Walking through m2h tutorial 2b
All done just like at those example.
But both players objects (instantiated copyes of player prefab) is under control by both players.
Is this situation common for newbies? How can I solve it?
(Player prefab is FirstPersonController from Standart Assets)
Now both objects controls by server, client do not control anyone. 
Objects instantiates in OnConnectedToServer and OnServerInitialized functions, like in example.
var cam:Transform;
function Start () {
}
function Update () {
if(networkView.isMine) {
transform.Translate(Input.GetAxis("Horizontal")/10,0,Input.GetAxis("Vertical")/10);
cam.transform.Rotate(-Input.GetAxis("Mouse Y")*10,0,0);
transform.Rotate(0,Input.GetAxis("Mouse X")*10,0);
}
}
