Creating AR UI elements

In the previous chapter, we also implemented an InstructionElement abstract class that we subclass for each of the content types: title, body, image, and video. We will now make a similar one for the AR graphic content.

Technically, the graphic is not a UI one because it's going to be displayed in 3D world space, not 2D screen space like the other instruction content. But it fits nicely with our architecture design because we can load it from CSV like other content, and can broadcast its updates like other UI content when the user changes steps.

In your Scripts/UIElements/ folder, create a C# script named ARGraphic and write it as follows:

File: ARGraphic.cs using UnityEngine; public class ARGraphic : InstructionElement ...
