An Actor Class

Java Gaming for the Masses

Implementing a Scene Management System

We're going to put together a few demos in this set of notes. Some of the classes have already been discussed already. For those we will provide links to their source code. Some classes are entirely new, and perhaps they should be included here in their entirety. At the very least, though, we need to be able to distinguish between them.

Here's a Scrollable Scene demo.

Please note that you need j2sev1.4 where you run it.

What you need:

You also need (Use your appletviewer from a host with j2sev1.4).

The location of these files is: 

/l/www/classes/a348/t540/spr2002/lectures/code/Three
Web-wise that means:

The scene is also relying on the following two pictures: For the next example the code is in Four.

Can you identify those that we have been using over and over again?

If you do, you might be thinking of putting them into a package (and/or a .jar file).

The last example's called Creating a Wrapped Scene.

The code is in Six.

We're having 1.4 installed in the classroom this Friday.

We're trying to install the Java 3D API also.

Here's a recent book entirely on-line.
