Uh, I haven't used the latest versions for away3d, but there was always a camera.lookAt() function that you could just pass any other object in the scene to. If you don't want the camera to pan or tilt as the character moves left and right, why not just create a Point3D somewhere far off in the distance behind the character, and have the camera lookAt() that to start out with, then just move the camera along whatever axis the character is moving on (z, presumably) as the character moves...
