- added extra bindings
- reworked the view axis (usually bound to the hat); to move at a better rate.
- trim to elevator position. When selected this will remember the current position and when the joystick is centered it will apply this as the trim. Very useful for carrier approaches; and also it helps to do something that is much easier with loaded controls when you can feel the pressure being reduced by the operations of the trim switch
- Engines control now use the same axis methods as the flight controls; which allows for these to have an inverted checkbox.
- Change the axis combo boxes to instead show a popup dialog (much like the button config). This is better because the items can be grouped sensibly.
- Changed the way that the "all engines" controls work - the dialog binds these to a "engines/XXXX-all" for which there is a listener in controls.nas which propogates over all engines.
- Added extra bindings to both the buttons and the axis dialogs.
- moved the "None" button to the bottom and renamed it to the more comprehensible "Remove assignment"
At the suggestion of Gilberto AGOSTINHO, add
button bindings for throttle, mixture and prop
to the joystick configuration dialog.
Specific use-case is users of game-pads, but also
useful to users with a single throttle axis on their
joystick.
- Since joystick.PropertyScaleAxis instances have a 'prop' attribute
indicating the property name, it seems logical to have
joystick.PropertyScaleAxis.parse() set this attribute based on the
property name in its argument ('p').
- This commit also tries to improve readability by using a 'bindingNode'
variable instead of repeatedly calling 'p.getNode("binding", 1)'.
- Commit 5bcf58c7d6 forgot to set the
'inverted' attribute when there was no 'factor' node in the argument's
'binding' node. Fix this.
- Also copy the argument's 'factor' value to the 'factor' instance
attribute for consistency, since joystick.PropertyScaleAxis instances
have such an attribute initialized in the constructor.
As far as I can tell, the dead-band setting belongs to <axis> nodes, not
to <binding> nodes using property-scale. This can be seen in
do_property_scale()'s definition (flightgear/src/Main/fg_commands.cxx)
as well as in fgdata/Docs/README.Joystick.html.
joystick.PropertyScaleAxis creates <dead-band> nodes as children of
<binding> nodes in generated joystick binding files under
$FG_HOME/Input/Joysticks which, AFAICT, are completely useless and thus
confusing. The <dead-band> nodes should be created at a different level
to be effective (cf. FGJoystickInput::postinit() in
flightgear/src/Input/FGJoystickInput.cxx).
This commit removes the 'deadband' attribute from
joystick.PropertyScaleAxis, since it has nothing to do there IMHO.
As can be seen in do_property_scale()'s definition in
flightgear/src/Main/fg_commands.cxx, property-scale rightfully uses a
default factor of 1.0. However, if a joystick axis' property-scale
binding has no 'factor' node defined, and one opens the joystick
configuration dialog, then PropertyScaleAxis.parse() creates an empty
'factor' node that implicitely gets a value of 0. This method is called
by joystick.readConfig() when the joystick-config dialog is opened. This
has the effect of rendering the corresponding joystick axis inoperant.
How to reproduce the bug:
- take a joystick such as the SAITEK CYBORG 3D USB, with its default
binding file from
fgdata/Input/Joysticks/Saitek/Cyborg-Gold-3d-USB.xml (this file uses
property-scale for the aileron, with no explicitely defined factor);
- start FlightGear; move the joystick left or right while looking at
the plane wings -> the ailerons move, it works fine;
- now, open the joystick-config dialog and do the same test -> the
ailerons don't move anymore and the 'Aileron' value at the bottom of
the dialog stays at 0 (0.0 or -0.0...). Just opening the dialog to
test the joystick has "corrupted" its setup! This is very confusing
for users.
This fix corrects the problem by avoiding the apparently unneeded
creation of an empty 'factor' node when there is none inside the
<binding>. An alternative would be to create a 'factor' node with value
1.0. In any case, if someone later expands the joystick-config dialog to
allow modification of property-scale's factor, he should make sure to
use a default value of 1.0!
