Container for the parameters to the StartMatchmaking operation. Uses FlexMatch to create a game match for a group of players based on custom matchmaking rules, and starts a new game for the matched players. Each matchmaking request specifies the type of match to build (team configuration, rules for an acceptable match, etc.). The request also specifies the players to find a match for and where to host the new game session for optimal performance. A matchmaking request might start with a single player or a group of players who want to play together. FlexMatch finds additional players as needed to fill the match. Match type, rules, and the queue used to place a new game session are defined in a MatchmakingConfiguration. For complete information on setting up and using FlexMatch, see the topic Adding FlexMatch to Your Game.

To start matchmaking, provide a unique ticket ID, specify a matchmaking configuration, and include the players to be matched. You must also include a set of player attributes relevant for the matchmaking configuration. If successful, a matchmaking ticket is returned with status set to QUEUED. Track the status of the ticket to respond as needed and acquire game session connection information for successfully completed matches.

Tracking ticket status -- A couple of options are available for tracking the status of matchmaking requests:

Processing a matchmaking request -- FlexMatch handles a matchmaking request as follows:

  1. Your client code submits a StartMatchmaking request for one or more players and tracks the status of the request ticket.

  2. FlexMatch uses this ticket and others in process to build an acceptable match. When a potential match is identified, all tickets in the proposed match are advanced to the next status.

  3. If the match requires player acceptance (set in the matchmaking configuration), the tickets move into status REQUIRES_ACCEPTANCE. This status triggers your client code to solicit acceptance from all players in every ticket involved in the match, and then call AcceptMatch for each player. If any player rejects or fails to accept the match before a specified timeout, the proposed match is dropped (see AcceptMatch for more details).

  4. Once a match is proposed and accepted, the matchmaking tickets move into status PLACING. FlexMatch locates resources for a new game session using the game session queue (set in the matchmaking configuration) and creates the game session based on the match data.

  5. When the match is successfully placed, the matchmaking tickets move into COMPLETED status. Connection information (including game session endpoint and player session) is added to the matchmaking tickets. Matched players can use the connection information to join the game.
