Unity3D研究院之查找资源被哪里引用了
Unity3D研究院之查找资源被哪里引用了
https://www.xuanyusong.com/archives/4207
Unity提供了一个方法 AssetDatabase.GetDependencies()，但是它只能查找这个资源引用了那些资源。 但是我想要的是查找某个资源被那些资源引用了，这是两种相反的查找公式。 其实网上也有很多这样的插件了，似乎代码量都太多了。昨天晚上加班时脑洞打开，想到了一个简单的方法。通过GUID全局搜索匹配。。几行代码就能搞定～～
如下图所示，右键随便选择一个资源，点击 Find References。
然后开始匹配资源。
匹配结束后会把匹配到的资源Log出来。以下代码直接放到你的工程里就可以直接用。
C#

public class FindReferences {
[MenuItem("Assets/Find References", false, 10)] static private void Find() { EditorSettings.serializationMode = SerializationMode.ForceText; string path = AssetDatabase.GetAssetPath(Selection.activeObject); if (!string.IsNullOrEmpty(path)) { string guid = AssetDatabase.AssetPathToGUID(path); List withoutExtensions = new List(){".prefab",".unity",".mat",".asset"}; string[] files = Directory.GetFiles(Application.dataPath, "*.*", SearchOption.AllDirectories) .Where(s => withoutExtensions.Contains(Path.GetExtension(s).ToLower())).ToArray(); int startIndex = 0;
EditorApplication.update = delegate() { string file = files[startIndex];
bool isCancel = EditorUtility.DisplayCancelableProgressBar("匹配资源中", file, (float)startIndex / (float)files.Length);
if (Regex.IsMatch(File.ReadAllText(file), guid)) { Debug.Log(file, AssetDatabase.LoadAssetAtPath<Object>(GetRelativeAssetsPath(file))); }
startIndex++; if (isCancel || startIndex >= files.Length) { EditorUtility.ClearProgressBar(); EditorApplication.update = null; startIndex = 0; Debug.Log("匹配结束"); }
}; } }
[MenuItem("Assets/Find References", true)] static private bool VFind() { string path = AssetDatabase.GetAssetPath(Selection.activeObject); return (!string.IsNullOrEmpty(path)); }
static private string GetRelativeAssetsPath(string path) { return "Assets" + Path.GetFullPath(path).Replace(Path.GetFullPath(Application.dataPath), "").Replace('\\', '/'); } } |
美中不足的地方就是查找速度了。。其实正则表达式匹配的速度还是很快，慢的地方是File.ReadAllText(file) 如果大家有更好的办法，欢迎推荐～
今天我无意发现了一个更快的方法，可惜只能在mac上用。比我上面的方法要快N倍啊，快的丧心病狂啊～欢迎大家用啊～～。。。
