Force Feedback bug

[NaN]

It is the algorithmic implementation of a low pass filter(to smooth the value):

for i from 1 to n
y[i] :=a * x[i] + (1 - a) * y[i-1]

with a = 10/11.

It would be more obvious with:

Code:

    float new_feedback = 0
    for (int i = 0; i < repeats; ++i)
    {
        ...
        new_feedback += 0.5 * (tire[FRONT_LEFT].GetFeedback() + tire[FRONT_RIGHT].GetFeedback());
    }
    new_feedback /= repeats;                            // average of internal solver loop aka new_feedback
    float a = repeats / (repeats + 1)                    // weight
    feedback = a * new_feedback + (1 - a) * feedback;    // low pass
