Methods

<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.

Returns:

Phaser.Point -

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

Source - geom/Line.js, line 415

<static> intersectsPoints(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.

Returns:

Phaser.Point -

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

Source - geom/Line.js, line 363

clone(output) → {Phaser.Line}

Returns a new Line object with the same values for the start and end properties as this Line object.

Parameters:

Name	Type	Description
output	Phaser.Line	Optional Line object. If given the values will be set into the object, otherwise a brand new Line object will be created and returned.

Returns:

Phaser.Line -

The cloned Line object.

Source - geom/Line.js, line 184

coordinatesOnLine(stepRate, results) → {array}

Using Bresenham's line algorithm this will return an array of all coordinates on this line. The start and end points are rounded before this runs as the algorithm works on integers.

Parameters:

Name	Type	Argument	Default	Description
stepRate	number	<optional>	1	How many steps will we return? 1 = every coordinate on the line, 2 = every other coordinate, etc.
results	array	<optional>		The array to store the results in. If not provided a new one will be generated.

Returns:

array -

An array of coordinates.

Source - geom/Line.js, line 126

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>	false	If true it will use startSprite.center.x, if false startSprite.x. Note that Sprites don't have a center property by default, so only enable if you've over-ridden your Sprite with a custom class.

Returns:

Phaser.Line -

This line object

Source - geom/Line.js, line 56

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.

Returns:

Phaser.Point -

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

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

Returns:

boolean -

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

Source - geom/Line.js, line 95

pointOnSegment(x, y) → {boolean}

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

Parameters:

Name	Type	Description
x	number	The line to check against this one.
y	number	The line to check against this one.

Returns:

boolean -

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

setTo(x1, y1, x2, y2) → {Phaser.Line}

Sets the components of the Line to the specified values.

Parameters:

Name	Type	Argument	Default	Description
x1	number	<optional>	0	The x coordinate of the start of the line.
y1	number	<optional>	0	The y coordinate of the start of the line.
x2	number	<optional>	0	The x coordinate of the end of the line.
y2	number	<optional>	0	The y coordinate of the end of the line.

Returns:

Phaser.Line -

This line object
