VRTK_ChildOfControllerGrabAttach

extends VRTK_BaseGrabAttach

Overview

The Child Of Controller Grab Attach script is used to make the grabbed object a child of the grabbing object upon grab.

The object upon grab will naturally track the position and rotation of the grabbing object as it is a child of the grabbing game object.

The rigidbody of the object will be set to kinematic upon grab and returned to it's original state on release.

Class Methods

StartGrab/3

public override bool StartGrab(GameObject grabbingObject, GameObject givenGrabbedObject, Rigidbody givenControllerAttachPoint)

• Parameters
• GameObject grabbingObject - The object that is doing the grabbing.
• GameObject givenGrabbedObject - The object that is being grabbed.
• Rigidbody givenControllerAttachPoint - The point on the grabbing object that the grabbed object should be attached to after grab occurs.
• Returns
• bool - Is true if the grab is successful, false if the grab is unsuccessful.

The StartGrab method sets up the grab attach mechanic as soon as an object is grabbed. It is also responsible for creating the joint on the grabbed object.

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 object on release.
• Returns

The StopGrab method ends the grab of the current object and cleans up the state.
