Is there a way to get a float value to represents the distance between SimpleVectors

Thanks

A method like this should work:

public float distanceBetweenVectors( SimpleVector a, SimpleVector b )
{
    return (float) Math.sqrt( (a.x-b.x)*(a.x-b.x) + (a.y-b.y)*(a.y-b.y) + (a.z-b.z)*(a.z-b.z) );
}

Another way to do it:

Code Select


s1.calcSub(s2).length();

Maybe i should add that method to SimpleVector...

While you're at it, why not a calculateAngle(SimpleVector origin, SimpleVector p1, SimpleVector p2)?
