Gaussian rv for next direction value.
void DoDispose() override
Destructor implementation.
Ptr< NormalRandomVariable > m_normalPitch
Gaussian rv for next pitch.
void Start()
Initialize the model and calculate new velocity, direction, and pitch.
void DoWalk(Time timeLeft)
Perform a walk operation.
double m_meanVelocity
current mean velocity
double m_meanDirection
