Move character in direction of camera

Code (csharp):

1. cameraDirection = cameraPlayer.transform.forward;
2.      
3. currentMovement = new Vector3(0, currentMovement.y, Input.GetAxis("Vertical") * moveSpeed);

I'm trying so hard to find a line of code that needs to go between these 2 lines that will change the rotation of the player to the direction of the camera. To be clear I don't want the player constantly rotate to the direction of the camera, but only when I move forward does the player rotate to the direction of the camera.

I know I'm so close but I just can't find the right way to do it. Any help at all would be great!

 

Hi ,
Try this

Code (CSharp):

1. if (Input.GetAxis ("Vertical") > 0)
2.             Player.transform.forward = cameraDirection;
