Moving from Flash AS2 to Flash AS3: Button Press

Lately, I’ve begun dedicating my time towards learning Actionscript 3.0. I’ve been told that Actionscript 3.0 is a bit tricky, but very powerful once you get the hang of it. However, when I came across a simple button press, I realized this wasn’t going to be a walk in the park.

The simple button press is probably one of the most used features for Flash users. With Actionscript 3.0, this has changed quite a bit. This is why this tutorial will directly focus on just that.

Getting Started with AS3: Button Press

The AS3 code below will show you how to add interactivity to a button using ActionScript 3.0.  It will also give you a glimpse of how the structure of ActionScript 3.0 has changed the face of ActionScript…for the better.

AS3 Code

//imports the necessary AS events
//attaching mouse events to the button on stage
rssButton.addEventListener(MouseEvent.CLICK, rssClick);
rssButton.addEventListener(MouseEvent.MOUSE_OUT, rssMouseOut);
rssButton.addEventListener(MouseEvent.MOUSE_OVER, rssMouseOver);
rssButton.addEventListener(Event.ENTER_FRAME, onEnterFrames);
//Properly declaring variable
var box_color_play:Number;
//On mouse clicked function
function rssClick(event:MouseEvent):void {
eventNotice.text = "MOUSE CLICKED";
//On mouse out function
function rssMouseOut(event:MouseEvent):void {
eventNotice.text = "MOUSE OUT";
box_color_play = 0;
//On mouse over function
function rssMouseOver(event:MouseEvent):void {
eventNotice.text = "MOUSE OVER";
box_color_play = 1;
//Function in place used for on ENTER_FRAME event animation
function onEnterFrames(event:Event)
if ((rssButton.box_color.currentFrame != rssButton.box_color.totalFrames) || (rssButton.box_color.currentFrame != 0)) {
if (box_color_play == 1) {
if (box_color_play == 0) {

  1. in as3 wat is the code for gotoAndPlay and nextFrame because i can’t use the bone and 3d tool in as2

  2. This is nearly exactly what I am looking for.

    I need a button to link to a URL is this possible with this file?

    our help is much appreciated.


  3. Great button and tutorial. One question, do new buttons not show the hand when you hover over them? anyway to get the hand back?


  4. Never mind my last question. I figured it out.

    // if you want a hand cursor
    rssButton.buttonMode = true;
    rssButton.useHandCursor = true;

  5. This is truly excellent tutorial of a Mouse Button rollover, click, etc. I had an excellent time creating button out of this!
