only updating number vars once

Question

when i have a variable reaching a certain number using an if statement, when it does it adds onto another number var (RoundNo += 1;) but it updates every frame the need( if(Spawned == SpawnRoundTotal){ ) is met, how can i make it only update the first frame where the need is met instead of every frame

thanks!

Use a boolean:

 var roundNum : int;
 var roundAdded : Boolean = false;
 
 function Update () {
        if(Spawned == SpawnRoundTotal) {
        //you made this conditional.  
              if(!roundAdded) {
              //Check to see if the Boolean is false.
                     roundNum++;
                     //If it is, add 1 and switch the value of the bool so that it is true.
                     roundAdded = true;
              }
         }
 }
