Could you please give an example of how to obtain information from the server

CombuManager.Start is already called automatically, you only need to wait in your script for the initialization to be finished (client and server exchange security keys to crypt the parameters of webservices):

public class Test : MonoBehaviour {
	IEnumerator Start () {

		while (!CombuManager.isInitialized)
			yield return null;

		// now Combu has been initialized and can be used to login etc
		CombuManager.platform.Authenticate (username, password, (bool success, string error) => {
			Debug.Log("Login: " + success + " -- " + error);
		});
	}
}

Hi. Thanks for your prompt response.

Sorry, I did not know how to ask my question. What I want is to use Combu to know the time of the server (server information), to validate restricted access per time (for a competition). I see that it is with GetServerInfo, but I can not understand how to call it from my own script. Could you please give an example?

Thank you in advance.

In the previous sample script after waiting for isInitialized you can access CombuManager.instance.serverInfo.time (it should be expressed in UTC), GetServerInfo is automatically called during initialization and the time is what it was during the initialization (in case you'd need to calculate some offset from date/time of clients).

Alternatively you can call GetServerInfo whenever you want (after CombuManager.isInitialized is true):

CombuManager.instance.GetServerInfo((bool success, CombuServerInfo info) =>
{
    if (success)
    {
        Debug.Log(info.time.ToString());
    }
});

It works perfectly, thank you very much!
