Method Detail

round

public static int round(float d)

Ends up being a bit faster than Math.round(float). This merely rounds its argument to the nearest int, where x.5 rounds up to x+1.

distance

public static float distance(float aX,
                             float aY,
                             float bX,
                             float bY)

distance

public static float distance(int aX,
                             int aY,
                             int bX,
                             int bY)
