actionscript 3 - as3 ARRAY SHIFT - the End of array now what? -


i having alphabet go on , off screen. using array shift go next letter. when last element of array, letter z, how can go beginning?

another example if had array of pictures , after done viewing last 1 code take begining again , start viewing there.

here code need set shift zero. 

var letter:movieclip; function fl_mouseclickhandler_2(event:mouseevent):void {     if(letter)      {         var gone:movieclip = letter movieclip;         tweenmax.to(letter, 1, { x:0 ,  ease:back.easeout, oncomplete:removeletter});         function removeletter(){              removechild(gone);         }      }     if(alphabet.length!=0)     {           letter = new alphabetletter();         addchild(letter);         /// key code line uses shift          letter.letter.text = alphabet.shift();            tweenmax.fromto(letter, 2, {x:stage.stagewidth}, {x:stage.stagewidth/2-letter.width, ease:expo.easeout});     }     else     {            //// tried not work                       alphabet.unshift(27);     }      /// code use here set array beginning?        if(alphabet.length==0)     {             alphabet.shift = 0; /// ???     }

shift() removes element array cannot unless keep somewhere else put in array when need again.

you had better use index variable find right element in array without modifying it: if index value larger 26, start @ 0 again.

or, use push() put letter @ end of array after shifting. way array never gets empty.
