In this tutorial we will learn how to load multiple images using actionscript 3 and xml. Let's see how we can do this! 1. Establish the project structure. Make the same folder hierarchy like in the image below: ro/sorin/utils/ contains the TextLoader class, we will use this class to load the xml file. If you want to fallow along you can download it TextLoader.as , place the file inside the utils folder. The other folders are self-explanatory. 2. Creating the xml file structure. The xml file looks like this: <?xml version="1.0" encoding="utf-8"?> <images> <image url="assets/images/img_01.jpg"/> <image url="assets/images/img_02.jpg"/> <image url="assets/images/img_03.jpg"/> <image url="assets/images/img_04.jpg"/> <image url="assets/images/img_05.jpg"/> </images> Every image tag contains the data for one image. The url is a attribute of the i...

We will build a menu witch is powered by an xml file; this offers a lot of flexibility because you can add/remove buttons by modifying the xml file and not by modifying the .fla file. The buttons will maintain they down state when clicked. We will not have any code on the timeline, all the code will reside in external classes, so it’s not only an xml driven menu it’s also coded in OOP style. We will use something called optional parameters ; they are parameters that have a default value. To better understand this, let look at a simple example. function sayMyName(name:String = "Sorin"):void { trace (name); } //We have a function with a parameter called name witch has a default value(Sorin), //if we call the function with no parameter passed to it the output will be Sorin sayMyName(); output: Sorin //if we call the function with a custom value("Elvis") the function will output Elvis sayMyName("Elvis"); output: Elvis Here is how the menu look...

In this tutorial we will build a button (in fact is a movieclip that acts like a button and we will not build a button, we will make a menu) that has an over state, an out state and a down state. Like the title says the button will stay in the down state when is clicked (selected) and because the selected button will look different from the others buttons the user will know exactly on what page is.This is how the menu will look: 1. Create a new file by going to File > New select Flash file (ActionScript 3.0) and click Ok. Save the file as myButton.fla. 2. Insert a new layer (Insert>Timeline>Layer), name the layers beginning from the top: actions and buttons . In the Property Inspector set the frame rate to 30. 3. Select the Rectangle tool set the stroke to none, pick a color (I have picked black) and on the buttons layer draw a rectangle. Set the measurements of the rectangle as fallows: width = 170, height = 40. Select the rectangle and press F8 to convert it to a MovieClip....
