Instant Tournaments for Instant Games

FBInstant

Top level namespace for the Instant Games SDK.

postSessionScore( )

Note: this API is deprecated.

Posts a player's score to Facebook. This API should only be called at the end of an activity (example: when the player doesn't have "lives" to continue the game). This API will be rate-limited when called too frequently. Scores posted using this API should be consistent and comparable across game sessions. For example, if Player A achieves 200 points in a session, and Player B achieves 320 points in a session, those two scores should be generated from activities where the scores are fair to be compared and ranked against each other.

Parameters

  • score number An integer value representing the player's score at the end of an activity.

Examples

function onScore(score) {
  if (score > bestSessionScore) {
    bestSessionScore = score;
    FBInstant.postSessionScore(bestSessionScore);
  }
}

Returns void

postSessionScoreAsync( )

Posts a player's score to Facebook and resolves when score has been posted. This API should only be called at the end of an activity (example: when the player doesn't have "lives" to continue the game). This API will be rate-limited when called too frequently. Scores posted using this API should be consistent and comparable across game sessions. For example, if Player A achieves 200 points in a session, and Player B achieves 320 points in a session, those two scores should be generated from activities where the scores are fair to be compared and ranked against each other.

Parameters

  • score number An integer value representing the player's score at the end of an activity.

Examples

function onScore(score) {
  if (score > bestSessionScore) {
    bestSessionScore = score;
    FBInstant.postSessionScoreAsync(bestSessionScore)
      .then(() => {
        ...
      });
  }
}

Returns Promise A promise that resolves when all platform behavior (such as dialogs) generated from the posted score has completed, and the game should resume. If the behavior resulted in a social context change, that will be reflected by the time the Promise resolves.

Tournament

An instant game tournament.

getID( )

The unique ID that is associated with this instant tournament.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
    console.log(tournament.getID());
  });

Returns string A unique identifier for the instant tournament.

getContextID( )

The unique context ID that is associated with this instant tournament.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
    console.log(tournament.getContextID());
  });

Returns string A unique identifier for the game context.

getEndTime( )

Timestamp when the instant tournament ends. If the end time is in the past, then the instant tournament is already finished and has expired.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
    console.log(tournament.getEndTime());
  });

Returns number A unix timestamp of when the tournament will end.

getTitle( )

Title of the tournament provided upon the creation of the tournament. This is an optional field that can be set by creating the tournament using the FBInstant.tournament.createAsync() API.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
    console.log(tournament.getTitle());
  })

Returns string?

getPayload( )

Payload of the tournament provided upon the creation of the tournament. This is an optional field that can be set by creating the tournament using the FBInstant.tournament.createAsync() API.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
    console.log(tournament.getPayload());
  })

Returns string?

getTournamentAsync( )

Fetch the instant tournament out of the current context the user is playing. This will reject if there is no instant tournament link to the current context. The instant tournament returned can be either active or expired (An instant tournament is expired if its end time is in the past). For each instant tournament, there is only one unique context ID linked to it, and that ID doesn't change.

Examples

FBInstant.getTournamentAsync()
  .then(function(tournament) {
     console.log(tournament.getContextID());
     console.log(tournament.getEndTime());
  });
