Controller Tooltips

Overview

Adds a collection of Object Tooltips to the Controller providing information to what the controller buttons may do.

Prefab Usage:

  • Place the VRTK/Prefabs/ControllerTooltips/ControllerTooltips prefab as a child of the relevant controller script alias GameObject in the scene hierarchy.
  • If no Button Transform Settings are provided in the inspector at Edit time then the button transforms will attempt to be set to the transforms of the current SDK default controller model.
  • If one of the Button Text Settings text options are not provided, then the tooltip for that specific button will be hidden.

There are a number of parameters that can be set on the Prefab which are provided by the VRTK_ControllerTooltips script which is applied to the prefab.

  • Trigger Text: The text to display for the trigger button action.
  • Grip Text: The text to display for the grip button action.

  • Touchpad Two Text: The text to display for the touchpad two action.
  • Button One Text: The text to display for button one action.

Unity Events

Adding the VRTK_ControllerTooltips_UnityEvents component to VRTK_ControllerTooltips object allows access to UnityEvents that will react identically to the Class Events.

  • All C# delegate events are mapped to a Unity Event with the On prefix. e.g. MyEvent -> OnMyEvent.
