The Demise of Flash


Abobe’s Flash has been the dominate force for dynamic graphics, sounds and interactivity on the web for a very long time. The end of its reign, and the dawning of the HTML5 age, would appear to be nigh however – for several reasons, such as:

Proprietary nature

Flash is a completely proprietary piece of software – that is, the specific standards on which it is based have not been made available to the general public. This means that only Adobe software can run Flash applications, and consequently that Adobe has complete control over the decisions as to who gets to run their software. Some attempts at reverse engineering the standard in order to make compatible players for other systems have been done (such as UIRA), these were unsuccessful due to the ownership that Adobe maintained of Flash.


Now by requirements I don’t necessarily mean system requirements, but requirements made of the user before they can view Flash applications. This ties in loosely to the proprietary issue, but is more due simply to the fact that web browsers have advanced considerably since Flash was first envisaged. For most of Flash’s life there were no other really viable options for creating interactive online media – now, with the development of the HTML5 canvas spec, all modern browsers come equipped ready to render basically any kind of graphics a user could want. From basic 2D to full on, physics-driven 3D, the need for Flash is simply no longer there.

Stability and Security

In recent times Flash has been the subject of various security issues and (as is to be expected of any large piece of software) some crashing issues. Although HTML5 does not guarantee that these will be non-existent by any means, the point does count against Flash. In addition, with HTML5 being an open standard, security audits are easier to design, and easier to test to ensure that they are being followed (although not guaranteed to be correct).

So what next?

As mentioned previously, the up-and-coming replacement for Flash is the HTML5 standard. HTML5 is the fifth revision of the exceedingly popular HTML (Hyper Text Markup Language) standard which powers most of the web. HTML5 brings in a wide range of additions to the existing standard and provides for improved cross-platform capabilities, video, audio and (most importantly for our discussion) graphics via the <canvas> tag.

Now, most other HTML elements are rendered directly according to the tag and its mark up. The canvas tag, on the other hand, is designed to be rendered with the help of Javascript. This allows for dynamic graphics to be created using a language that most web designers have at least a passing familiarity with, using a tag supported by all modern browsers.

The capabilities of the canvas tag are proving to be vast – from basic 2D games (see my Asteroids clone for an example of this) to full-blown 3D environments (see TankWorld, for example). Any developer interested in producing cutting-edge, dynamic interactive online applications would do well to pick up at least a passing familiarity with it.

Once you’ve gone that far, you’ll most likely find that you’re driven to learn more. If you’d like an introduction to the basics check out the introduction to canvas and Javascript where I’ll start from the complete basics of canvas and Javascript. Follow the tutorials to learn everything from the setup all the way through to some basic animation.

    Dude, your asteroids clone is sick! I’m so “borrowing” it for my web site! with full attribution of course!
