Fields

triggerInteraction

Declaration
protected QueryTriggerInteraction triggerInteraction
Field Value
Type Description
QueryTriggerInteraction

Properties

GrabLayerMasks

The LayerMasks, in prioritized order, that are used to determine the touchable objects.

Declaration
public LayerMask[] GrabLayerMasks { get; }
Property Value
Type Description
LayerMask[]
Remarks

Only NearInteractionGrabbables in one of the LayerMasks will raise events.

IgnoreCollidersNotInFOV

Whether to ignore colliders that may be near the pointer, but not actually in the visual FOV. This can prevent accidental grabs, and will allow hand rays to turn on when you may be near a grabbable but cannot see it. Visual FOV is defined by cone centered about display center, radius equal to half display height.

Declaration
public bool IgnoreCollidersNotInFOV { get; set; }
Property Value
Type Description
Boolean

IsInteractionEnabled

Test if the pointer is within the grabbable radius of collider that's both on a grabbable layer mask, and has a NearInteractionGrabbable. Uses SphereCastRadius to determine if near an object. Note: if focus on pointer is locked, will always return true.

Declaration
public override bool IsInteractionEnabled { get; }
Property Value
Type Description
Boolean

True if the pointer is within the grabbable radius of collider that's both on a grabbable layer mask, and has a NearInteractionGrabbable.
Overrides

IsNearObject

Test if the pointer is near any collider that's both on a grabbable layer mask, and has a NearInteractionGrabbable. Uses SphereCastRadius + NearObjectMargin to determine if near an object.

Declaration
public bool IsNearObject { get; }
Property Value
Type Description
Boolean

True if the pointer is near any collider that's both on a grabbable layer mask, and has a NearInteractionGrabbable.

NearObjectMargin

Additional distance on top ofSphereCastRadius when pointer is considered 'near' an object and far interaction will turn off.

Declaration
public float NearObjectMargin { get; }
Property Value
Type Description
Single
Remarks

This creates a dead zone in which far interaction is disabled before objects become grabbable.

NearObjectRadius

Distance at which the pointer is considered "near" an object.

Declaration
public float NearObjectRadius { get; }
Property Value
Type Description
Single
Remarks

Sum of SphereCastRadius and NearObjectMargin. Entering the NearObjectRadius disables far interaction.

SceneQueryBufferSize

Maximum number of colliders that can be detected in a scene query.

Declaration
public int SceneQueryBufferSize { get; }
Property Value
Type Description
Int32

SceneQueryType

The type of physics scene query to use.

Declaration
public override SceneQueryType SceneQueryType { get; set; }
Property Value
Type Description
SceneQueryType
Overrides

TriggerInteraction

Specify whether queries for grabbable objects hit triggers.

Declaration
public QueryTriggerInteraction TriggerInteraction { get; }
Property Value
Type Description
QueryTriggerInteraction

Methods

OnPreSceneQuery()

Called before performing the scene query.

Declaration
public override void OnPreSceneQuery()
Overrides

TryGetDistanceToNearestSurface(out Single)

Near pointers often interact with surfaces.

This method provides a mechanism to get the distance to the closest surface the near pointer is interacting with.

Declaration
public bool TryGetDistanceToNearestSurface(out float distance)
Parameters
Type Name Description
Single distance

Out parameter filled with the distance along the surface normal from the surface to the pointer if available, otherwise 0.0f.
Returns
Type Description
Boolean

True if a distance was retrieved, false if not.

TryGetNearGraspPoint(out Vector3)

Gets the position of where grasp happens For IMixedRealityHand it's the average of index and thumb. For any other IMixedRealityController, return just the pointer origin

Declaration
public bool TryGetNearGraspPoint(out Vector3 result)
Parameters
Type Name Description
Vector3 result
Returns
Type Description
Boolean

TryGetNormalToNearestSurface(out Vector3)

Near pointers often interact with surfaces.

This method provides a mechanism to get the normal of the closest surface the near pointer is interacting with.

Declaration
public bool TryGetNormalToNearestSurface(out Vector3 normal)
Parameters
Type Name Description
Vector3 normal

Out parameter filled with the surface normal if available, otherwise Vector3.zero.
Returns
Type Description
Boolean

True if a normal was retrieved, false if not.
