This asset pack was designed to make health bar integration as simple as possible. It offers the following health bars: vertical rectangle, horizontal rectangle, half circle, and full circle. It also contains a world space health bar that moves with the game object it is attached to (great for enemies or intuitive HUD systems). I didn't go all out on the demo scene as my player is just a capsule moved by a FPC. The static health bars are achieved with quad objects and can also be moved to world space. Here are the screens and it is now available in the asset store!
