ContextMenuItem, ContextMenu, MenuItem区别与联系

ContextMenuItem

用于给成员变量增加右键菜单

加在成员变量上，在成员变量上右键弹出右键菜单，对应的菜单函数只能是成员函数，不能是static函数

public class TestContextMenu : MonoBehaviour
{
    [ContextMenuItem("Reset Count", "CtxtMenuItem_ResetCount")]
    public int m_Count;

#if UNITY_EDITOR

    private void CtxtMenuItem_ResetCount()
    {
        m_Count = 0;
    }

#endif

}

ContextMenu

用于扩展自定组件的Script右键菜单

只能加在成员函数上，加在static函数上没效果

using UnityEngine;

public class TestContextMenu : MonoBehaviour
{
    public int m_Count;

#if UNITY_EDITOR

    [ContextMenu("Another Reset Count")]
    private void CtxtMenu_PrintCount()
    {
        Debug.Log($"m_Count: {m_Count}");
    }

#endif

}

MenuItem

a) 用于扩展内置组件的Script右键菜单

using UnityEditor;
using UnityEngine;

public static class TestMenuItem
{

    [MenuItem("CONTEXT/Transform/Copy Position")]
    static void MenuItem_CopyPosition()
    {
        if (null == Selection.activeTransform) return;
        Vector3 pos = Selection.activeTransform.position;
        Debug.Log($"拷贝的Position为: ({pos.x}, {pos.y}, {pos.z})");
    }

}

b) 用于扩展菜单栏菜单

using UnityEditor;
using UnityEngine;

public static class TestMenuItem
{

    [MenuItem("MyTools/Print Hello")]
    static void MenuItem_PrintHello()
    {
        Debug.Log($"Hello");
    }

}
