VRTK_AxisScaleGrabAction

extends VRTK_BaseGrabAction

Overview

Scales the grabbed Interactable Object along the given axes based on the position of the secondary grabbing Interact Grab.

Script Usage:

• Place the VRTK_AxisScaleGrabAction 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 Secondary Grab Action Script parameter to denote use of the secondary grab action.

Inspector Parameters

• Ungrab Distance: The distance the secondary grabbing object must move away from the original grab position before the secondary grabbing object auto ungrabs the Interactable Object.
• Lock Axis: Locks the specified checked axes so they won't be scaled
• Uniform Scaling: If checked all the axes will be scaled together (unless locked)
