Is Device Tracked

Updated: Apr 15, 2026
This Blueprint determines whether the tracking system is currently tracking a device such as a controller.

Overview

You pass a device type argument, such as Left Hand, and this Blueprint returns True if the tracking system is tracking that device and False otherwise. For example, if you use the Right Hand controller but not the Left Hand controller, calling this Blueprint with Right Hand returns True. Calling it with Left Hand returns False.
