Question by bsbimalbose · Dec 14, 2013 at 05:33 PM · 2draycastcollider

Raycast on a 2D Collider

I want to raycast from the camera to the mouse location for my @D Game to identify which Object was clicked.

     Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

     RaycastHit hit;
     if(Physics.Raycast(ray,out hit))
     {
         isHit = false;
         Destroy(GameObject.Find(hit.collider.gameObject.name));

     }


Raycasting on 2D Colliders doesn't seem to work.

For 2D Colliders you need use Physics2D and RaycastHit2D instead of Physics.

 void Update(){
         
         RaycastHit2D hit = Physics2D.Raycast(cameraPosition, mousePosition, distance (optional));
         
         if(hit != null && hit.collider != null){
             isHit = false;
             Destroy(GameObject.Find(hit.collider.gameObject.name));
         }
     }

Use it with a Vector2 mousePosition or if your game is 3D use 3D colliders instead of 2D.

To clarify:

 Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 RaycastHit2D hit = Physics2D.Raycast(ray.origin, ray.direction);

If you're using the new 2d stuff you'll need to use the Physics2D functions.
