Lives bring down too fast

Question

I've written a script in order to lower a life for every collision with a trigger but when the player enters to a trigger the lives bring down extremely fast.

The scrip that i`ve written is that:

 var Vida = 3;
 
 function OnTriggerEnter2D (collision : Collider2D)
 {
 if(collision.transform.name == ("Finish"))
 {
 Vida -= 1; 
 }

Which is the mistake?

PD: I also want to lower a life when colliding with an specific tag, not a name, but I don't know what I have to write...

Thank You

Hi, it lowering super fast because it's executed every frame it's touching. There had been tens of similar cases, please try google searching before asking: http://answers.unity3d.com/questions/633254/how-to-call-ontriggerenter-once.html

And to check tag, create a new tag in tags list first, and in code it's something like this.

 if(collision.tag == "Finish"){
     //code
 }
