Unity3d the transform of the camera through the joystick output direction

To solve the problem is: the direction of the camera is not fixed, when the rocker forward (0,1) push, the protagonist to the camera orientation (ignoring the y direction) to go, when the rocker to the right (1,0) push, the protagonist towards the right direction of the camera
