Hi Tim,
Just off the top of my head this might get you started (email lingo, watch
for typos)
on getNearestPoint aListOfPoints, aRefPoint
d = the maxInteger
tWhichPoint = 0
repeat with i in aListOfPoints
a = aRefPoint[1] - i[1]
b = aRefPoint[2] - i [2]
c = a*a + b*b
if c < d then
tWhichPoint = aListOfPoints.getOne(i)
end if
end repeat
return tWhichPoint
end
hth,
Rob

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.
