Описание свойств

ControlPoint публичное свойство

Control point, controls the direction of both endings of the curve.

public Vector2 ControlPoint
Результат	Vector2

EndAnchor публичное свойство

End anchor point.

public Vector2 EndAnchor
Результат	Vector2

Parallel публичное свойство

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
Результат	float

StartAnchor публичное свойство

Start anchor point.

public Vector2 StartAnchor
Результат	Vector2
