Declaration

public static bool TryGetStat(IntegratedSubsystem xrSubsystem, string tag, out float value);

Parameters

xrSubsystem The subsystem with which the stat is registered.
tag The tag used to query for a statistic.
value Receives the current value of the requested statistic. Contains a valid value when this method returns true.

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.
