Unity3D Editor：如何找到给定资产的所有用法？

Question

非常有用的功能"Find usages"存在于Visual Studio和Resharper中，但我在Unity3D Editor中找不到相同的功能。我在Unity3d中只看到"Select dependencies"，但我需要相反的。存在吗？

Answer 1

从编辑器中，转到项目选项卡，select给定的资产，右键单击它，然后单击在其中查找引用场景。如果给定资产是脚本，它将在 层次视图 中向您显示给定资产附加到的每个游戏对象。如果它是图像、音频文件或预制件，它会在 Hierarchy View.

中显示哪个 GameObject 正在使用该资产

Answer 2

遗憾的是，Unity Editor 仅允许您在场景中查找资源的用法。

此外，您得到的是使用它的选定资产列表，因此在更改鼠标焦点后您将失去选择

Asset Store 上有一个解决方案可以：

在项目和场景视图中查找资产的所有用法
在单独的 window 中展示结果，显示使用目标资产的特定字段
允许您用拖放替换特定的资源使用

Unity Answers 中的这个脚本做得很好。（也可以很容易地稍微调整以改进其功能）

Answer 4

免费的开源工具 Dependencies-Hunter 可以完成这项工作：查找给定资产的所有 dependencies/usages。它还可以执行完整的项目分析以找到所有未使用的资产。

它由一个脚本组成，因此只需将其复制粘贴到您的项目中即可。

它在内部使用 AssetDatabase.GetDependencies 构建所有资产的地图以用于分析。

所以它有两个选项可供使用：

它在资产上下文菜单中添加了一个选项“在项目中查找引用”，该菜单显示了该特定资产具有的依赖项。 The resulting window looks like this
还有一个选项可以通过单独的编辑器查找项目中所有未使用的资产 window。您可以通过指定要忽略的内容的 RegExp 模式来过滤资产以进行分析。

Answer 5

以上解决方案实际上是不正确的。 Unity 确实支持在项目视图中查找对资产的引用，但没有按钮。您必须在项目视图搜索栏中手动输入查询：带有文件扩展名的“ref:Assets//”。当您在场景中查找引用时，这与它放入场景视图搜索中的查询完全相同。 unity 需要一点时间来“思考”，但它最终会吐出对你的 asset/script.
