Tilia Unity UI Unity Editor 2017 +

Unity UI with UI Pointers.

Introduction

Support for Unity UI. Both New and Old input systems

Requires Unity Editor 2017.4 +

Use cases:

This package only covers:

• use case with a UI layer for casting UI elements.
• 3d casting on world object to enable support for default Unity Event Triggers

Setup:

1. Place VRTK4_UICanvas on each canvas

   • ON ALL UI ELEMENTS - buttons, sliders, inputfields, toggles, dropdown -> YOU MUST REMOVE DEFAULT UNITY NAVIGATION (navigation = none)!
   • You may leave Blocking mask as None (this way you will save on performance - no 3D raycasts will be performed)

2. If you need drag and drop functionality on the UI: enable supportDragAndDropUI on the VRTK4_UICanvas (use custom gameobject with name CANVAS_DRAGGABLE_PANEL, or default one will generated). Note : default CANVAS_DRAGGABLE_PANEL is placed first,it will block all previous canvases or canvases that are behind it.

3. To ignore player objects : use component VRTK4_PlayerObject

4. If you are using Pseudobody - add pointers to the IgnoredGameObjectList

5. Just as with standart unity 3D raycasting (enabling cast on world objects) : Add VRTK4_3DGraphicRaycaster and setup interactive layers. See here :

Other important notes:

• When using animations on the UI canvas: add box collider on it in Editor mode, otherwise UI colliders are created at the Awake, with canvas delta size ( example animation from small to large size).

• When using Unity Event Triggers: pointers will always perform their separate OnEnter/OnExit -> so please see TiliaUnityEventTriggerSubscriber correct usage script

• All input fields must hide soft keyboard and hide mobile input. There is no default keyboard in this package. Please use custom one.

• When using input fields: VR + Input field caret is not working properly. Make sure to use custom caret script. Example see here -> https://gist.github.com/studentutu/714d78ad6cebfe147bfa852fb7046a90
