OsmiaForageMaskDetailed()

OsmiaForageMaskDetailed::OsmiaForageMaskDetailed	(	int	a_step,
		int	a_maxdistance
	)

This is a more detailed forage mask, the idea being that we start to work from the centre out reading the values under m_mask. m_mask just holds offsets to the centre. The mask works as spokes in 8 directions each step distance apart up to the maxdistance. This allows weighting towards the current location.

{
    m_step = a_step;
    m_maxdistance = a_maxdistance;
    int rings = m_maxdistance / m_step;
    m_mask.push_back(APoint(0, 0));
    for (int r = 1; r <= rings; r++)
    {
        for (int d = 0; d < 8; d++)
        {
            m_mask.push_back(APoint(r * g_vector_x[d], r * g_vector_y[d]));
        }
    }
}

Member Data Documentation

m_mask

vector<APoint> OsmiaForageMaskDetailed::m_mask

Holds 20 distances and 8 directions with offsets to x,y.

This is a way to speed up searches from a centre point. The predefined mask can be iterated through without having to calculate offsets. It could also be modified to alter distances between locations if needed by altering the step size.
