Question by Bohemond · Aug 22, 2017 at 10:00 AM · gameobjectscriptingbasicsonmousedown

OnMouseDown on another object

Hi ! ^^

I don't know how to do something with my script (change a value, creat a GameObject,...) when the mouse click on an object which not contains the script. How can I do this ?

I know the command OnMouseDown and Public GameObject and I think the solution will use this 2 commands

Here is my code:

     using System.Collections;
     using System.Collections.Generic;
     using UnityEngine;
     using UnityEngine.UI;
     
     public class Player : MonoBehaviour {
     
         public float life;
 
         void Start ()
 
        {
                life = 3;
        }
 
         void OnMouseDown ()
     
     // Here my code is uncomplete. I want the value ''life'' gains +1 when I click on a GameObject named ''food''//
     
         {
             life = life + 1;
         }
     }

For the moment, the value ''life'' gains +1 when I click on the Player (which contains the script) but I want the value changes when I click on another GameObject named ''food''. Can you explain me how I do this ?

@akillingbeck, to get reference of an object, I use public gameObject

Can you post code you have now? There's a couple of solutions for this. But it depends what you want. Do you just want to get a reference to the object you clicked on?

The easiest way to do this is to create a prefab of the "Food" and attach a small script to it and a collider:

      public class Food : MonoBehaviour {
      
          Player playerScript; 
  
          void Start ()
  
         {
                playerScript = GameObject.Find("Player").getComponent<Player>();
         }
  
          void OnMouseDown ()    
          {
              playerScript.life += 1;
              Destroy(gameObject);
          }
      }
