compile swfs rather than interpret .xml at runtime to create the content means
changing the file format: there are a load of good reasons to do this, and some
recent changes to Air that made it possible:</span></p>

created. You could use the function keyword to create pseudo functions, but
they weren’t of the type ‘function’ and couldn’t be

Subject: [Xerte] Xerte 3.0 Beta</span></p>
<div>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Hi,</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">There is a new beta of Xerte
3.0 to play with that you can download here: <a href="http://www.nottingham.ac.uk/xerte/xerte3.htm" target="_blank">http://www.nottingham.ac.uk/xerte/xerte3.htm</a>.
Xerte 3.0 is a complete rewrite of Xerte 2.x, using the Flex framework. There
is a major difference between this latest version and previous versions which I
wanted to say something about. Anyone following Xerte 3.0 developments, or
starting to use Xerte 3.0 to develop content needs to be aware of these
changes.</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"><br>
Xerte 3.0 now compiles .swf files. It creates, from your code, the actual .swf
file. There is no engine.swf unlike previous versions of Xerte 3.0 and Xerte
2.x. There are a number of good reasons why this was a good step to take. </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Xerte 3.0 is really an .mxml
editor and compiler using the Flex SDK to compile.swfs. You will need to
download and install the Flex SDK to use Xerte 3.0 (see instructions on the web
site). This means that Xerte 3.0 is quite clearly a tool for developers. It
also means that you are interacting with the Flex SDK directly, rather than
having our code parse and play your code. There are major performance benefits
to doing this, as well as getting access to all the benefits of the Flex SDK,
and it means that you can directly draw on all the Flex community’s
knowledge to create content with Xerte 3.0. Xerte 3.0 can compile many of the
examples on Adobe’s website and in the help system, as well as dozens of
samples already available from the Flex community. It also means you are
developing marketable skills in an established software development
environment.</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Flex is a very powerful,
flexible (pardon the pun) and extensible suite of tools. Xerte 3.0 aims to fill
a gap in the market of tools that sits somewhere between the hardcode
coder’s IDEs such as FlashDevelop or FlashBuilder, and something like
Xerte 2.x or Authorware, and as time goes on Xerte 3.0 will contain more and
more elearning specific features.</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Xerte 3.0 can build
‘normal’ flash applications. It can also build Air
applications, and package them into installers, and when the Flex 4.5 SDK is
complete, Xerte 3.0 will be able to build Mobile Applications. Being able to
target all these platforms is exciting, particularly the mobile Air
applications. Xerte 3.0 development is now closely following the development of
the Flex 4.5 SDK – when that is complete I’ll be able to finish
Xerte 3.0 and draw on all the new features in Flex 4.5.</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">There’s loads more to
say about Flex, but not enough time or space here. I’m going to start a
series of short tutorials to introduce you to the new environment and features,
and walk you through all the new components, and other stuff you’ll want
to know about: components, styles, skinning, states, effects, transitions, data
binding, using your own custom classes…</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">In the meantime, download
and install the beta, and let me know any comments,</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Thanks to Peter Huppertz -
who has made a major contribution,</span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;"> </span></p>
<p class="ecxMsoNormal" style="margin-left: 36pt;"><span style="font-size: 10pt;">Have fun.</span></p>
