命名 MonoBehaviour 类 GameManager 时的特殊图标 [英] Special Icon when naming a MonoBehaviour class GameManager
问题描述
Unity 中的GameManager 名称是否有什么特别之处，导致设计者采取不同的行动?我有一个名为 GameManager 的类，它是从 ScriptableObject 派生的，设计者对该类做了一些与我的其他 ScriptableObject 派生不同的事情类.
Is there something special about the name GameManager in Unity that causes the designer to act differently? I have a class named GameManager that is derived from ScriptableObject, and the designer is doing a few things differently for that class versus my other ScriptableObject derived classes.
我可以通过将名称从 GameManager 更改为 Manager 来验证此行为，并且 Unity 编辑器的行为有所不同.
I can verify this behavior by changing the name from GameManager to Manager, and the Unity editor acts differently.
我对GameManager的定义如下:
[CreateAssetMenu(menuName = "Managers/GameManager")]
public class GameManager : ScriptableObject
{
// ...
}
当我的 C# 类命名为 GameManager 时，项目视图如下所示.注意 Game Manager 旁边的不同图标.
Here's what the Project view looks like when my C# class is named GameManager. Notice the different icon next to Game Manager.
如果我删除该资产，将底层 C# 类名称更改为 Manager，然后再次创建该资产，则图标是普通图标，而不是齿轮.
If I delete that asset, change the underlying C# class name to Manager, and then create the asset again, the icon is the normal icon, rather than being the gear.
另一个更严重的问题是，如果我有一个游戏对象，其中包含一个 MonoBehaviour，它具有 GameManager 类型的属性，则 Unity 获胜当我单击检查器中字段旁边的小圆圈图标时，不会向我显示现有的 GameManager 资产.Unity 将让我将 GameManager 资产从项目视图拖到该字段中，但 Unity 不允许我通过单击该字段来选择引用.如下面的屏幕截图所示，Unity 没有给我选择我的 GameManager 资产的选项，即使它在项目视图中可用.
The other issue, which is more of a problem, is that if I have a game object that includes a MonoBehaviour that has a property of type GameManager, Unity won't show me the existing GameManager asset when I click on the little circle icon next to the field in the Inspector. Unity will let me drag the GameManager asset from the Project view into the field, but Unity won't let me select the reference by clicking in the field. As shown in the screenshots below, Unity doesn't give me the option of selecting my GameManager asset, even though it's available in the Project view.
但是，如果我将底层 C# 类的名称从 GameManager 更改为 Manager，Unity 编辑器将正常工作，如下所示.
However, If I change the name of the underlying C# class from GameManager to Manager, the Unity editor works correctly, as shown below.
GameManager 的 C# 类名是否有什么特别之处，或者这种行为可能是由于其他原因造成的?
Is there something special about the C# class name of GameManager, or could this behavior be due to something else?
推荐答案
Unity 中有一些特殊的脚本名称.当您使用其中任何一个时，特殊图标将应用于该脚本.GameManager 是特殊的脚本名称之一.Search 也是 Unity 中另一个特殊的脚本名称.不幸的是，它们并未在 Unity 网站的某处列出，但您绝对会知道何时使用了特殊脚本名称之一.
There are special scripts names in Unity. When you use any of those, special icon is applied to that script. GameManager is one of the special script names. Search is also another special script name in Unity. Unfortunately, they are not listed somewhere on Unity's website but you will absolutely know when you are using one of the special script names.
如果您仍想使用这些特殊名称来命名您的脚本，并且还想删除特殊图标或行为，请将带有特殊名称的脚本括在命名空间中.
If you still want to use those special names to name your script and also want to remove the special icons or behavior, enclose that script with the special name in a namespace.
namespace Ben
{
public class Search : MonoBehaviour
{
}
}
Search 脚本的特殊图标现在应该消失了.这也适用于 GameManager 脚本.
The special icon for the Search script should now be gone. This also applies to the GameManager script.
编辑:
由于人们想了解更多，基本上，Unity 有这些包含其图标的重要文件:
Since people want to know more about this, basically, Unity has these important files that contains its icons:
unity 默认资源Unity 编辑器资源unity_builtin_extra
在 .asset，您将能够看到资产当您展开这些文件时，这些文件中的图标和图标.
in the <UnityInstallationDirecory>EditorDataResources directory. If you copy these files to your <ProjectDirecory>AssetsResources directory and change the files extension of three of them to .asset, you will be able to see assets and icon in those files when you expand them.
找到特殊图标的秘诀在于，任何名称以 "Icon" 结尾的图标都可能是特殊图标.例如，GameManager 有一个名为 GameManager Icon 的图标.将您的脚本命名为 GameManager 将使其使用 GameManager Icon.这并不完全适用于所有图标，而是大多数.很少有人不这样做.
The secret to finding the special icons is that any of those icons that has a named that ends with " Icon" is likely a special icon. For example, GameManager has an icon named GameManager Icon. Naming your script GameManager will make it use the GameManager Icon. This is not entirely true for all icon but most of them. Few don't do this.
我制作了一个脚本来在编辑器中自动执行上述指令.它适用于 Unity 2017，但在 Unity 2018 中似乎存在问题，我没有时间修复它.它在执行时在 Unity 2018 中显示许多错误，但之后它仍然可以正常工作.
I made a script to automate the instruction above in the Editor. It works in Unity 2017 but there seems to be issues with it in Unity 2018 and I haven't gotten some time to fix it. It shows many error in Unity 2018 when executed but it still works fine after that.
