# 字符串转魔兽ID

![](/files/z4AUd4IePJe5qgxzLY4i)

通过 `string.unpack(">I4", "u000")` 可以将字符串 `"u000"` 转换为魔兽整数ID，对应到Jass中的写法是 `'u000'` 。

要注意**单双引号的差别**，以及单双引号在Lua和Jass中**不同的含义**。

也可以使用 `FourCC` 函数来等效替代。

## 原理

魔兽里， `'u000'` 这样的写法实际上对应的是一串整数。\
在Lua中，想要让输入的字符串 `"u000"` 与Jass中的写法 `'u000'` 相同，需要使用 `string.unpack` 函数。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://notebook.lazyknight.com/index/index-2/object-id.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
