FlightGear Launch Control: Difference between revisions

'''Fgrun''' is a graphical front end for [[FlightGear]], distributed and developed separately at http://sourceforge.net/projects/fgrun. However, it was included in officially distributed binaries for FlightGear, even though it is not technically a part the FlightGear program, like several other frontends (see also [[FlightGear related projects]]). Fgrun allows one to choose options more easily than with the [[Command_Line_Parameters|command line]]. (see also [[FlightGear 1.0 aircraft names for command line]])

The application has two main parts : a wizard to choose common options, and an advanced section where all options are available for advanced users.

Options choosen are automatically saved in a file and are reused the next time fgrun is restarted.

 

 

== The Wizard ==

The wizard appears to the user when fgrun is started. The first time, when no path are set, the first page is shown, otherwise, it jumps directly to the second page, but the first one is still accessible by hitting the "Prev" button.

The bottom of the wizard shows 6 buttons. From left to right :

In the first page, the paths needed by fgrun are recalled and can be set. If fgrun was installed with a binary package, either under Windows or Linux, these paths are normally initialized by the installation procedure.

The 'FG_ROOT' field is the full path to the FlightGear Base Package. It isn't the value of the $FG_ROOT ( or %FG_ROOT% under Windows ) environment variable. If this path is wrong, no [[Aircraft]] would be displayed and FlightGear won't run.

The 'FG_SCENERY' list is the path list to [[scenery]] folders. These folders usually have a 'Terrain', and optionally a 'Objects' , subfolders. One add a new path with the 'Add...' button. Priorities among folders are managed with the up and down arrows.

The 'Airports Cache' field shows the location of the file that stores the airport ids found in the scenery. It is faster to access that file than to scan scenery directories to build the airport list. It is possible to delete that file if things go wrong. That will force a new scan when the third page will be shown.

:If things goes wrong and FlightGear can't start anymore, and you want to start over with a bare installation, remove or rename the file named 'fgrun.prefs' located in the parent directory of the airport cache file. You will have to reenter path by hand, but the silly options you could have entered will be deleted.

The second page, usually the first page seen by users when starting fgrun, is the aircraft selection page. It shows the list of aircrafts found in FG_ROOT/Aircraft and the model of the selected aircraft, spinning.
