Configuration #
FriendsServiceConfig #
The FriendsServiceConfig
configuration block provides a place to define default values for the Friend and Presence services.
Note about GDPR compliance: Setting yourmaxTimeBetweenAccessMillis
to a value over 30 days (2592000000 milliseconds) may result in GDPR noncompliance, as user data may exist in the cache untilmaxTimeBetweenAccessMillis
is reached.
The following configuration values are related to Friends features:
config | description |
---|---|
maxFriendsListSize | Maximum number of friends an individual player can maintain Default: 400 |
maxPendingSentInvites | Maximum number of pending (unresponded to) sent invites an inviter can maintain before oldest pending invites are removed to make room for newer invites. If a player attempts to send a friend invite when their pending sent invite list is full, the oldest pending sent invite in their list will be deleted. A “sent invite removed” event is triggered for the inviter, and a “received invite removed” event is triggered for the invitee. Default: 20 |
maxPendingReceivedInvites | Maximum number of pending (unresponded to) received invites a player can maintain before subsequent invites are automatically rejected. If a player attempts to send a friend invite to a player whose received invites list is full, the inviter will receive an INVITEE_RECEIVED_INVITES_FULL error. Default: 20 |
See Presence Reference for information on other configuration values.
