Source - geom/Polygon.js, line 29

closed :boolean

Is the Polygon closed or not?

Source - geom/Polygon.js, line 45

flattened :boolean

Has this Polygon been flattened by a call to Polygon.flatten ?

Source - geom/Polygon.js, line 50

points :Array.<Phaser.Point>

This method is deprecated and should not be used. It may be removed in the future.

Sets and modifies the points of this polygon.

See setTo for the different kinds of arrays formats that can be assigned. The array of vertex points.

Type:

• Array.<Phaser.Point>

Deprecated:

• Use `setTo`.

type :number

The base object type.

Methods

clone(output) → {Phaser.Polygon}

Creates a copy of the given Polygon. This is a deep clone, the resulting copy contains new Phaser.Point objects

Parameters:

Name	Type	Argument	Default	Description
output	Phaser.Polygon	<optional>	(new Polygon)	The polygon to update. If not specified a new polygon will be created.

Returns:

Phaser.Polygon -

The cloned (output) polygon object.

Source - geom/Polygon.js, line 109

contains(x, y) → {boolean}

Checks whether the x and y coordinates are contained within this polygon.

Parameters:

Name	Type	Description
x	number	The X value of the coordinate to test.
y	number	The Y value of the coordinate to test.

Returns:

boolean -

True if the coordinates are within this polygon, otherwise false.

Source - geom/Polygon.js, line 134

flatten() → {Phaser.Polygon}

Flattens this Polygon so the points are a sequence of numbers. Any Point objects found are removed and replaced with two numbers. Also sets the Polygon.flattened property to true.

Returns:

Phaser.Polygon -

This Polygon object

Source - geom/Polygon.js, line 91

setTo(points) → {Phaser.Polygon}

Sets this Polygon to the given points.

The points can be set from a variety of formats:

• An array of Point objects: [new Phaser.Point(x1, y1), ...]
• An array of objects with public x/y properties: [obj1, obj2, ...]
• An array of paired numbers that represent point coordinates: [x1,y1, x2,y2, ...]
• An array of arrays with two elements representing x/y coordinates: [[x1, y1], [x2, y2], ...]
• As separate Point arguments: setTo(new Phaser.Point(x1, y1), ...)
• As separate objects with public x/y properties arguments: setTo(obj1, obj2, ...)
• As separate arguments representing point coordinates: setTo(x1,y1, x2,y2, ...)

setTo may also be called without any arguments to remove all points.

Parameters:

Name	Type	Description
points	Array.<Phaser.Point> | Array.<number> | Phaser.Point | number	The points to set.

Returns:

Phaser.Polygon -

This Polygon object

Source - geom/Polygon.js, line 186

toNumberArray(output) → {array}

Export the points as an array of flat numbers, following the sequence [ x,y, x,y, x,y ]

Parameters:

Name	Type	Argument	Description
output	array	<optional>	The array to append the points to. If not specified a new array will be created.

Returns:

array -

The flattened array.
