hi, im feeling embarassed asking such a simple question but it has been a long time since I did maths in college. I'm developing a program, for which I have to calculate the length between 2 objects. I have tried: x1 - x2; y1 - y2; but this results in another set of co-ordinates and I need a single value that gives the distance between these 2 objects. If anybody understands what I'm saying and has the solution it would be a great help. thanx
