Determine If Two Points Are Near

Question

I have the following:

bool AreNear(Point Old, Point Current)
{
    int x1 = Convert.ToInt32(Old.X);
    int x2 = Convert.ToInt32(Current.X);
    int y1 = Con         


        

Answer 1

You can use Math.Abs to get the distance:

public static bool InDistance(Point Old, Point Current, int distance)
{
    int diffX = Math.Abs(Old.X - Current.X);
    int diffY = Math.Abs(Old.Y - Current.Y);
    return diffX <= distance && diffY <= distance;
}

use it:

bool arePointsInDistance = InDistance(new Point(100, 120), new Point(120, 99), 25);
