EDSS - Eight Directional Sprite System (code name: Retro FPS Avatars) is a system that allows you to display 2-dimensional sprites in the 3D world in the way used in some 3D oldschool FPS games.
SHORT DESCRIPTION
Each EDSS actor consists of two separate objects. The main object is responsible for the position and orientation of the actor in the scene. The second, subordinate object is responsible for the graphical representation of the actor.
The Actor Billboard component deals with determining which image from a given animation should be displayed by the Sprite Renderer component and additionally it deals with setting the sprite so that it always faces the camera. Just before rendering by the current camera, the Actor Billboard component will use the current actor vector to determine the image to be displayed.
