Hello.

I'm a complete noob in GS, so forgive me if my question might sound too simple.

I've followed the tutorial on how to store a ghost race replay and it works fine. This is exactly what I need. Unfortunately, the tutorial stops right before the last step: save the data (and load it) from inside a C# script.

Browsing the web I found something and I could make this, that works neatly:

		LogEventRequest request = new LogEventRequest();
		request.SetEventKey ("STORE_RACE_DATA");
		request.SetEventAttribute ("GHOST_DATA", jsonString);
		request.SetEventAttribute ("TRACK_NUMBER", DataController.dataController.currentRaceData.GetLevelNumber());
		request.SetEventAttribute ("RACE_TIME", Round1000 (DataController.dataController.currentRaceData.GetFinalTime()));
		request.SetEventAttribute ("STARSHIP_NUMBER", DataController.dataController.data.GetActiveStarhip());

		request.Send ((response) => {
			if (!response.HasErrors)
				Debug.Log ("added");
			else
				Debug.Log ("error " + response.Errors.JSON);
		});

The data structure I have is very similar to the one of the tutorial:

TRACK_NUMBER, RACE_TIME, STARSHIP_NUMBER are Numbers, while GHOST_DATA is of type JSON.

Here is where I have the trouble: GHOST_DATA is an array and if I create the Json string it is interpreted as a simple string. How could I save the array in GHOST_DATA?

I hope I was clear, thanks for any possible future help.

It's three days now that I'm trying to do the simplest thing:

I have my data stored, I have created the "get" event, i receive an empty request response, and...? now? should I use ScriptData? Should I use "ToString()" to get the strings? Should I get it as JSON and interpret it on the client? how and where do I use the setScriptData parameter that I wrote in the CloudCode, I don't understand why I should use script Data as soon as I'm retrieving normal data and not "extra data".

All documentation seems well done, then as soon as you try to dig into it you are left with dozens of questions, and tutorials magically end one step before answering those questions.

Can some one help me, or should I move to Parse?

I cannot contact you by Skype.

The races are asynchronous, the player actually races against a replay. Every user saves his replay and the replay is retrieved by other users. This guarantees that there are always opponents. If the critical user base will increase enough after the first app launch, I will create a real time challenge system.

What I would like to retrieve is the picture of the opponent that recorded the replay, for which I know the playerId.

I see two ways: I can create a local binary file and let the user upload the binary image himself to a public document accessible by future opponents, or store the fbid of the player so that it can retrieved by any user and the facebook picture taken by internet. What's the best solution in your opinion?

In the first case, I don't know how to upload a unique binary file for every user, going in update mode everytime it changes (without adding new files every time).

The second case it's not what I like. I don't like to duplicate information that is somewhere else, but if this is the solution, it's not hard to implement it. I would prefer a way to access directly to the opponent's user information and get his FBid without replicating it in a public document.

That's what I tried to do but loadPlayer seems to work only if the opponent player is a user's friend, and that's not the case when a challenge is organized. I need to access to Spark.loadPlayer for a playerId that is not known. For that reason I'm looking for a way to get the picture anyway going round this (wanted) limitation.

Also, supposing I have the fbId, how do I attach it to the ScriptData?

Anyway, I will go through my duplicate-fbId solution.

Thank you very much,

I finally succeeded in getting the data with this, is this the correct way?

	public void LoadReplayFromServer() {  // TODO
		Debug.Log("Load Replay From Server");

		string raceData, nickName;
		int? starshipNumber, timeTaken;

		LogEventRequest request = new LogEventRequest();
		request.SetEventKey ("GRD")
				.SetEventAttribute ("TN", DataController.dataController.currentRaceData.GetLevelNumber())
				.SetEventAttribute ("ST", Constants.constants.starshipCharacteristics[DataController.dataController.currentRaceData.starshipType].GetTier());

		request.Send ((response) => {
			if (response.HasErrors) {
				Debug.Log("FAIL with error " + response.Errors.JSON);
			} else {
				string json = response.ScriptData.JSON;
				Debug.Log (json);
				var N = SimpleJSON.JSON.Parse(json);

				raceData = N["selectedData"][0]["ghostData"].Value;
				nickName = N["selectedData"][0]["nickName"].Value;
				starshipNumber = N["selectedData"][0]["starshipNumber"].AsInt;
				timeTaken = N["selectedData"][0]["timeTaken"].AsInt;
			}
		});
	}

 Using this utility:

http://wiki.unity3d.com/index.php/SimpleJSON

I got no success in any way using GetString() and other methods that wouldn't force me to pass through a JSON.

How is the data transmission performed? does it transfer a JSON or does it transfer binary compressed data and then transformed in JSON on client-side?

Thanks.

Dear Jamie,

apologies are mine for having been maybe too urgent in my requests, no problem.

Sean has been very clear and kind, making all his efforts to help me. Thank him from me. And you are too.

Anyway I think that the major problem is not in your assistance that obviously depends from office hours, but on documentation, that is always on no matter whata you do, due to the fact that the often people (like me) that come to this service are not experts of mongodb, javascript and all the technology that you created. But unfortunately documentation looks like it has written by people that already know so many things around that are not necessarily clear.

For example: I've been banging my head for hours now. I want to retrieve a single element by a single cursor derived from a single query on my mongodb, and use it in another query to return additional information. The idea is to send to the user that requested a race replay, also the fbId of his opponent and if the opponents wants his picture to be displayed.

Probably it's a trivial operation, but I've been here since hours. In sql I would have written it in 1 line of code. My fault, and I'm now studying mongodb, but Gamesparks unfortunately doesn't help in this process, the training curve is sloooow: people could abandon before the fight, not me.

These are the questions that arose:

- how do I get a single value by a cursor. I want to get just the "playerId" value from the raceData I received. I did it but I keep on receiving "null" errors from javascript. The execution of 

var oppId = selectedData.curr().get("playerId");

 fails saying selectedData.curr() is null.

- I don't understand, once I will have the oppId that I'm desperately trying to get, if I am allowed to do something like this: 

Spark.setScriptData("selectedData", selectedData);
Spark.setScriptData("oppId", oppId);

 and receive both the information on the client side.

- I didn't undersand how to have the Cloud Code write on a console, so that I can fastly test locally.

I'm sure that all this information is available, or just obvious, unfortunately I'm still banging my head... :((

Thank you

I just wanted to say that I don't feel like opening a ticket just because your service works wonderfully, it's just me, not you :D :D

Here I am Sean.

I think I understood one thing, tell me if it's correct. I cannot access opponents Data because I access as user that is not a opponent's friend. Is it correct?

Anyway basically what I want is to be able to retrieve the playerId from the replay (that is opponent's id) and send to the client these information:

- boolean if the user wants to display the picture

- facebook picture or facebook id

Please tell me if you prefer to use a different media to talk as soon as the forum might be too slow. Thank you.
