Third person animation

Hi everyone.

i have some problem with this third person animation (from the build in thirdpersonshooter.js (unity assets)) and i'm just going to list it

1. How to make the player hand look at the mouse position when pressing right click ?

After the player presses right click, the MouseOrbit will zoom in and the character animation plays readypose (_animation[readypose.name].layer = 1; and _animation.CrossFade(readypose.name);). but the character hand won't move according to the mouse position.

 function ReadyToShoot(){ //Invoked when player presses right click
     _characterState = CharacterState.Ready; //plays readypose on Update function
     
     x += Input.GetAxis("Mouse X") * 60 * 0.02;
     y -= Input.GetAxis("Mouse Y") * 60 * 0.02;
                             
     var rotation = Quaternion.Euler(y, x, 0);
     
     hand.LookAt(rotation.eulerAngles); //move if i attached hand to unskinned object, can't move if i attached to skinned / animationed transform.
     if(Input.GetButton("Fire1")){
         var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         if (Physics.Raycast (ray) && !IsMoving() && !IsJumping()){
             ApplyShooting();
         }
     }

thanks for answering
