Inform7技术问题：如何让NPC收到物品后执行检视动作

你遇到的核心问题是自定义的After giving规则没有触发NPC的检视动作，连报告规则都没响应——这大概率是规则优先级或者动作触发条件的问题。下面是一步步的排查和修复方案：

1. 提升规则优先级，避免被默认规则覆盖 #

Inform 7的规则系统会按优先级执行，默认的After giving规则可能会抢先覆盖你的自定义逻辑。你可以用Last after强制让你的规则最后执行，确保它能生效：

Last after giving the book to Tom:
    try Tom examining the book.

2. 确保物品已成功转移到NPC手中 #

虽然After giving理论上是在物品转移完成后触发，但特殊场景下可能存在物品未及时归属NPC的情况。你可以添加条件，确保动作只在Tom真正拿到书后触发：

Last after giving the book to Tom when the book is carried by Tom:
    try Tom examining the book.

3. 用force跳过动作检查（如果try失效） #

默认的try会触发动作的Check规则，可能某些隐形限制（比如NPC默认不会主动执行动作的隐含逻辑）阻止了检视动作。这时候可以用force跳过所有检查，直接强制执行：

Last after giving the book to Tom:
    force Tom to examine the book;

4. 修正报告规则的匹配范围 #

确保你的报告规则能准确匹配场景，避免因语法限制导致不触发：

Report Tom examining the book:
    say "Tom takes the book, flips through its pages, and mutters, 'Interesting...'.";

完整可运行示例 #

把这些逻辑整合起来，完整代码如下：

The Library is a room.

Tom is a man in the Library.

The tattered book is a thing. It is carried by the player.

Last after giving the tattered book to Tom when the tattered book is carried by Tom:
    force Tom to examine the tattered book;

Report Tom examining the tattered book:
    say "Tom takes the tattered book, runs a finger over its cover, and starts flipping through the pages slowly.";

测试时输入give book to Tom，就会先显示默认的交付文本，紧接着触发Tom的检视动作并输出你自定义的报告内容。
