Planetarium

A simple simulation of the Solar system using Java's Graphics2D.

Running the app

Comes in two modes:

• normal mode, which supports 8-bit alpha
• safe mode, which supports 1-bit alpha

To run the app either use the premade .bat files, or run it as regular jar:

• For the normal mode: java -jar planetarium.jar
• For safe mode: java -jar planetarium.jar -safemode.

How to use it

The app is controlled using the mouse and the following keys:

• F1 opens the help window

• F2 adds a star

• F3 adds a planet

• F4 adds a satellite

• N switches visibility of names

• O switches visibility of orbits

• R switches visibility of radious lines between children and parents

• D switches debug mode

• PAUSE pauses the app

• ESC quits the app

Notes:

• After pressing an 'add object' key, all already added objects stop their movement and the cursor image changes, indicating that one is about to a new object. Then one should click with the mouse wherever they may like their new object to be or press ESC to cancel the operation
• The sources are a bit outdated compared to the binary release, but, alas, I couldn't find the latest ones
• Always exit using the ESC key, or one would have to close the app through the Task manager
