Duration Control (China)

Games sold in mainland China must limit the playtime of minors. Steam tracks the playtime and tells the game when the player should stop. The nodes are called on Get Steam User and are in the SteamCore|User category.

Duration control only applies to players and games where Steam has enabled it. For everyone else, bApplicable is false and the game doesn't need to do anything.

Getting the Status

Call Get Duration Control. It is async and is also available as an async node in the SteamCore|User|Async category. Data contains:

Field	Description
bApplicable	Whether duration control applies to this player and game.
Progress	Full while the player may keep playing. Exit Soon 3h, Exit Soon 5h and Exit Soon Night mean the limit has been reached and Steam will close the game soon.
Seconds Today	Playtime today.
Seconds Remaining	Playtime left before a limit is reached.
Seconds Last 5h	Playtime since the last 5-hour break.

Notifications

Steam also sends updates on its own while the game is running. Bind to the Duration Control Updated delegate on Get Steam User. When Notification is set, show it to the player. When Progress is one of the Exit Soon values, save the game and tell the player that the game will close.

Offline Play

Offline play does not count against the limits. Call Set Duration Control Online State when the player switches between offline and online play:

State	Use it for
Offline	Single-player or offline co-op.
Online	Online play.
Online High Pri	Online play that shouldn't be interrupted, for example a ranked match.
