Funny error. collision just hit 12 times

Hey, Guys!

Well... that's odd, but I'll try to explain. I have a robot with a box collider in $$anonymous$$s sword. And I have a Script attached to my player that checks the collision with the enemy's sword, And so far, it's barely ok. Because I have 2 issues.

First. When the robot's sword $$anonymous$$ts the player, the collision checks twice or more, but I'm gonna let this way, maybe I just expand the player health, though.

Second. The robot saw me, run at me and start to attack. every $$anonymous$$t will collide and drop my health, but after the 12nd $$anonymous$$t, the collision doesn't works anymore. He's just swinging $$anonymous$$s sword, and the collisions backs to work when I move the player.

Very odd, huh? Is that happened before? Well, I'm posting my scripting so far.

The Enemy AI script:

 var waypoint : Transform[];        // The amount of Waypoint you want
 
             var patrolSpeed : float = 3;       // The walking speed between Waypoints
 
             var loop : boolean = true;       // Do you want to keep repeating the Waypoints
 
             var player : Transform;          // Referance to the Player
 
             var dampingLook = 6.0;          // How slowly to turn
 
             var pauseDuration : float = 0;   // How long to pause at a Waypoint
 
             var attackRange = 10;          // Range to start the attack
 
             var attackSpeed = 5.0;          // Speed to attack
 
             var attackLook = 10.0;          // How fast to turn when attacking

                    var rotation = Quaternion.LookRotation(target - transform.position);

             function attack(){

             }
 
             else {
 
             animation.Stop("attack");
 
             }
 
                
 
             // Rotate to face the Player
 
             var lookPos = player.position - transform.position;
 
                 lookPos.y = 0;
 
                 var rotation = Quaternion.LookRotation(lookPos);
 
                 transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * attackLook);
 
 
 
             // Move towards the Player
 
                 var target : Vector3 = player.position;
 
                 var moveDirection : Vector3 = target - transform.position;
 
 
 
                 moveDirection.y = 0; // Stop the character running up off the floor to match the Players Y axis
 
                 moveDirection.y -= gravity; // Add gravity so the he always stays on the ground
 
                 character.Move(moveDirection.normalized * attackSpeed * Time.deltaTime);
 
                 animation.Play("run");
 
             }
 
             
 
             
 

 And that's is the script that checks the collision the player with the sword

 var PlayerLife = 3;
 var player : Transform;
 private var m_isHit : boolean = false;
 
 
 //function OnControllerColliderHit($$anonymous$$t: ControllerColliderHit){
 
 function OnTriggerExit (other : Collider) {
 if(other.gameObject.tag == "attackPoint"){
 PlayerLife -= 1;
  
 } 
 
 }
 //}
 
 
 
 function Update () {
 
 print ("Health :" +PlayerLife);
 }
