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

Description 描述

The normal vector of the surface hit by the ray.

射线碰到表面的法线向量。

The normal vector of a surface is the vector that points outward perpenidularly at a given point on that surface. This vector can be useful in raycasting as a way to determine reflections or ricochets from projectiles or to align a character so that it stands upright on the surface.

表面的法线向量是表面接触点的向外垂直的点的向量。这个向量用于确定反射或炮弹弹射或对齐角色直立在表面上。

Note that if a hit occurs starting inside a collider then the collision normal will be simply the opposite direction of the line/ray query.

注意，如果碰撞发生在碰撞器内，那么碰撞法线将简单的是射线的反方向。
