How to animate arrays?

programming flash
1

I successfully created a menu using an array. But after researching and using other custom classes, I can’t figure out how to animate arrays. The animation is simple; I want each of the buttons fade in one at a time. Any pointers on how can I accomplish this? Note, I’m following Learning Actionscript 3 book, so I created few classes like it says in the book.

Thank you so much in advance.


/* Index */

package com {
    
    import flash.display.MovieClip;
    import flash.events.Event;
    import fl.transitions.Tween;
    import com.greensock.TweenLite;
    import com.NavBar;
    
    
    public class Index extends MovieClip {
        
        private var _logo:MovieClip = new Logo();
        private var menuData:Array = ["About", "Work", "Contact"];

        public function Index():void {
            
            _logo.x = _logo.y = 10;
            this.addChild(_logo);
            TweenLite.from(_logo, 1, {alpha:0});
            
            var navBar:NavBar = new NavBar(this, menuData);
            navBar.x = 187;
            this.addChild(navBar);
        
        }
    }
}



/* NavBar */

package com {
    
    import flash.display.MovieClip;


    public class NavBar extends MovieClip {
        
        private var _app:MovieClip;
        private var _menuData:Array;
        
        public function NavBar(app:MovieClip, menuData:Array) {
            _app = app;
            _menuData = menuData;
            build();
            }
        
        private function build():void {
            
            for (var i:uint; i < _menuData.length; i++) {
                
                var menuBtn:MenuButton =
                new MenuButton(_menuData*);
                menuBtn.x = 20 + (menuBtn.width + 2) * i;
                menuBtn.y = 83;
                menuBtn.width = 75;
                addChild(menuBtn);
                
            }
        }
    }
}



/* MenuButton */

package com {
    
    import flash.display.MovieClip;
    import flash.text.TextField;
    import flash.events.MouseEvent;
    import flash.events.Event;
    import com.greensock.*; 
    import com.greensock.easing.*;
    
    
    public class MenuButton extends MovieClip {
        
        public var _label:TextField;
        
        public function MenuButton (labl:String) {
            _label.text = labl;
            _label.mouseEnabled = false;
            buttonMode = true;
            useHandCursor = true;
            addEventListener(MouseEvent.CLICK, onClick, false, 0, true);
            addEventListener(MouseEvent.MOUSE_OVER, onOver, false, 0, true);
            addEventListener(MouseEvent.MOUSE_OUT, onOut, false, 0, true);
            }
        
        private function onClick(evt:MouseEvent):void {
            trace(_label.text);
            }
        
        private function onOver(evt:MouseEvent):void {
            TweenMax.to(_label, 0.5, {colorTransform:{tint:0xff0000, tintAmount:0.5}});
            }
        
        private function onOut(evt:MouseEvent):void {
            TweenMax.to(_label, 0.5, {colorTransform:{tint:0x333333, tintAmount:0.5}});
            }
        
    }
