quick hacky solution - apols, but on the way out :p
you could divide up the screen into rects and have a list of points
within each division which will cut down your search.
e.g if inside(the mouseloc, rect1) then
check distance using pythag between your mouseloc and the points in
your sublist inside that rect.
hackie voila.
hth, off to the pub :)

Hi Guys,
I'm hoping someone can help me out with a quick pointer, I've got a
tight deadline and my minds gone a bit blank.
I have a list of points....
[point(112,456), point(12,485), ...] list goes to about 50
These are actually co-ordinates of certain pixels on my stage.
I need to find the closest one (radius) to any given point - i.e. the
mouseLoc - it needs to be fairly efficient as I will need to do it
every
frame \ couple of frames.
Can someone point me in the right direction please.
Many thanks
Tim
