I need to add a reload animation whenever I pick up ammo boxes. Like putting a mag in a gun whenever I walk into one of them what can I do to this code to start that animation?

var Effect : Transform;
var TheDamage = 50;
var BulletSound : AudioClip;
var Ammo : int;
function Start ()
{
Ammo = 30;
}

function Update () 
{
 
    var hit : RaycastHit;
    var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 0));
 
    if (Input.GetMouseButtonDown(0))
    {
       {
       if (Physics.Raycast (ray, hit, 300))
       if (Ammo> 0)
         {
          Ammo --;
          BroadcastMessage("Recoil");
          audio.PlayOneShot(BulletSound);
          var particleClone = Instantiate(Effect, hit.point, Quaternion.LookRotation(hit.normal));
          Destroy(particleClone.gameObject, 2);
          hit.transform.SendMessage("ApplyDamage", TheDamage, SendMessageOptions.DontRequireReceiver);
         }
       }
 
 
    }
 
}
 
function OnGUI()
{
    if(Ammo > 0)
    {
    GUI.Label(Rect(100,0,100,100),Ammo.ToString());
    }
 
    if(Ammo == 0)
    {
    GUI.Label(Rect(100,0,100,100),"No Ammo");
    }
 
 
}

Also my Player atributes code (for the boxes)

function OnTriggerEnter(other : Collider)
{
	if(other.tag == "ammo")
	{
		shootObject.GetComponent(Raycastshooting).Ammo += 30;
		Destroy(other.gameObject);
	}
}

If you want an animation to play when you collide with (pick up) an ammo box, you just need to trigger the animation during that part of your script.

    function OnTriggerEnter(other : Collider)
    {
        if(other.tag == "ammo")
        {
        shootObject.GetComponent(Raycastshooting).Ammo += 30;
        Destroy(other.gameObject);

        //Play reload animation
        animation.Play("reload");
        }
    }
