Prerequisites

Requires installed version of VJoy 2.1.8. Available here: https://sourceforge.net/projects/vjoystick/files/Beta%202.x/

Configuration

Program can be configured through config.txt file, which have 21 different values, that can be modified through any text editor. For easier tweaking use VjoyMonitor to visualize axis changes.

Sensitivity

The main sensitivity multiplier. Raw data from mouse is multiplied by this value and then added to Vjoy Axis.

E.g. Sensitivity = 6.0

AttackTimeThrottle

Throttle value when pressed. When throttle is pressed, every 2 ms value is added to Vjoy Axis. The greater the steaper slope of attack.

E.g. AttackTimeThrottle = 200

ReleaseTimeThrottle

Throttle value when released. When throttle is released, every 2 ms value is subtracted from Vjoy Axis. The greater the steaper slope of release.

E.g. ReleaseTimeThrottle = 100

AttackTimeBreak

Break value when pressed. When break is pressed, every 2 ms value is added to Vjoy Axis. The greater the steaper slope of attack.

E.g. AttackTimeBreak = 200

ReleaseTimeBreak

Break value when released. When break is released, every 2 ms value is subtracted from Vjoy Axis. The greater the steaper slope of release.

E.g. ReleaseTimeBreak = 100

AttackTimeClutch

Clutch value when pressed. When clutch is pressed, every 2 ms value is added to Vjoy Axis. The greater the steaper slope of attack.

E.g. AttackTimeClutch = 200

ReleaseTimeClutch

Clutch value when released. When clutch is released, every 2 ms value is subtracted from Vjoy Axis. The greater the steaper slope of release.

E.g. ReleaseTimeClutch = 200

ThrottleKey

Key responsible for throttle control. Works only when UseMouse is equal to 0. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. ThrottleKey = 87 for "W"

BreakKey

Key responsible for break control. Works only when UseMouse is equal to 0. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. BreakKey = 69 for "E"

ClutchKey

Key responsible for clutch control. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. ClutchKey = 67 for "C"

GearShiftUpKey

Key responsible for gear shift up. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. GearShiftUpKey = 83 for "D"

GearShiftDownKey

Key responsible for gear shift down. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. GearShiftDownKey = 68 for "S"

HandBrakeKey

Key responsible for handbreak. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. HandBrakeKey = 32 for Space

MouseLockKey

Key responsible for locking mouse in 0,0 coordinates on monitor. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. MouseLockKey = 80 for "P"

MouseCenterKey

Key responsible for centering Steering Vjoy Axis. Key value can be anything from 0 to 165 in ASCII KEYCODES!

E.g. MouseCenterKey = 79 for "0"

UseMouse

Whenever to use mouse buttons as throttle and break. 0 for Disable, 1 for Enable.

E.g. UseMouse = 1

UseCenterReduction

Whenever to reduce mouse sensitivity when closer to center of axis. 0 for Disable, 1 for Enable.

E.g. UseCenterReduction = 1

UseForceFeedback

Whenever to use forcefeedback. 0 for Disable, 1 for Enable.

E.g. UseForceFeedback = 1

UseWheelAsShifter

Whenever to use mouse wheel as a sequential shifter. Mouse wheel up for next gear and mouse wheel down for lower gear. 0 for Disable, 1 for Enable.

E.g. UseWheelAsShifter = 1

AccelerationThrottle

Whenever to add linear acceleration on throttle Vjoy Axis. 0 for Disable, greater then 0 for Enable.

E.g. AccelerationThrottle = 1.01

AccelerationBreak

Whenever to add linear acceleration on break Vjoy Axis. 0 for Disable, greater then 0 for Enable.

E.g. AccelerationBreak = 1.01

AccelerationClutch

Whenever to add linear acceleration on clutch Vjoy Axis. 0 for Disable, greater then 0 for Enable.

E.g. AccelerationBreak = 1.01

CenterMultiplier

How much center reduction to use. Greater then 1 to make center less sensitive while making ends more sensitive. Lesser then 1 to make center more sensitive while making ends less sensitive.

E.g. CenterMultiplier = 1.20

Hat tip to anyone who's code was used

Segmentation fault on FileRead class

The function "newFile" in the FileRead class is accessing a position outside of the "checkArray" length, which may result in accessing a protected memory region (Segmentation fault).

The issue is the maximum value of 'i' is 32 but the checkArray in that case is 23:

// Segmentation fault
for(int i = 0; i < 32; i++){
    if (tmp == checkArray[i]) {
        _resultArray[i] = value;
    }
}

I think a simple fix can be like this:

// fileread.h
// { ... }    Others includes
#include<vector>

class FileRead {
public:
    BOOL newFile(std::string fileName, std::string checkArray[], size_t checkArraySize);

    double result(int number) { 
        if (_resultArray && number < _resultLen)
            return _resultArray[number];
        else
        {
            // Some error handling
        }
    };
private:
    size_t _resultLen = 0;
    double* _resultArray = NULL;
};

Each time you call the 'newFile' function, it will free the old memory if it exists and allocates a new one to store the results.

// fileread.cpp
BOOL FileRead::newFile(std::string fileName, std::string checkArray[], size_t checkArraySize) {
    if (this->_resultArray)
        free(_resultArray); // Free de old allocated memory
    this->_resultLen = Lenght;
    if(!(_resultArray = static_cast<double*>(malloc(sizeof(double) * Lenght)))) // Allocate a new memory ( can be done with 'new(double[size])' )
        return FALSE;
    ZeroMemory(_resultArray, Lenght * sizeof(double));
    std::ifstream file(fileName);
    if (!file.is_open()) 
    {
        printf("Config file not found\n");
        return FALSE;
    }
    // { ... }    Code
    for(int i = 0; i < checkArraySize; i++){
        if (tmp == checkArray[i]) {
            _resultArray[i] = value;
        }
    }
    // { ... }   Code
    file.close();
    return TRUE;
}
