VRTK_DragWorld

Overview

Provides the ability to move, rotate and scale the PlayArea by dragging the world with the controllers.

Script Usage:

• Place the VRTK_DragWorld script on any active scene GameObject.

If only one controller is being used to track the rotation mechanism, then the rotation will be based on the perpendicual (yaw) axis angular velocity of the tracking controller.
If both controllers are being used to track the rotation mechanism, then the rotation will be based on pushing one controller forward, whilst pulling the other controller backwards.

Inspector Parameters

• Movement Activation Button: The controller button to press to activate the movement mechanism.
• Movement Activation Requirement: The controller(s) on which the activation button is to be pressed to consider the movement mechanism active.
• Movement Tracking Controller: The controller(s) on which to track position of to determine if a valid move has taken place.
• Movement Multiplier: The amount to multply the movement by.
• Movement Position Lock: The axes to lock to prevent movement across.
• Rotation Activation Button: The controller button to press to activate the rotation mechanism.
• Rotation Activation Requirement: The controller(s) on which the activation button is to be pressed to consider the rotation mechanism active.
• Rotation Tracking Controller: The controller(s) on which to determine how rotation should occur. BothControllers requires both controllers to be pushed/pulled to rotate, whereas any other setting will base rotation on the rotation of the activating controller.
• Rotation Multiplier: The amount to multply the rotation angle by.
• Rotation Activation Threshold: The threshold the rotation angle has to be above to consider a valid rotation amount.
• Scale Activation Button: The controller button to press to activate the scale mechanism.
• Scale Activation Requirement: The controller(s) on which the activation button is to be pressed to consider the scale mechanism active.
• Scale Tracking Controller: The controller(s) on which to determine how scaling should occur.
• Scale Multiplier: The amount to multply the scale factor by.
• Scale Activation Threshold: The threshold the distance between the scale objects has to be above to consider a valid scale operation.
• Minimum Scale: the minimum scale amount that can be applied.
• Maximum Scale: the maximum scale amount that can be applied.
• Controlling Transform: The transform to apply the control mechanisms to. If this is left blank then the PlayArea will be controlled.
• Use Offset Transform: Uses the specified Offset Transform when dealing with rotational offsets.
• Offset Transform: The transform to use when dealing with rotational offsets. If this is left blank then the Headset will be used as the offset.

Class Variables

• public enum ActivationRequirement - The controller on which to determine as the activation requirement for the control mechanism.
  • LeftControllerOnly - Only pressing the activation button on the left controller will activate the mechanism, if the right button is held down then the mechanism will not be activated.
  • RightControllerOnly - Only pressing the activation button on the right controller will activate the mechanism, if the left button is held down then the mechanism will not be activated.
  • LeftController - Pressing the activation button on the left controller is all that is required to activate the mechanism.
  • RightController - Pressing the activation button on the right controller is all that is required to activate the mechanism.
  • EitherController - Pressing the activation button on the either controller is all that is required to activate the mechanism.
  • BothControllers - Pressing the activation button on both controllers is required to activate the mechanism.
• public enum TrackingController - The controllers which to track when performing the mechanism.
  • LeftController - Only track the left controller.
  • RightController - Only track the right controller.
  • EitherController - Track either the left or the right controller.
  • BothControllers - Only track both controllers at the same time.
