Get Node Guardian Intersection
This Blueprint returns the intersection between a tracked device (HMD or Controller) and the Guardian boundary.
This Blueprint only works with the Oculus Rift, since it retrieves information related to Guardian. It is only meaningful when positional tracking is available and the product provides 6DOF (six degrees of freedom) support.
This Blueprint returns the intersection between a tracked device (HMD or Controller) and the Guardian boundary.
- Device Type: An enum representing the type of device you want to retrieve the intersection with the Guardian on. You can set this value to:
- No Devices: Tells the system that it shouldn’t check any devices to see if they are currently intersecting the Guardian.
- HMD: Checks the head position to see if it is currently intersecting the Guardian.
- Left Hand: Checks the position of the controller associated with the left hand to see if it is currently intersecting the Guardian.
- Right Hand: Checks the position of the controller associated with the right hand to see if it is currently intersecting the Guardian.
- All Hands: Checks the position of both controllers (left and right hands) to see if either is currently intersecting the Guardian.
- Device Object Zero: Checks if a camera tracked by the sensors currently intersects the guardian. The mixed reality feature uses an external camera. In this scenario, the user attaches a Touch controller to the camera, and the sensors then track the camera by tracking the Touch controller.
- All Devices: Checks all available devices to see if any are intersecting the Guardian.
- Boundary Type: An enum representing the type of guardian boundary the system should check against. You may set this value to:
- Outer Boundary: The exact bounds of the Guardian area.
- Play Area: A rectangle within the Outer Boundary.
- Return Value: A Guardian Test Result structure that specifies the intersection between the node and the selected guardian boundary. This structure contains the following fields:
- Is Triggering: A boolean indicating whether a triggering interaction exists between the node and guardian boundary.
- Device Type: An
ETrackedDeviceTypeEnum that specifies the type of device that is triggering the boundary. - Closest Distance: The distance of the node from the boundary.
- Closest Point: The closest point to the node that resides on the surface of the specified boundary.
- Closest Point Normal: The geometrical normal vector for the Closest Point relative to the boundary surface.
