交互式小说中随机查阅书籍主题的代码报错问题求助

核心问题分析 #

你遇到的your former self是Inform7运行时的误导性报错文本，实际问题是错误地将table name属性当作实际表来操作。table name只是存储了表的标识符，并非表本身，直接对它调用表相关操作（比如number of rows）会触发属性访问错误。

修正方案 #

要通过table name属性访问实际表，必须使用the table of [表名属性]的语法，将属性中存储的表标识符转换为可操作的表对象。同时建议避免用contents作为自定义属性名（虽然你已经改了ToC，但这个习惯能减少内置属性冲突）。

完整修正代码 #

1. 定义书的类型和表名属性：

A book is a kind of thing. A book has a table name called ToC.

2. 定义书籍对应的内容表（以《Costa Rican Ornithology》为例）：

Table of Costa Rican Birds
Topic               Reply
"quetzal"           "Resplendent quetzals are famous for their iridescent green tail feathers, and are considered a symbol of Costa Rica's biodiversity."
"toucan"            "Keel-billed toucans use their large, colorful bills to reach fruit on thin branches, and their bills are surprisingly light due to a honeycomb structure."
"hummingbird"       "Rufous-tailed hummingbirds are common in lowland forests, feeding on nectar and small insects. They can beat their wings up to 80 times per second."

3. 给具体书籍绑定对应表：

The Costa Rican Ornithology is a book in the Library. The ToC of Costa Rican Ornithology is the Table of Costa Rican Birds.

4. 修正随机翻阅的动作逻辑：

Understand "consult [a book]" as consulting vaguely.

Consulting vaguely is an action applying to one visible thing.

Carry out consulting vaguely:
    let target-book be the noun;
    let target-table be the table of ToC of target-book;
    choose a random row in target-table;
    say "[reply entry][paragraph break]".

额外说明 #

如果你想保留分步计算行数和随机行的逻辑，也可以改成：

Carry out consulting vaguely:
    let target-book be the noun;
    let target-table be the table of ToC of target-book;
    let row-count be the number of rows in target-table;
    let random-row-number be a random number from 1 to row-count;
    choose row random-row-number in target-table;
    say "[reply entry][paragraph break]".

关键是必须通过the table of ToC of target-book获取实际的表对象，而不是直接使用ToC of target-book。
