Radial Menu Controller

Overview

This adds a UI element into the world space that can be dropped into a Controller object and used to create and use Radial Menus from the touchpad.

If the RadialMenu is placed inside a controller, it will automatically find a VRTK_ControllerEvents in its parent to use at the input. However, a VRTK_ControllerEvents can be defined explicitly by setting the Events parameter of the Radial Menu Controller script also attached to the prefab.

The RadialMenu can also be placed inside a VRTK_InteractableObject for the RadialMenu to be anchored to a world object instead of the controller. The Events Manager parameter will automatically be set if the RadialMenu is a child of an InteractableObject, but it can also be set manually in the inspector. Additionally, for the RadialMenu to be anchored in the world, the RadialMenuController script in the prefab must be replaced with VRTK_IndependentRadialMenuController. See the script information for further details on making the RadialMenu independent of the controllers.

Inspector Parameters

• Events: The controller to listen to the controller events on.

Example

VRTK/Examples/030_Controls_RadialTouchpadMenu displays a radial menu for each controller. The left controller uses the Hide On Release variable, so it will only be visible if the left touchpad is being touched. It also uses the Execute On Unclick variable to delay execution until the touchpad button is unclicked. The example scene also contains a demonstration of anchoring the RadialMenu to an interactable cube instead of a controller.
