OnMouseDown with Tags

Question

Hello all,

I want to be able to click on any gameobject, and if it is tagged with "ClickArea", an int increases. I have a script, but the click does not register:

-the gameobjects being clicked are tagged -my script is attached in scene -debug.log does not return.

While researching, I found this similar answer: http://answers.unity3d.com/questions/1028472/onmousedown-issues.html

@getyour411 , you mentioned that you thought you could take a look at this other thread. Does anyone know why this is happening?

my script:

 using UnityEngine;
 using System.Collections;
 
 public class playerpref1 : MonoBehaviour {
 
 
     public CarrotCount _carrotcount;
     public int picked;
     // Use this for initialization
     void Start ()
     {
         picked = PlayerPrefs.GetInt ("picked");
 
         StartCoroutine (c1 ());
 
     }
     
 
     void OnMouseDown () 
     {
         if (gameObject.tag == "ClickArea")
         {
             picked += 1;
             Debug.Log ("tag");
         }
 
     }
 
     IEnumerator c1 ()
     {
         yield return new WaitForSeconds (1);
         PlayerPrefs.SetInt ("picked", picked);
         Debug.Log (picked);
         PlayerPrefs.Save ();
 
         StartCoroutine (c1 ());
     }
 }

Any ideas? Once again, thanks for the help.

Since you want this script on a different GameObject to what is clicked you need to use raycasts instead of the OnMouseDown() method. Here is you code using raycast:

 using UnityEngine;
 using System.Collections;
 
 public class playerpref1 : MonoBehaviour
 {
 
     public int picked;
     // Use this for initialization
     void Start()
     {
         picked = PlayerPrefs.GetInt("picked");
 
         StartCoroutine(c1());
 
     }
 
 
     void Update()
     {
         if (Input.GetMouseButtonDown(0))
         {
             Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             RaycastHit hitInfo;
             if (Physics.Raycast(ray, out hitInfo))
             {
                 if (hitInfo.collider.gameObject.tag == "ClickArea")
                 {
                     Debug.Log("tag");
                     picked++;
                 }
             }
         }
     }
 
     IEnumerator c1()
     {
         yield return new WaitForSeconds(1);
         PlayerPrefs.SetInt("picked", picked);
         Debug.Log(picked);
         PlayerPrefs.Save();
 
         StartCoroutine(c1());
     }
 }

Is there a way to do this with 2D sprites instead of a 3D object?
