clone line.js:87

clone() → {Line}

clone this line segment

Returns:
Type	Description
Line	new Line

contains line.js:15

contains(x: number | Vector2d, y: number) → {boolean}

Returns true if the Line contains the given point

if (line.contains(10, 10)) {
  // do something
}
// or
if (line.contains(myVector2d)) {
  // do something
}

Parameters:
Name	Type	Attributes	Description
x	number \| Vector2d		x coordinate or a vector point to check
y	number	<optional>	y coordinate

Returns:
Type	Description
boolean	true if contains

recalc line.js:53

recalc() → {Line}

Computes the calculated collision edges and normals. This must be called if the points array, angle, or offset is modified manually.

Returns:
Type	Description
Line	this instance for objecf chaining
