Right click and destroy game object.

This script should work fine (if attached to the object). The object must be a GUIText, GUITexture or have a collider for OnMouseOver to work. Additionally, if the collider doesn't match the model shape (as when you have a CharacterController and a humanoid model) you may click on parts of the model without actually hitting its collider - or vice versa, destroying the object when clicking near to the model.
The worst thing about this script is that it must be attached to all destructible objects. If you want a single script to do this job, attach this one to the camera:

function Update(){
  if (Input.GetMouseButtonDown(1)){
    var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    var hit: RaycastHit;
    if (Physics.Raycast(ray, hit)){
      Destroy(hit.transform.gameObject);
    }
  }
}

Yeah, you had if (Input.GetMouseButtonDown(1)) that will return if you right click.

For left click, you want if(Input.GetMouseButtonDown(0))

Hope this helps!!!!!

Hi,

You can use this code in the objects update method:

 public class DestroyPlayAudio : MonoBehaviour
     {
         public AudioSource audioSource;
         public AudioClip clip;
         public float volume=0.5f;
     
         void Update()
         {
              if (Input.GetButtonDown ("1")) 
             {
                 Raycast ray=Camera.main.ScreenPointToRay(Input.mousePosition);
                 Raycasthit hit;
                 if (Physics.Raycast(ray, out hit))
                 {
                     Destroy(hit.collider.gameObject);
                     audioSource.PlayOneShot(clip, volume);
                 }  
             }
         }
     }

Insert your audiofile in the variable slot in the Monobehaviour.
