Step 4: Putting it all together

All right, we've got plenty of pretty radio buttons now, but the problem is, they don't do anything! Let's determine what our parent radio button group must be able to do.

First, it must be able to respond properly to the reportClick() function we defined earlier. This function must be able to select the clicked radio button, if it's not selected already.

We also need to be able to select a radio button by default. Finally, our parent clip should be able to tell us which radio button is selected.

Let's see how this all translates into actionscript. The old parts of the script are grayed out:


	labels = new Array();

	labels[0] = "potato";
	labels[1] = "potato";
	labels[2] = "potato";
	labels[3] = "Zimbabwe";
	numButtons = labels.length;

	vSpacing = 20;
	default = 3;

	for(i = 0; i < numButtons; i++){
		if(i != 0){
			radioButton0.duplicateMovieClip("radioButton" add i, i);
			this["radioButton" add i]._y += i*vspacing;
		this["radioButton" add i].label = labels[i];


	function reportClick(clicked){

		if(clicked != selected){



	function select(clicked){

		for(i = 0; i < numButtons; i++){

			this["radioButton" add i].gotoAndStop(1);

		this["radioButton" add clicked].gotoAndStop(2);
		selected = clicked;


	function getSelectedNum(){

		return selected;


	function getSelectedLabel(){

		return labels[selected];


Let's concentrate on the new parts of the script. We start off by defining the default selected option, in this case radio button #2. Moving down a bit, we make a call to the select function in order to select this default option.

What this function does, as you can see, is that it first loops through all of the radio buttons and unselects them one by one by sending them to their first frame. Next, it simply selects the appropriate radio button by moving it to its second frame, and makes sure to remember which radio button is selected by placing its number in the selected variable.

Our reportClick() function also uses the select() function. It simply checks if the radio button that called it was already clicked, and it not, it asks the select() function to select it.

Finally, we added two extra functions, getSelectedNum() and getSelectedLabel(), in order to retrieve information from our radio button group, that is, the number of the selected radio button and its label.

In the sample movie at the top, I named my group of radio buttons "groupOfRB", and simply made a call to groupOfRB.getSelectedNum() and groupOfRB.getSelectedLabel() in order to know what option you had selected. Knowing this, I produced appropriate feedback for the selected options.

I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
