mouse clicked on object animation c#

Question

Hi, im trying to make a small part of my game where when the player click on the game object, the player will know that they have clicked it.

E.g When I left mouse button click on the object, the object size increases then returns back to its original size. Allowing the player to know that they have clicked that object.

Create a new "Mouse" C# script and paste it:

 using UnityEngine;
 using System.Collections;
 
 class Mouse : MonoBehaviour {
     public static bool isLeftButton = false;
     public static bool isRightButton = false;
     public static bool isMiddleButton = false;
 
     public static bool isLeftButtonDown = false;
     public static bool isRightButtonDown = false;
     public static bool isMiddleButtonDown = false;
 
     public static GameObject onLeftButtonDown;
     public static GameObject onRightButtonDown;
     public static GameObject onMiddleButtonDown;
 
     public static GameObject onLeftButtonUp;
     public static GameObject onRightButtonUp;
     public static GameObject onMiddleButtonUp;
 
     public static GameObject onLeftButton;
     public static GameObject onRightButton;
     public static GameObject onMiddleButton;
 
     public static GameObject onEnter;
     public static GameObject onOver;
     public static GameObject onExit;
 
     public static bool isMove = false;
     public static Vector3 incrementPositionInWorld;
     public static Vector3 absolutePositionInWorld;
 
     private Ray mouseRay;
     private RaycastHit hit;
 
 
     void Update() {
         if (Camera.main) {
             isLeftButton = Input.GetMouseButton(0);
             isRightButton = Input.GetMouseButton(1);
             isMiddleButton = Input.GetMouseButton(2);
 
             isLeftButtonDown = Input.GetMouseButtonDown(0);
             isRightButtonDown = Input.GetMouseButtonDown(1);
             isMiddleButtonDown = Input.GetMouseButtonDown(2);
 
             mouseRay = Camera.main.ScreenPointToRay( new Vector3(Input.mousePosition.x, Input.mousePosition.y, 0f) );
             Physics.Raycast(mouseRay,out hit);
     
             Vector3 mousePos = Input.mousePosition;
             if (hit.collider) {
                 mousePos.z = hit.collider.gameObject.transform.position.z - Camera.main.transform.position.z;
             }else mousePos.z = -0.05f;
             mousePos = Camera.main.ScreenToWorldPoint(mousePos);
             incrementPositionInWorld = mousePos - absolutePositionInWorld;
             if ( incrementPositionInWorld.magnitude > 0f ) isMove = true;
             else isMove = false;
             absolutePositionInWorld = mousePos;
     
     
             onExit = null;
             if ( (hit.collider && onOver != hit.collider.gameObject) || !hit.collider ) onExit = onOver;
     
     
             if ( hit.collider ) {
                 if (onOver != hit.collider.gameObject) onEnter = hit.collider.gameObject;
                 else onEnter = null;
                 onOver = hit.collider.gameObject;
             }else {
                 onEnter = null;
                 onOver = null;
             }
     
     
             if ( Input.GetMouseButton(0) ) onLeftButton = onOver;
             else onLeftButton = null;
 
             if ( Input.GetMouseButton(1) ) onRightButton = onOver;
             else onRightButton = null;
 
             if ( Input.GetMouseButton(2) ) onMiddleButton = onOver;
             else onMiddleButton = null;
     
     
 
             if ( Input.GetMouseButtonDown(0) ) onLeftButtonDown = onOver;
             else onLeftButtonDown = null;
 
             if ( Input.GetMouseButtonDown(1) ) onRightButtonDown = onOver;
             else onRightButtonDown = null;
 
             if ( Input.GetMouseButtonDown(2) ) onMiddleButtonDown = onOver;
             else onMiddleButtonDown = null;
     
     
 
             if ( Input.GetMouseButtonUp(0) ) onLeftButtonUp = onOver;
             else onLeftButtonUp = null;
 
             if ( Input.GetMouseButtonUp(1) ) onRightButtonUp = onOver;
             else onRightButtonUp = null;
 
             if ( Input.GetMouseButtonUp(2) ) onMiddleButtonUp = onOver;
             else onMiddleButtonUp = null;
         }
     }
 }

Attach this script to any gameObject in scene! Now you can access it from any other C# script like this:

 using UnityEngine;
 using System.Collections;
 
 public class Player : MonoBehaviour {
     GameObject currentSelected;
     private Vector3 originScale;
     
     void Update () {
         if (Mouse.isLeftButtonDown) {
             print ("ok");
             if (Mouse.onLeftButtonDown!=null && Mouse.onLeftButtonDown.tag == "Selectable") {
                 if (currentSelected != null) currentSelected.transform.localScale = originScale;
                 currentSelected = Mouse.onLeftButtonDown;
                 originScale = currentSelected.transform.localScale;
                 currentSelected.transform.localScale *= 1.5f;
                 Debug.Log("You Select: " + currentSelected);
             }else {
                 if (currentSelected != null) currentSelected.transform.localScale = originScale;
                 currentSelected = null;
             }
         }
     }
 }
