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.
There's now an internal event handler for taking care of device addition
and removal, and a public event handler for dealing with device input
events in various contexts In particular, so the clients can check for
the escape key.
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.
The mouse bound to movement axes works (though signs are all over the
place, so movement direction is a little off), and binding F10 (key 68)
to quit works :)
Each axis binding has its own recipe (meaning the same input axis can be
interpreted differently for each binding)
Recipes are specified with field=value pairs after the axis name.
Valid fields are minzone, maxzone, deadzone, curve and scale, with
deadzone doubling as a balanced/unbalanced flag.
The default recipe has no zones, is balanced, and curve and scale are 1.
Hot-plug support is done via "connections" (not sure I'm happy with the
name) that provide a user specifiable name to input devices. The
connections record the device name (eg, "6d spacemouse") and id (usually
usb path for evdev devices, but may be the device unique id if
available) and whether automatic reconnection should match just the
device name or both device name and id (prevents problems with changing
the device connected to the one usb port).
Unnecessary enum removed, and the imt block struct moved to imt.c
(doesn't need to be public). Also, remove device name from the imt block
(and thus the parameter to the functions) as it turns out not to be
needed.
in_bind is only partially implemented (waiting on imt), but device
listing, device naming, and input identification are working. The event
handling system made for a fairly clean implementation for input
identification thanks to the focused event handling.
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).
The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.
keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).
For the mouse in x11, I'm not sure which is more cooked: deltas or
window-relative coordinates, but I don't imagine that really matters too
much. However, keyboard and mouse events suitable for 2D user interfaces
are sent at the same time as the more game oriented button and axis events.
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.
I had forgotten that _size was the number of rows in the map, not the
number of objects (1024 objects per row). This fixes the missed device
removal messages. And probably a slew of other bugs I'd yet to encounter
:P
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).
At the low level, only unions can cause a set to grow. Of course, things
get interesting at the higher level when infinite (inverted) sets are
mixed in.
Instead of printing every representable member of an infinite set (ie,
up to element 63 in a set that can hold 64 elements), only those
elements up to one after the last non-member are listed. For example,
{...} - {2 3} -> {0 1 4 ...}
This makes reading (and testing!) infinite sets much easier.
Most of the set ops were always endian-agnostic since they were simply
operating on multiple bits in parallel, but individual element
add/remove/test was very endian-dependent. For the most part, this
didn't matter, but it does matter very much when loading external data
into a set or writing the data out (eg, for PVS).
For now, the functions check for a null hunk pointer and use the global
hunk (initialized via Memory_Init) if necessary. However, Hunk_Init is
available (and used by Memory_Init) to create a hunk from any arbitrary
memory block. So long as that block is 64-byte aligned, allocations
within the hunk will remain 64-byte aligned.
