Adding listeners for instances on other frames

Apr 14, 2012 10:42 AM

I'm trying to create a very standard menu, the type where there are links on each page that links to each other. So far I've put each menu page on a separate frame (total around 35 frames), and each link as its own instance/class. Originally I planned to create an array containing all the links like this:


var menuLinks:Array =


                            //Main menu - frame 1








                            //chapters menu - frame 2







                            //characters - frame 3








                            //options - frame 4







                            //function links - these exist on MULTIPLE frames/pages, eg options, characters, chapters all have backToMainLink





                            ]; //create array of links for menus


            currentPage = "main_menu";


            for each (var links:MovieClip in menuLinks)


                links.buttonMode = true; //set links to behave like button

                links.mouseChildren = false; //mouse over does not affect this instance's children

                links.addEventListener(MouseEvent.ROLL_OVER, onOver);

                links.addEventListener(MouseEvent.ROLL_OUT, onOut);

                links.addEventListener(MouseEvent.CLICK, onClick);



            function onOver(e:MouseEvent):void //apply glow to every link


      , 1, {glowFilter:{color:0xFFFFFF, alpha:1, blurX:10, blurY:10}}); //glow effect



            function onOut(e:MouseEvent):void //remove glow on link on mouse out


      , 1, {glowFilter:{color:0xFFFFFF, alpha:0, blurX:0, blurY:0, remove:true}}); //remove glow



            function onClick(e:MouseEvent):void


                currentPage =;


                if ( == "newStoryLink") { //if click newStoryLink







                } else if ( == "optionsLink") { //if click optionsLink

          , 0.2, {alpha:0, onComplete:menuRightSide.gotoAndStop, onCompleteParams:[45]}); //go to frame 45, options screen

          , 0.2, {alpha:1, delay:0.2});

                } else if ( == "charactersLink") { //if click charactersLink

          , 0.2, {alpha:0, onComplete:menuRightSide.gotoAndStop, onCompleteParams:[10]}); //go to frame 10, char screen

          , 0.2, {alpha:1, delay:0.2});

                } else if ( == "aboutLink") { //if click aboutLink

          , 0.2, {alpha:0, onComplete:menuRightSide.gotoAndStop, onCompleteParams:[180]}); //go to frame 180, about screen

          , 0.2, {alpha:1, delay:0.2});






Basically adding listener for every link, then simply telling AS what to do when I click the link regardless of what page I'm currently on.

However the problem is I realized listeners can't be added for links that exist on other frames other than frame 1, because they're null I think until AS flips to that frame.

So does anyone have an idea on how I should code this? Another challenge is some links (the ones at the bottom of the array) exist on MULTIPLE frames, but perform the exact same thing regardless of which page it was clicked on.

    You either need to assign the listeners in the frames where the objects are, or put the objects in the frame where the code is.  One way of attacking this is to have all your butons along the entire timeline asnd control their visibility as needed.


    Another way of approaching a design is to have everything in frame 1 instead of spreading things out along the timeline, using movieclips as your pages and controlling their visibility.


    If kGlad stops by and gives this a look he can offer a way of assigning the listeners from frame 1 even if the buttons are in other frames... has to do with assigning a listener for the stage redrawing for the new frame and then assigning the listeners.  You should find a posting he answered for this here somewhere in the last month.

    If you want to use a loop, then you portions of the array you have for the different frames... a "for each" approach isn't going to work since that array is for all frames.  You need to specify the starting and ending indices for the loop relative to each frame... as in...


    for(var i:uint=framestartIndex; i<=frameendIndex; i++){

    It is a loop that uses an index as the basis for counting, not much different from the one you have already, but it isn't looking for all of the elements in the array, just certain portions of them.  Since you would want to use only a portion of the array for each different frame, the index is set to target the portions of the array.  For your frame 1 you would use a framestartIndex value of 0 and a frame end index of 5, so that only the frame 1 links get assigned.


    You'll have to search for kGlad's posting, I don't keep track of them and cannot say if finding it will be easy.

    i couldn't tell what you're trying to do but i can tell from one of ned's messages that you might be trying to reference an object that exists on a frame that's not the same as the frame that contains your code.  and because of his message i suspect you're using a goto to navigate to the frame that contains that object and, after that goto executes, you want to reference the object on that frame.


    if all that's true, use the render event:


    function gotoF():void{





    function renderF(e:Event):void{

    // you can now reference yourobject that's in that goto target frame

    Within an array you can repeat as many things as you like. 


    If you have some links in every section, then you can probably get away with having just one of them that extends the length of the timeline so that you only need to assign the link in frame 1.
