Looping Animation Event to only fire once?

Question

Hey all,

I have an Animation that is on a loop, however within this Animation is an event which I wish to fire off only once, it fires of the ShowMe function, on every loop, and ideally this would only happen one.

How can I do this?

I'm using code found here: http://forum.unity3d.com/threads/177...o-do-subtitles

  var myStrings : String[];    
         var curString : int = 0;    
         var displaying : boolean = false;    
         var myStyle : GUIStyle;
          
         function ShowMe(hit : int)
             {
                curString = hit;
                displaying = true;
                yield WaitForSeconds((myStrings[curString].length / 10) + 1);
                displaying = false;
             }
          
         function OnGUI()
             {
                if (displaying) {
                   GUI.Label(Rect(20, Screen.height - 80, Screen.width - 40, 60), myStrings[curString], myStyle);
                }
             }

Thanks, Josh.

The easiest way is to track if you've fired ShowMe() with a variable:

 var showMeHasHappened: boolean = false;
     
 function ShowMe(hit : int) {
     if (!showMeHasHappened) {
         curString = hit; 
         showMeHasHappened = true;
         displaying = true;
          yield WaitForSeconds((myStrings[curString].length / 10) + 1);
          displaying = false;
     }
 }
