c# - 使用检查器为动态列表分配 ButtonClickedEvent 时出现 Unity 2018 错误

问题描述

我写了一些动态列表来填写统一检查员，

[Serializable]
public class MenuItem
{
    public string title = "Item";
    public bool enabled = true;
    public Button.ButtonClickedEvent onClick = null;
    public MenuItem[] submenu;
}
public MenuItem[] menu = null;

现在，当我使用检查器为菜单分配值时，第一级一切正常。但是在第二级之后，我无法将 ButtonClickedEvent 分配给创建的 MenuItem 子项。我在统一编辑器中收到此错误：

type is not a enum value
UnityEditor.SerializedProperty:set_enumValueIndex(Int32)
UnityEditorInternal.UnityEventDrawer:AddEventListener(ReorderableList) (at C:/buildslave/unity/build/Editor/Mono/Inspector/UnityEventDrawer.cs:355)
UnityEditorInternal.Defaults:DrawFooter(Rect, ReorderableList) (at C:/buildslave/unity/build/Editor/Mono/GUI/ReorderableList.cs:115)
UnityEditorInternal.ReorderableList:DoListFooter(Rect) (at C:/buildslave/unity/build/Editor/Mono/GUI/ReorderableList.cs:641)
UnityEditorInternal.ReorderableList:DoList(Rect) (at C:/buildslave/unity/build/Editor/Mono/GUI/ReorderableList.cs:413)
UnityEditorInternal.UnityEventDrawer:OnGUI(Rect) (at C:/buildslave/unity/build/Editor/Mono/Inspector/UnityEventDrawer.cs:148)
UnityEditorInternal.UnityEventDrawer:OnGUI(Rect, SerializedProperty, GUIContent) (at C:/buildslave/unity/build/Editor/Mono/Inspector/UnityEventDrawer.cs:117)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

在检查器中，我看到一个奇怪的 0。 带有 ButtonClickedEvent 的动态列表的统一检查器错误

解决方案

这里 UnityEvent Editor 打破了嵌套结构 ，有一个答案建议使用 ScriptableObject 而不是递归列表。但是没有HOW！

但请注意答案的重点，如果我有特定的级别数，我可以使用这样的东西

[Serializable]
public class MenuItem
{
    public string title = "Item";
    public bool enabled = true;
    public int width = 100;
    public string relatedLeftDockPanel = "";
    public string relatedRightDockPanel = "";
    public Button.ButtonClickedEvent onClick = null;
    public MenuItemLevel1[] submenu;
}

[Serializable]
public class MenuItemLevel1
{
    public string title = "Item";
    public bool enabled = true;
    public int width = 100;
    public string relatedLeftDockPanel = "";
    public string relatedRightDockPanel = "";
    public Button.ButtonClickedEvent onClick = null;
    public MenuItemLevel2[] submenu;
}

[Serializable]
public class MenuItemLevel2
{
    public string title = "Item";
    public bool enabled = true;
    public int width = 100;
    public string relatedLeftDockPanel = "";
    public string relatedRightDockPanel = "";
    public Button.ButtonClickedEvent onClick = null;
}

编辑：甚至更好

public class MenuItem
{
    public string title = "Item";
    public bool enabled = true;
    public int width = 100;
    public string relatedLeftDockPanel = "";
    public string relatedRightDockPanel = "";
    public Button.ButtonClickedEvent onClick = null;
}

[Serializable]
public class MenuItemLevel0 : MenuItem
{
    public MenuItemLevel1[] submenu;
}

[Serializable]
public class MenuItemLevel1 : MenuItem
{
    public MenuItemLevel2[] submenu;
}

[Serializable]
public class MenuItemLevel2 : MenuItem
{
}

它解决了这个问题，但我想有一些更好的解决方案。
