Méthode Description
BezierCurveCubic ( Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )

Constructs a new BezierCurveCubic.
BezierCurveCubic ( float parallel, Vector2 startAnchor, Vector2 endAnchor, Vector2 firstControlPoint, Vector2 secondControlPoint )

Constructs a new BezierCurveCubic.
CalculateLength ( float precision ) : float

Calculates the length of this bezier curve.

The precision gets better when the precision value gets smaller.

CalculatePoint ( float t ) : Vector2

Calculates the point with the specified t.

Résultat Vector2

Property Details

EndAnchor public_oe property

End anchor point.
public Vector2 EndAnchor
Résultat Vector2

FirstControlPoint public_oe property

First control point, controls the direction of the curve start.
public Vector2 FirstControlPoint
Résultat Vector2

Parallel public_oe property

Gets or sets the parallel value.
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.
public float Parallel
Résultat float

SecondControlPoint public_oe property

Second control point, controls the direction of the curve end.
public Vector2 SecondControlPoint
Résultat Vector2

StartAnchor public_oe property

Start anchor point.
public Vector2 StartAnchor
