Spawning object by using ray

Questions & Answers

This is the code :

var ray = CameraUI.ScreenPointToRay(Input.mousePosition);
    var hit : RaycastHit;
    if(Physics.Raycast(ray,hit)){
    //Debug.Log("Now I see a cube");
    if(hit.collider.tag == "RayEnemy" ){
    Debug.Log("I see a unit");
     if(Input.GetMouseButtonDown(0))Instantiate (particle, hit.point, transform.rotation);

The problem is that the particle instance is spawned somewhere related to the detected collider but if I move the camera I can see that in fact the particle instance is in mid air somewhere between collider and camera or around collider.

How can I spawn the particles (a lightning strike spell) right under collider position (on the ground under my unit because the collider is centered on the unit).

Try this (untested):

if(Input.GetMouseButtonDown(0)) {
    var bounds = hit.collider.bounds;
    var v3 = bounds.center;
    v3.y -= bounds.extents.y;
    Instantiate (particle, v3, transform.rotation);

}
