EditorApplication.contextualPropertyMenu

Description

每当用户上下文单击 Inspector 中的属性时引发的回调。

对于添加可对特定属性执行操作的自定义上下文菜单项而言，此回调非常有用。

using UnityEngine;
using UnityEditor;
using System.Collections;

public class Example : EditorWindow
{
    void OnEnable()
    {
        EditorApplication.contextualPropertyMenu += OnPropertyContextMenu;
    }

    void OnDestroy()
    {
        EditorApplication.contextualPropertyMenu -= OnPropertyContextMenu;
    }

    void OnPropertyContextMenu(GenericMenu menu, SerializedProperty property)
    {
        // show a custom menu item only for Vector3 properties
        if (property.propertyType != SerializedPropertyType.Vector3)
            return;

        // and only when called on a Transform component
        if (property.serializedObject.targetObject.GetType() == typeof(Transform))
            return;

        var propertyCopy = property.Copy();
        menu.AddItem("Randomize Vector", false, () =>
            {
                propertyCopy.vector3Value = Random.insideUnitSphere * 5;
            });
    }
}
