1. AbilityType 枚举

架构决策 (2026-05)：改为 [Flags] uint bitmask

原 Dictionary<string, bool> 存档方案每次查询需 .ToString() 装箱 + 字典哈希，在 AbilityGate.Start() 及 ParrySystem.TryActivateParry() 等热路径产生不必要开销

改为 bitmask 后：存档只存一个 uint，查询为单次位运算 (_flags & ability) != 0，兼容序列化

新增能力只需追加新的 1 << N，禁止修改已有枚举值（防止存档数据错位）

本节以当前仓库中的 Assets/Scripts/Player/AbilityType.cs 为准；历史文档中的旧命名不再作为当前实现事实来源

// 路径: Assets/Scripts/Player/AbilityType.cs
// 所有可解锁能力的位标志枚举；PlayerStats.HasAbility() 依赖此
[System.Flags]
public enum AbilityType : uint
{
    None         = 0,

    // 移动能力
    WallCling    = 1u << 0,   // 贴墙悬挂
    WallJump     = 1u << 1,   // 墙跳
    Dash         = 1u << 2,   // 地面冲刺
    AirDash      = 1u << 3,   // 空中冲刺（二段冲刺）
    DoubleJump   = 1u << 4,   // 二段跳
    SuperJump    = 1u << 5,   // 超级跳（聚气跳）
    Swim         = 1u << 6,   // 游泳（液体中自由移动）
    Dive         = 1u << 7,   // 下劈（空中下突）

    // 法术能力
    Spell1       = 1u << 8,   // 法术槽 1（策划自定义）
    Spell2       = 1u << 9,   // 法术槽 2
    Spell3       = 1u << 10,  // 法术槽 3

    // 灵魄形态
    SpiritForm   = 1u << 11,  // 灵魄形态切换
    SpiritDash   = 1u << 12,  // 灵魄冲刺（穿透地形）

    // 战斗能力
    Parry        = 1u << 13,  // 格挡/弹反
    ChargeAttack = 1u << 14,  // 蓄力攻击
    DownSlash    = 1u << 15,  // 下斩

    // 互动能力
    Interact     = 1u << 16,  // 互动（NPC/机关）
    FastTravel   = 1u << 17,  // 快速旅行解锁

    // 组合掩码
    AllMovement  = WallCling | WallJump | Dash | AirDash | DoubleJump | SuperJump | Swim | Dive,
    AllSpells    = Spell1 | Spell2 | Spell3,
    AllSpirit    = SpiritForm | SpiritDash,
}

2. AbilityGate

// 路径: Assets/Scripts/World/AbilityGate.cs
// 物理关卡障碍，阻挡未解锁某能力的玩家
[RequireComponent(typeof(Collider2D))]
public class AbilityGate : MonoBehaviour
{
    [SerializeField] private AbilityType _requiredAbility;
    [SerializeField] private GameObject  _blockingObject;  // 关卡障碍物 GO（禁/启用）
    [SerializeField] private GameObject  _hintUI;          // 提示 UI（如能力图标 + "???"）
    [SerializeField] private string      _gateId;          // 存档用

    [Header("Event Channels")]
    // AbilityTypeEventChannelSO 已在 02_EventSystem §3 定义（替换旧 StringEventChannelSO）
    [SerializeField] private AbilityTypeEventChannelSO _onAbilityUnlocked;  // EVT_AbilityUnlocked

    // _saveData 由 GameInitializer 在 Awake 时注入（零耦合，避免 SaveManager.Instance）
    private SaveData _saveData;

    private void Start()
    {
        // 位运算查询：无需 ToString + 字典哈希
        bool hasAbility = _saveData != null
            && (_saveData.Player.AbilityFlags & (uint)_requiredAbility) != 0;
        _blockingObject.SetActive(!hasAbility);
        if (_hintUI != null) _hintUI.SetActive(!hasAbility);
    }

    private void OnEnable()  => _onAbilityUnlocked.OnEventRaised += OnAbilityUnlocked;
    private void OnDisable() => _onAbilityUnlocked.OnEventRaised -= OnAbilityUnlocked;

    private void OnAbilityUnlocked(AbilityType ability)
    {
        if (ability != _requiredAbility) return;
        _blockingObject.SetActive(false);
        if (_hintUI != null) _hintUI.SetActive(false);
        // P1：播放解锁动画（如荆棘收缩、道路开通特效）
    }

    public void Open() => _blockingObject.SetActive(false);
}

3. 装备系统 — CharmSO

// 路径: Assets/Scripts/Equipment/CharmSO.cs
[CreateAssetMenu(menuName = "Equipment/Charm")]
public class CharmSO : ScriptableObject
{
    [Header("Identity")]
    public string  charmId;        // 全局唯一 ID，如 "Charm_QuickSlash"
    public string  displayNameKey; // 本地化 Key
    [TextArea(2,4)]
    public string  descriptionKey;

    [Header("Visual")]
    public Sprite  icon;
    public Color   glowColor;

    [Header("Slot Cost")]
    [Range(1,4)]
    public int     notchCost;      // 占用笔记数（1~4）

    [Header("Effects")]
    [SerializeReference]
    public List<ICharmEffect> effects;  // 多态序列化（[SerializeReference]）

    [Header("Lore")]
    public bool    isUnique;       // 唯一物品
    public string  unlockHint;
}

资产路径：Assets/ScriptableObjects/Equipment/Charms/
命名：Charm_{Name}.asset

4. ICharmEffect 接口

// 路径: Assets/Scripts/Equipment/ICharmEffect.cs
[System.Serializable]
public interface ICharmEffect
{
    void OnEquip(EquipmentContext ctx);
    void OnUnequip(EquipmentContext ctx);
    string GetEffectDescription();
}

// 上下文：避免接口直接依赖具体类
public struct EquipmentContext
{
    public PlayerStats           Stats;
    public PlayerFeedback        Feedback;
    public EventChannelRegistry  Events;    // SO 事件频道注册表
    public SkillModifierRegistry SkillMods; // 技能修改器注册表
    public WeaponManager         WeaponMgr; // 武器切换管理器
}

4.1 CharmEffectDrawer — 自定义 PropertyDrawer

痛点：Unity 默认的 [SerializeReference] Inspector 体验极差——添加/删除效果需要右键 "Manage References"，类型名显示 C# 全称。策划每日在 CharmSO Inspector 中增减效果，该 Drawer 是必须的。

// 路径: Assets/Scripts/Editor/Equipment/CharmEffectDrawer.cs
// 程序集: BaseGames.Editor（Editor Only）
#if UNITY_EDITOR
using UnityEditor;
using UnityEngine;

namespace BaseGames.Editor.Equipment

    /// - 每条效果展开显示字段 + GetEffectDescription() 预览文字
    /// - 支持拖动重排、单条删除
    /// </summary>
