispatcher" or I prefer to call it a main thread worker where you can pass actions from other threads back to the main thread like e.g.
private ConcurrentQueue<Action> callbacks = new ConcurrentQueue<Action>();
private void Update()
{
while(callbacks.TryDequeue(var out a))
{
// Invokes the action in the main thread
a?.Invoke();
}
}
// example method to call
private void UpdateProgressBar(float progress)
{
// use progress
}
public async Task<Texture2D> GetTextureFromAndroid(string path)
{
if(path != "" && path != " ")
{
#if UNITY_ANDROID
path = "file://" + path;
#endif
UnityWebRequest www = UnityWebRequestTexture.GetTexture(path);
var asyncOperation = www.SendWebRequest();
while(!asyncOperation.isDone)
{
// add a callback for the main thread using a lambda expression
callbacks.Add(()=> { UpdateProgressBar(www.downloadProgress); });
await Task.Delay( 1000/30 );
}
return DownloadHandlerTexture.GetContent(www);
}
else
{
Debug.Log("The path is not correct!");
return null;
}
}
A cool way to have a simple progress bar for example can be achieved by using an UI.Image with
Image Type = Filled
Fill Method = Horizontal
Fill Origin = Left
now all you have to do is update the image.fillAmount
I get the following log during on-device debugging
Error:
*** [Play Games Plugin DLL] ERROR: Cloud load failed with status code 7
Basically the OnStateLoaded() callback function always returns the boolean success = false and I can't figure out the reason why.
All that the plugin debugging logs mention is "Cloud load failed with status code 7".
According to the android doc, 7 is a generic "developer error", see https://developer.android.com/reference/com/google/android/gms/appstate/AppStateStatusCodes.html#STATUS_DEVELOPER_ERROR
I tried a quick sample and everything worked ok. Here are my steps:
Created a new game in the play console
(https://play.google.com/apps/publish)
Made sure Saved Games is set
to ON
Linked an Android Application Remembering the application ID
(the number after the title) and the package ID
Created a new project in Unity
Added the play games plugin (Assets/Import Package.../Custom
Package)
Set the application ID (Google Play Games/Android Setup...)
Switched the platform to Android (File/Build Settings...)
Set the player settings (bundle identifier and the keystore info)
Added a new script component to the camera
Saved everything and hit build and run.

Currently my location not updating when I change it to different location via emulator. But it will change after I restart my application. This is what I write when the app launch
private void Application_Launching(object sender, LaunchingEventArgs e)
{
IsolatedStorageSettings Settings = IsolatedStorageSettings.ApplicationSettings;
GeoCoordinate DefaultLocation = new GeoCoordinate(-6.595139, 106.793801);
Library.GPSServices MyGPS;
if (!Settings.Contains("FirstLaunch") || (bool)Settings["FirstLaunch"] == true)
{
Settings["FirstLaunch"] = false;
Settings["LastLocation"] = DefaultLocation;
Settings["SearchRadius"] = 1;
}
//If key not exist OR key value was set to false, ask for permission to use location
if (!Settings.Contains("LocationService") || (bool)Settings["LocationService"] == false)
{
var result = MessageBox.Show(
"Jendela Bogor need to know your location to work correctly, do you want to allow it?",
"Allow access to your location?",
MessageBoxButton.OKCancel);
if (result == MessageBoxResult.OK)
{
Settings["LocationService"] = true;
MyGPS = new Library.GPSServices();
}
else
{
Settings["LocationService"] = false;
}
Settings.Save();
}
else if ((bool)Settings["LocationService"] == true)
{
MyGPS = new Library.GPSServices();
}
}
I store my location in my application setting IsolatedStorage with name Settings["LastLocation"]
How should I do to constantly update my location in the Background using MVVM Pattern (MVVM-Light) so my PushPin on map in the ThirdPageView always updated?
EDIT
public GPSServices()
{
if ((bool)Settings["LocationService"] == true)
{
if (_watcher == null)
{
_watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
_watcher.MovementThreshold = 20;
}
StartWatcher();
_watcher.PositionChanged += new EventHandler<GeoPositionChangedEventArgs<GeoCoordinate>>(watcher_PositionChanged);
_watcher.StatusChanged += new EventHandler<GeoPositionStatusChangedEventArgs>(watcher_StatusChanged);
}

}

{
if (e.Position.Location.IsUnknown)
{
MessageBox.Show("Please wait while your position is determined....");
return;
}
Settings["LastLocation"] = e.Position.Location;
Settings.Save();
}
System.Device.Location.GeoCoordinateWatcher provides what you need.
var geoWatcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
// This event fires every time the device location changes
geoWatcher.PositionChanged += (s, e) => {
//e.Position.Location will contain the current GeoCoordinate
};
geoWatcher.TryStart(false, TimeSpan.FromMilliseconds(2000));
is this helpful for you ? using GeocoordinateWatcher.PositionChanged event?
public Location()
{
GeoCoordinateWatcher location == new GeoCoordinateWatcher();
location.PositionChanged += new EventHandler<GeoPositionChangedEventArgs<GeoCoordinate>>(location_PositionChanged);
location.Start();
}
//event to track the location change
