Static methods

`staticpoint_on_cubic_curve(t:Float, ax:Float, ay:Float, bx:Float, by:Float, cx:Float, cy:Float, dx:Float, dy:Float):Vector2`

Gets the point at the defined t (a value between 0.0 to 1.0) from a Cubic Bezier Curve constructed out of points (ax, ay), (bx, by), (cx, cy), and (dx, dy).

`staticpoint_on_quadratic_curve(t:Float, ax:Float, ay:Float, bx:Float, by:Float, cx:Float, cy:Float):Vector2`

Gets the point at the defined t (a value between 0.0 to 1.0) from a Quadratic Bezier Curve constructed out of points (ax, ay), (bx, by), and (cx, cy).

`staticsubdivide_cubic_bezier_curve(ax:Float, ay:Float, bx:Float, by:Float, cx:Float, cy:Float, dx:Float, dy:Float, ?points:Array<Vector2>, options:BezierSubdivisionOptions):Null<Array<Vector2>>`

Constructor

`@:value({ curve_mode : Cubic })new(?control_points:Array<Vector2>, curve_mode:BezierCurve = Cubic)`

Variables

`closed:Bool`

`read onlycontrol_count:Int`

The amount of control points in this Curve.

`@:value(0)read onlycurve_count:Int = 0`

`curve_mode:BezierCurve`

`read onlylength:Float`

`@:value(Subdivisions())line_mode:BezierLineMode = Subdivisions()`

The method used to construct lines from the Curve.

`@:value([])read onlylines:Array<Line> = []`

Cached Array of Lines that represents the current state of the Curve.

`@:value([])read onlypoints:Array<Vector2> = []`

Cached Array of Points that represents the current state of the Curve.

`on_dirty:Bezier ‑> Void`

Methods

`add_control_point(x:Float, y:Float):Void`

`add_curve(x:Float, y:Float):Void`

`dispose():Void`

`inlineget_control_point(index:Int):Null<Vector2>`

`inlineget_control_points():Array<Vector2>`

`inlineget_control_points_in_curve(index:Int):Array<Vector2>`

`@:value({ start_index : -1 })inlineget_point(t:Float, start_index:Int = -1):Null<Vector2>`

Gets the point on the Curve at the defined t.

Parameters:

`t`	A value between 0.0 to 1.0.
`start_index`	Determines the starting control point that will be used to construct the Curve. If set to -1, this will be determined automatically based on `t`.
