Creating A wall Jump

Hey Guys, I'm trying to create a wall jump script that I have been stuck on for a while. I'm pretty new to using unityscript and coding in general and I'm trying to figure it out. Currently I am using the platformer controller that comes with unity script but I am trying to add this script to my object so he can wall jump. Thanks for your help.

 private var canWallJumpDir : Vector3 = Vector3.zero;
 private var moveDirection : Vector3 = Vector3.zero;
 var speed : float = 26.0;
 var jumpSpeed : float = 500.0;
 var gravity : float = 20.0;
 
 
     
     function Update () {        
         
         var fwd = transform.TransformDirection (Vector3.forward);
         var controller : CharacterController = GetComponent(CharacterController);
        
        
            if (controller.isGrounded == false){
                 // canWallJumpTime = Time.time;
                 moveDirection = Vector3(Input.GetAxis("Vertical"),0);
                 moveDirection = transform.TransformDirection(moveDirection);
                 moveDirection *= speed;
                 if(Physics.Raycast(transform.position, fwd, 1 && Input.GetButton("Jump"))) {
                     print("There is something in front of the object!");
                     moveDirection.y = jumpSpeed;
                
             }
         else{
             print ("We are grounded");
             }
         }
     // apply gravity
     moveDirection.y -= gravity * Time.deltaTime;
     
     // Move The controller
     controller.Move(moveDirection * Time.deltaTime);
   }
     
 @script RequireComponent (CharacterMotor)
