class in UnityEngine/Inherits from: Effector2D

Applies forces to attract/repulse against a point.

应用力去吸引/击退攻击一个点。

When the source Collider2D is a trigger, the effector will apply forces whenever the target Collider2D overlaps the source. When the source Collider isn't a trigger, the effector will apply forces whenever the target Collider2D is in contact with the source only.

当源2D碰撞器触发，该效应器将会应用力到目标2D碰撞器与源碰撞器重叠部分。当源2D碰撞器不触发时，效应器将会仅应用力到目2D碰撞器接触的部分。

This effector is designed primarily to work with source Collider2D that are set as triggers so that target Collider2D can overlap the defined area.

该效应器设计首要作用于源2D碰撞器，设置作为触发器因此目标2D碰撞器可以与定义区域重叠。
