模块:UnlockBook

概述

UnlockBook 提供解锁类书本条目的数据读取与展示辅助，供 Template:Infobox unlockbook 调用。

当前数据来自 `数据:UnlockBook/unlockbook_index.json` 与 `数据:UnlockBook/unlockbook_target_index.json` 两页，后者用于去重解锁目标，控制单页大小。

用法

读取字段：

• {{#invoke:UnlockBook|getField|西番柿炖牛脯食谱|type_display}}

渲染主解锁对象：

• {{#invoke:UnlockBook|targetSummary|西番柿炖牛脯食谱}}

渲染完整解锁清单：

• {{#invoke:UnlockBook|targetList|基础建造手册}}

渲染对应设备：

• {{#invoke:UnlockBook|stationList|弓箭包}}

主要函数

• getField：读取基础字段。
• targetSummary：渲染主解锁对象摘要。
• targetList：渲染完整解锁清单。
• stationList：渲染对应设备列表。
