项目中，有时候导入一些资源时候，需要对应创建材质球，如果每次自己动手创建，还是挺麻烦的，下面是如何导入资源时候自动创建材质球。

using UnityEngine;using System.Collections;using System.Collections.Generic;using UnityEditor;using System.IO;public class BuildMaterial : UnityEditor.AssetModificationProcessor{    //生成出的Material的路径    private static string MaterialsPath = "Assets/Resources/Skin/";    // 创建菜单按钮，手工调用创建材质    [MenuItem ("HETools/BuildMaterials")]    static void CreateMateral ()    {        Object[] selectObject = Selection.objects;        List<string> path = new List<string> ();        foreach (Object obj in selectObject) {            path.Add (AssetDatabase.GetAssetPath (obj));        }        foreach (string p in path) {            CreateOneMateral (p);        }        System.GC.Collect ();    }    // 监控assets资源添加，发现指定目录ThemeTile有新增加的texture，就自动生成材质    public static void OnWillCreateAsset (string path)    {        int index = path.LastIndexOf (".");        string file = path.Substring (index);        string[] pathArr = path.Split ('/');        if (pathArr [pathArr.Length - 3] != "ThemeTile")            return;        CreateOneMateral (path);        System.GC.Collect ();    }    // 创建材质球    static void CreateOneMateral (string p)    {        p = p.Replace (".meta", "");        Debug.Log ("CreateOneMateral from path: " + p);        int pos = p.LastIndexOf ('/');        if (pos == -1)            return;        string[] strArr = p.Split ('/');        string themeIDStr = strArr [strArr.Length - 2];        Texture textur = (Texture)AssetDatabase.LoadAssetAtPath (p, typeof(Texture)) as Texture;        string name = strArr [strArr.Length - 1];        int y = name.IndexOf ('.');        name = name.Substring (0, y);        Material mater = new Material (Shader.Find ("Mobile/VertexLit"));        mater.mainTexture = textur;        AssetDatabase.CreateAsset (mater, MaterialsPath + themeIDStr + "/" + name + ".mat");    }}
