Collision triggered multiple time when jumping

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 :

Code (JavaScript):

1. function OnControllerColliderHit(hit:ControllerColliderHit){
2.     if(hit.collider.tag == "ennemi"){
3.         PerdreVie();
4.         vie--;
5.         print(vie);
6.         if(vie == 0){
7.             this.enabled = false;
8.             yield WaitForSeconds(3);
9.             Application.LoadLevel(Application.loadedLevel);
10.         }else{
11.             yield WaitForSeconds(2);
12.         }
13.     }
14. }

 

what does PerdreVie();

 

It just remove a life in the canvas :

Code (JavaScript):

1. function PerdreVie(){
2.     Debug.Log("perdre vie");
3.     var feuilleActuelle = "feuille_"+vie;
4.     var gererAnimation = GameObject.Find(feuilleActuelle).GetComponent(Animator);
5.     Debug.Log(GameObject.Find(feuilleActuelle));
6.     //GameObject.Find(feuilleActuelle).SetActive(false);
7.     //GameObject.Find(feuilleActuelle).transform.localScale = Vector3(0,0,0);
8.     Debug.Log(feuilleActuelle);
9.    
10.     gererAnimation.SetBool("perdre_vie",true);
11.     gererAnimation.SetBool("gagner_vie",false);
12.     //var infostat = feuilleAnim_1.GetCurrentAnimatorStateInfo;
13.     //Debug.Log(infostat);
14.    
15. }

 

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.

Code (csharp):

1.  
2. if hit.colder thing you have
3.  
4. Timer = .2f;
5.  
6. Timer -= Time.DeltaTime * speed of whatever;
7.  
8. if (Timer = 0){
9. do all your code
10.  
11. }
12.  

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