Question by Rybo5000 · Jul 21, 2013 at 07:55 AM · c#inputmouse

Get GameObject That Was Last Clicked?

I know how to check if a gameobject was clicked using RayCast but what is the best way to check the last object that was clicked?

I was thinking something like a for loop that goes through every object and does a RayCast check but that seems like it'd take too much memory for something so simple.

(C# preferably please)

Simply use a variable named something like "lastClicked". The way I have the raycast here isn't how people usually do it. The way I have it, only updates the ray on mouse click, instead of every frame.

 using UnityEngine;
 using System.Collections;
  
 public class Example : MonoBehaviour
 {
     GameObject lastClicked;
     Ray ray;
     RaycastHit rayHit;
  
     void Update()
     {
         if(Input.GetMouseButtonDown (0))
         {
             ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             if(Physics.Raycast(ray, out rayHit))
             {
                 lastClicked = rayHit.collider.gameObject;
                 if(lastClicked != null)
                     print(lastClicked.name);
             }
         }
     }
 }

in unity2D, or 2d games, this will work as well? or do you suggest a better way?

Have it SendMessage to a single ClickHandler script, pass it the unique name or some other unique identifier, or just a reference to itself.
