Unity编辑器扩展秘籍-利用EditorApplication.contextualPropertyMenu为右键菜单增加自定义菜单选项

假设我们希望为材质右键弹出按钮增加新的功能，应该怎么做呢

我们可以通过注册EditorApplication.contextualPropertyMenu全局回调方法，增加自定义的MenuItem

Copy

using UnityEditor;
using UnityEngine;

namespace Yaojz
{
    [InitializeOnLoad]
    public static class MaterialContextMenuCopy
    {
        static MaterialContextMenuCopy()
        {
            EditorApplication.contextualPropertyMenu += OnPropertyContextMenu;
        }

        private static void OnPropertyContextMenu(GenericMenu menu, SerializedProperty property)
        {
            if (property.objectReferenceValue == null)
            {
                return;
            }
            var objValue = property.objectReferenceValue;
            var type = objValue.GetType();
            //这里判断是否是特定类型
            if (type == typeof(Mesh))
            {
                menu.AddItem(new GUIContent("复制并引用"),false, () =>
                {
                    
                });
            }
            else if (type == typeof(Material))
            {
                menu.AddItem(new GUIContent("复制并引用"),false, () =>
                {
                        
                });
            }
        }
    }
}
