Calibrating Controls

Some controls, in particular the accelerator and brake pedals of steering
wheels, may need calibrating before they will function properly with
Supermodel.
In order to calibrate a control, press 'b' when configuring the inputs and
follow the on-screen instructions carefully.
Several input-related settings are stored in the configuration file. Refer to

Troubleshooting
---------------
Common input-related problems are discussed below.
Problem:
No response while configuring inputs.
Solution:
Make sure the main window is top window, especially with the SDL input
system.
---------
Problem:
An attached controller is not recognized at all.
Solution:
- On the input configuration screen, press 'I' to see information about
the input system and check that the required controller is in the
list.
- If it is not in the list, check that it is plugged in and visible in
the operating system. If a controller is plugged in while Supermodel
is running, Supermodel will need to be restarted in order for it to
recognize the new controller.
- On Windows, if after checking the above points the controller is
still not in the list, try running Supermodel with the SDL input
system by specifying '-input-system=sdl' on the command line.
---------
Problem:
Unable to select a particular joysick axis when configuring a mapping.
Solution:
- This may mean that the joystick axis needs calibrating. This can be done by pressing
'b' on the configuration screen and following the instructions.
---------
Problem:
Steering wheel pedals are not being recognized.
Solution:
For some steering wheels where the pedals have been configured in a
'split axis' mode (ie. not sharing a combined axis), the values that
the pedals send are inverted. This means that without configuration
Supermodel will be unable to recognize them. To fix this, they should
be calibrated on the calibration screen in the same way as above.
---------
Problem:
XBox 360 controller trigger buttons cannot be triggered simultaneously
or no rumble effects.
Solution:
On Windows, make sure that you specify '-input-system=xinput'.

