Input driver can now have an optional init_cvars function. This allows
them to create all their cvars before the actual init pass thus avoiding
some initialization order interdependency issues (in this case, fixing a
segfault when starting x11 clients fullscreen due to the in_dga cvar not
existing yet).
keyhelp provides the input name if it is known, and in_bind tries to use
the provided input name if not a number. Case sensitivity for name
lookups is dependent on the input driver.
While the console command line is quite good for setting everything up,
the devices being bound do need to be present when the commands are
executed (due to needing extra data provided by the devices). Thus
property lists that store the extra data (button and axis counts, device
names/ids, connection names, etc) seems to be the best solution.
Now nothing works at all ;) However, that's only because the binding
system is incomplete: the X11 input events are getting through to the
binding system, so now it's just a matter of getting that to work.
Input Mapping Tables are still at the core as they are a good concept,
however they include both axis and button mappings, and the size is not
hard-coded, but dependent on the known devices. Not much actually works
yet (nq segfaults when a key is pressed).
kbutton_t is now in_button_t and has been moved to input.h. Also, a
button registration function has been added to take care of +button and
-button command creation and, eventually, direct binding of "physical"
buttons to logical buttons. "Physical" buttons are those coming in from
the OS (keyboard, mouse, joystick...), logical buttons are what the code
looks at for button state.
Additionally, the button edge detection code has been cleaned up such
that it no longer uses magic numbers, and the conversion to a float is
cleaner. Interestingly, I found that the handling is extremely
frame-rate dependent (eg, +forward will accelerate the player to full
speed much faster at 72fps than it does at 20fps). This may be a factor
in why gamers are frame rate obsessed: other games doing the same thing
would certainly feel different under varying frame rates.
For drivers that support it. Polling is still supported and forces the
select timeout to 0 if any driver requires polling. For now, the default
timeout when all drivers use select is 10ms.
This includes device add and remove events, and axis and buttons for
evdev. Will need to sort out X11 input later, but next is getting qwaq
responding.
The common input code (input outer loop and event handling) has been
moved into libQFinput, and modified to have the concept of input drivers
that are registered by the appropriate system-level code (x11, win,
etc).
As well, my evdev input library code (with hotplug support) has been
added, but is not yet fully functional. However, the idea is that it
will be available on all systems that support evdev (Linux, and from
what I've read, FreeBSD).
