Hi, everyone

Is there a script that when I click a certain object, the object should become new target of camera each time i click.

i am using this code for camera.

//WASD to orbit, left Ctrl/Alt to zoom
using UnityEngine;
using System.Collections;

[AddComponentMenu("Camera-Control/Keyboard Orbit")]

public class Guikeys : MonoBehaviour {
    public Transform target;
    public float distance = 20.0f;
    public float zoomSpd = 2.0f;

    public float xSpeed = 240.0f;
    public float ySpeed = 123.0f;

    public int yMinLimit = -723;
    public int yMaxLimit = 877;

    private float x = 0.0f;
    private float y = 0.0f;

    private float GUIHorizontal = 0;
    private float GUIVertical = 0;

    public Texture uptexture;
    public Texture lefttexture;
    public Texture righttexture;
    public Texture downtexture;

    public void Start () {
        Vector3 angles = transform.eulerAngles;
        x = angles.y;
        y = angles.x;

        // Make the rigid body not change rotation
        if (rigidbody)
            rigidbody.freezeRotation = true;
    }



void OnGUI()
{
    if(Event.current.type == EventType.Repaint)
    {
        GUIHorizontal = 0;
        GUIVertical = 0;
    }
    GUILayout.BeginVertical();
    if(GUI.RepeatButton(new Rect(70,600,30,30), uptexture))
    {
        GUIVertical = 1;
    }
    GUILayout.BeginHorizontal();
    if(GUI.RepeatButton(new Rect(35, 630, 30, 30), lefttexture))
    {
        GUIHorizontal = -1;
    }
    if(GUI.RepeatButton(new Rect(103, 630, 30, 30), righttexture))
    {
        GUIHorizontal = 1;
    }
    GUILayout.EndHorizontal();
    if(GUI.RepeatButton(new Rect(70, 658, 30, 30), downtexture))
    {
        GUIVertical = -1;
    }
    GUILayout.EndVertical();
}


    public void LateUpdate () {
        if (target) {


         x -= Input.GetAxis("Horizontal") * xSpeed * 0.02f;
         y += Input.GetAxis("Vertical") * ySpeed * 0.02f;


            x -= GUIHorizontal * xSpeed * 0.02f;
            y += GUIVertical * ySpeed * 0.02f;

            y = ClampAngle(y, yMinLimit, yMaxLimit);

        distance -= Input.GetAxis("Fire1") *zoomSpd* 0.02f;
            distance += Input.GetAxis("Fire2") *zoomSpd* 0.02f;

            Quaternion rotation = Quaternion.Euler(y, x, 0.0f);
            Vector3 position = rotation * new Vector3(0.0f, 0.0f, -distance) + target.position;

            transform.rotation = rotation;
            transform.position = position;
        }
    }

    public static float ClampAngle (float angle, float min, float max) {
        if (angle < -360.0f)
            angle += 360.0f;
        if (angle > 360.0f)
            angle -= 360.0f;
        return Mathf.Clamp (angle, min, max);


    }
}

Thanx
