説明

接触点の法線

The following example will draw a line to represent every normal from a collision. Each line will be drawn in the Scene view.

using UnityEngine;

public class Example : MonoBehaviour { void OnCollisionEnter(Collision other) { // Print how many points are colliding with this transform Debug.Log("Points colliding: " + other.contacts.Length);

// Print the normal of the first point in the collision. Debug.Log("Normal of the first point: " + other.contacts[0].normal);

// Draw a different colored ray for every normal in the collision foreach (var item in other.contacts) { Debug.DrawRay(item.point, item.normal * 100, Random.ColorHSV(0f, 1f, 1f, 1f, 0.5f, 1f), 10f); } } }
