RayCasting Mouse
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 this 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);
Exactly what i wanted, thanks, Would be good to move to answer

Have you tried:
Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition);
RaycastHit hit;
if (Physics.Raycast(ray, out hit, 100))
{
//Do something 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 this 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 hit, 100f)) {
}
