Question

JavaScript => public var centroid: Vector2;
C# => public Vector2 centroid;

Description 描述

The centroid of the primitive used to perform the cast.

原始图形的重心。

When the RaycastHit2D is returned from line or ray casting, the centroid is identical to the return point property however when using cast methods that use a geometry shape (as opposed to a simple point) such as circle or box casting, the centroid is the center of the respective shape when it is in contact with the returned point.

当射线或线投射返回RaycastHit2D时，重心等同于返回point属性， 当使用如圆或盒投射方法时（而不是简单的点），当它与接触点重叠时，重心是各自形状的中心。

The centroid is useful in determining the position the cast shape should be for it to collider at the contact point. Note that the point takes into account any rotation specified for the shape when it was cast.

centroid 用来确定投射形状接触点处的碰撞器的重心位置。需要注意的是该点考虑了被投射形状指定的任何旋转。
