Syntax

[Serializable]
public struct BezierCurveCubic

Constructors

BezierCurveCubic(Vector2, Vector2, Vector2, Vector2)

Initializes a new instance of the BezierCurveCubic struct.

Declaration

public BezierCurveCubic(Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint)

Parameters

Type	Name	Description
Vector2	startAnchor	The start anchor point.
Vector2	endAnchor	The end anchor point.
Vector2	firstControlPoint	The first control point.
Vector2	secondControlPoint	The second control point.

BezierCurveCubic(float, Vector2, Vector2, Vector2, Vector2)

Initializes a new instance of the BezierCurveCubic struct.

Declaration

public BezierCurveCubic(float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint)

Parameters

Type	Name	Description
float	parallel	The parallel value.
Vector2	startAnchor	The start anchor point.
Vector2	endAnchor	The end anchor point.
Vector2	firstControlPoint	The first control point.
Vector2	secondControlPoint	The second control point.

Fields

EndAnchor

End anchor point.

Declaration

public Vector2 EndAnchor

Field Value

Type	Description
Vector2

FirstControlPoint

First control point, controls the direction of the curve start.

Declaration

public Vector2 FirstControlPoint

Field Value

Type	Description
Vector2

Parallel

Gets or sets the parallel value.

Declaration

public float Parallel

Field Value

Type	Description
float

Remarks

This value defines whether the curve should be calculated as a parallel curve to the original bezier curve. A value of 0.0f represents the original curve, 5.0f i.e. stands for a curve that has always a distance of 5.f to the orignal curve at any point.

SecondControlPoint

Second control point, controls the direction of the curve end.

Declaration

public Vector2 SecondControlPoint

Field Value

Type	Description
Vector2

StartAnchor

Start anchor point.

Declaration

public Vector2 StartAnchor

Field Value

Type	Description
Vector2

Methods

CalculateLength(float)

Calculates the length of this bezier curve.

Declaration

[Pure]
public float CalculateLength(float precision)

Parameters

Type	Name	Description
float	precision	The precision.

Returns

Type	Description
float	Length of the curve.

Remarks

The precision gets better when the precision value gets smaller.

CalculatePoint(float)

Calculates the point with the specified t.

Declaration

[Pure]
public Vector2 CalculatePoint(float t)

Parameters

Type	Name	Description
float	t	The t value, between 0.0f and 1.0f.

Returns

Type	Description
Vector2	Resulting point.
