    AS3 101: OOP Introduction – BasixPreview
    12 shares
    Twice a month, we revisit some of our readers’ favorite posts from throughout the history of Activetuts+. This week’s retro-Active tutorial, first published in October 2010, is an introduction to object-oriented programming in AS3. Don't forget to check out the other AS3 101 tutorials! Object-Oriented Programming is a bit of a hot topic. More and more programming languages are cropping up that support it (Ruby, for example), and more and more languages that previously didn't support Object-Oriented Programming (OOP for short) have been released with versions that do, like PHP and ActionScript. Some languages only work if you utilize the whole OOP thing to begin with, like Java and Objective-C. It's actually been around for a long time, but came into the limelight in the 1990's primarily due to its advantages with programming GUIs and the rise of C++ and Objective-C. Wikipedia has an interesting section on the history of OOP, which is a great place to start learning. Read More…
