Actions
|
Clear XRTimed Input Action Delegate |
/ Clear a delegate to get an OpenXR action event with action time. Target is Head Mounted Display Function Library |
|
Configure Gestures |
Specify which gestures to capture. Target is Head Mounted Display Function Library |
|
Enumerate Tracked Devices |
Cross XR-System query that will list all XR devices currently being tracked. Target is Head Mounted Display Function Library |
|
Get Controller Transform for Time |
Get the transform and potentially velocity data at a specified time near the current frame in unreal world space. This is intended for use with sub-frame input action timing data from SetXRTimedInputActionDelegate, or future support for timestamps in the core input system. The valid time window is platform dependent, but the intention per OpenXR is to fetch transforms for times from, at most, the previous few frames in the past or future. The OpenXR spec suggests that 50ms in the past should return an accurate result. There is no guarantee for the future, but the underlying system is likely to have been designed to predict out to about 50ms as well. On some platforms this will always just return a cached position and rotation, ignoring time. bTimeWasUsed will be false in that case. Target is Head Mounted Display Function Library |
|
Get Device Pose |
Cross XR-System query that returns a specific device's tracked position and orientation (in tracking space). Target is Head Mounted Display Function Library |
|
Get Device World Pose |
Cross XR-System query that returns a specific device's position and orientation in world space. Target is Head Mounted Display Function Library |
|
Get HMDData |
Cross XR-System query that returns critical information about the HMD display (position, orientation, device name) Target is Head Mounted Display Function Library |
|
Get Motion Controller Data |
Cross XR-System query that returns critical information about the motion controller (position, orientation, hand/finger position) Target is Head Mounted Display Function Library |
|
Get Play Area Bounds |
Get the bounds of the area where the user can freely move while remaining tracked centered around the specified origin Target is Head Mounted Display Function Library |
|
Is Device Tracking |
Cross XR-System query that returns whether the specified device is tracked or not. Target is Head Mounted Display Function Library |
|
Render HMD |
Renders HMD Visualization on a system that might not have that HMD as native Target is XRVisualization Function Library |
|
Render Motion Controller |
Renders Motion Controller Visualization on a system that might not have that HMD as native Target is XRVisualization Function Library |
|
Set XRTimed Input Action Delegate |
Hook up a delegate to get an OpenXR action event with action time. For a boolean input the the 'value' parameter of the delegate will be 1.0 for a press and 0.0 for a release. For an analog input the value's range is action and platform specific. Use in combination with GetControllerTransformForTime for potentially improved temporal transform precision and velocity data. "Left Grip" is an example of a valid ActionName. Note: this is likely to be replaced by native support for event times in the core input system at some time in the future.
