Don, thanks. In Java, you can extend a class with the only new thing being a new constructor that sets all the property values the way you want them. Is there a way to do this in Alice 3?

<div class="" style="word-wrap:break-word; line-break:after-white-space">James,
<div class="">You are correct, that because the Alice 3 Export function exports essentially a Java class, methods, functions, class properties of the class will be exported. But not the particular characteristics fo an object of that class.</div>
<div class=""> </div>
<div class="">If Alice allowed the creation of properties and variables of the type adultPersonResource, teenPersonResource, childPersonResource, etc, then one could create a class property of that resource with the specific values of the avatar, which would
be exported with the class. That may be worth investigating for future releases.</div>
<div class=""><br class="">
</div>
<div class="">But I did come up with a work-around, a hack, actually ;-) Using the TeenPerson class</div>
<div class=""><br class="">
</div>
<div class="">1) Create a method for the person class, name it something like setMyResource…</div>
<div class="">2) Inside that method, use the setTeenPersonResource to build the avatar. (This will not change the appearance of the avatar in the scene until the method setMyResource is called). See the attached screen shot.</div>
<div class="">3) You may now export this class, and the setMyResource method, with the specific values for the avatar will be exported as part of this method.</div>
<div class="">4) When you import this class into a new project, call the setMyResource method as the first line of code, and the avatar in the scene will take on the desired appearance at runtime.</div>
<div class=""><br class="">
</div>
<div class="">I have also attached a sample project that you might play with.</div>
<div class=""><br class="">
</div>
<div class="">It is a hack, but it is something until until we come up with a more elegant solution.</div>

<div class="" style="word-wrap:break-word; line-break:after-white-space">Hello, everyone. I have made the jump from Alice 2 to Alice 3. Is there any guide to Alice 3 for long-time users of Alice 2? I am hitting a problem right away. In Alice 2, I had each of
my students create an “avatar” using the He/she builder, export the object, and use it in every one of their homework assignments. I can’t find a way to export a carefully crafted person in Alice 3 for use in other projects. The class export system seems to
be completely different.
