Unity3d防止材质贴图丢失解决办法
发表于2017-11-30
使用Unity引擎做开发时，如何防止材质贴图丢失这个问题？可能有些新手开发者还不知道，那下面我们就来看看防止材质贴图丢失解决办法，只需要两步即可。
第1步在project文件管理器中创建Editor文件夹，并在之下创建一个CreateAssetBundle.cs脚本，它可用来打包文件，防止在其他地方重新打开时，缺失材质而需要重新附加各种贴图。
第2步新建Resources文件用于存放各种材质资源，如FBX等模型文件、material等材质文件、各种格式文件如JPEG、PNG等图片文件等等。
如图：
CreateAssetBundle.cs脚本如下，它规定了打包的文件格式以及生成版本号到version.txt文件中，可自定义添加需要的格式。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using System.IO;
public class CreateAssetBundle : Editor
｛
static void FindDependencies(string strPath, List<string> strPathList)
｛
if (strPathList.Contains(strPath))
｛
return;
｝
else
｛
strPathList.Add(strPath);
string[] strArrayDependencies = AssetDatabase.GetDependencies(strPathList[strPathList.Count - 1]);
foreach (var m in strArrayDependencies)
｛
FindDependencies(m, strPathList);
｝
return;
｝
｝
[MenuItem("Custom Editor/Create AssetBunldes Main")]
static void CreateAssetBunldesMain()
｛
WriteVersion();
Caching.CleanCache();
List<string> strPathList = new List<string>();
Object[] SelectedAsset = Selection.GetFiltered(typeof(Object), SelectionMode.DeepAssets);
foreach (var n in SelectedAsset)
｛
Debug.Log(AssetDatabase.GetAssetOrScenePath(n));
FindDependencies(AssetDatabase.GetAssetOrScenePath(n), strPathList);
｝
string targetPath = Application.dataPath + "/StreamingAssets";
if (!Directory.Exists(targetPath))
｛
Directory.CreateDirectory(targetPath);
｝
AssetBundleBuild[] abBuilds = new AssetBundleBuild[6];
List<string> strPrefab = new List<string>();
List<string> strModel = new List<string>();
List<string> strImage = new List<string>();
List<string> strShader = new List<string>();
List<string> strOther = new List<string>();
List<string> strMaterials = new List<string>();
foreach (var p in strPathList)
｛
string strCase = "null";
if (p.Contains("."))
｛
strCase = p.Split('.')[1];
｝
switch (strCase.ToLower())
｛
case "prefab":
case "cs":
strPrefab.Add(p);
break;
case "fbx":
strModel.Add(p);
break;
case "shader":
strShader.Add(p);
break;
case "mat":
strMaterials.Add(p);
break;
case "png":
case "jpg":
case "tga":
case "psd":
strImage.Add(p);
break;
default:
strOther.Add(p);
break;
｝
｝
abBuilds[0].assetNames = strPrefab.ToArray();
abBuilds[0].assetBundleName = "assetBundlePrefab";
abBuilds[1].assetNames = strModel.ToArray();
abBuilds[1].assetBundleName = "assetBundleModel";
abBuilds[2].assetNames = strImage.ToArray();
abBuilds[2].assetBundleName = "assetBundleImage";
abBuilds[3].assetNames = strShader.ToArray();
abBuilds[3].assetBundleName = "assetBundleShader";
abBuilds[4].assetNames = strMaterials.ToArray();
abBuilds[4].assetBundleName = "assetBundleMaterials";
abBuilds[5].assetNames = strOther.ToArray();
abBuilds[5].assetBundleName = "assetBundleOther";
BuildPipeline.BuildAssetBundles(targetPath, abBuilds, BuildAssetBundleOptions.CollectDependencies, BuildTarget.Android);
AssetDatabase.Refresh();
｝
static void WriteVersion()
｛
StreamWriter sw = new StreamWriter(Application.streamingAssetsPath + "/version.txt");
string w = "1";
sw.Write(w);
sw.Close();
｝
｝已经设置好的贴图文件最好再设置以便脚本记录生成版本号到version.txt文件，设置后保存。已经设置此步骤后，添加材质后，在加载资源时脚本会自动添加相应版本号。
再将工程发给小伙伴，重新打开加载资源时，就可以防止材质贴图丢失了。
