2018/02/08 - Amazon GameLift - 1 new 8 updated api methods
Changes Amazon GameLift FlexMatch added the StartMatchBackfill API. This API allows developers to add new players to an existing game session using the same matchmaking rules and player data that were used to initially create the session.
Finds new players to fill open slots in an existing game session. This operation can be used to add players to matched games that start with fewer than the maximum number of players or to replace players when they drop out. By backfilling with the same matchmaker used to create the original match, you ensure that new players meet the match criteria and maintain a consistent experience throughout the game session. You can backfill a match anytime after a game session has been created.
To request a match backfill, specify a unique ticket ID, the existing game session's ARN, a matchmaking configuration, and a set of data that describes all current players in the game session. If successful, a match backfill ticket is created and returned with status set to QUEUED. The ticket is placed in the matchmaker's ticket pool and processed. Track the status of the ticket to respond as needed. For more detail how to set up backfilling, see Set up Match Backfilling .
The process of finding backfill matches is essentially identical to the initial matchmaking process. The matchmaker searches the pool and groups tickets together to form potential matches, allowing only one backfill ticket per potential match. Once the a match is formed, the matchmaker creates player sessions for the new players. All tickets in the match are updated with the game session's connection information, and the GameSession object is updated to include matchmaker data on the new players. For more detail on how match backfill requests are processed, see How Amazon GameLift FlexMatch Works .

{'GameSession': {'MatchmakerData': 'string'}}
Creates a multiplayer game session for players. This action creates a game session record and assigns an available server process in the specified fleet to host the game session. A fleet must have an ACTIVE status before a game session can be created in it.
To create a game session, specify either fleet ID or alias ID and indicate a maximum number of players to allow in the game session. You can also provide a name and game-specific properties for this game session. If successful, a GameSession object is returned containing the game session properties and other settings you specified.
Idempotency tokens. You can add a token that uniquely identifies game session requests. This is useful for ensuring that game session requests are idempotent. Multiple requests with the same idempotency token are processed only once; subsequent requests return the original result. All response values are the same with the exception of game session status, which may change.
Resource creation limits. If you are creating a game session on a fleet with a resource creation limit policy in force, then you must specify a creator ID. Without this ID, Amazon GameLift has no way to evaluate the policy for this new game session request.
Player acceptance policy. By default, newly created game sessions are open to new players. You can restrict new player access by using UpdateGameSession to change the game session's player session creation policy.
Game session logs. Logs are retained for all active game sessions for 14 days. To access the logs, call GetGameSessionLogUrl to download the log files.

{'GameSessions': {'MatchmakerData': 'string'}}
Retrieves all active game sessions that match a set of search criteria and sorts them in a specified order. You can search or sort by the following game session attributes:
gameSessionId -- Unique identifier for the game session. You can use either a GameSessionId or GameSessionArn value.
gameSessionName -- Name assigned to a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession . Game session names do not need to be unique to a game session.
gameSessionProperties -- Custom data defined in a game session's GameProperty parameter. GameProperty values are stored as key:value pairs; the filter expression must indicate the key and a string to search the data values for. For example, to search for game sessions with custom data containing the key:value pair "gameMode:brawl", specify the following: gameSessionProperties.gameMode = "brawl". All custom data values are searched as strings.
maximumSessions -- Maximum number of player sessions allowed for a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession .
creationTimeMillis -- Value indicating when a game session was created. It is expressed in Unix time as milliseconds.
playerSessionCount -- Number of players currently connected to a game session. This value changes rapidly as players join the session or drop out.
hasAvailablePlayerSessions -- Boolean value indicating whether a game session has reached its maximum number of players. It is highly recommended that all search requests include this filter attribute to optimize search performance and return only sessions that players can join.
Note
Returned values for playerSessionCount and hasAvailablePlayerSessions change quickly as players join sessions and others drop out. Results should be considered a snapshot in time. Be sure to refresh search results often, and handle sessions that fill up before a player can join.
To search or sort, specify either a fleet ID or an alias ID, and provide a search filter expression, a sort expression, or both. If successful, a collection of GameSession objects matching the request is returned. Use the pagination parameters to retrieve results as a set of sequential pages.
You can search for game sessions one fleet at a time only. To find game sessions across multiple fleets, you must search each fleet separately and combine the results. This search feature finds only game sessions that are in ACTIVE status. To locate games in statuses other than active, use DescribeGameSessionDetails .

