Astronomy Simulations and Animations
The original simulations are written in ActionScript 2.0. To open the .fla files, you’ll need an older version of Adobe Animate than the current version (19.1). You can download a trial version of Adobe Flash Professional CS4 here and open the .fla files with this. Also, Flash Professional CS6 can also open these files. Adobe doesn’t distribute Flash Professional anymore. The only way I’ve found to read the source files is by opening the .swf files in JPEXS Free Flash Decompiler .
To get to the code, go to Window -> Actions. The bottom-left panel should have the code hierarchy.
Here are instructions on how to develop and make changes to these simulations. If you’re using Windows, replace the forward slashes with back-slashes.
npm run serve
You can also use the
npm run dev command if all you want to do is
make a development build of a simulation without using
has an overview of this in How to run things locally.
npm run dev and
npm run serve watch the
src/ directory for file
Here are some blog posts I’ve made about these simulations:
There’s also the Conversion Guide that documents how to put together a new interactive.
Here are some links that may be helpful for development.
