yes Sr.
in fact … use 2 more invisible collide … to protect enemy. … like a trigger and not.
but not working yet.
please help

My initial thought is that maybe your obstacles are on a different layer, but you want to include that layer when you do your targeting raycast.

ok … i madea new leyer, and anemies, and walls , go on sameleyer … some times working, and some times not.
i will try more with anothers collides …

The code is relevant, even if it is very simple. Like that we get a far better idea and you can get better help…

thanks.

    var EffectsObject1: GameObject;
    var emitter : ParticleEmitter;
    var TheDamage = 100;

function Update () {

    var hit : RaycastHit ;
    var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 0));

    if (Input.GetMouseButtonDown(0))
    {
        GetComponent.<AudioSource>().Play();// shoot sound       
        emitter.GetComponent(ParticleEmitter).emit = true; //hit wall particles sys
       
        if (Physics.Raycast (ray,hit,100))   
        {   
            // small particles on hit.point
            var particleClone = Instantiate (EffectsObject1, hit.point, Quaternion.LookRotation(hit.normal));
            Destroy(particleClone.gameObject, 1);
           
            hit.transform.SendMessage("ApplyDamage", TheDamage, SendMessageOptions.DontRequireReceiver);
            Debug.Log (hit.collider.name);               
        }
    }
            else
        {
        emitter.GetComponent(ParticleEmitter).emit = false;
        }   
}

You’ll have to show your latest code for that. The video shows the problem, but - so far as I can tell - it doesn’t give the cause.

i thinks i solve it …
there is a script to doble thehit damage… and now i cancel.
thanks a lot.
