Hi issanasr13,

The way I would do it is to set up an array of names for your pages, then increase and decrease a page number variable with a Left and Right key press, which will reference the pages in the array.

// Set up pages array
var pages_array:Array = new Array();
pages_array[0] = "home";
pages_array[1] = "about";
pages_array[2] = "links";

// initialise page number and name
var pageNum:Number = 0;
var pageName:String = pages_array[pageNum];

// set up key listener and Key class
var keyListener:Object = new Object();
keyListener.onKeyDown = onKeyDownHandler;
Key.addListener(keyListener);

// function to handle the key press
function onKeyDownHandler():Void {
  // store the key that has been pressed
  var keyCode:Number = Key.getCode();
  if (keyCode == Key.LEFT){
    // decrease the pageNum variable
    if (pageNum > 0){
      pageNum--;
      setPage();
    }
  } else if (keyCode == Key.RIGHT){
    // increase the pageNum variable
    if (pageNum < 2){
      pageNum++;
      setPage();
    }
  }
}

// function to handle the new page
function setPage():Void {
  pageName = pages_array[pageNum];
  trace("pageNum = " + pageNum);
  trace("pageName = " + pageName);
  // put some code here to load the new page
  // or goto a frame on the timeline, etc
  // based on the value of pageName
}

Hope this helps.
Paul

Thanks very much PaulLamonby for your help ..but i have one query about the last code

// function to handle the new page
function setPage():Void {
pageName = pages_array[pageNum];
trace("pageNum = " + pageNum);
trace("pageName = " + pageName);
this._parent._parent.attachMovie("page1")
this._parent._parent.attachMovie("page2")
}

It didn't work like this..what i should write instead of the last 2 lines
And by the way my pages are Movieclips(page1,page2 and page3..etc)
Thanks again

Hi issanasr13,

What timeline have you written the code on? This will determine what path you need to use to load the 'pages'. I suggest placing all your code on the _root timeline in frame 1.

You also need to use the correct parameters when using attachMovie(idName, instanceName, depth)

e.g. If your code is on the _root timeline, the code below will attach a movieClip from the library, with a linkage ID name of 'home' to the _root timeline. It will have an instance name of 'home_mc' and a depth relevant to the next highest available depth.

// Set up pages array
var pages_array:Array = new Array();
pages_array[0] = "home";
pages_array[1] = "about";
pages_array[2] = "links";

// initialise page number and name
var pageNum:Number = 0;
var pageName:String;

// function to handle the new page
function setPage():Void {
pageName = pages_array[pageNum];
var instanceName:String = pageName + "_mc";
this.attachMovie(pageName, instanceName, this.getNextHighestDepth());
}

// call the setPage function
setPage();

Regards
Paul
