new to CS4 can't write code on button like M8

[47redlands]

Hello I am new to CS4. I have been using Macromedia 8 and used to be able to write code on a button very easily. So click on the button and go the actions. But How do I do it in Cs4?

Thank you in advance.

By default CS4 (and now CS5) files are written in Actionscript 3, which doesn't allow you to put code on buttons or clips, only on frames (or in external class files). If you change your Publish Settings to Actionscript 2, you can write code on buttons.

If you want to do it the Actionscript 3 way, you place your button on the stage, give it an instance name in the Properties panel (let's say you call it myButton), and then in the same frame you add a listener and a function, a la:

myButton.addEventListener("click", doSomething);
function doSomething(e) {
    //code here
}

Or, if you want to follow more strict coding standards:

myButton.addEventListener(MouseEvent.CLICK, doSomething);
function doSomething(e:MouseEvent):void {
    //code here
}
