World Space Health Bars That Follow Units | Unity Tutorial

Learn how to make Health Bars that stay above the heads of units in World Space!
A common need in games is to show Health Bars over some enemy or unit. In this tutorial we'll take a look at one way to achieve that in a way that enables us to retain the benefits of sliced and filled Sprites.

I also discuss some of the "gotchas" that you may encounter as you implement this in terms of both performance and strange behaviors.

As usual when we use a NavMesh, we're using the NavMesh Components: https://docs.unity3d.com/Manual/NavMe... not the built-in navigation system.
