OnTriggerEnter2D Detect Trigger Forever

[srfrankie]

**Hi! my trouble it’s this…
When the Object n°1 enter in the Object n°2 (this another with the script with OnTriggerEnter2D function)
it should discount points of life, but the life of the enemy (object n°2) decrease life’s continously
all object have: Rigidbody 2d’s , Colliders 2d’s and all active “Trigger” why i need.

object N°1 ----> Rayo (Rain / weapon)

object n°2 .-----> Enemigo (Enemy/Prefab)**

Enemy C# code

using UnityEngine;
using System.Collections;

public class EnemigoSalud : MonoBehaviour {

	public int vidaMaxima;
	public int vidaActual;
	public int fuerza;
	bool tocado;
	void Start () {
		vidaMaxima=100;
		vidaActual=vidaMaxima;
	}
	
	void Update () {
		if (tocado){
			vidaActual-=fuerza;
		}
	}
	void OnTriggerEnter2D (Collider2D Other){
		if (Other.CompareTag("Rayo")){
			tocado=true;
		}
	}
	void OnTriggerExit2D (Collider2D Other){
		tocado=false;
	}
}

Rain C# code

using UnityEngine;
using System.Collections;

public class Rayo : MonoBehaviour {

	void Update (){
		if (Input.GetMouseButtonUp(0))
			Destroy(gameObject);
	}
}

Maybe add a line after line 17:

tocado = false;

So you have something like this:

void Update () {
         if (tocado){
             vidaActual-=fuerza;
             tocado = false; // New line.
         }
     }

That way you only lose one life when the trigger happens. Before you were losing on life on each frame Update().
