Good tutorial on using Tasks and Async

Unity Services

Hi,

So I’ve never used Tasks before and the unity documentation isn’t very helpful for someone new to tasks.

public async void LoadSomeData()
{
    Dictionary<string, string> savedData = await CloudSaveService.Instance.Data.LoadAsync(new HashSet<string>{"key"});

    Debug.Log("Done: " + savedData["key"]);
}

What is the best way to actually save that retrieved data? I can’t pass in a ref, in or out with async. So I am forced to pass in a reference to a class I’ve created. This doesn’t seem that elegant.

Thanks!

You can pass data in and out of an asynchronous method. To return data, use a Task.

e.g. When joining a multiplayer lobby. The QuickJoin method might look like

        public async Task<Lobby> QuickJoinLobby()
        {

            try
            {
                //return currentLobby;
                currentLobby = await Lobbies.Instance.QuickJoinLobbyAsync();
                .
                Debug.Log($"Quick Joining with code {currentLobby.Data["JoinCodeKey"].Value}"); 
                .
                .
                return currentLobby;                              
            }
            catch
            {
                Debug.Log("Quick Lobby Join Exceptions, I guess I'll create my own Lobby");
                return null;
            }
        }

And would be called with
var lobby = await networkLobby.CreateNewLobby();

Thank you, that C# tutorial is helpful but still a big verbose. Would love to see an example in the Unity Documentation :).
