One of the biggest obstacles to developing for the Oculus is simulating mouse.

This post will take us through the first of three basic steps to get Oculus mouse integration working.

Well create a 3d mouse-object that follows the mouse-movement.

Next time well add click-integration using triggers in post 2 and well finish with click-integration for Coherent UI web views.

There are a couple of very good reasons why we cant just use the mouse the normal Unity way.

Thats right. Were gonna take a Unity asset and turn it into our pointer with a few simple scripting tricks.

I use a red sphere-object as default but you can use whatever works for you.

Should have something for you to try around the 2019.3 release.

In-game support and visual authoring will come in future releases.

IMGUI makes it easy to start building user interfaces but fails to scale when youre building more complex applications.

Its also difficult for the system to optimize rendering because the user can drastically change the structure of the UI at any time within the current frame.

This way, the system can optimize what it draws, and when it draws, leading to better overall performance.

This paradigm also lets you decouple your hierarchy and styling from functionality, which results in a better separation of concerns and more approachable UI authoring for both artists and programmers.

Individual VisualElement s can be parented to each other to form your UI hierarchy.

Layouting, styling, and other systems then traverse this hierarchy to properly render your UI to screen.

Elements need to be added as children to this root in order for the system to know about them and draw them.

UIElements; public class ExampleWindow: EditorWindow public void OnEnable ( ) var root this.

This is where retained mode differs from immediate mode the most.

The developer only needs to declare what should happen, and when, but doesnt need to manage the frame-to-frame rendering.

In C, you can focus on just binding your declared UI with functionality and data using the built-in query system and event system.

This will make it easier for all users to tweak, author, and design UI in Unity.

However, just like styles, most of your hierarchy wont change very much throughout the lifetime of your UI.

Therefore, we recommend that you modularize your UI by defining your hierarchy in a separate XML-based asset called UXML.

Attributes will be set on the new elements on creation, and nested tags will become children of their parent tag.

You can then instantiate (or clone) this VisualTreeAsset under any element and as many times as you wish.

LoadAssetAtPath VisualTreeAsset ( AssetsExampleUI.uxml ); uxml.

CloneTree ( root ); Create the tags in uxml as children of root.

However, since most styles are statically defined, it makes sense to separate their descriptions from the UI logic in C.

UIElements uses Unity-specific StyleSheet assets, called USS, which uses a subset of the CSS standard.

You can use the same selectors familiar from CSS to identify which elements should get which styles, while the styles themselves are key-value pairs.

You can then assign it to your desired element and it will automatically apply the styles within to this element, as well as all its children.

If children are added afterward, the styles will be applied to them as well.
