Hi Shane, is there a way to force the challenge to an end? I am not using the challenge in your typical turns based way. Mine is both players playing game at the same time. My idea about ending is that when a player is done, he sends message that he is done, and when all players are done, I'd like to get a message about end of the challenge. Is there are a support in GameSparks for this kind of challenge?
Thanks,
Roman
Katie,
thanks for reply. I do use combination of GS challenge messages and custom messages. If challenge is non turn based, how do I make it to complete? Is there a way to force it to COMPLETE state? How does non turn based challenge normally complete? Is there a problem if I never make challenge into a COMPLETE state and leave it in working state in GameSparks?

@Roman Koval: you probably want to create some custom Cloud Code to handle your game logic, in which you explicitly determine the winner using
SparkChallenge.winChallenge()
somewhere.
@Esteban Traina: I think you can use the ListChallengeRequest and specify the state as "WAITING", so something like:
{
"@class" : ".ListChallengeRequest",
// ..
"state" : "WAITING",
}
@Rene van den Berg: Tried "state" : "WAITING" with no results, but I changed it to "RECEIVED" and there is. Thanks!
Oops, my bad! I meant to say RECEIVED, indeed - as the docs describe: "The challenge has been issued to the current player and is waiting to be accepted."
@Rene van den Berg.
Thanks for your reply. Is there a problem if I never make challenge into a COMPLETE state and leave it in working state in GameSparks?
@Roman: I'm not sure, I suppose it depends on the needs of your game. Someone at GameSparks may be able to answer this question a little better. I do seem to recall there's an "end date" requirement for Challenges, not quite sure if you can make this something like "1000 years from now" to keep them open indefinitely.
Another possibility, if you want to somehow mark the game as complete but not having a winner, is to use
challenge.drawChallenge()
which will do just what it says on the tin: declare the Challenge a draw.
Thanks Rene, I mistook you for the support guy :-).
Customer Support
Turn-based multiplayer gameplay between two or more players that can check in and play their turn when it's convenient. Similar to play-by-mail games and, more electronically, play-by-email.
Be default GameSparks Challenges require both players to accept the challenge before posting their scores, while this is ideal for some games, it's not the best for spontaneously challenging a friend to a game and saying "Hey! Bet you can't beat this!"
The flow of an Asynchronous Challenge looks like:
1. Player 1 gets an awesome score, decides to challenge another user to beat it
2. Player 1 picks who to challenge and sends a CreateChallengeRequest to the user of their choice (Player 2)
3. Player 1 receives a successful CreateChallengeResponse, takes the ChallengeInstanceId and sends a LogEventRequest to save their score in that Challenge Instances ScriptData.
In you code this should all happen very quickly.
4. Player 2 receives a message that Player 1 has challenged them to beat their score.
5. Player 2 sends a GetChallengeRequest to retrieve the latest details of the challenge (including Player 1's score in the Script Data).
6. Player 2 sends AcceptChallengeRequest and on a successful AcceptChallengeResponse the game loads the appropriate level.
7. Player 2 gets a score and sends a LogChallengeEventRequest with their score and the Cloud Code script will decide the winner.
8. Both Player 1 and Player 2 receive a message declaring who won and who lost.
First thing we are going to do is create our "SetScoreOnChallenge" event, it should look like:
We'll take the challengeInstanceId so we know which challengeInstance we want to save the score in. We'll also take the score we want to save.
Next up, create the event "SetScoreAndCalculateOutcome", which should look like:
This one doesn't take a challengeInstanceId attribute because this will only ever be called with a LogChallengeEvent, which already includes the challengeInstanceId. We don't use LogChallengeEvent for the previous event because it has logic associated with progressing the challenge.
Next up we'll create our Challenge:
The two very important thing to take note of here are "Turn / Attempt Consumers" which has been set to our "SetScoreAndCalculateOutcome" event. Next is "Leaderboard" which has been set to "Scripted Outcome", this is so we can run custom logic to determine the victor.
The next thing we need to do is add in our Cloud Code.
Navigate to Configurator -> Cloud Code -> Events -> SetScoreOnChallenge and add in the following:
//Load our challenge with the challengeId we passed var challenge = Spark.getChallenge(Spark.getData().challengeInstanceId); //We get the score attribute passed from our game var player1Score = Spark.getData().score; //Store the turns in our challenge's scriptData challenge.setScriptData("player1Score", player1Score);Now navigate to Configurator -> Cloud Code -> Challenge Events -> SetScoreAndCalculateOutcome and add in the the following:
//Load our challenge var challenge = Spark.getChallenge(Spark.getData().challengeInstanceId); //We get the score attribute and save it to the scriptData var player2Score = Spark.getData().score; challenge.setScriptData("player2Score", player2Score); //Player 1 will be our challenger var player1 = Spark.loadPlayer(challenge.getChallengerId()); var player1Score = challenge.getScriptData("player1Score") //Player 2 is the player who triggered this event var player2 = Spark.getPlayer(); //We could also load players from challenge.getChallengedPlayerIds()[] or challenge.getAcceptedPlayerIds()[] //Call our play function play(); function play() { if(player1Score > player2Score){ //challenge.setScriptData("winner", player1); challenge.winChallenge(player1); } if(player2Score > player1Score){ //challenge.setScriptData("winner", player2); challenge.winChallenge(player2); } }With that done we are ready to test! Head on over to the Test Harness and follow along:
Player 1 gets an awesome score and picks a friend to challenge:
{ "@class": ".CreateChallengeRequest", "accessType": "PRIVATE", "challengeShortCode": "asyncChallenge", "endTime": "2015-02-19T00:00Z", "usersToChallenge": "54d0b761e4b021c187558337" } { "@class": ".CreateChallengeResponse", "challengeInstanceId": "54d0d867e4b021c187559b13", "scriptData": null }In our game, on a successful CreateChallengeResponse we'll take the newly created challengeInstanceId and immediately send a LogEventRequest to post our score:
{ "@class": ".LogEventRequest", "eventKey": "SetScoreOnChallenge", "challengeInstanceId": "54d0d867e4b021c187559b13", "score": "356" } { "@class": ".LogEventResponse", "scriptData": null }Player 1 has now challenged their friend and set their score in the ScriptData of the challenge, they can go back to playing their game.
