@SP: Did that test and got results around 18ms. Very few times above 20ms and very few times below 15ms. I know what you meant though: not accessing variables from an object, but using a point doesn’t seem to have a big influence. I wonder how it would behave with some getter like LEFT from a rectangle object.

private function DistanceTest4()
{
for (var test:int = 1; test <= 1000000; test++)
{
var x1:Number = 100;
var y1:Number = 200;
var x2:Number = 100;
var y2:Number = 200;

var dx:Number = x1 – x2;
var dy:Number = y1 – y2;

var distance:Number = dx * dx + dy * dy;
}
}
