distanceToXZ

public static float distanceToXZ(Point p1,
                                 Point p2)

returns distance from p1 to p2 on the XZ plane

distanceToSquaredXZ

public static float distanceToSquaredXZ(Point p1,
                                        Point p2)

returns the square of the distance from p1 to p2 on the XZ plane. More efficient than distanceTo as it doesn't use squareroot.

distanceTo

public static float distanceTo(Point p1,
                               Point p2)

returns distance from p1 to p2

distanceToSquared

public static float distanceToSquared(Point p1,
                                      Point p2)

returns the square of the distance from p1 to p2. More efficient than distanceTo as it doesn't use squareroot.
