Why does it mean that the target position is in range? Sorry for the long explanation but I hope you guys can help me.

func inRange(position: Point, range: Int, target: Point) -> Bool { let availablePostions = position.surrondingPoints(withRange: range) for point in availablePostions { if (point.x == target.x) && (point.y == target.y) { return true } } return false }

so I understand position is the initial coordinates of the tower, range is just the range between initial position and a target on the map and finally target are the coordinates of the target.

Now for me the first contant created (availablePositions) creates an array of points containing ALL points around the tower at all ranges. So basically all the other points on the map except the initial position. Then the for in loop iterates over all the points in the arrays of points that are created with the availablePositions constant.

Now Pasan says if a point as the same x and y value than the target than the target is in range. For me that is wrong as my understanding of that would just mean that the target is on the map somewhere at ANY range since the points created in availablePositions are at all ranges. What am I missing?

Thank you and sorry for the wall of text....
