When i click on Object, .. raycast help!

this is in C# but its an example of a door in front of you being found and the player clicking.

Ray MyRay; RayCastHit HitInfo;

 //cast from the cameras postion
 MyRay.origin = Camera.main.transform.position;
 
 //cast directly out in front of the camera
 MyRay.direction = Camera.main.transform.forward;
 
 
 physics.raycast(Myray, out HitInfo);
 
 if (HitInfo)
 {
   if(HitInfo.gameobject.tag == "Door")
   {
     if(Input.GetMouseButtonDown(0))
      { 
        someone just clicked and a door is in front of you 
      }
    }
 }

Tank you, but i explain my problem

I have a door prefab ( "Door" ) with a object in it ( "Door_1") with a door object in it..

so when i click the "Door" i want "Door_1" to start the animation "Open"..

But just the door i clicked has to start the animation, you unsterand?

thanks
