Method TryAddRaycast
TryAddRaycast(Vector2, float, out XRRaycast)
Attempts to add a new persistent raycast. The raycast will be updated automatically until this subsystem is stopped or destroyed, or the the raycast is removed with RemoveRaycast(TrackableId).
Declaration
public bool TryAddRaycast(Vector2 screenPoint, float estimatedDistance, out XRRaycast raycast)Parameters
| Type | Name | Description |
|---|---|---|
| Vector2 | screenPoint | A point on the screen, in normalized screen coorindates (0, 0)..(1, 1). |
| float | estimatedDistance | The estimated distance to the raycast target. For example, an average human height might be used to estimate the distance to the floor. |
| XRRaycast | raycast | The newly added raycast. All spatial data is relative to the XR origin. |
Returns
| Type | Description |
|---|---|
| bool |