)
string
Unique identifier for a fleet to search for active game sessions. Each request must reference either a fleet ID or alias ID, but not both.
string
Unique identifier for an alias associated with the fleet to search for active game sessions. Each request must reference either a fleet ID or alias ID, but not both.
string
String containing the search criteria for the session search. If no filter expression is included, the request returns results for all game sessions in the fleet that are in ACTIVE status.
A filter expression can contain one or multiple conditions. Each condition consists of the following:
Operand -- Name of a game session attribute. Valid values are gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .
Comparator -- Valid comparators are: = , <> , < , > , <= , >= .
Value -- Value to be searched for. Values may be numbers, boolean values (true/false) or strings depending on the operand. String values are case sensitive and must be enclosed in single quotes. Special characters must be escaped. Boolean and string values can only be used with the comparators = and <> . For example, the following filter expression searches on gameSessionName : "FilterExpression": "gameSessionName = 'Matt\\'s Awesome Game 1'" .
To chain multiple conditions in a single expression, use the logical keywords AND , OR , and NOT and parentheses as needed. For example: x AND y AND NOT z , NOT (x OR y) .
Session search evaluates conditions from left to right using the following precedence rules:
= , <> , < , > , <= , >=
Parentheses
NOT
AND
OR
For example, this filter expression retrieves game sessions hosting at least ten players that have an open player slot: "maximumSessions>=10 AND hasAvailablePlayerSessions=true" .
string
Instructions on how to sort the search results. If no sort expression is included, the request returns results in random order. A sort expression consists of the following elements:
Operand -- Name of a game session attribute. Valid values are gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .
Order -- Valid sort orders are ASC (ascending) and DESC (descending).
For example, this sort expression returns the oldest active sessions first: "SortExpression": "creationTimeMillis ASC" . Results with a null value for the sort operand are returned at the end of the list.
integer
Maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages. The maximum number of results returned is 20, even if this value is not set or is set higher than 20.
string
Token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this action. To start at the beginning of the result set, do not specify a value.

{'GameSessionPlacement': {'MatchmakerData': 'string'}}
Places a request for a new game session in a queue (see CreateGameSessionQueue ). When processing a placement request, Amazon GameLift searches for available resources on the queue's destinations, scanning each until it finds resources or the placement request times out.
A game session placement request can also request player sessions. When a new game session is successfully created, Amazon GameLift creates a player session for each player included in the request.
When placing a game session, by default Amazon GameLift tries each fleet in the order they are listed in the queue configuration. Ideally, a queue's destinations are listed in preference order.
Alternatively, when requesting a game session with players, you can also provide latency data for each player in relevant regions. Latency data indicates the performance lag a player experiences when connected to a fleet in the region. Amazon GameLift uses latency data to reorder the list of destinations to place the game session in a region with minimal lag. If latency data is provided for multiple players, Amazon GameLift calculates each region's average lag for all players and reorders to get the best game play across all players.
To place a new game session request, specify the following:
The queue name and a set of game session properties and settings
A unique ID (such as a UUID) for the placement. You use this ID to track the status of the placement request
(Optional) A set of IDs and player data for each player you want to join to the new game session
Latency data for all players (if you want to optimize game play for the players)
If successful, a new game session placement is created.
To track the status of a placement request, call DescribeGameSessionPlacement and check the request's status. If the status is FULFILLED , a new game session has been created and a game session ARN and region are referenced. If the placement request times out, you can resubmit the request or retry it with a different queue.
