stock Float:GetDistanceBetweenPoints(Float:x,Float:y,Float:z,Float:x2,Float:y2,Float:z2)
{
  new Float:distance[3];
  distance[0] = x - x2;
  distance[0] *= distance[0];
  distance[1] = y - y2;
  distance[1] *= distance[1];
  distance[2] = z - z2;
  distance[2] *= distance[2];
  distance[0] += distance[1] + distance[2];
  return floatsqroot(distance[0]); 
}

The code above would have worked equally as well and you would have been able to retain the stock initializer.
