C# 我可以在CreateAssetMenu中设置子文件夹的排序顺序吗？,c#,unity3d,unity-editor,C#,Unity3d,Unity Editor,在为可编写脚本的对象使用CreateAssetMenu时，是否可以设置文件夹的顺序例如，如果我有这些类 [CreateAssetMenu(menuName = "My Objects/First Thing", order = 1)] public class FirstThing : ScriptableObject { } [CreateAssetMenu(menuName = "My Objects/Second Thing", order =

在为可编写脚本的对象使用CreateAssetMenu时，是否可以设置文件夹的顺序

例如，如果我有这些类

[CreateAssetMenu(menuName = "My Objects/First Thing", order = 1)]
public class FirstThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Second Thing", order = 2)]
public class SecondThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Third Thing", order = 3)]
public class ThirdThing : ScriptableObject
{
}

然后，当我在项目窗口中单击鼠标右键并选择“创建”时，关联菜单将按以下顺序显示我的菜单选项

Create -> My Objects -> First Thing
          |-----------> Second Thing
          |-----------> Third Thing

但是，一旦我开始将菜单选项组织到子文件夹中，我就找不到控制子文件夹顺序的方法。例如，如果我现在有这个

[CreateAssetMenu(menuName = "My Objects/Things/First Thing", order = 1)]
public class FirstThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Things/Second Thing", order = 2)]
public class SecondThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Things/Third Thing", order = 3)]
public class ThirdThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Widgets/First Widget", order = 1)]
public class FirstWidget: ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Widgets/Second Widget", order = 2)]
public class SecondWidget: ScriptableObject
{
}

现在创建上下文菜单如下所示

Create -> My Objects -> Things --> First Thing
          |             |--------> Second Thing
          |             |--------> Third Thing
          |-----------> Widgets -> First Widget
                        |--------> Second Widget

是否有一种方法可以控制物品和小部件文件夹的顺序，类似于我如何控制其父文件夹中第一件事、第二件事等的顺序？

从中，可以在下面的“排序详细信息”下的Unity菜单中传播有关排序顺序的一些详细信息，您可以发现：

自定义子菜单组本身相对于菜单项的排序优先级有点棘手。子菜单组将按照自定义菜单项首次创建时的优先级进行排序

或者换句话说：子文件夹按其中第一个元素的顺序值排序

由于您的两个子文件夹都以1开头，因此它们按字母顺序排序为后备

因此，为了将Things菜单置于Widgets文件夹下，只需确保元素具有绝对较高的值，例如

[CreateAssetMenu(menuName = "My Objects/Things/First Thing", order = 11)]
public class FirstThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Things/Second Thing", order = 12)]
public class SecondThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Things/Third Thing", order = 13)]
public class ThirdThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Widgets/First Widget", order = 1)]
public class FirstWidget: ScriptableObject
{
}

[CreateAssetMenu(menuName = "My Objects/Widgets/Second Widget", order = 2)]
public class SecondWidget: ScriptableObject
{
}

也许它甚至足以取代2，3，4的东西项目

这将导致

Create -> My Objects -> Widgets -> First Widget
          |             |--------> Second Widget
          |
          |-----------> Things --> First Thing
                        |--------> Second Thing
                        |--------> Third Thing

另注

如果您的物品优先级大于或等于11，Unity将在您的物品前创建一个分隔符

小心点：

顺便说一句，如果更改菜单项的现有排序优先级，您可能看不到它在菜单中的反映。我认为Unity正在缓存该值，因此要更新它，您可以重新启动编辑器，或者做一些练习，首先从属性中删除优先级，然后进行编译，然后添加新的优先级

小贴士：为了使维护更容易，我通常会有一个带有常数的中心类，并执行一些操作，例如

public static class Constants
{
    public static string MENU = "My Objects/";
    public static string MENU_THINGS = MENU + "Things/";
    public static string MENU_WIDGETS = MENU + "Widgets/";

    public static int ORDER_WIDGETS = 0;
    public static int ORDER_THINGS = 10;
}

然后呢

[CreateAssetMenu(menuName = Constants.MENU_THINGS + "First Thing", order = Constants.ORDER_THINGS + 1)]
public class FirstThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = Constants.MENU_THINGS + "Second Thing", order = Constants.ORDER_THINGS + 2)]
public class SecondThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = Constants.MENU_THINGS + "Third Thing", order = Constants.ORDER_THINGS + 3)]
public class ThirdThing : ScriptableObject
{
}

[CreateAssetMenu(menuName = Constants.MENU_WIDGETS + "First Widget", order = Constants.ORDER_WIDGETS + 1)]
public class FirstWidget: ScriptableObject
{
}

[CreateAssetMenu(menuName = Constants.MENU_WIDGETS + "Second Widget", order = Constants.ORDER_WIDGETS + 2)]
public class SecondWidget: ScriptableObject
{
}
