This tutorial will document all the steps involved in creating a new Nasal module, Nasal is FlightGear's scripting language.


  • create a new plain text file under $FG_ROOT/Nasal/MODULE.nas
  • replace MODULE with the name for your new module (for example, use "test")
  • paste the following code into this file using a text editor (such as notepad on Windows)
# test.nas (save in $FG_ROOT/Nasal)
var mycode = func {
  print("My test module got loaded !");
}

_setlistener("/sim/signals/nasal-dir-initialized", mycode);


This piece of code defines a new function named "mycode" that just prints a message to the console. The _selistener call at the end of the snippet waits for the Nasal system to be initialized before the "mycode" function gets called.
