Collision triggered multiple time when jumping

Unity Engine
1

Hi, I have a problem when I collide with an enemy in my game. If I jump and then hit the enemy, I lose all of my life instantly. Here is the code causing the problem :

function OnControllerColliderHit(hit:ControllerColliderHit){
    if(hit.collider.tag == "ennemi"){
        PerdreVie();
        vie--;
        print(vie);
        if(vie == 0){
            this.enabled = false;
            yield WaitForSeconds(3);
            Application.LoadLevel(Application.loadedLevel);
        }else{
            yield WaitForSeconds(2);
        }
    }
}

what does PerdreVie();

It just remove a life in the canvas :

function PerdreVie(){
    Debug.Log("perdre vie");
    var feuilleActuelle = "feuille_"+vie;
    var gererAnimation = GameObject.Find(feuilleActuelle).GetComponent(Animator);
    Debug.Log(GameObject.Find(feuilleActuelle));
    //GameObject.Find(feuilleActuelle).SetActive(false);
    //GameObject.Find(feuilleActuelle).transform.localScale = Vector3(0,0,0);
    Debug.Log(feuilleActuelle);
   
    gererAnimation.SetBool("perdre_vie",true);
    gererAnimation.SetBool("gagner_vie",false);
    //var infostat = feuilleAnim_1.GetCurrentAnimatorStateInfo;
    //Debug.Log(infostat);
   
}

Frames move super fast"Light Speed" so when you have a object collide it last 4-5 frames. thats why its registering its triggering multiple times

Isn’t there a way to prevent this ?

Sorry, for being late. You could make a timer so then it would slow it down.

if hit.colder thing you have

Timer = .2f; 

Timer -= Time.DeltaTime * speed of whatever; 

if (Timer = 0){
do all your code

}

A timer is the way to do this but not sure this is the most efficient way.
