ControllerColliderHit.normal

설명

The normal of the surface we collided with in world space.

using UnityEngine;

public class Example : MonoBehaviour
{
    void OnControllerColliderHit(ControllerColliderHit hit)
    {
        // print the impact point's normal
        Debug.Log("Normal vector we collided at: " + hit.normal);
    }
}

Note: When the CharacterController is colliding with an edge or a corner rather than a flat surface, the reported normal may be different when colliding with BoxColliders than when colliding with MeshColliders. This is due to a limitation in how PhysX handles Capsule/BoxCollider collisions.
