Known issues & workarounds

Example from http://docs.unity3d.com/Manual/UNetInternetServicesOverview.html does not work:

http://forum.unity3d.com/threads/matchmaker-issue-working-from-the-same-pc-not-working-from-different-pc.336945/

// This seems to be occasionally required for online matchmaking
// This is your 5-digit project UNET ID at multiplayer.unity3d.com
// This is due to be fixed in an upcoming patch release (was not in 5.1.1p3)
void Awake() 
{
    PlayerPrefs.SetString( "CloudNetworkingId", "12345" );
}

Snippets

// ClientRpc is called on the server - invokes on clients [ClientRpc] public void RpcMyMethod( string msg ) { Debug.Log( "Got message from the server: " + msg ); }

// Commands are called on clients - invokes on the server // Note that you can only send commands if you own the object it calls from [Command] public void CmdMyMethod( string msg ) { Debug.Log( "Got message from a client: " + msg ); }

// SyncVars are automatically sent from the server to other clients. // Note that you still need a command to notify the server of the change // if it comes from a client. Hook is optional [SyncVar(hook="OnSomeoneChangedMyString")] public string myString;

public void OnSomeoneChangedMyString( string myString ) { this.myString = myString; Debug.Log( "Changed myString to " + myString ); }
