Polygon

Body → Polygon

A polygon used to detect collisions

Constructor Summary

Public Constructor
public	constructor(x: Number, y: Number, points: Array<Number[]>, angle: Number, scale_x: Number, scale_y: Number, padding: Number)

Public Members
public	angle: Number The angle of the body in radians
public	scale_x: Number The scale of the body along the X axis
public	scale_y: Number The scale of the body along the Y axis

Public Methods
public	draw(context: CanvasRenderingContext2D) Draws the polygon to a CanvasRenderingContext2D's current path
public	setPoints(new_points: Array<Number[]>) Sets the points making up the polygon.

From class Body
public static	createResult() Creates a Result used to collect the detailed results of a collision test
public	padding: Number The amount to pad the bounding volume when testing for potential collisions
public	x: Number The X coordinate of the body
public	y: Number The Y coordinate of the body
public	collides(target: Circle \| Polygon \| Point, result: Result, aabb: Boolean): Boolean Determines if the body is colliding with another body
public	createResult() Creates a Result used to collect the detailed results of a collision test
public	potentials(): Array<Body> Returns a list of potential collisions
public	remove() Removes the body from its current collision system

The angle of the body in radians

The scale of the body along the X axis

The scale of the body along the Y axis

Draws the polygon to a CanvasRenderingContext2D's current path

Name	Type	Attribute	Description
context	CanvasRenderingContext2D		The context to add the shape to

Sets the points making up the polygon. It's important to use this function when changing the polygon's shape to ensure internal data is also updated.

Name	Type	Attribute	Description
new_points	Array<Number[]>		An array of coordinate pairs making up the polygon - [[x1, y1], [x2, y2], ...]
