Example #1: Sample Usage

DistanceBetweenPoints(Point(0, 0), Point(1, 1))
// Sqrt(2) ~= 1.41421356
DistanceBetweenPoints(Point(0, 0), Point(0, 10))
// 10

Example #2: PointXY

fixed PointX(point p) {
  point ref = Point(0, 0);

  return cos(DegToRad(AngleBetweenPoints(ref, p)))
    * DistanceBetweenPoints(ref, p);
}

fixed PointY(point p) {
  point ref = Point(0, 0);

  return sin(DegToRad(AngleBetweenPoints(ref, p)))
    * DistanceBetweenPoints(ref, p);
}
// Note: It requires cos and sin.

Example #3: IsPlayerWatching

// Tell if the player camera can see the unit
bool IsPlayerWatching(int player, unit u) {
  point cameraPos = CameraGetTarget(player);
  point unitPos = UnitGetPosition(u);

  return DistanceBetweenPoints(cameraPos, unitPos) < 20;
}
