1 说明

​ 本文介绍 Odin Inspector 插件中条件特性的使用方法。

2 条件特性

2.1 DisableIf / EnableIf

如果解析的字符串计算结果为指定值，则禁用 / 启用 Inspector 窗口中的属性更改。

• string condition

  检查值条件的解析字符串，如成员名称、表达式等。

• object optionalValue

  要检查的值。

// DisableIfExamplesComponent.cs

using Sirenix.OdinInspector;
using UnityEngine;

public class DisableIfExamplesComponent : MonoBehaviour
{
    public UnityEngine.Object SomeObject;

    [EnumToggleButtons]
    public InfoMessageType SomeEnum;

    public bool IsToggled;

    [DisableIf("SomeEnum", InfoMessageType.Info)]
    public Vector2 Info;

    [DisableIf("SomeEnum", InfoMessageType.Error)]
    public Vector2 Error;

    [DisableIf("SomeEnum", InfoMessageType.Warning)]
    public Vector2 Warning;

    [DisableIf("IsToggled")]
    public int DisableIfToggled;

    [DisableIf("SomeObject")]
    public Vector3 EnabledWhenNull;

    [DisableIf("@this.IsToggled && this.SomeObject != null || this.SomeEnum == InfoMessageType.Error")]
    public int DisableWithExpression;
}

2.2 DisableIn / EnableIn / ShowIn / HideIn

当该对象所在的脚本挂载在何种预制体上，其修饰的对象禁止 / 允许在 Inspector 窗口中的更改 / 显示。

• PrefabKind prefabKind

  预制体的种类。

  1. None

     所有预制体，都不满足条件。

  2. InstanceInScene

     场景中的预制体实例。

  3. InstanceInPrefab

     嵌套在其他预制体中的预制件实例。

  4. Regular

     常规预制体。

  5. Variant

     预制体资产。

  6. NonPrefabInstance

     非预制体或场景中的游戏对象实例。

  7. PrefabInstance = InstanceInPrefab | InstanceInScene

     常规预制体的实例，以及场景中或嵌套在其他预制体中的预制体。

  8. PrefabAsset = Variant | Regular

     常规预制体和预制体资产。

  9. PrefabInstanceAndNonPrefabInstance = PrefabInstance | NonPrefabInstance

     预制体以及非预制实例。

  10. All = PrefabInstanceAndNonPrefabInstance | PrefabAsset

      所有预制体。

using System.Collections;
using System.Collections.Generic;
using Sirenix.OdinInspector;
using UnityEngine;

public class Test : MonoBehaviour
{
    [DisableIn(PrefabKind.PrefabAsset)]
    public int i;
}

2.3 DisableInEditorMode / HideInEditorMode

在不处于播放模式时禁用 / 隐藏对象。只希望在播放模式下可编辑 / 显示时，可使用此选项。

// DisableInEditorModeExamplesComponent.cs

using Sirenix.OdinInspector;
using UnityEngine;

public class DisableInEditorModeExamplesComponent : MonoBehaviour
{
    [Title("Disabled in edit mode")]
    [DisableInEditorMode]
    public GameObject A;

    [DisableInEditorMode]
    public Material B;
}

2.4 DisableInInlineEditors / ShowInInlineEditors / HideInInlineEditors

如果对象被 InlineEditor 特性绘制，则该对象在 Inspector 窗口中禁用更改 / 显示 / 隐藏。

补充 InlineEditor 特性：将继承 UnityEngine.Object 的类（如 ScriptableObject）的详细信息显示在 Inspector 窗口。

​ 数据结构类：

using UnityEngine;

#nullable disable
namespace Sirenix.OdinInspector.Editor.Examples
{
  public class DisabledInInlineEditorScriptableObject : ScriptableObject
  {
    public string AlwaysEnabled;
    [DisableInInlineEditors]
    public string DisabledInInlineEditor;
  }
}

​ 挂载的脚本：

// DisableInInlineEditorExampleComponent.cs

using Sirenix.OdinInspector;
using UnityEngine;

#if UNITY_EDITOR // Editor namespaces can only be used in the editor.
using Sirenix.OdinInspector.Editor.Examples;
#endif

public class DisableInInlineEditorExampleComponent : MonoBehaviour
{
#if UNITY_EDITOR // DisabledInInlineEditorScriptableObject is an example type and only exists in the editor
    [InfoBox("Click the pen icon to open a new inspector window for the InlineObject too see the difference this attribute makes.")]
    [InlineEditor(Expanded = true)]
    public DisabledInInlineEditorScriptableObject InlineObject;
#endif

