VRTK_RotatorTrackGrabAttach


> extends [VRTK_TrackObjectGrabAttach](doc:vrtk_trackobjectgrabattach) ## Overview Applies a rotational force to the grabbed Interactable Object. > The Interactable Object is not attached to the grabbing object but rather has a rotational force applied based on the rotation of the grabbing object. **Script Usage:** * Place the `VRTK_RotatorTrackGrabAttach` script on either: * The GameObject of the Interactable Object to detect interactions on. * Any other scene GameObject and then link that GameObject to the Interactable Objects `Grab Attach Mechanic Script` parameter to denote use of the grab mechanic. ## Class Methods ### StopGrab/1 > `public override void StopGrab(bool applyGrabbingObjectVelocity)` * Parameters * `bool applyGrabbingObjectVelocity` - If `true` will apply the current velocity of the grabbing object to the grabbed Interactable Object on release. * Returns * _none_ The StopGrab method ends the grab of the current Interactable Object and cleans up the state. ### ProcessFixedUpdate/0 > `public override void ProcessFixedUpdate()` * Parameters * _none_ * Returns * _none_ The ProcessFixedUpdate method is run in every FixedUpdate method on the Interactable Object. It applies a force to the grabbed Interactable Object to move it in the direction of the grabbing object. ## Example `VRTK/Examples/021_Controller_GrabbingObjectsWithJoints` demonstrates this grab attach mechanic on the Wheel and Door objects in the scene.
