Unity Android Services Google Play - Envoi d'un message de chaîne

Question

Je crée un jeu pour Android avec Unity Engine et j'utilise les services de jeu google play pour le multijoueur. J'ai un problème quand j'envoie un message de chaîne à un autre joueur. Je peux l'envoyer mais l'autre joueur ne peut pas le recived.

Envoyer le code:

public void SendMyUpdate(float posX, float posZ, Vector3 velocity, float rotY, float weapon, string opponentId) 
{ 
    DebugConsole.Log("OppenentSend " + opponentId); 
    bytesize = opponentId.Length * sizeof(byte); 
    _updateMessageLength = 26 + bytesize; 
    _updateMessage.Clear(); 
    _updateMessage.Add(_protocolVersion); 
    _updateMessage.Add((byte)'U'); 
    _updateMessage.AddRange(BitConverter.GetBytes(posX)); 
    _updateMessage.AddRange(BitConverter.GetBytes(posZ)); 
    _updateMessage.AddRange(BitConverter.GetBytes(velocity.x)); 
    _updateMessage.AddRange(BitConverter.GetBytes(velocity.z)); 
    _updateMessage.AddRange(BitConverter.GetBytes(rotY)); 
    _updateMessage.AddRange(BitConverter.GetBytes(weapon)); 
    //_updateMessage.AddRange(BitConverter.GetBytes(opponentHp)); 
    _updateMessage.AddRange(System.Text.Encoding.UTF8.GetBytes(opponentId));  
    byte[] messageToSend = _updateMessage.ToArray(); 
    PlayGamesPlatform.Instance.RealTime.SendMessageToAll(false, messageToSend); 
} 

Code de desiderata:

public void OnRealTimeMessageReceived(bool isReliable, string senderId, byte[] data) 
{ 
    // We'll be doing more with this later... 
    byte messageVersion = (byte)data[0]; 
    // Let's figure out what type of message this is. 
    char messageType = (char)data[1]; 
    if (messageType == 'U' && data.Length == _updateMessageLength) 
    { 
     float posX = BitConverter.ToSingle(data, 2); 
     float posZ = BitConverter.ToSingle(data, 6); 
     float velX = BitConverter.ToSingle(data, 10); 
     float velZ = BitConverter.ToSingle(data, 14); 
     float rotY = BitConverter.ToSingle(data, 18); 
     float weapon = BitConverter.ToSingle(data, 22); 
     //int opponentHp = BitConverter.ToInt16(data, 26); 
     string opponentId = System.Text.Encoding.UTF8.GetString(data); 

     // We'd better tell our GameController about this. 
     if (updateListener != null) 
     { 
      updateListener.UpdateReceived(senderId, posX, posZ, velX, velZ, rotY, weapon, opponentId); 
      DebugConsole.Log("OppenentRecived " + opponentId); 
     } 
    } 
    else if (messageType == 'F' && data.Length == _finishMessageLength) 
    { 
     // We received a final time! 
     float finalTime = System.BitConverter.ToSingle(data, 2); 
     //Debug.Log ("Player " + senderId + " has finished with a time of " + finalTime);  
    }

Vous devez vous rappeler d'ajouter un index où le convertisseur doit trouver l'octet gamme

ie: string opponentId = System.Text.Encoding.UTF8.GetString(data, int index);
