I uploaded the first of what I hope/plan to be a series of video Unity Tutorials.
In this video, we implement basic player character navigation using a CharacterController Component, its SimpleMove() function, and a simple Camera for first or third person games.
The Unity package for this tutorial can be downloaded from http://www.brenlynne.com/unitytutorials/UnityTutorial1-BasicCharacterNavigation.unitypackage
