RayCasting Mouse

Question

Hi everyone,

I was just wondering how you would go about RayCasting a mouse in Unity, at the moment I have it attached to the camera and would like to know if it was possible to do t$$anonymous$$s with the mouse. If it isnt could I Raycast via a Object that Follows the mosue.

Code : ray = new Ray (Camera.main.transform.position, Camera.main.transform.forward);

Have you tried:

 Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
         RaycastHit $$anonymous$$t;
 
         if (Physics.Raycast(ray, out $$anonymous$$t, 100))
         {
             //Do somet$$anonymous$$ng here if the mouse is over a object?
         }

Is that what you wanted to do?

If you're working for Editor only then above answer will work . If you're creating game of iOS/Android then you will need t$$anonymous$$s in the end to cast ray when screen touched .

                         #if UNITY_EDITOR
                         ray = Camera.main.ScreenPointToRay (Input.mousePosition);
                         #elif (UNITY_ANDROID || UNITY_IPHONE)
                          ray = Camera.main.ScreenPointToRay (Input.GetTouch (0).position);
                         #endif
                         if (Physics.Raycast (ray, out $$anonymous$$t, 100f)) {
                             }
