Joystick Curves made easy

[thedude]

This simple function gives a nice curve, slow near the center.
Wonder if anyone had this or something similar? If not, enjoy.

Code: Select all

 
main {
    Curves(PS4_RX);
    Curves(PS4_LX);
}
void Curves (uint8 axis)
{
    fix32 R = pow(abs(get_val(axis)), 2.0) / 100.0;
    if(get_actual(axis) < 00.00 ) R = -R;
    set_val(axis, R);
 
}

Nice, thank you for sharing. If you haven't yet, please also consider publish your script on Gtuner IV Online Resources.

It is published as a function in my recent contribution:

Changed the curve to use multiplication, because the power function takes so much more cpu time.

Code: Select all

 
void Curves (uint8 axis)
{
    // power works and can be used for different curves, but it is slow
    //fix32 R = pow(abs(get_val(axis)), 2.0) / 100.0;
 
    // multiplication is about 18 times faster, great if using power of 2.
    fix32 axisval = get_actual(axis);
    fix32 R = axisval * axisval / 100.0;
    if(axisval < 00.00 ) R = -R;
    set_val(axis, R);    
}

Awesome, thank you.

What's does do this script

[J2Kbr]

It applies an exponential transformation, making the movements near the center position less sensitive and near the edges more sensitive.
