Actually what i want is , on clicking over Gameobject it should be stored in a variable for accessing , but if i click some other Gameobject then i should again stored in the same object(i m doing this because i have 24 Gameobjects in a single scene and all of them need to perform action on mouse click).

Supposing you are working with 3D objects

  1. Add an EventSystem in your scene (GameObject > UI > EventSystem)

  2. Attach a Physics Raycaster to the event system

  3. Create an empty with the following ClickTargetsManager script:

    using UnityEngine;

    public class ClickTargetsManager : MonoBehaviour
    {
    public GameObject CurrentTarget;

    private void Start()
{
    ClickTarget[] targets = FindObjectsOfType<ClickTarget>();
    for ( int i = 0 ; i < targets.Length ; i++ )
    {
        targets*.OnClicked += OnTargetClicked;*

}
}

private void OnTargetClicked( ClickTarget target )
{
CurrentTarget = target.gameObject;
}
}
4. Attach the following ClickTarget script to the objects that must be clicked. Don’t forget to add a Collider to each of them before
using UnityEngine;
using UnityEngine.EventSystems;

[RequireComponent(typeof(Collider))]
public class ClickTarget : MonoBehaviour, IPointerClickHandler
{
public System.Action OnClicked;

public void OnPointerClick( PointerEventData eventData )
{
if ( OnClicked != null )
OnClicked.Invoke( this );
}
}
