### 对于 进度条自定义 功能的说明
因为我们提供了可以自动转换进度条的功能,因此在这里给出进度条自定义参数的详细解释。
一个进度条,明显地,有**固定部分**和**可变部分**来构成。而可变部分又包括了文字和图形两种(当然,《我的世界》里头的进度条,可变的图形也就是那个“条”了)。这一点你需要了解,因为后文中包含了很多这方面的概念需要你了解。
进度条的自定义功能使用一个字符串来定义自己的样式,其中包含众多**标识符**来表示可变部分。
标识符如下(注意大小写):
| 标识符 | 指定的可变量 |
|---------|----------------|
| `%%N` | 乐曲名(即传入的文件名)|
| `%%s` | 当前计分板值 |
| `%^s` | 计分板最大值 |
| `%%t` | 当前播放时间 |
| `%^t` | 曲目总时长 |
| `%%%` | 当前进度比率 |
| `_` | 用以表示进度条占位|
表示进度条占位的 `_` 是用来标识你的进度条的。也就是可变部分的唯一的图形部分。
**样式定义字符串**的样例如下,这也是默认的进度条的样式:
`▶ %%N [ %%s/%^s %%% __________ %%t|%^t]`
这是单独一行的进度条,当然你也可以制作多行的,如果是一行的,输出时所使用的指令便是 `title`,而如果是多行的话,输出就会用 `titleraw` 作为进度条字幕。
哦对了,上面的只不过是样式定义,同时还需要定义的是可变图形的部分,也就是进度条上那个真正的“条”。
对于这个我们就采用了固定参数的方法,对于一个进度条,无非就是“已经播放过的”和“没播放过的”两种形态,所以,使用一个元组来传入这两个参数就是最简单的了。元组的格式也很简单:`(str: 播放过的部分长啥样, str: 没播放过的部分长啥样)` 。例如,我们默认的进度“条”的定义是这样的:
`('§e=§r', '§7=§r')`
综合起来,把这些参数传给函数需要一个参数整合,你猜用的啥?啊对对对,我用的还是元组!
我们的默认定义参数如下:
`(r'▶ %%N [ %%s/%^s %%% __________ %%t|%^t]',('§e=§r', '§7=§r'))`
*对了!为了避免生成错误,请尽量避免使用标识符作为定义样式字符串的其他部分*

### Instructions for **Customize Progress Bar**
We have supported the function of making progress bar in *Minecraft*'s music player. And also the method of customize them. So the following instructions are about the parameters of the Progress Bar Customizition.
A Progress Bar, of course, is composed of **changeless** parts and **changable** parts. And the changable parts include texts or *images*(these images are made up of texts, or we can say, character paintings 😁). That is, for *Minecraft*, a changable image in a progress bar is just the "bar" part(which is like a stripe).
We use a string to describe the style of progress bar you need, and it includes many **identifier**s to replace the changable parts.
There are the identifiers:
| Identifier | Changable Part |
|--------------|------------------------------------------------------|
| `%%N` | Music name(file name which is imported into program) |
| `%%s` | Value of scoreboard of now |
| `%^s` | Max value of scoreboard |
| `%%t` | Current playback time |
| `%^t` | Total music time |
| `%%%` | Current playback progress |
| `_` | To be replaced by the *Bar* part of the progress bar |
The `_` is a placeholder to identifying the *bar* part, yeah, just the changable image.
This is an example of **style description string**, and this is also the default style of *Musicreater*'s progress bar.
`▶ %%N [ %%s/%^s %%% __________ %%t|%^t]`
This is a progress bar with only one line, but it is possible if you want to give a multiline parameter into the style description string.
But the string above is only for style identification, but we also need to identifying the changable image's image(just what the bar's look).
A "bar", simply, included 2 parts: *Have Been Played* & *Not Been Played*. So we use a tuple to pass the parameter. It's under a simple format: `(str: played, str: not)`. For example, the default parameter is below:
`('§e=§r', '§7=§r')`
So it's time to combine what I said in one parameter now!
This is a default definder parameter:
`('▶ %%N [ %%s/%^s %%% __________ %%t|%^t]',('§e=§r', '§7=§r'))`
*Tip: To avoid errors, please not to use the identifiers as the other part of your style.*
