Update Just Once

Question

I can't figure out this, I know it's been answered around a lot, but trying to figure out if an object is alive or not (exists in the scene or not) in order to activate another object if so, I did this. Obviously it works, the only problem is it keeps working :)

 function Update () {
    if (GameObject.Find (ObjectiveName) != null) {
            
            Debug.Log("STILL HERE");    
          
          } else {
             Debug.Log("DEAD");
             messageObject.gameObject.SetActive(true);
             messageText.text = myString;
          }
 }

What you could do is add a boolean to check for as well to make sure that it is only done once. Here is how I might do it:

 private var doOnce:boolean = true; 
 function Update () {
     if (GameObject.Find (ObjectiveName) != null) {
             doOnce = true;      
     } else {
          if(doOnce == true){
                 doOnce = false;
                 messageObject.gameObject.SetActive(true);
                 messageText.text = myString;
          }
     }
  }

It looks as if it should work, maybe use a bool to explicitely control the condition

if (!IsThisThingAlreadyAssigned) { ObjectiveTHing = GameObject.Find (ObjectiveName); IsThisThingAlreadyAssigned = true;

}
