If two or more events are delivered in the same loop, the previous
implementation would count joystick motion multiple times. Fix this by
moving the joystick interpretation to occur once, after all the events
have been processed.
When joystick support is not present, `event_joystick_get_button` is not
declared in joy.h.

For historical reasons, the kcm_* arrays are smaller than the player's
configuration settings. Move the kcm_ arrays to be the first range
passed to zip, so that traversal does not exceed the array.
Fixes: d959eeca8f ("Use zip in kconfig to allow use of range-based for")
Add a comment in the #include directive to hide it from the PCH scanner,
since this file should not be included in the PCH. It is only used in
one file, and it is included under special circumstances. In
particular, it is included while inside a namespace.
Testing for buttons||hats||axes is equivalent to testing for
joysticks!=0, since SConstruct forces joysticks=0 when
buttons == 0 && hats == 0 && axes == 0. Remove tests of
buttons||hats||axes when those occur inside a test for joysticks!=0.
This ensures that an array is indexed by the appropriate type. Indexing
a mouse array with a joystick index is undefined behavior, and with this
change, such undefined behavior is now a compilation error.
lengthof was added to provide the size of C arrays. C++17 std::size is
now available, and can serve the same purpose. Remove the custom
lengthof.
The generated code is the same in both cases, other than the change in
line numbers caused by removal of the #include directives.
A new configurable joystick button binding is
introduced that opens the ingame menu, i.e. the
menu that appears when pressing the Escape key.
Fortunately, there was still enough space left
in the button binding maps for both games. The
configuration screen, however, needed to be
extended by a row to make room for the new
binding on d2x.
One known issue: When using an old player
configuration file, the menu button bindings
are initially set to J1 B1, because the unused
slots in DefaultKeySettings used to be
initialized that way. There's not much we can
do about that; the player needs to remove
these bogus assignments by hand. We can (and
do) prevent that from happening again, though,
by initializing new player files with correct
unmapped buttons.
In most menus, keyboard commands are synthesized
from controller buttons, leveraging the existing
axis-to-button translation.
Menu controls are currently fixed:
- button 0 (A) is confirm (Enter)
- button 1 (B) is cancel (Esc)
- button 2 (X) is switch (Space)
- button 3 (Y) is delete (Delete)
- axes 0 and 1 (main analog pad) maps to cursor keys
- all hats (D-pads) map to cursor keys
Title screens and credits can be confirmed
with any joystick button or axis motion too.
The automap code keeps a mostly-private secondary copy of control_info.
The change to reset control_info before the event loop reset the main
copy of control_info for the automap, not the copy that the automap
actually used. Fix this by passing the desired control_info to relevant
functions instead of always using the global variable Controls.
Fixes: c621a970c6 ("Reset kconfig counters once, before the event loop")
Special macros are used to pass information to
`generate-kconfig-udlr.py`. Provide default definitions for these
macros in `kconfig.ui-table.cpp`, and override them in the one build
where they need to be special. This enables `kconfig.ui-table.cpp` to
build cleanly when invoked from the command line in the compilation
database.
Each axis can act as two buttons in both ways.
For example, a player might map slide left and slide right to J1 -A1 and J1 +A1 as button presses instead of the slide L/R axis.
This is mostly to fix XBox 360 Controller Left and Right triggers. But it can work on every axis if the player wishes to bind them.
Slide left/right: A/D
Slide up/down: C/X
Accelerate/reverse: W/S
Afterburner (D2 only): Left-Shift
This produces the more FPS-typical WASD layout for
forward/left/back/right movement, and maps the crouch/stand bindings to
slide up/down. This ticket sat for longer than it should have (though
it never missed a release). Several competing designs were suggested,
but only one could be made active. After consideration, I used my own
bindings on the basis that, while some other bindings may be better,
every other configuration repurposed a classic weapons-fire key to
movement. Returning players who get the "new defaults" on a newly
created pilot profile might be very surprised by having their fire keys
move. Since these are only defaults, and can be rebound by the player
with a few minutes work, these defaults do not need to be perfect. They
just need to be an improvement over original Descent.
Delete unexpand-cpp-kconfig-key.py. It will likely never be needed, and
was added in the prior commit solely to have a file to recover if it
ever is needed.

Presently, user profiles are not portable between a build with
max_axes_per_joystick=0 and one with max_axes_per_joystick!=0.
Attempting to do so causes some buttons to be assigned to the wrong
action. Since the intended use case for max_axes_per_joystick=0 and
similar is to completely remove joystick support on a system that will
never use a joystick, this is acceptable for now. A future overhaul to
improve storage of user kconfig settings may fix this.
