EllipseCurve

Constructor

new EllipseCurve( aX : number, aY : number, xRadius : number, yRadius : number, aStartAngle : number, aEndAngle : number, aClockwise : boolean, aRotation : number )

Constructs a new ellipse curve.

| aX |

The X center of the ellipse.

Default is 0.

| | aY |

The Y center of the ellipse.

Default is 0.

| | xRadius |

The radius of the ellipse in the x direction.

Default is 1.

| | yRadius |

The radius of the ellipse in the y direction.

Default is 1.

| | aStartAngle |

The start angle of the curve in radians starting from the positive X axis.

Default is 0.

| | aEndAngle |

The end angle of the curve in radians starting from the positive X axis.

Default is Math.PI*2.

| | aClockwise |

Whether the ellipse is drawn clockwise or not.

Default is false.

| | aRotation |

The rotation angle of the ellipse in radians, counterclockwise from the positive X axis.

Default is 0.

|

Properties

.aClockwise : boolean

Whether the ellipse is drawn clockwise or not.

Default is false.

.aEndAngle : number

The end angle of the curve in radians starting from the positive X axis.

Default is Math.PI*2.

.aRotation : number

The rotation angle of the ellipse in radians, counterclockwise from the positive X axis.

Default is 0.

.aStartAngle : number

The start angle of the curve in radians starting from the positive X axis.

Default is 0.

.aX : number

The X center of the ellipse.

Default is 0.

.aY : number

The Y center of the ellipse.

Default is 0.

.isEllipseCurve : boolean (readonly)

This flag can be used for type testing.

Default is true.

.xRadius : number

The radius of the ellipse in the x direction. Setting the this value equal to the EllipseCurve#yRadius will result in a circle.

Default is 1.

.yRadius : number

The radius of the ellipse in the y direction. Setting the this value equal to the EllipseCurve#xRadius will result in a circle.

Default is 1.

Methods

.getPoint( t : number, optionalTarget : Vector2 ) : Vector2

Returns a point on the curve.

| t |

A interpolation factor representing a position on the curve. Must be in the range [0,1].

| | optionalTarget |

The optional target vector the result is written to.

|

Overrides: Curve#getPoint Returns: The position on the curve.
