Problem with PlayerHealth and renderer

Questions & Answers
1

I have built a playerHealth script and I did when the player loses life, meshrenderer to blink every 1 second but when he receives damage do more than once because when he feels damage and boolean when is activated, I have made is activated and make multiple times instead of a. How can I do to flash as I want? See the code:

var curHealth : int = 70;
var maxHealth : int = 100;
var deadMode = false;
 
var curProtect = false;
static var damageCost = 10;
 
function Update () {
    if(curHealth >= maxHealth) {
       curHealth = maxHealth;
    }
 
    if(curHealth <= 0) {
       curHealth = 0;
       deadMode = true;
    }
 
    if(curHealth > 0) {
       deadMode = false;
    } 
 
    protectedMode();
}
 
function OnTriggerEnter( other : Collider) {
    if(other.tag == "Enemy" && !curProtect) { 
       curProtect = true;
       curHealth -= damageCost;
    }
}
 
function protectedMode() {
 
    if(curProtect) {
         graphicsSkin = transform.Find("Graphics");
 
 
         graphicsSkin.renderer.enabled = false;
         yield WaitForSeconds(1);
 
         graphicsSkin.renderer.enabled = true;
         yield WaitForSeconds(1);
         graphicsSkin.renderer.enabled = false;
         yield WaitForSeconds(1);
 
         graphicsSkin.renderer.enabled = true;
         yield WaitForSeconds(1);
         graphicsSkin.renderer.enabled = false;
         yield WaitForSeconds(1);
 
         graphicsSkin.renderer.enabled = true;
         yield WaitForSeconds(1);
 
       curProtect = false;
    }

}

You can use InvokeRepeating(). You can use CancelInvoke() to turn the blinking back off:

#pragma strict

function Start() { 
	InvokeRepeating("BlinkMe",0.0,1.0);
} 

function BlinkMe() { 
	renderer.enabled = !renderer.enabled;
}

Note the last parameter to the InvokeRepeating() is the time between invokes. A smaller number will cause your character to blink faster.
