Methods

<static> intersects(a, b, e, f, asSegment, result) → {Phaser.Point}

Checks for intersection between two lines as defined by the given start and end points. If asSegment is true it will check for line segment intersection. If asSegment is false it will check for line intersection. Returns the intersection segment of AB and EF as a Point, or null if there is no intersection. Adapted from code by Keith Hair

Parameters:

Name	Type	Argument	Default	Description
`a`	Phaser.Point			The start of the first Line to be checked.
`b`	Phaser.Point			The end of the first line to be checked.
`e`	Phaser.Point			The start of the second Line to be checked.
`f`	Phaser.Point			The end of the second line to be checked.
`asSegment`	boolean	<optional>	true	If true it will check for segment intersection, otherwise full line intersection.
`result`	Phaser.Point	<optional>		A Point object to store the result in, if not given a new one will be created.

Source:

geom/Line.js, line 183

Returns:

The intersection segment of the two lines as a Point, or null if there is no intersection.

Type: Phaser.Point

<static> intersects(a, b, asSegment, result) → {Phaser.Point}

Checks for intersection between two lines. If asSegment is true it will check for segment intersection. If asSegment is false it will check for line intersection. Returns the intersection segment of AB and EF as a Point, or null if there is no intersection. Adapted from code by Keith Hair

Parameters:

Name	Type	Argument	Default	Description
`a`	Phaser.Line			The first Line to be checked.
`b`	Phaser.Line			The second Line to be checked.
`asSegment`	boolean	<optional>	true	If true it will check for segment intersection, otherwise full line intersection.
`result`	Phaser.Point	<optional>		A Point object to store the result in, if not given a new one will be created.

Source:

geom/Line.js, line 246

Returns:

The intersection segment of the two lines as a Point, or null if there is no intersection.

Type: Phaser.Point

fromSprite(startSprite, endSprite, useCenter) → {Phaser.Line}

Sets the line to match the x/y coordinates of the two given sprites. Can optionally be calculated from their center coordinates.

Parameters:

Name	Type	Argument	Default	Description
`startSprite`	Phaser.Sprite			The coordinates of this Sprite will be set to the Line.start point.
`endSprite`	Phaser.Sprite			The coordinates of this Sprite will be set to the Line.start point.
`useCenter`	boolean	<optional>	true	If true it will use startSprite.center.x, if false startSprite.x.

Source:

geom/Line.js, line 57

Returns:

This line object

Type: Phaser.Line

intersects(line, asSegment, result) → {Phaser.Point}

Checks for intersection between this line and another Line. If asSegment is true it will check for segment intersection. If asSegment is false it will check for line intersection. Returns the intersection segment of AB and EF as a Point, or null if there is no intersection.

Parameters:

Name	Type	Argument	Default	Description
`line`	Phaser.Line			The line to check against this one.
`asSegment`	boolean	<optional>	true	If true it will check for segment intersection, otherwise full line intersection.
`result`	Phaser.Point	<optional>		A Point object to store the result in, if not given a new one will be created.

Source:

geom/Line.js, line 81

Returns:

The intersection segment of the two lines as a Point, or null if there is no intersection.

Type: Phaser.Point

pointOnLine(x, y) → {boolean}

Tests if the given coordinates fall on this line. See pointOnSegment to test against just the line segment.

Parameters:

Name	Type	Description

`y`	number	The line to check against this one.

Source:

geom/Line.js, line 98

Returns:

True if the point is on the line, false if not.

Type: boolean

pointOnSegment(x, y) → {boolean}
