Creating an animation with JAWAA

THIS PAGE IS OLD AND OUT OF DATE AND USES AN OLD VERSION OF JAWAA. SEE JAWAA 2.0 for the latest version, commands, and examples.

The tool JAWAA allows you create animations easily on a web page. It uses JAWAA commands that can be either typed into a file or produced as output from your program.

You'll need two files to run an animation. One is a file of JAWAA commands that has a .anim extension. The second file is a .html file that refers to the .anim file and JAWAA source.

Getting Started

Here is a list of JAWAA COMMANDS
Here is a JAWAA Tutorial, including sample html and anim files for you to copy.
To get started, copy these sample html and anim files. The tutorial above explains how to modify them.
- jawaa_tutorial.anim
- jawaa_tutorial.html

Notes

Always display the JAVA Console Window with your browser when running your JAWAA program. It will list the JAWAA commands as they are run. If it halts early, you will see the command that caused the problem.
You can change the speed of your animation. Move the control all the way to the right to see it run at high speed.
You can change the size of your animation by changing the height and width specified in the APPLET tag of your html file. For example, the following tag specifies a 640x480 sized animation.
```
<APPLET
 CODEBASE="http://cgi.cs.duke.edu/~rodger/jawaa"
 CODE="jawaa/app/JawaaGui.class"
 WIDTH=640
 HEIGHT=480>
</APPLET>
```
You can actually use any color acceptable to Netscape within JAWAA, but you cannot specify it by name. Instead you must specify it as an RGB triple. This applet helps you translate between the named color and the RGB triple needed by JAWAA. For example, the following sets the color to purple:
```
line l1 20 25 90 25 (128,0,128)
```

Sample Animations

Note: Copy the .html file from the tutorial to get started, not these.
