Odin Inspector 系列教程 --- List Drawer Settings Attribute

本文主要是介绍Odin Inspector 系列教程 --- List Drawer Settings Attribute，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

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;}