Player 2 will receive a message (or push notification!) alerting them that Player 1 has gotten a crazy high score on your game, it will look something like this:
{ "@class": ".ChallengeIssuedMessage", "messageId": "54d0d867e4b021c187559b14", "notification": true, "summary": ".ChallengeIssuedMessage", "who": "oisin", "challenge": { "challengeId": "54d0d867e4b021c187559b13", "state": "ISSUED", "scriptData": {}, "shortCode": "asyncChallenge", "startDate": null, "accepted": [ { "name": "oisin", "id": "54d0b768e4b021c187558356" } ], "challenged": [ { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenger": { "name": "oisin", "id": "54d0b768e4b021c187558356" }, "expiryDate": null, "endDate": "2015-02-19T00:00Z", "challengeName": "Asynchronous Challenge" }, "playerId": "54d0b761e4b021c187558337" }You'll notice the scriptData is empty, that's because the message was sent before we logged our score to the challenge, to overcome this we can use GetChallengeRequest which will reflect the updated challenge:
{ "@class": ".GetChallengeRequest", "challengeInstanceId": "54d0d867e4b021c187559b13" } { "@class": ".GetChallengeResponse", "challenge": { "challengeId": "54d0d867e4b021c187559b13", "state": "ISSUED", "scriptData": { "player1Score": "356" }, "shortCode": "asyncChallenge", "startDate": null, "accepted": [ { "name": "oisin", "id": "54d0b768e4b021c187558356" } ], "challenged": [ { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenger": { "name": "oisin", "id": "54d0b768e4b021c187558356" }, "expiryDate": null, "endDate": "2015-02-19T00:00Z", "challengeName": "Asynchronous Challenge" }, "scriptData": null }Now that we have the challenge details we can display the relevant details to Player 2, next we have Player 2 send an AcceptChallengeRequest and launch the level they will be playing:
{ "@class": ".AcceptChallengeRequest", "challengeInstanceId": "54d0d867e4b021c187559b13" } //Both players will receive a message that Player 2 has accepted the game { "@class": ".ChallengeStartedMessage", "messageId": "54d0db88e4b021c187559cab", "notification": true, "summary": ".ChallengeStartedMessage", "challenge": { "challengeId": "54d0d867e4b021c187559b13", "state": "RUNNING", "scriptData": { "player1Score": "356" }, "shortCode": "asyncChallenge", "startDate": "2015-02-03T14:30Z", "accepted": [ { "name": "oisin", "id": "54d0b768e4b021c187558356" }, { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenged": [ { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenger": { "name": "oisin", "id": "54d0b768e4b021c187558356" }, "expiryDate": null, "endDate": "2015-02-19T00:00Z", "challengeName": "Asynchronous Challenge" }, "playerId": "54d0b761e4b021c187558337" }Player 2 gets a pretty good score, but not good enough to beat Player 1, so we now call our LogChallengeEventRequest:
{ "@class": ".LogChallengeEventRequest", "eventKey": "SetScoreAndCalculateOutcome", "challengeInstanceId": "54d0d867e4b021c187559b13", "score": "212" }Both Players now get either a ChallengeWonMessage or a ChallengeLostMessage:
Player 2 receives:
{ "@class": ".ChallengeLostMessage", "messageId": "54d0dc43e4b021c187559ce0", "notification": true, "summary": ".ChallengeLostMessage", "winnerName": "oisin", "challenge": { "challengeId": "54d0d867e4b021c187559b13", "state": "COMPLETE", "scriptData": { "player1Score": "356", "player2Score": "212" }, "shortCode": "asyncChallenge", "startDate": "2015-02-03T14:30Z", "accepted": [ { "name": "oisin", "id": "54d0b768e4b021c187558356" }, { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenged": [ { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenger": { "name": "oisin", "id": "54d0b768e4b021c187558356" }, "expiryDate": null, "endDate": "2015-02-19T00:00Z", "challengeName": "Asynchronous Challenge" }, "playerId": "54d0b761e4b021c187558337" }Player 1 receives:
{ "@class": ".ChallengeWonMessage", "messageId": "54d0dc43e4b021c187559cdd", "notification": true, "summary": ".ChallengeWonMessage", "currency1Won": 0, "currency2Won": 0, "currency3Won": 0, "currency4Won": 0, "currency5Won": 0, "currency6Won": 0, "challenge": { "challengeId": "54d0d867e4b021c187559b13", "state": "COMPLETE", "scriptData": { "player1Score": "356", "player2Score": "212" }, "shortCode": "asyncChallenge", "startDate": "2015-02-03T14:30Z", "accepted": [ { "name": "oisin", "id": "54d0b768e4b021c187558356" }, { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenged": [ { "name": "shane", "id": "54d0b761e4b021c187558337" } ], "challenger": { "name": "oisin", "id": "54d0b768e4b021c187558356" }, "expiryDate": null, "endDate": "2015-02-19T00:00Z", "challengeName": "Asynchronous Challenge" }, "playerId": "54d0b768e4b021c187558356" }Any questions, just post a reply,
