+# PHY 编辑器打通清单（装备/药品/通知）
+
+> 目标：打通你当前 C++ 已实现的链路：
+> - 装备穿脱 -> 属性生效/回滚
+> - 药品使用（Server RPC）-> 扣除库存 -> 恢复属性
+> - 通知飘字（Info/Reward/Warning）
+
+## 0. 代码前提（已实现）
+
+- `APHYCharacter` 已挂载：`InventorySystem` + `EquipmentSystem`。
+- 服务器 `BeginPlay` 会初始化库存与装备系统。
+- `APHYPlayerCharacter::ServerUseConsumableByItemId` 已有严格校验：
+  - 必须是 `GIS.Item.Type.Consumable`
+  - 找不到道具/扣除失败会发 Warning 通知
+- `APHYPlayerState` 已接入 owner 通知分发（支持 DS/Listen/Standalone）。
+
+## 1. GameplayTags（必须先做）
+
+请在 `Project Settings -> Gameplay Tags` 或 `Config/DefaultGameplayTags.ini` 中确认存在：
+
+### 1.1 类型标签（必须）
+
+- `GIS.Item.Type.Weapon`
+- `GIS.Item.Type.Equipment`
+- `GIS.Item.Type.Consumable`
+- `GIS.Item.Type.Material`
+
+### 1.2 药品效果标签（必须）
+
+- `GIS.Attribute.Item.Consumable.RestoreHealth`
+- `GIS.Attribute.Item.Consumable.RestoreInnerPower`
+
+### 1.3 装备属性标签（建议）
+
+- `GIS.Attribute.Item.Attack`
+- `GIS.Attribute.Item.Defense`
+- `GIS.Attribute.Item.CritRate`
+- `GIS.Attribute.Item.CritDamage`
+- `GIS.Attribute.Item.Hit`
+- `GIS.Attribute.Item.Dodge`
+- `GIS.Attribute.Item.Parry`
+- `GIS.Attribute.Item.CounterChance`
+- `GIS.Attribute.Item.ArmorPenetration`
+- `GIS.Attribute.Item.DamageReduction`
+- `GIS.Attribute.Item.LifeSteal`
+- `GIS.Attribute.Item.Resilience`
+- `GIS.Attribute.Item.MoveSpeed`
+- `GIS.Attribute.Item.HealthRegenRate`
+- `GIS.Attribute.Item.InnerPowerRegenRate`
+- `GIS.Attribute.Item.MaxHealth`
+- `GIS.Attribute.Item.MaxInnerPower`
+
+## 2. 角色蓝图组件配置
+
+打开你的玩家角色蓝图（继承 `APHYPlayerCharacter`）：
+
+1. 选中 `InventorySystem` 组件：
+   - 确认存在普通背包集合（如 `GIS.Collection.Inventory`）
+   - 确认存在装备槽集合（如 `GIS.Collection.Equipped`，SlotCollection）
+2. 选中 `EquipmentSystem` 组件：
+   - `TargetCollectionTag` 设为装备槽集合标签（如 `GIS.Collection.Equipped`）
+
+> 若 `TargetCollectionTag` 不匹配，装备状态事件不会触发，属性不会生效。
+
+## 3. 创建三类物品（UGIS_ItemDefinition）
+
+## 3.1 药品示例：`ID_Cons_HealthSmall`
+
+- `DisplayName`: 小还丹
+- `ItemTags`: 添加 `GIS.Item.Type.Consumable`
+- 图标：设置 `Icon`
+- 动态或静态属性至少配置其一：
+  - `GIS.Attribute.Item.Consumable.RestoreHealth = 120`
+  - `GIS.Attribute.Item.Consumable.RestoreInnerPower = 0`
+
+## 3.2 武器示例：`ID_Wpn_BronzeSword`
+
+- `DisplayName`: 青铜剑
+- `ItemTags`: 添加 `GIS.Item.Type.Weapon`
+- 属性：
+  - `GIS.Attribute.Item.Attack = 35`
+  - `GIS.Attribute.Item.CritRate = 0.03`
+
+## 3.3 装备示例：`ID_Equip_ClothArmor`
+
+- `DisplayName`: 布甲
+- `ItemTags`: 添加 `GIS.Item.Type.Equipment`
+- 属性：
+  - `GIS.Attribute.Item.Defense = 20`
+  - `GIS.Attribute.Item.DamageReduction = 0.02`
+
+## 4. 物品“使用”按钮绑定（UI）
+
+在你的物品操作逻辑中（右键菜单/快捷键）：
+
+1. 从 `UItemData` 取 `ItemInfo.Item`
+2. `Item->GetItemId()` 拿到 `FGuid`
+3. `GetOwningPlayerPawn` -> Cast `APHYPlayerCharacter`
+4. 调用：`ServerUseConsumableByItemId(ItemId, 1)`
+
+## 5. 通知验证点
+
+你当前 UI 会接 `OnGameplayNotifyDelegate`，预期：
+
+- 使用药品成功：`Reward`（例如：使用 小还丹 x1）
+- 使用非药品：`Warning`
+- 数量不足/扣除失败：`Warning`
+- 装备成功：`Info`（装备 xxx）
+- 卸下成功：`Info`（卸下 xxx）
+
+## 6. 联机验收顺序（建议）
+
+1. Standalone
+2. Listen Server + 1 Client
+3. Dedicated Server + 1 Client
+
+每轮都检查：
+
+- 药品是否扣库存
+- 生命/内力是否恢复
+- 装备/卸下是否改变属性
