Utilizing World Space UI
In Chapter 6, we discussed the three different Render Modes you can assign to a Canvas. We’ve used Screen Space-Overlay and Screen Space-Camera but haven’t used World Space yet. As described in Chapter 2, UI rendered in World Space is placed directly in the scene. We’ve already discussed the properties of World Space Canvas rendering, so this chapter will just look at when to use it and examples of implementation.
In this chapter, we will discuss the following topics:
- When to use World Space UI
- General techniques to consider when working with World Space UI
- Using World Space Canvases in a 2D game to create status indicators positioned relative to characters
- Using World Space Canvases to create health bars that hover over enemies’ heads in a 3D game
