Odin Inspector 系列教程 --- Asset Selector Attribute

本文主要是介绍Odin Inspector 系列教程 --- Asset Selector 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！

Asset Selector Attribute 特性用于：在对象字段旁边添加一个小按钮，该按钮将向用户显示资产下拉列表，以便从属性中进行选择。

【AssetSelector】添加到对应的字段上即可

    [AssetSelector]public Material AnyAllMaterials;[AssetSelector]public Material[] ListOfAllMaterials;

【FlattenTreeView】是否开启树状图

    [PropertySpace(40)][AssetSelector(FlattenTreeView = false)]//默认树状显示public PhysicMaterial TreeView;[AssetSelector(FlattenTreeView = true)]//非默认树状显示public PhysicMaterial NoTreeView;

【Paths】单路径或多路径查找

    [PropertySpace(40)][AssetSelector(Paths = "Assets/TutorialAsset/ExampleScriptableObjects")]public ScriptableObject ScriptableObjectsFromFolder;[AssetSelector(Paths = "Assets/TutorialAsset/ExampleScriptableObjects|Assets/Plugins/Sirenix/Odin Inspector")]public ScriptableObject ScriptableObjectsFromMultipleFolders;

【Filter】自定义过滤条件

    [PropertySpace(40)][AssetSelector(Filter = "New Animation t:AnimationClip l:自定义标签")]public UnityEngine.Object AssetDatabaseSearchFilters;

【DisableListAddButtonBehaviour】开启后加号不会出现树形下拉条以弹窗形式出现

    [Title("辅助性功能")][AssetSelector(DisableListAddButtonBehaviour = true)] //开启后加号不会出现树形下拉条以弹窗形式出现public List<GameObject> DisableListAddButtonBehaviour;

【DrawDropdownForListElements】控制已经添加的Item是否含有下拉列表

    [PropertySpace(40)][AssetSelector(DrawDropdownForListElements = false)]public List<GameObject> DisableListElementBehaviour_False;[AssetSelector(DrawDropdownForListElements = true)]public List<GameObject> DisableListElementBehaviour_True;

【ExcludeExistingValuesInList】去除已经含有的Item

    [PropertySpace(40)][AssetSelector(ExcludeExistingValuesInList = true)]public List<GameObject> ExcludeExistingValuesInList_True;[AssetSelector(ExcludeExistingValuesInList = false)]public List<GameObject> ExcludeExistingValuesInList_False;

【IsUniqueList】开启列表勾选模式（这个关键字在Odin的很多特性中都有）

    [PropertySpace(40)][AssetSelector(IsUniqueList = true)]public List<GameObject> DisableUniqueListBehaviour_True;[AssetSelector(IsUniqueList = false)]public List<GameObject> DisableUniqueListBehaviour_False;

【ExpandAllMenuItems】下拉列表是否强制展开

    [PropertySpace(40)][AssetSelector(ExpandAllMenuItems = true)]//下拉条是否展开public List<GameObject> ExpandAllMenuItems_True;[AssetSelector(ExpandAllMenuItems = false)]public List<GameObject> ExpandAllMenuItems_False;

【DropdownTitle】下拉列表标题

    [PropertySpace(40)][AssetSelector(DropdownTitle = "最定义下拉列表标题")]public List<GameObject> CustomDropdownTitle;
