setSteeringValue method
Set the steering value of a wheel. @todo check coordinateSystem
Implementation
void setSteeringValue(double value, int wheelIndex) {
// Set angle of the hinge axis
final axis = wheelAxes[wheelIndex];
final c = math.cos(value);
final s = math.sin(value);
final x = axis.x;
final z = axis.z;
constraints[wheelIndex].axisA.set(-c * x + s * z, 0, s * x + c * z);
}
