描述

|
----
|
|
|
|
2D 射线形状，旨在用于物理。通常用来为 :ref:`CollisionShape2D<class_CollisionShape2D>` 提供形状。\ **SeparationRayShape2D** 与某个对象发生碰撞时，会尝试将其端点移动至碰撞点，来将自己与该对象分离。例如，角色旁边的 **SeparationRayShape2D** 可以让角色在接触楼梯时立即向上移动。

如果为 ``false``\ （默认值），则形状始终分离，并返回一条沿其自身方向的法线。
|
|
|
|
如果为 ``true``\ ，则该形状可以返回正确的法线，并在任何方向上分离，允许在斜坡上滑动。