#if UNITY_EDITOR // Editor-related code must be excluded from builds
    [OnInspectorInit]
    private void CreateData() {
        InlineObject = ExampleHelper.GetScriptableObject<DisabledInInlineEditorScriptableObject>("Inline Object");
    }

    [OnInspectorDispose]
    private void CleanupData() {
        if (InlineObject != null) Object.DestroyImmediate(InlineObject);
    }
#endif
}

2.5 DisableInPlayMode / HideInPlayMode

在处于播放模式时禁用 / 隐藏对象。只希望在编辑模式下可编辑 / 显示时，可使用此选项。

// DisableInPlayModeExamplesComponent.cs

using Sirenix.OdinInspector;
using UnityEngine;

public class DisableInPlayModeExamplesComponent : MonoBehaviour
{
    [Title("Disabled in play mode")]
    [DisableInPlayMode]
    public int A;

    [DisableInPlayMode]
    public Material B;
}

2.6 ShowIf / HideIf

如果解析的字符串计算结果为指定值，则在 Inspector 窗口中显示 / 隐藏该对象。

• string condition

  检查值条件的解析字符串，如成员名称、表达式等。

• object optionalValue

  要检查的值。

• bool animate = true

  状态改变时是否启用滑入和滑出动画显示。

// ShowAndHideIfExamplesComponent.cs
using Sirenix.OdinInspector;
using UnityEngine;

public class ShowAndHideIfExamplesComponent : MonoBehaviour
{
    // Note that you can also reference methods and properties or use @expressions. You are not limited to fields.
    public UnityEngine.Object SomeObject;
    
    [EnumToggleButtons]
    public InfoMessageType SomeEnum;
    
    public bool IsToggled;
    
    [ShowIf("SomeEnum", InfoMessageType.Info)]
    public Vector3 Info;
    
    [ShowIf("SomeEnum", InfoMessageType.Warning)]
    public Vector2 Warning;
    
    [ShowIf("SomeEnum", InfoMessageType.Error)]
    public Vector3 Error;
    
    [ShowIf("IsToggled")]
    public Vector2 VisibleWhenToggled;
    
    [HideIf("IsToggled")]
    public Vector3 HiddenWhenToggled;
    
    [HideIf("SomeObject")]
    public Vector3 ShowWhenNull;
    
    [ShowIf("SomeObject")]
    public Vector3 HideWhenNull;
    
    [EnableIf("@this.IsToggled && this.SomeObject != null || this.SomeEnum == InfoMessageType.Error")]
    public int ShowWithExpression;
}

2.7 ShowIfGroup / HideIfGroup

满足某个条件，则显示 / 隐藏指定组。

• string path

  指定组的路径。

• object value

  与路径末尾的标签重名的属性等于该值时，则满足条件。

• bool animate = true

  状态改变时是否启用滑入和滑出动画显示。

// HideIfGroupExampleComponent.cs

using Sirenix.OdinInspector;
using UnityEngine;

public class HideIfGroupExampleComponent : MonoBehaviour
{
    public bool Toggle = true;

    [HideIfGroup("Toggle")]
    [BoxGroup("Toggle/Shown Box")]
    public int A, B;

    [BoxGroup("Box")]
    public InfoMessageType EnumField = InfoMessageType.Info;

    [BoxGroup("Box")]
    [HideIfGroup("Box/Toggle")]
    public Vector3 X, Y;

    // Like the regular If-attributes, HideIfGroup also supports specifying values.
    // You can also chain multiple HideIfGroup attributes together for more complex behaviour.
    [HideIfGroup("Box/Toggle/EnumField", Value = InfoMessageType.Info)]
    [BoxGroup("Box/Toggle/EnumField/Border", ShowLabel = false)]
    public string Name;

    [BoxGroup("Box/Toggle/EnumField/Border")]
    public Vector3 Vector;

    // HideIfGroup will by default use the name of the group,
    // but you can also use the MemberName property to override this.
    [HideIfGroup("RectGroup", Condition = "Toggle")]
    public Rect Rect;
}
