Features #

Pos

• Added vectorLine as a faster Line function (alternative to bresenham):

  vectorLine(Pos(0, 0), Pos(2, 2)); // [Pos(0, 0), Pos(1, 1), Pos(2, 2)]
  

• Added diagonal distance to compliment manhattan and chebyshev distances:

  Pos(0, 0).distanceTo(Pos(3, 4), diagonal); // 5.0
  

• Added <Pos>.inflate, which uses the position as the center of a rectangle and inflates it by the given delta Pos offset:

  Pos(5, 5).inflate(Pos(2, 2)); // Rect.fromLTRB(3, 3, 7, 7)
  

• Added <Pos>.toRect() to convert a position to a rectangle with a size of 1x1:

  Pos(5, 5).toRect(); // Rect.fromLTWH(5, 5, 1, 1)
  

• Added <Pos>.max, <Pos>.min, and <Pos>.clamp to get the maximum, minimum, and clamped position between two positions:

  Pos(5, 5).max(Pos(3, 3)); // Pos(5, 5)
  Pos(5, 5).min(Pos(3, 3)); // Pos(3, 3)
  Pos(5, 5).clamp(Pos(3, 3), Pos(7, 7)); // Pos(5, 5)
  

• Added <Pos>.approximateNormalized, which returns a new position with the

• same direction but a magnitude as close as possible to 1, which is the best

• possible for fixed-point positions:

  Pos(10, 20).approximateNormalized; // Pos(1, 2)
  

• Added <Pos>.dot and <Pos>.cross to calculate the dot and cross products between two positions:

  Pos(1, 2).dot(Pos(3, 4)); // 11
  Pos(1, 2).cross(Pos(3, 4)); // -2
  

• Added missing core operators: ~/, %, ~, <<, >>.

Rect

• Added <Rect>.inflate and <Rect>.deflate, which, given a delta Pos offset inflates or deflates the rectangle by that amount:

  final rect = Rect.fromLTWH(0, 0, 10, 10);
  rect.inflate(Pos(2, 2)); // Rect.fromLTRB(-2, -2, 12, 12)
  rect.deflate(Pos(2, 2)); // Rect.fromLTRB(2, 2, 8, 8)
  

Misc

• Added a new extension on (int, int) to convert a tuple to a Pos:

  (5, 5).toPos(); // Pos(5, 5)
  

• Added approximateSqrt, to calculate the integer square root of a number without rounding:

  approximateSqrt(10); // 3
