Creating a mortgage calculator in Flash MX

by Sas Jacobs

Introduction

This tutorial covers creating a calculator that figures out mortgage repayments! A user enters the mortgage details and clicks a button to calculate their repayment. The source files demonstrate how it works.

You could use the same approach to build other types of calculators. The new UI components in Flash MX make it very easy to add elements such as buttons, combo boxes and radio buttons.

The tutorial is divided into the following parts:

• Background
• Structuring the movie
• Creating the user interface
• Initialising the movie
• Calculations
• Validation

This tutorial assumes that you know how to use Flash MX and that you're familiar with basic actionscript.
