FarPointer

The far pointer that is interacting with the component

FarRayHitPointInPointer

Far pointer only property -> describes the relative transform of the grab point to the pointer transform (pointer origin / orientation) This is needed to calculate the new grab point on the object on pointer translations / rotations

Declaration
public: FTransform FarRayHitPointInPointer= FTransform::Identity
Field Value
Type Description
FTransform

GrabPointTransform

Last updated grab point transform. (Pointer transform in near pointer case, ray hit transform in far pointer case)

Declaration
public: FTransform GrabPointTransform
Field Value
Type Description
FTransform

GripToGrabPoint

Transform of the grab point in near pointer's grip local space at the start of the interaction.

This is useful to prevent grab point's position changes after grab starts from altering object's transform (e.g. animation of InputSim's hand).

Far pointer doesn't need this because its grip transform is already at grab point.

Declaration
public: FTransform GripToGrabPoint
Field Value
Type Description

GripToObject

Transform of the object in pointer's grip local space at the start of the interaction.

Declaration
public: FTransform GripToObject
Field Value
Type Description
FTransform

LocalGrabPoint

Transform of the pointer when it started interacting, in the local space of the target component. This allows computing pointer offset in relation to the current actor transform.

Declaration
public: FTransform LocalGrabPoint
Field Value
Type Description
FTransform

NearPointer

The near pointer that is interacting with the component.

Declaration
public: UUxtNearPointerComponent * NearPointer= nullptr
Field Value
Type Description
UUxtNearPointerComponent *

StartTime

The time at which interaction started, in seconds since application start.

Declaration
