Attack on mouse click

Hi guys, I have a character that is moved by mouse clicks, Im having some problems now that I want to make the character to attack a turret when someone clicks on the object. So I need the character to move to the object, hit the object and play an attack animation while hitting.

This is my movement script:

 //variaveis
 var vel : int;
 vel = 0;
 var Animacao : Animation;
 
 //Clipes de animação
 var clipes:AnimationClip[];
 
 //Guarda se ja foi clicado
 private var clicado:boolean = false;
 private var seta : GameObject;
 var detectCollisions : boolean;
 
 function Start(){
 seta=GameObject.CreatePrimitive(PrimitiveType.Plane);
 seta.transform.position = Vector3(0, 0, 0);
 }
 
 function Update() {
 //se clicou com botão esq
 if(Input.GetKeyDown(KeyCode.Mouse1))
 
 {
 //Cria um plano com a posição da personagem
 var playerPlane = new Plane(Vector3.up, transform.position);
 
 //Desenha um ponto entre o personagem e o local clicado
 var ray = Camera.main.ScreenPointToRay (Input.mousePosition);
 var hitdist = 0.0;
 vel = 10;
 
 //Seta que foi clicado
 clicado = true;
 
 //Verifica se pode mover-se e desenha o caminho
 if (playerPlane.Raycast (ray, hitdist)) {
 
 //cria variavel depois de criado o caminho
 var targetPoint = ray.GetPoint(hitdist);
 
 //guarda a rotação
 targetPosition = ray.GetPoint(hitdist);
 
 var targetRotation = Quaternion.LookRotation(targetPoint - transform.position);
 seta.transform.position = Vector3(targetPosition.x,targetPosition.y,targetPosition.z );
 
 //Ajusta rotação da personagem
 transform.rotation = targetRotation;
 }
 
 rigidbody.isKinematic = false;
 rigidbody.detectCollisions = true;
 
 }
 
 //Caso a personagem não esteja no ponto clicado ela anda até lá
 if((transform.position - seta.transform.position).magnitude > 2){
 transform.Translate(Vector3.forward * ( Time.deltaTime * vel));
 
 //animação dele a andar
 Animacao.clip = clipes[1];
 Animacao.Play();
 }
 else
 {
 //animação dele parado
 Animacao.clip = clipes[0];
 Animacao.Play();
 }
 }

I think this script might help with something (Untested):

 #pragma strict
 
 var currentWeaponRange : float = 10.0;
 var locationToMoveTo : Vector3;
 var dir : Vector3;
 
 //Transforms
 
 var movePoint : Transform;
 var currentTarget : Transform = null;
 private var currentMovePoint : Transform;
 
 var FireDmg : int = 10;
 
 var hit : RaycastHit;
 var ray : Ray;
 
 var enemyScript : DamageReceiver = null;
 
 function Update () 
 {
     //Mouse Location awarenesss. When Mouse-Left is pressed, then...
     if(Input.GetMouseButtonDown(1)) 
     {
  ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         //Casts a ray, stores the location and object it transected in Hit
         if(Physics.Raycast(ray,hit,1000))   
         {
             //If it hits an Enemy-
             if(hit.transform.tag == "Test")    
             {
              print("Encontrou Test");
                 currentTarget = hit.transform;
                 enemyScript = hit.transform.GetComponent(DamageReceiver);
                 Instantiate(movePoint, Vector3(hit.point.x, hit.point.y + 1, hit.point.z), transform.rotation);
                 if(Vector3.Distance(transform.position, hit.transform.position) <= currentWeaponRange)  
                 {
                     //Fire the Bullet
                     attack();
                     enemyScript.ApplyDamage(FireDmg);
                     print("Enemy currently is " + enemyScript.currEnergy + "/" + enemyScript.MaxEnergy);
                     currentTarget = hit.transform;
                 }
             }
             //If it hits a Turret-
             if(hit.transform.tag == "Harvestable")  
             {
 
             }
         }
     }
 }
 
 function attack()   
 {
 
 }
