UnityEditor开发教程之检查重复Sprite
发表于2018-10-08
本篇文章主要给大家分享下检查Unity中重复的Sprite资源与名称重复的Sprite，其中打包图集使用unity2017中的新功能SpriteAtlas，想知道方法的可以看看。
代码如下：
[MenuItem("Tools/Atlas/Check Atlas")]
public static void CheckAtlas()
｛
EditorUtility.DisplayProgressBar("Check Repetition", "Check Repetition", 0.5f);
FileTool.q = new Queue<string>();
FileTool.ListFiles(new DirectoryInfo(System.Environment.CurrentDirectory + "/" + "Assets/AssetbundleHUD/"));
string[] s = FileTool.q.ToArray();
int filesLength = (System.Environment.CurrentDirectory + "/" + "Assets/AssetbundleHUD/HUDIF2/").Length;
Dictionary<string, string> spriteDic = new Dictionary<string, string>();
Dictionary<string, string> MD5Dic = new Dictionary<string, string>();
foreach (string ss in s)
｛
string AssetPath = ss.Substring(filesLength, ss.Length - filesLength);
checkMD5(MD5Dic, ss);
string[] sub = AssetPath.Split('\\');
string SpriteName = sub[sub.Length - 1];
if (spriteDic.ContainsKey(SpriteName))
｛
Debug.LogError("Sprite 名称 重复，SpriteName :" + SpriteName + ",\n path: " + spriteDic[SpriteName] + ",\n path:" + ss);
｝
else
｛
spriteDic.Add(SpriteName, ss);
｝
｝
EditorUtility.ClearProgressBar();
EditorUtility.DisplayProgressBar("Check Compare", "Check Compare", 0.5f);
CompareAtlasSpriteCount();
EditorUtility.ClearProgressBar();
｝
private static void CompareAtlasSpriteCount()
｛
FileTool.q = new Queue<string>();
FileTool.ListFiles(new DirectoryInfo(System.Environment.CurrentDirectory + "/" + "Assets/AssetbundleResources/Atlas/"));
string[] s = FileTool.q.ToArray();
int filesLength = (System.Environment.CurrentDirectory + "/").Length;
Dictionary<string, string> spriteDic = new Dictionary<string, string>();
foreach (string ss in s)
｛
string AssetPath = ss.Substring(filesLength, ss.Length - filesLength);
string[] sub = AssetPath.Split('\\');
string AtlasName = sub[sub.Length - 1];
int length = ".spriteatlas".Length;
AtlasName = AtlasName.Substring(0, AtlasName.Length - length);
SpriteAtlas spriteAtlas = UnityEditor.AssetDatabase.LoadAssetAtPath(AssetPath, typeof(SpriteAtlas)) as SpriteAtlas;
if (spriteAtlas == null)
continue;
int AtlasSpriteCount = spriteAtlas.spriteCount;
string TexturFiles = System.Environment.CurrentDirectory + "/" + "Assets/AssetbundleHUD/HUDIF2";
if (!ss.Contains("single")) //大图集不用检查吧 都是单张的
｛
FileTool.q = new Queue<string>();
FileTool.ListFiles(new DirectoryInfo(TexturFiles + "/" + AtlasName));
int TextueCount = FileTool.q.Count;
if (TextueCount != AtlasSpriteCount)
｛
Debug.LogError(AtlasName + "图集中Sprite数量与资源不一致！");
｝
｝
｝
｝
private static void checkMD5(Dictionary<string, string> DIC, string path)
｛
try
｛
FileStream fs = new FileStream(path, FileMode.Open);
int len = (int)fs.Length;
byte[] data = new byte[len];
fs.Read(data, 0, len);
fs.Close();
MD5 md5 = new MD5CryptoServiceProvider();
byte[] result = md5.ComputeHash(data);
string fileMD5 = "";
foreach (byte b in result)
｛
fileMD5 += Convert.ToString(b, 16);
｝
if (DIC.ContainsKey(fileMD5))
｛
Debug.LogError("Sprite 资源 重复：MD5:" + fileMD5+ ",\n path" + path + "\n path" + DIC[fileMD5]);
｝
else
｛
DIC.Add(fileMD5, path);
｝
｝
catch (FileNotFoundException e)
｛
Debug.LogError(e.Message);
｝
｝
