ui/analogipt.cpp: Fixed bar graph display for fields with ranges that wrap through zero. emu/inputdev.cpp: Separateed analog axis deadzone and switch threshold settings, reduced default deadzone, and fixed a potential division by zero if the deadzone and saturation settings are equal. emu/ioport.cpp: Fixed behaviour of absolute analog fields where range passes through zero - it previously only worked for specific combinations of mask, minimum and default. Removed a workaround from universal/getaway.cpp that is no longer necessary. emu/input.cpp: Fixed unintuitive behaviour when an absolute field is assigned an OR combination of a relative control folled by an absolute control (e.g. Mouse X or Joy 1 LSX). Also fixed reading axis input sequences where an axis code is followed by a switch code (these can only be produced by manually editing configuration files, not through MAME's UI), and fixed the returned type when multiple relative axes sum to zero. osd/modules/input_dinput.cpp: Fixed hat switches being stuck in up position when input is suspended in the background taito/taitoio_yoke.cpp: Give throttle control a distinct type, and don't auto-centre. osd: Added option to select MIDI provider module (currently only PortMidi and the dummy module are available). Also put various things in namespaces, and fixed builds including SDL sound module with native Windows OSD. emu/validity.cpp: Added check to catch I/O port fields using UI input types. emu/inpttype.ipp: Renamed inputs that were causing confusion. "Bill" and "Track" were causing confusion for translators and hence likely causing confusion for many users, especially those who are not native English speakers. "Track" as an abbreviation for "Trackball" was frequently being mistranslated, e.g. in the sense of a CD track selection button or even in the sense of a railway track. There's no reason to abbreviate it. "Bill" in the US English sense as a banknote is too ambiguous and was causing confusion for translators. It's better to use the less ambiguous "Banknote". Corrected Greek translations of "Trackball". Don't run GitHub Actions on issue template changes.

OSD controls
|
|
------------
|
|
|
|
There are three types of controls that the OSD can provide as potential
|
|
input devices: digital controls, absolute analog controls, and relative
|
|
analog controls.
|
|
|
|
Digital controls have only two states: on or off. They are generally
|
|
mapped to buttons and digital joystick directions (like a gamepad or a
|
|
joystick hat). The OSD layer must return either 0 (off) or 1 (on) for
|
|
these types of controls.
|
|
|
|
Absolute analog controls are analog in the sense that they return a
|
|
range of values depending on how much a given control is moved, but they
|
|
are physically bounded. This means that there is a minimum and maximum
|
|
limit to how far the control can be moved. They are generally mapped to
|
|
analog joystick axes, lightguns, most PC steering wheels, and pedals.
|
|
The OSD layer must determine the minimum and maximum range of each
|
|
analog device and scale that to a value between -65536 and +65536
|
|
representing the position of the control. -65536 generally refers to
|
|
the topmost or leftmost position, while +65536 refers to the bottommost
|
|
or rightmost position. Note that pedals are a special case here, the
|
|
OSD layer needs to return half axis as full -65536 to + 65536 range.
|
|
|
|
Relative analog controls are analog as well, but are not physically
|
|
bounded. They can be moved continually in one direction without limit.
|
|
They are generally mapped to trackballs and mice. Because they are
|
|
unbounded, the OSD layer can only return delta values since the last
|
|
read. Because of this, it is difficult to scale appropriately. For
|
|
MAME's purposes, when mapping a mouse devices to a relative analog
|
|
control, one pixel of movement should correspond to 512 units. Other
|
|
analog control types should be scaled to return values of a similar
|
|
magnitude. Like absolute analog controls, negative values refer to
|
|
upward or leftward movement, while positive values refer to downward
|
|
or rightward movement.
|
|

|
Game controls
|
|
-------------
|
|
|
|
Similarly, the types of controls used by arcade games fall into the same
|
|
three categories: digital, absolute analog, and relative analog. The
|
|
tricky part is how to map any arbitrary type of OSD control to an
|
|
arbitrary type of game control.
|
|
|
|
Digital controls: used for game buttons and standard 4/8-way joysticks,
|
|
as well as many other types of game controls. Mapping an OSD digital
|
|
control to a game's OSD control is trivial. For OSD analog controls,
|
|
the MAME core does not directly support mapping any OSD analog devices
|
|
to digital controls. However, the OSD layer is free to enumerate digital
|
|
equivalents for analog devices. For example, each analog axis in the
|
|
Windows OSD code enumerates to two digital controls, one for the
|
|
negative direction (up/left) and one for the position direction
|
|
(down/right). When these "digital" inputs are queried, the OSD layer
|
|
checks the axis position against the center, adding in a dead zone,
|
|
and returns 0 or 1 to indicate its position.
|
|
|
|
Absolute analog controls: used for analog joysticks, lightguns, pedals,
|
|
and wheel controls. Mapping an OSD absolute analog control to this type
|
|
is easy. OSD relative analog controls can be mapped here as well by
|
|
accumulating the deltas and bounding the results. OSD digital controls
|
|
are mapped to these types of controls in pairs, one for a decrement and
|
|
one for an increment, but apart from that, operate the same as the OSD
|
|
relative analog controls by accumulating deltas and applying bounds.
|
|
The speed of the digital delta is user-configurable per analog input.
|
|
In addition, most absolute analog control types have an autocentering
|
|
feature that is activated when using the digital increment/decrement
|
|
sequences, which returns the control back to the center at a user-
|
|
controllable speed if no digital sequences are pressed.
|
|
|
|
Relative analog controls: used for trackballs and dial controls. Again,
|
|
mapping an OSD relative analog control to this type is straightforward.
|
|
OSD absolute analog controls can't map directly to these, but if the OSD
|
|
layer provides a digital equivalent for each direction, it can be done.
|
|
OSD digital controls map just like they do for absolute analog controls,
|
|
except that the accumulated deltas are not bounded, but rather wrap.
