模块:Shop

模板:Documentation subpage Shop 提供商店库存、物品反查与商店元数据读取能力，供 Template:SoldBy、Template:ShopInventory 和 Template:Infobox building 调用。

示例

• {{#invoke:Shop|renderSoldBy|土豆种子}}
• {{#invoke:Shop|renderShopInventory|肥记早餐店}}
• {{#invoke:Shop|getShopField|Shop.BreakfastCar|open_duration}}
• {{#invoke:Shop|getShopField|Shop.Grocery|currency_summary}}

导出函数

• renderSoldBy：渲染物品页的商店出售反查表。
• renderShopInventory：渲染商店库存表。
• getShopField：获取商店元数据字段与页面级计算字段。

展示规则

• 金币 / 星砂 / 经验会优先转成 {{Gold}} / {{Star}} / {{Exp}}。
• 商店库存页会按较宽的物品大类分组，并在每组前输出小标题。
• 组内条目会按“大类 -> 物品类型 -> 分类语义 -> 条件层级 -> 物品系列 / 等级”稳定排序。
• 条件层级默认是“无条件 -> 普通条件 -> 称号等级 -> 任务 / 特殊条件”。
• 当某一组条目共享同一刷新周期时，`限购` 与 `刷新` 会自动合并成更紧凑的 `购买限制`。

字段

• name
• description
• map_description
• kind
• open_duration
• shop_template
• festival_template
• location_names
• area_ids
• sources
• entries

计算字段

• kind_display
• source_display
• location_display
• area_ids_display
• area_count
• template_refs_display
• entry_count
• currency_summary
• auto_categories
