G920 on PS4

[belun]

In order to use the XBox/PC wheel on the PS4, you need the plugin MaxAimDI in GTuner (because it accepts DirectInput from the PC; the wheel needs to be properly installed on the PC, of course).

I have attached the layout : g920_on_ps4.gpc
It is quite basic (DirectInput mapped to PS4 controller inputs):

• - Wheel steering: Ix -> PS4_LX
• - Gas pedal: Iy -> PS4_R2
• - Brake pedal: IRz -> PS4_L2
• - Clutch pedal: Slider1 -> PS4_RY (right controller stick, down) ; needs to be mapped in-game to R3
• - Left paddle: Button6 -> PS4_L1 (needs to be mapped in-game to L1)
• - Right paddle: Button5 -> PS4_R1 (needs to be mapped in-game to R1)
• - other buttons

The interesting part is the script : wheel max degress.gpc
The purpose of this is to multiply your input (the degrees of rotation) of the wheel to be able to use a lower than max (900 on the G920) configuration (I like to use my wheel at max 200, like an F1 wheel).
Setup : this script has to be loaded from the plugin MaxAimDI (Layout Options > Load GPC Script)

PS: hope to soon write an addition to this script to enable the H-shifter (from DIrectInput buttons to the L1 / R1 on the PS4 controller)

Code: Select all


define STEERING_WHEEL = PS4_LX;

define MAX_ROTATION_200 = 20;
// value read using the Device Monitor from plugin MaxAimDI

define CONTROLLER_STICK_MAX = 100;

int STEERING_WHEEL_MULTIPLIER;

int steering_wheel;
int direction;
main {
    wheel_max_rotation(MAX_ROTATION_200);
}

function wheel_max_rotation(maximum_value) {
    STEERING_WHEEL_MULTIPLIER = CONTROLLER_STICK_MAX / maximum_value;
   
    steering_wheel = get_val(STEERING_WHEEL);
    if(steering_wheel) {
        set_val(STEERING_WHEEL, max(steering_wheel * STEERING_WHEEL_MULTIPLIER, CONTROLLER_STICK_MAX));
    }
}

function max(current_value, maximum_value) {
    direction = abs(current_value) / current_value;
    if(abs(current_value) > maximum_value) {
        return maximum_value * direction;
    } else {
        return current_value;
    }
}
