How to destroy a gameObject when hit by Raycast?

Question

After the explosion has been instantiated, I would like to destroy the gameObject I hit. Heres my code:

 > if(Input.GetKeyUp(KeyCode.Mouse0)) {
 >             Debug.Log("Shot a bullet");
 >             var fwd = transform.TransformDirection
 > (Vector3.forward);
 >             var hit :RaycastHit;
 >             
 >             if (Physics.Raycast (transform.position, fwd, hit, 60)) {
 >                 Debug.Log ("Target Hit");
 >                 Instantiate(bulletCheck, hit.point, transform.rotation);
 >                 Instantiate(explosion, hit.point, transform.rotation);
 >                           //Here I want to destroy the gameObject I hit.
 >             }
 >             
 >         }

The RaycastHit structure contains the hit object's transform, which can be used to access the gameObject property:

 if (Physics.Raycast (transform.position, fwd, hit, 60)) {
     ...
     Destroy(hit.transform.gameObject); // destroy the object hit
 }

Thanks so much!

with help from another form i dont remember. I used this to destroy my object:

if (Input.GetButtonDown ("Fire1")) {

// Construct a ray from the current mouse coordinates var ray : Ray = Camera.main.ScreenPointToRay Input.mousePosition);

}

if (Physics.Raycast(ray, hit) && (hit.transform.gameObject == transform.gameObject)) {

Destroy(hit.transform.gameObject); Instantiate(smoke, transform.position, Quaternion.identity); }

Es increible que no haya un curso de unity y que nadie te explique bien como se usa cada cosa.

Try:

 Destroy(hit.collider.gameObject);

1 - Have a gameobject in the scene named "Camera" with a cameracomponent on it.

2 - Make sure there is a collider on the object you try to hit.

http://docs.unity3d.com/412/Documentation/ScriptReference/Physics.Raycast.html - at the bottom of the document.

(C#)

 private Transform cameraTransform;
 private Camera cam;

 void Start(){
     cameraTransform = GameObject.Find("Camera").transform;
     cam = cameraTransform.camera;
 }

 void Update(){

     if (Input.GetMouseButtonDown(0)) {
     
         Ray ray = cam.ScreenPointToRay(Input.mousePosition);
         RaycastHit hit;

         if (Physics.Raycast(ray, out hit, 10000)){
             Debug.DrawLine(ray.origin, hit.point);
             Debug.Log("Clicked on " + hit.transform.gameObject.name); 
             Destroy(hit.transform.gameObject);
         }        
     }
 }

if you want to make a game like an ant smash in 3d then this one is helping you

 Camera mainCam;
  // target layer set in inspector [ specific object with this layer ]
 public LayerMask layer;

 private void Awake () {
     mainCam = Camera.main;
 }
 private void Update () {
     // Calculate the distance
     Ray ray = mainCam.ScreenPointToRay (Input.mousePosition);
     Plane plane = new Plane (Vector3.up, Vector3.forward);
     float rayDistance;

     if(plane.Raycast(ray, out rayDistance)) {
         Vector3 point = ray.GetPoint (rayDistance);
         // Draw a line btw camera to end point
         Debug.DrawLine (ray.origin, point, Color.red);      
     }
     RaycastHit hit;
     if(Physics.Raycast (ray, out hit, rayDistance, layer, QueryTriggerInteraction.Collide)) {
         if(hit.collider != null) {
             Destroy (hit.collider.gameObject);
             Debug.Log (hit.collider.name);
         }   
     }