@ -865,12 +943,170 @@ Input Mappings
Input mappings are specified with strings that have their own internal syntax.
They may only be specified in the 'Global' section and are ignored elsewhere.
... TODO: write me
A mapping may be specified in one of the following three ways:
The complete list of input settings can be found in the settings index below or
KEY_XXX For a key XXX on a keyboard (eg. KEY_A, KEY_SPACE, KEY_ALT).
MOUSE_XXX For a mouse axis (X or Y), wheel, or button (1-5) (eg.
MOUSE_XAXIS, MOUSE_WHEEL_UP, MOUSE_BUTTON3).
JOY1_XXX For a joystick axis (X, Y, Z, RX, RY, RZ), POV controller
JOY2_XXX (1-4), or button (1-12) (e.g. JOY1_XAXIS, JOY3_POV2_UP,
... JOY2_BUTTON4).
Joysticks, including game pads and steering wheels, are numbered from 1 on up.
Their ordering is system dependent and if controllers are swapped between
invocations of Supermodel, then the ordering may change. If the number is
omitted then the mapping applies to all joysticks, eg. JOY_BUTTON1 means button
1 on any attached joystick.
In addition to the above, when using the Raw Input system on Windows (command
line option '-input-system=rawinput') it is possible to refer to a particular
mouse or keyboard by including its number in the mapping, eg. KEY2_A or
MOUSE3_XAXIS. This allows the independent mapping of dual mice or dual light
guns (which present themselves as mice to Supermodel) for 'The Lost World'.
Mappings may be combined with a plus '+' or a comma ',' and negated with an
exclamation mark '!'. The plus signifies that both mappings must be active to
trigger the input and the comma means that just one needs to be active. The
exclamation mark means that a mapping must not be active.
Of the above the comma is the most useful. It allows the mapping of several
different control methods to a single input. For example, both a keyboard and
a joystick could be mapped to the same input. When combining mappings in this
way, the ordering is important as mappings earlier in the list will take
precedence over later ones (see example 3 below).
When an axis is mapped to a digital input, its direction must be qualified with
a _POS or _NEG after the axis name. For example, JOY1_XAXIS_NEG indicates that
joystick 1 must be pushed left (negative direction) in order to activate the
input. Additionally, the following shortcuts are provided for some common
joystick axis directions:
JOY1_LEFT is the same as JOY1_XAXIS_NEG
JOY1_RIGHT is the same as JOY1_XAXIS_POS
JOY1_UP is the same as JOY1_YAXIS_NEG
JOY1_DOWN is the same as JOY1_YAXIS_POS
Another axis manipulator is _INV. This inverts an axis when it is mapped to an
analog input. JOY1_YAXIS_INV could be used for example to invert the y-axis
of joystick 1 in Star Wars Trilogy so that it acts like a plane's yoke.
Examples:
1. InputLeft = "KEY_LEFT,JOY1_LEFT"
Digital input InputLeft will be triggered whenever the left arrow key
is pressed or joystick 1 is pushed left.
2. InputStart1 = "KEY_ALT+KEY_S"
Both Alt and S must be pressed at the same time in order to trigger the
digital input InputStart1 (player 1 Start button).
3. InputSteering = "JOY1_XAXIS,MOUSE_XAXIS"
Analog steering can be controlled with either the joystick or by moving
the mouse. Due to the ordering used, the joystick will take preference
and so the mouse can only control the steering when the joystick is
released.
The complete list of input mappings can be found in the settings index below or
by generating a configuration file using '-config-inputs'.
Controller Settings
-------------------
Several settings are available to fine tune the way Supermodel handles
controllers.
Keyboard Settings:
The rate at which analog controls' values increase or decrease when controlled
by a key can be set with the InputyKeySensitivity option. It takes a value in
the range 1-100, with 100 being the most sensitive (fastest response) and 1
being the least sensitive (slowest response). The default value is 25.
The speed with which analog controls return to their rest or 'off' values after
a key has been released is configured with InputKeyDecaySpeed. This takes a
value in the range 1-200 and is expressed as a percentage of the attack speed.
The default setting is 50, which means that analog controls take twice as long
to return to their off values as they do to reach their maximum and minimum
values.
Mouse Settings:
For a mouse it is possible to specify a rectangular area in the center of
Supermodel's display within which the mouse is considered to be inactive. The
width and height of this zone is set with the options 'InputMouseXDeadZone' and
'InputMouseYDeadZone'. They are expressed as a percentage 0-99 of the width
and height of the display. The default value is 0 which disables this option.
Joystick Options:
Each joystick axis has a set of parameters that can be configured and these are
given below. The joystick number and axis name (X, Y, Z, RX, RY, or RZ) must
be substituted in for '**' like so: InputJoy1XDeadZone. If the joystick number
is omitted, then the option becomes the default for all joysticks, eg.
InputJoyYSaturation.
InputJoy**Deadzone: The dead zone of a joystick axis is the size of the zone
around its central or 'off' position within which the axis is considered to be
inactive. It is important to specify this since joysticks rarely return to
their perfect center when released. The dead zone is expressed as a percentage
0-99 of the total range of the axis and the default value is 2%.
InputJoy**Saturation: The saturation of a joystick axis is the point at which
the axis is considered to be at its most extreme position. It can be thought
of as a measure of the sensivity of the axis. Like the deadzone, it is
expressed as a percentage of the axis range but its value may be larger than
100, up to a maximum of 200. A value of 50 means that the joystick only needs
to be moved halfway in order for Supermodel to see it as fully extended.
Conversely a value of 200 means that when the joystick is at its extreme
position Supermodel will see it as only halfway. The default sensitivity is
100%, which corresponds to a 1-to-1 mapping. For playing driving games with a
game pad, it is sometimes a good idea to use a value larger than 100% so that
the steering feels less sensitive on a thumbstick.
InputJoy**MinVal, InputJoy**OffVal, InputJoy**MaxVal: Normally a joystick axis
will send values to Supermodel that fall within the range -32768 to +32767,
with 0 representing the central or 'off' position. However, in some cases an
axis may behave differently. This has been observed with certain steering
wheels that have their pedals configured in a 'split axis' mode. The pedals
invert their range so that they send -32768 when released and +32767 when fully
depressed. In order for Supermodel to be able to handle such cases the
minimum, off, and maximum values of the axis can be specified with these three
options. The default values are MinVal -32768, OffVal 0, and MaxVal 32767 but
with the pedal example just given, they would need to be set to MinVal 32767,
OffVal 32767, and MaxVal -32768.
In most cases it will be unecessary to alter the DeadZone, MinVal, OffVal, and
MaxVal options by hand as calibrating a joystick axis from within the input
configuration screens of Supermodel will set them automatically. Only the
sensitivity option is not configured in this way.
Additional Options:
InputAutoTrigger, InputAutoTrigger2: When playing light gun games such as 'The
Lost World', the gun must be pointed off-screen and then fired in order to
reload. With a mouse and the default mappings, this requires clicking both the
right and left mouse buttons. In order to be able to reload the gun with just
a single click of the right mouse button, enable these options for players 1
and 2 by setting them to 1. By default they are disabled (value 0).
Enabling these options is also recommended when playing with PC light guns as
these often map the action "point off screen and press trigger" to a single
right mouse button click. Supermodel has been tested successfully with
UltiMarc's AimTrak light-guns. In order to use dual PC light-guns for two
player games, the Raw Input system must be selected with the command line
option '-input-system=rawinput' and the input mappings configured for each gun.
