[starlogo-users] Smell Radius

[Daniel Wendel]

Hi John,

I think I uncovered the source of the long-distance smells - it turns out
that the radius you supply is only part of the smell function.  The other
part is the bounding cylinder radius of the objects being smelled.  So, the
agents whose centers are 12 steps away are actually within 10 steps if you
count from the tip of your nose to the tips of their tails.

What do you think about this?  Other users, feel free to chime in!  Should
smell only smell things whose xcor and ycor are within the radius, or should
it smell things which have any part of their shape inside the smelling
radius?

Thanks,
--Daniel
