This allows for the four combinations of shift and control. Not
bothering with alt because alt-f4 closes my xterm (bbkeys from the looks
of it: it grabs a bunch of Mod1-* keys).
This makes sure that some unchecked event doesn't cause a lockup.
However, blocking input is really not the way to go: need to implement a
state machine and use non-blocking event reads.
Or really, allow it if the user specifically requests it: the default is
blocked. Modern systems (particularly displays) do not really like
changing resolution, so doing so by default seems rather wrong.
Also fix a bug where despite supporting 32 buttons, only 18 were actually
supported, and a similar issue for the number of axes.
My saitek x52 has 34 buttons and 10 axes. Whee.
Once and for all: remove the default and move the Sys_Error outside the
switch (changing appropriate breaks to returns). Now gcc will let me know
when I forget to update the switch statements.
Johnny's number->J_AXISn mapping is preserved, but I had intended for any
key to be supported (J_AXISn was just to ensure free keys were available).
This gives both methods (and some range checking on the axis button
number).
First, this completely smashes joystick input: it will not work (though it
doesn't crash). This is because there is, as of yet, no means to configure
the system.
Each joystick axis has:
- per-axis amplification (both pre and post).
- per-axis offset (offset applied after pre-amp but before post amp)
- selectable destination:
- linear delta: position and angles (as before)
- axis button: if the value crosses the threshold, the given key is
pressed or released as appropriate.
The axis amplification still uses joy_amp and joy_pre_amp (and
in_amp/in_pre_amp), but now also has the per-axis settings.
The per-axis offset is most useful for axis buttons. For example, the xbox
360 controller triggers are analong but go "all the way to negative on 0
state". Offsetting the input keeps axis button thresholds simple.
Amplification and offset is applied before anything is done with the axis
value. The formula is:
joy_amp * in_amp * axis-amp *
(offset + value * joy_pre_amp * in_pre_amp * axis-pre_amp)
Axis button thresholds are very simple: if the sign of the value is the
same as the sign of the threshold and abs(value) >= abs(threshold), the
button is pressed. While multiple thresholds and keys can be placed on an
axis, only one can be pressed at a time. The threshold furthest from 0
wins.
Now the user can create and destroy IMTs at will, though currently
destroying IMTs is currently all or nothing (imt_drop_all).
An IMT is created via imt_create which takes the keydest name (key_game
etc), the name of the IMT (must be unique for all IMTs) and optionally the
name of the IMT to which the key binding search will fall back if there is
no binding in the current IMT, but must be already defined and on the same
keydest. This means that IMTs now have user determined fallback paths. The
requirements for the fallback IMT prevent loops and other weird behaviour.
Actual key binding via in_bind is unaffected. This is why the IMT name must
be unique across all IMTs.
The "imt" command works with the key_game keydest, but imt_keydest is
provided for specifying the active IMT for a specific keydest.
At startup, default IMTs are setup to emulate the previous static IMTs so
old configs will continue to work (mostly). New config files will be
written with commands to drop all of the current IMTs and build new ones,
with the bindings and active IMT set as well.
This fixes the status bar refresh issues in sw. The problem was that with
two viddef's hanging around, things got a little confused and recalc_refdef
wasn't getting into the renderer.
