Question

JavaScript => AddForceAtPosition(force: Vector2, position: Vector2, mode: ForceMode2D = ForceMode2D.Force): void;
C# => void AddForceAtPosition(Vector2 force, Vector2 position, ForceMode2D mode = ForceMode2D.Force);

Parameters 参数

force	Components of the force in the X and Y axes. 在X和Y轴力的组件。
position	Position in world space to apply the force. 在世界空间坐标应用力的位置。
mode	The method used to apply the specified force. 该方法用来应用指定的力。

Description 描述

Apply a force at a given position in space.

在给定位置添加力。

The AddForce function applies a force that acts straight through the rigidbody's centre of mass and so produces only positional movement and no rotation. AddForceAtPosition can apply the force at any position in world space and will typically also apply a torque to the object which will set it rotating. Note that for the purposes of this function, the rigidbody is just a coordinate space of infinite size, so there is no reason why the force needs to be applied within the confines of the object's graphic or colliders.

AddForce函数添加力实际上是应用到刚体的质心，所以只能产生位置移动并不能旋转。AddForceAtPosition可以应用于世界空间的任意位置,通常应用力矩到对象，该函数能使对象旋转。请注意，这个函数的用途，刚体的坐标空间是无限大小，因此没有理由力需应用在对象图形或刚体内部。
