I posed this same question to the AP list serve about 2 weeks ago. They suggested that eclipse and net beans are too complicated. BlueJ and drJava seemed to be the most highly recommended, and my students preferred drJava. I have been using JCreator but it is not as user friendly and is no longer free. They also suggested Greenfoot for the hierarchies in particular.

> BlueJ is an excellent simple Java IDE (compiler) for learning Java. NetBeans is another free Java IDE, and I think the Alice team has been working on a NetBeans plug-in for Alice 3. Both IDEs are available for Windows and Mac. Otherwise you can use the javac command-line compiler that comes with the JDK (Java Development Kit). It's not as fun to use a command-line compiler, but it is in some sense the simplest solution.

I just wanted an object that was essentially long, short and skinny. I'm sure there is a better object, I didn't work very hard at looking. Maybe a billboard with a long, short image would work well.

Because of the quirks of the 3-D text I had to check to see if the car was in front of one edge and behind the other. It had to do with how I turned them either 90? or 270? when positioning them. You'd probably have the same issue with a billboard. You might want to check distance from the edges for more accuracy.

> That is an interesting and difficult question? Ask the student to think about it this way, how do they know when they have walked into the view of a camera that is pointed in their general direction.

> Virtually impossible, unless there has been some indicators for the students to let them know that they are now in view, i.e. a sign that tells them "You are now in view of the camera" and / or another sign that tells them "You are now leaving the view of the camera". So what they might do is put a marker in the center of the camera view, make it invisible, figure out how far to the left or right of the marker the object can be and still be in camera view, and then check the distance:

> For example, the student figures out that an object can be 2.5 meters to the left or 2.5 meters to the right of the marker and still be in the camera view. So the conditional statement will be something like

> There are some assumptions here, that the obj and the marker are in line, and the camera is static (not moving)
>
> If the object is not in line with the marker than the distance value may have to be tweaked?
>
> If the camera is moving, than set the marker's vehicle to be the camera, so that as the camera moves, the marker moves with it, maintaining its relative position.

> Let me know if you have any other questions. I am also going to post this question to the Alice Educator's Mailing list to see if what other solutions are out there.
