JavaScript => public var normals: Vector3[];
C# => public Vector3[] normals;

Description 描述

The normals of the mesh.

网格的法线。

If the mesh contains no normals an empty array will be returned.

如果该网格布包含法线，将返回空数组。

JavaScript:

	// Rotate the normals by speed every frame
 
	var speed = 100.0;
 
	function Update () {
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;
		var normals : Vector3[] = mesh.normals;
 
		var rotation : Quaternion = Quaternion.AngleAxis(Time.deltaTime * speed, Vector3.up);
		for (var i = 0; i < normals.Length; i++)
			normals[i] = rotation * normals[i];
 
		mesh.normals = normals;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public float speed = 100.0F;
    void Update() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] normals = mesh.normals;
        Quaternion rotation = Quaternion.AngleAxis(Time.deltaTime * speed, Vector3.up);
        int i = 0;
        while (i < normals.Length) {
            normals[i] = rotation * normals[i];
            i++;
        }
        mesh.normals = normals;
    }
}
