The actorlist is a double linked ring list containing actornodes. The purpose of actors is to provide positional and movement information in space without information about visual appearance or collision behavior. The matrices of the actors can be linked against l3dnodes in order to display objects on the screen.
Each actor has a name and can be found by using the name. Actors with the same name are grouped in a ring list that can be traversed.
