JavaScript => public var uv3: Vector2[];
C# => public Vector2[] uv3;

Description 描述

The third texture coordinate set of the mesh, if present.

网格的第三套纹理坐标，如果存在的话。

JavaScript:

	// Generate planar uv coordinates for all 4 uv sets
 
	function Start () {
		var mesh : Mesh = GetComponent.<MeshFilter>().mesh;
		var vertices : Vector3[]  = mesh.vertices;
		var uvs : Vector2[] = new Vector2[vertices.Length];
 
		for (var i = 0 ; i < uvs.Length; i++)
			uvs[i] = Vector2 (vertices[i].x, vertices[i].z);
 
		mesh.uv2 = uvs;
		mesh.uv3 = uvs;
		mesh.uv4 = uvs;
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        Mesh mesh = GetComponent<MeshFilter>().mesh;
        Vector3[] vertices = mesh.vertices;
        Vector2[] uvs = new Vector2[vertices.Length];
        int i = 0;
        while (i < uvs.Length) {
            uvs[i] = new Vector2(vertices[i].x, vertices[i].z);
            i++;
        }
        mesh.uv2 = uvs;
        mesh.uv3 = uvs;
        mesh.uv4 = uvs;
    }
}
