@creenv/rectangle

A simpel Rectangle class, usually designed to be used as a Boudingt rectangle, but can fit other purposes including rectangles. It can be used with points of n-dimensions, as long as those points are instances of @creenv/Vector or of @creenv/Vector children (such as @creenv/Vector2, @creenv/Vector3, all available in the @creenv/vector package);

How to use

import Vector from '@creenv/vector';
import Rectangle from '@creenv/rectangle';

// top left point
let p1 = new Vector(1.5,1.5),
    p2 = new Vector(3,3);

let rect = new Rectangle(p1, p2);

rect.topleft; // = p1
rect.bottomright; // = p2

rect.contains(new Vector(2,2)); // true
rect.contain(new Vector(-4,2)); // false
rect.contain(p1); // true

Full doc

Following is a full list of availaible methods via the Rectangle class.

---

constructor (pointA: Vector, pointB: Vector)

The 2 points from opposite corners of the rectangle. It is used to describe a rectangle. It is not required that pointA describes the TOP-LEFT point and pointB the BOTTOM-RIGHT one, but it is advised.

Name	Type	Def
pointA	Vector	The top-left point of the rectangle
pointB	Vector	The bottom-right point of the rectangle

---

class members

Javascript does not allow class members to be private, by definition they all are public. However, the members tagged as private should not be modified for reasons inherant to Rectangle class behavior.

Name	Type	Accessibility	Def
.topleft	Vector	private	pointA from the constructor first argument
*.bottomright	Vector	private	pointB from the constructor second argument
.size	Array.	private	a n-dimensions array, where n is the number of dimensions of pointA dimensions

---

.contains (point: Vector)

Returns true if point is contained within the rectangle and false if it's not. It is required for such a test that point dimensions matches the number of dimensions of the rectangle.

| Name | Type | Def | |---|---|---|---| point | Vector | point with the same number of dimensions as pointA and pointB, that needs to be tested

See example from part 1 for more informations on this function's usage.
