Quick Code:
// Given that you have 2 movieclips named "marker01" & "marker02" var dist = Math.sqrt((marker01.y-marker02.y)*(marker01.y-marker02.y) + (marker01.x-marker02.x)*(marker01.x-marker02.x));
Hi All, A little bit of a maths update, i have some code that will allow you to figure out the distance between two coords or movieclips. Woo!

Peace Out

This is a very common approach to coordinate distances (and of course works with any x/y value, not just movieclips). I have always been concerned about the use of the square root though – due to them being traditionally very expensive calls to make. Modern CPUs of course optimise around them, but as we know not all Flash games are run on the latest Core i7 boxes

Thanks for your comment. Yeah i’m still experimenting with faster, less resource hungry, ways to accomplish these calcs. I think there’s another approach that uses the Point class (though i’ve heard its worse). Btw nice blog, i think i’ll give it a read
