<B>Description</B><p>
<p>
vD is set to the distance between objects oA and oB. The formula used for calculating the distance is abs(x1-x2) + abs(y1-y2) where x1,y1 and x2,y2 are the co-ordinates of the center of the baselines 
of oA and oB. 
<p>
If one or more of the objects is not on screen, the distance is 255.<p>
