Reset Position Within CameraMove Script?

Hi everyone :)

I'm using the CameraMove Script in an Android game, and I'm trying to script a button to reset the camera position to the original once pressed. Nothing is working, so is there any way I can do this within the CameraMove script?

Here's what I've got:

using UnityEngine;

using System.Collections;

public class CameraMove : MonoBehaviour {

 public Transform target;
 
 public float distance= 1.5f;
 
 public int cameraSpeed= 5;
 
 
 
 public float xSpeed= 175.0f;
 
 public float ySpeed= 75.0f;
 
 public float pinchSpeed;
 
 private float lastDist = 0;
 
 private float curDist = 0;
 
 
 
 public int yMinLimit= 10; //Lowest vertical angle in respect with the target.
 
 public int yMaxLimit= 80;
 
 
 
 public float minDistance= .5f; //Min distance of the camera from the target
 
 public float maxDistance= 1.5f;
 
 
 
 private float x= 0.0f;
 
 private float y= 0.0f;
 
 private Touch touch;
 
 
 
 void  Start (){
     
     Vector3 angles= transform.eulerAngles;
     
     x = angles.y;
     
     y = angles.x;
     
     
     
     // Make the rigid body not change rotation
     
     if (GetComponent<Rigidbody>())
         
         GetComponent<Rigidbody>().freezeRotation = true;
     
 }
 
 
 
 void  Update (){
     
     if (target && GetComponent<Camera>()) {
         
         
         
         //Zooming with mouse
         
         distance += Input.GetAxis("Mouse ScrollWheel")*distance;
         
         distance = Mathf.Clamp(distance, minDistance, maxDistance);
         
         
         
         
         
         if (Input.touchCount == 1 && Input.GetTouch(0).phase == TouchPhase.Moved) 
             
         {
             
             //One finger touch does orbit
             
             touch = Input.GetTouch(0);
             
             x += touch.deltaPosition.x * xSpeed * 0.02f;
             
             y -= touch.deltaPosition.y * ySpeed * 0.02f;
             
         }
         
         if (Input.touchCount > 1 && (Input.GetTouch(0).phase == TouchPhase.Moved || Input.GetTouch(1).phase == TouchPhase.Moved)) 
             
         {
             
             //Two finger touch does pinch to zoom
             
             var touch1 = Input.GetTouch(0);
             
             var touch2 = Input.GetTouch(1);
             
             curDist = Vector2.Distance(touch1.position, touch2.position);
             
             if(curDist > lastDist)
                 
             {
                 
                 distance += Vector2.Distance(touch1.deltaPosition, touch2.deltaPosition)*pinchSpeed/10;
                 
             }else{
                 
                 distance -= Vector2.Distance(touch1.deltaPosition, touch2.deltaPosition)*pinchSpeed/10;
                 
             }
             
             
             
             lastDist = curDist;
             
         }
         
         //Detect mouse drag;
         
         if(Input.GetMouseButton(0))   {
             
             
             
             x += Input.GetAxis("Mouse X") * xSpeed * 0.02f;
             
             y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;       
             
         }
         
         y = ClampAngle(y, yMinLimit, yMaxLimit);
         
         
         
         Quaternion rotation= Quaternion.Euler(y, x, 0);
         
         Vector3 vTemp = new Vector3(0.0f, 0.0f, -distance);
         
         Vector3 position= rotation * vTemp + target.position;
         
         
         
         transform.position = Vector3.Lerp (transform.position, position, cameraSpeed*Time.deltaTime);
         
         transform.rotation = rotation;      
         
     }
     
 }
 
 
 
 static float  ClampAngle ( float angle ,   float min ,   float max  ){
     
     if (angle < -360)
         
         angle += 360;
     
     if (angle > 360)
         
         angle -= 360;
     
     return Mathf.Clamp (angle, min, max);
     
 }
 
 
 

}

Thanks for the help!
