Combining functions in AS3

Posted by amandar

A friend of mine recently shared this technique with me, and I thought it was so cool I decided to post it up here.

If you have a lot of buttons in a project and they all have roll over, roll out and click states, your action script is going to be cluttered with functions. For example, this is how I was initially taught to have a single button with an on off and click state:

button_mc.buttonMode = true;
button_mc.mouseChildren = false;
button_mc.addEventListener(MouseEvent.ROLL_OVER, btnOver);
button_mc.addEventListener(MouseEvent.ROLL_OUT, btnOut);
button_mc.addEventListener(MouseEvent.CLICK, btnClick);

function btnOver(e:Event){
e.target.gotoAndStop(2);
}
function btnOut(e:Event){
e.target.gotoAndStop(1);
}
function btnOver(e:Event){
navigateToURL(new URLRequest("http://www.google.com"), "_self");
}
