Generate player IDs
Amazon GameLift Servers uses a player session to represent a player connected to a game session. Amazon GameLift Servers creates a player session each time a player connects to a game session using a game client integrated with Amazon GameLift Servers. When a player leaves a game, the player session ends. Amazon GameLift Servers doesn't reuse player sessions.
Important
When using FlexMatch matchmaking, if you create a new matchmaking request that contains a player ID that is already included in an existing active matchmaking request, the existing request is automatically cancelled. However, a MatchmakingCancelled event is not sent for the cancelled request. To monitor the status of existing matchmaking requests, use DescribeMatchmaking to poll the request status at infrequent intervals (30-60 seconds). The cancelled request will show a status of CANCELLED with the reason Cancelled due to duplicate player.
The following code example randomly generates unique player IDs:
bool includeBrackets = false; bool includeDashes = true; string playerId = AZ::Uuid::CreateRandom().ToString<string>(includeBrackets, includeDashes);
For more information about player sessions, see Game and player sessions in the Amazon GameLift Servers console.