+- 通知是否只在拥有者客户端显示
+
+## 7. 常见问题
+
+- **现象：药品点了无反应**
+  - 常见原因：缺少 `GIS.Item.Type.Consumable`
+- **现象：装备后属性不变**
+  - 常见原因：`EquipmentSystem.TargetCollectionTag` 不匹配装备集合
+- **现象：Dedicated Server 下无提示**
+  - 先确认 HUD/UI 绑定是否在客户端建立；`PlayerState` 已支持 owner 通知分发
+
+---
+
+如果你需要，我可以继续生成第二份文档：
+- `PHY_Item_Asset_Convention.md`（命名规范 + 品质色 + 图标规范 + 掉落表字段模板）
+

+# PHY Item Attribute System (GIS)
+
+## 本次新增
+
+- `Source/PHYInventory/Private/GameplayTags/PHYInventoryItemTags.h`
+- `Source/PHYInventory/Private/GameplayTags/PHYInventoryItemTags.cpp`
+- `Source/PHYInventory/Private/Items/PHYItemFragment_PropertySet.h`
+- `Source/PHYInventory/Private/Items/PHYItemFragment_PropertySet.cpp`
+- `Source/PHYInventory/Private/Items/PHYItemBlueprintLibrary.h`

+- `Source/PHY/Private/Character/PHYPlayerCharacter.cpp`
+- `Source/PHY/Private/Gameplay/Player/PHYPlayerState.h`
+- `Source/PHY/Private/Gameplay/Player/PHYPlayerState.cpp`
+
+## 新增联动能力（12）
+
+### 1) 装备属性自动生效/回滚（服务器权威）
+
+- 在基础角色上新增 `UGIS_EquipmentSystemComponent`。
+- 服务器 `BeginPlay` 时：先初始化 `InventorySystem`，再初始化 `EquipmentSystem`。
+- `APHYPlayerCharacter` 监听 `OnEquipmentStateChangedEvent`。
+- 事件触发后通过 `APHYPlayerState::HandleItemEquippedState` 应用或回滚属性。
+- 使用 `AppliedEquipmentItems` 防止同一个 ItemId 重复叠加。
+
+### 2) 药品 Server RPC 使用链路
+
+- 在 `APHYPlayerCharacter` 新增：
+  - `UFUNCTION(Server, Reliable) ServerUseConsumableByItemId(FGuid ItemId, int32 Count=1)`
+- 服务端流程：
+  - 按 `ItemId` 在库存中查找道具
+  - 扣减库存数量（`RemoveItem`）
+  - 调用 `APHYPlayerState::ApplyConsumableFromItem` 应用恢复
+- 当前默认读取道具动态属性标签：
+  - `GIS.Attribute.Item.Consumable.RestoreHealth`
+  - `GIS.Attribute.Item.Consumable.RestoreInnerPower`
+
+## 设计
+
+- 基于 GIS 的 `UGIS_ItemDefinition` + Fragment。
+- 新增 `UPHYItemFragment_PropertySet` 作为统一“武器/装备/药品”属性片段。
+- 道具实例创建时会把 `BaseFloatModifiers` / `BaseIntegerModifiers` 写入 `UGIS_ItemInstance` 动态属性。
+
+## 主要能力
+
+- 统一道具大类：`EPHYItemArchetype`
+  - `Weapon`
+  - `Equipment`
+  - `Consumable`
+  - `Material`
+  - `Quest`
+- 统一装备槽：`EPHYEquipSlotType`
+- 药品效果载荷：`FPHYConsumablePayload`
+  - `RestoreHealth`
+  - `RestoreInnerPower`
+  - `DurationSeconds`
+
+## GameplayTags 管理
+
+标签已集中在 `Source/PHYInventory/Private/GameplayTags/PHYInventoryItemTags.*`，避免代码中散落字符串：
+
+- `GIS.Item.Type.Weapon`
+- `GIS.Item.Type.Equipment`
+- `GIS.Item.Type.Consumable`
+- `GIS.Item.EquipSlot.MainHand` 等
+- `GIS.Attribute.Item.Attack`、`GIS.Attribute.Item.CritRate` 等
+
+## 如何创建三类物品
+
+1. 在编辑器创建 `UGIS_ItemDefinition` 资产。
+2. 给该资产添加 Fragment：`PHY Item Property Settings`。
+3. 按类型配置：
+   - 武器：`ItemArchetype=Weapon`，`EquipSlot=MainHand/OffHand`，填写攻击/暴击等属性。
+   - 装备：`ItemArchetype=Equipment`，设置对应 `EquipSlot`，填写防御/免伤/韧性等属性。
+   - 药品：`ItemArchetype=Consumable`，填写 `ConsumablePayload`（回血/回内力）。
+4. 把物品加入你的掉落表/默认背包配置。
+
+## 蓝图辅助
+
+`UPHYItemBlueprintLibrary` 提供：
+
+- `GetItemArchetype`
+- `GetEquipSlotType`
+- `IsWeaponItem`
+- `IsEquipmentItem`
+- `IsConsumableItem`
+- `GetConsumablePayload`
+
+用于 UI 显示和使用逻辑分流。
+
+## 备注
+
+- 当前为 MVP：先打通类型与属性承载。
+- 下一步可扩展：随机词条（Roll）、品质颜色、套装、与 GAS GameplayEffect 自动联动。
