XRStats.TryGetStat

Parameters

Returns

bool True, if the requested statistic is available, false otherwise.

Description

Retrieve a statistic for an XR subsystem.

The TryGetStat method queries an XR subsystem for the specified statistic and, if available, sets the output value parameter to the current statistic value. TryGetStat returns true to indicate that the output parameter contains a valid statistic value. If the specified tag is not defined for the subsystem or the subsystem itself is not ready, TryGetStat returns false.
