I have just added the raw beginnings of a Java client library and
trivially-simple Swing GUI demo under scripts/java/demo/FGClient/.
Here's the Java code to connect to a FlightGear process and increase
the current altitude by 1000 feet:
FGConnection fgfs = new FGConnection("localhost", 9000);
double altitude = fgfs.getDouble("/position/altitude-ft");
fgfs.setDouble("/position/altitude-ft", altitude + 1000);
fgfs.close();
The demo application displays the current altitude, longitude, and
latitude in a small GUI window, and uses a separate thread to update
the values every second. To use it, try these commands:
fgfs --telnet=9000
java FGFSDemo localhost 9000
I might develop this into a remote instructor's panel, a full
configuration GUI, a remote-control module for weather and other
environment parameters, or any combination of these. Contributions
are welcome, of course.
All the best,
David
