These files take complexity out of the main joystick file, while
not adding much code. They also update the description (<desc>)
used by the Help->Joystick information dialog. All <nasal> code
is executed in the joystick's namespace, so variables and funtions
of the main file (popup()) can be accessed.
This allows to have generic axis/button definitions with aircraft
specific or aircraft class specific modification overlays. These
are also found in $FG_HOME, where they override global files. This
mechanism is desirable, because the Warthog is an A-10 replica, and
it should be possible to have an automatically loaded (1:1 mapped)
A-10 joystick config when flying the A-10, while using generic layouts
otherwise, or a specific helicopter overlay for helicopters etc.
Overlay files look exactly like joystick config files, except they
have no <name> and only specify actually differing elements. Axes
with <number> *need* a property index (e.g. <axis n="2">), which
usually corresponds to the <unix> value (i.e. n'th axis def in file).
Overlay files can contain a <nasal> block which is executed on
load. The files are to be named {$FG_ROOT,$FG_HOME}/Input/Joysticks/\
ThrustMaster/Warthog/{Joystick,Throttle}/{generic,helicopter,<aircraft>}\
.xml.
- to support "old-style" gear/flap control (operation as long as button
pressed/lever pushed -> b29/hurricane), let bindings not only report
up/down, but up (-1), stop (0), down (1).
- let controls.flapsDown() ignore "stop" so as to remain compatible with
prior behavior
- adapt all joysticks/aircraft (sigh)
- some minor cosmetics in joystick configs, such as indentation fixes
This file is in a rather bad state. Hence:
- remove doubled "rudder" settings
- fix & nasalify brake properties (/controls/gear/wheel[?]/brake, yet again)
- remove redundant index setting
- nasalify throttle (to allow more than 8 engines)
- nasalify flaps (to make flaps with more than 4 positions work)
- nasalify elevator trim (just for fun :-)
- fix syntax
- remove lots of trailing spaces
File tested by Jon-Eirik Pettersen
The following patch updates the ThrustMaster FCS joystick configuration. I have "Nasal-ized" the joystick bindings, drawing ideas from the Cyborg-Gold-3d-USB configuration file. I also changed some of the bindings, so the joystick setup is more like the default four-axis-joystick config. When I submitted the original config file, I had the hat switch bound to the rudder and elevator trim. Since the vast majority (all?) of the other joystick configs use the hat switch to control view direction, I think it would be best for the defaults for this joystick to conform to the rest in order to obey the "principle of least surprise" for the unsuspecting user.
