How to use
- Installation
npm install pointscape- Usage
import pointscape from "pointscape";Examples
import {
distance,
triangle,
center,
inRange,
chunk,
randomBoolean } from "pointscape";
const distanceBetweenPoints = distance({x: 0, y: 0}, {x: 10, y: 10});
console.log(distanceBetweenPoints);
// output: 14.142135623730951
const pointsForTriangle = triangle({x: 0, y: 0}, 10);
console.log(pointsForTriangle);
// output: [ { x: 0, y: 0 }, { x: -10, y: 0 }, { x: -5, y: 8.660254037844386 } ]
const centralPoint = center(
[{x:0, y: 0}, {x:0, y:10}, {x:10, y:10}, {x:10, y:0}]
);
console.log(centralPoint);
// output: { x: 5, y: 5 }
const isInTheRange = inRange(1, 0, 10);
console.log(isInTheRange);
// output: true
const chunks = chunk([1, 1, 1, 1], 2);
console.log(chunks);
// output: [[1, 1], [1, 1]]
const randomBool = randomBoolean();
console.log(randomBool)
// output: true or false

Actions with points in XY coordinate system
distance(point1, point2)
Returns the distance beetween two points, each point is an object with x and y properties.
area(points)
Returns the area enclosed by the given points. Takes an array of points as argument, where each point is an object with x and y properties.
collision(point1, point2, collisionDistance, [callback])
Returns a boolean indicating if the two points are closer than the given distance.
collisionInArray(point, radius, points, [callback])
Returns the point that is closer than the radius to the given point, or false if there's no collision.
positionInCircle(point, radius, angleInRadians)
Returns the x and y coordinates for the current point in the circle, given its center point, radius, and angle.
angle(point1, point2)
Returns the angle formed by the connection of two points.
middle(point1, point2)
Returns the midpoint between two points.
nearest(point, points)
Returns the nearest point to the given point from the array.
perimeter(points)
Returns the perimeter of the figure formed by the given points.
pointWithoutCollision(minX, maxX, minY, maxY, distance, points)
Returns a point that doesn't collide with any of the given points within the specified distance, if such a point exists, otherwise returns false.
randomPoint([xMin], [xMax], [yMin], [yMax])
Returns a random point within the given dimensions, if provided, otherwise in 100 units on both axes.
randomPointInDistance(point, distance)
Returns a random point within the given distance from the specified point.
randomPoints(quantity, [xMin], [xMax], [yMin], [yMax], )
Returns a specified quantity of random points within the given dimensions, if dimensions are provided, otherwise in the range of 100.
possibleConnections(pointsCount)
Returns the quantity of possible connections among given quantity of points.
circleArea(radius)
Returns the area of the circle.
center(points)
Returns the center of given points.
farest(point, points)
Returns the farest point to the given point from the array.
rotate(point, points, angleInRadians)
Returns the points rotated around the given point.
sort(points, [coordinate])
Returns sorted array of the points.The coordinate parameter can be "x", "y", or none for sorting both for "x" and "y".
scale(scaleFactorX, scaleFactorY, points)
Returns the scaled points.
inLine([point1, point2, point3])
Returns boolean value indicating whether or not the given coordinates are on line defined by two other points.
cross(line1Start, line1End, line2Start, line2End)
Returns boolean value indicating if two lines each defined by two points intersect.
move(point, xStep, yStep, count)
Returns an array of points representing a moving point over time. The number of elements in the array is equal to "count". Each element contains coordinates of the point.
square(point, size, [direction])
Returns an array of points representing a shape of square.Takes four parameters: starting coordinates (x and y), size of square side, and direction which should be one of the values "left", "right", "up", "down".
rectangle(point, size, [direction])
Returns an array of points representing a shape of rectangle.Takes same parameters as square function.
triangle(point, size, [direction])
Returns an array of points representing a shape of triangle.Takes same parameters as square function.
pentagon(point, size, [direction])
