Radial Menu

## 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 * **Buttons:** An array of Buttons that define the interactive buttons required to be displayed as part of the radial menu. * **Button Prefab:** The base for each button in the menu, by default set to a dynamic circle arc that will fill up a portion of the menu. * **Generate On Awake:** If checked, then the buttons will be auto generated on awake. * **Button Thickness:** Percentage of the menu the buttons should fill, 1.0 is a pie slice, 0.1 is a thin ring. * **Button Color:** The background colour of the buttons, default is white. * **Offset Distance:** The distance the buttons should move away from the centre. This creates space between the individual buttons. * **Offset Rotation:** The additional rotation of the Radial Menu. * **Rotate Icons:** Whether button icons should rotate according to their arc or be vertical compared to the controller. * **Icon Margin:** The margin in pixels that the icon should keep within the button. * **Is Shown:** Whether the buttons are shown * **Hide On Release:** Whether the buttons should be visible when not in use. * **Execute On Unclick:** Whether the button action should happen when the button is released, as opposed to happening immediately when the button is pressed. * **Base Haptic Strength:** The base strength of the haptic pulses when the selected button is changed, or a button is pressed. Set to zero to disable. * **Menu Buttons:** The actual GameObjects that make up the radial menu. ## Class Methods ### HoverButton/1 > `public virtual void HoverButton(float angle)` * Parameters * `float angle` - The angle on the radial menu. * Returns * _none_ The HoverButton method is used to set the button hover at a given angle. ### ClickButton/1 > `public virtual void ClickButton(float angle)` * Parameters * `float angle` - The angle on the radial menu. * Returns * _none_ The ClickButton method is used to set the button click at a given angle. ### UnClickButton/1 > `public virtual void UnClickButton(float angle)` * Parameters * `float angle` - The angle on the radial menu. * Returns * _none_ The UnClickButton method is used to set the button unclick at a given angle. ### ToggleMenu/0 > `public virtual void ToggleMenu()` * Parameters * _none_ * Returns * _none_ The ToggleMenu method is used to show or hide the radial menu. ### StopTouching/0 > `public virtual void StopTouching()` * Parameters * _none_ * Returns * _none_ The StopTouching method is used to stop touching the menu. ### ShowMenu/0 > `public virtual void ShowMenu()` * Parameters * _none_ * Returns * _none_ The ShowMenu method is used to show the menu. ### GetButton/1 > `public virtual RadialMenuButton GetButton(int id)` * Parameters * `int id` - The id of the button to retrieve. * Returns * `RadialMenuButton` - The found radial menu button. The GetButton method is used to get a button from the menu. ### HideMenu/1 > `public virtual void HideMenu(bool force)` * Parameters * `bool force` - If true then the menu is always hidden. * Returns * _none_ The HideMenu method is used to hide the menu. ### RegenerateButtons/0 > `public void RegenerateButtons()` * Parameters * _none_ * Returns * _none_ The RegenerateButtons method creates all the button arcs and populates them with desired icons. ### AddButton/1 > `public void AddButton(RadialMenuButton newButton)` * Parameters * `RadialMenuButton newButton` - The button to add. * Returns * _none_ The AddButton method is used to add a new button to the menu. ## 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.
