大家好，又见面了，我是你们的朋友全栈君。

List Drawer Settings Attribute 自定义数组或者列表绘制方式

Odin已经重写对应的数组和列表的绘制

    [Title("List Basics")]
    [InfoBox("现在可以拖动列表元素来重新排序并逐个删除它们，并且列表具有分页功能(尝试添加大量元素!)您仍然可以从项目视图一次将许多资产拖到列表中—只需将它们拖到列表本身，并将它们插入到您想要添加它们的地方.")]
    public List<float> FloatList;

将[Range]属性应用于此列表，代替传统的float形式

    [InfoBox("将[Range]属性应用于此列表，代替传统的float形式")]
    [Range(0, 1)]
    public float[] FloatRangeArray;

不同方式的只读方式

    [ListDrawerSettings(IsReadOnly = true)]
    public int[] ReadOnlyArray1 = new int[] { 1, 2, 3 };
    [ReadOnly]
    public int[] ReadOnlyArray2 = new int[] { 1, 2, 3 };

负责数据结构的数组或列表

    public SomeOtherStruct[] SomeStructList;

自定义page每页的个数

    [Title("Advanced List Customization")]
    [InfoBox("Using [ListDrawerSettings], lists can be customized in a wide variety of ways.")]
    [ListDrawerSettings(NumberOfItemsPerPage = 5)]
    public int[] FiveItemsPerPage;

显示对应元素的索引和指定其元素的标签

    [ListDrawerSettings(ShowIndexLabels = true, ListElementLabelName = "SomeString")]
    public SomeStruct[] IndexLabels;

禁止拖拽item，禁止翻页，禁止显示item个数

    [ListDrawerSettings(DraggableItems = false, Expanded = false, ShowIndexLabels = true, ShowPaging = false, ShowItemCount = false, HideRemoveButton = true)]
    public int[] MoreListSettings = new int[] { 1, 2, 3 };

【OnBeginListElementGUI】【OnEndListElementGUI】在每个列表元素的前后调用一个函数，并传入对应元素的索引

    [ListDrawerSettings(OnBeginListElementGUI = "BeginDrawListElement", OnEndListElementGUI = "EndDrawListElement")]
    public SomeStruct[] InjectListElementGUI;
    private void BeginDrawListElement(int index)
    {
        SirenixEditorGUI.BeginBox(this.InjectListElementGUI[index].SomeString);
    }
    private void EndDrawListElement(int index)
    {
        SirenixEditorGUI.EndBox();
    }

使用它将自定义GUI注入到列表的标题栏中。

    [ListDrawerSettings(OnTitleBarGUI = "DrawRefreshButton")]
    public List<int> CustomButtons;
    private void DrawRefreshButton()
    {
        if (SirenixEditorGUI.ToolbarButton(EditorIcons.Refresh))
        {
            Debug.Log(this.CustomButtons.Count.ToString());
        }
    }

【CustomAddFunction 】覆盖将对象添加到列表的默认行为。如果引用的成员返回列表类型元素，则将对每个选定对象调用该元素一次。如果引用的方法返回void，那么不管选择了多少对象，它都只会被调用一次。

    [ListDrawerSettings(CustomAddFunction = "CustomAddFunction")]
    public List<int> CustomAddBehaviour;
    private int CustomAddFunction()
    {
        return this.CustomAddBehaviour.Count+100;
    }

    }
