User:Armelidy/使用U盘游玩Minecraft

为了更方便地游玩游戏，可以将游戏存放在一个可移动磁盘，即U盘内，并只需要插入任意一台计算机便可以立马启动。本教程将讲述如何使用U盘游玩Minecraft（Use portable disk to launch Minecraft）。

配置要求

性能良好的可移动磁盘，存储空间至少8GB。若想安装更多的游戏版本以及存放存档，可能还需要更大的空间。

对于作为游玩游戏时的计算机，详见mcwzh:Java版#硬件需求。

下载所需文件

启动器

此处使用Hello Minecraft! Launcher作为启动器，可以在此下载。需要一个.jar文件的HMCL，而不是.exe为后缀名的文件。正式版和开发版均可使用。

Java运行时环境

不同版本的游戏对JRE的版本也有要求。例如：从1.12开始需要Java 8；1.18以后需要Java 17。具体在mcwzh:Java版#软件需求查看。

能获取JRE的网站有：

• Bellsoft：bell-sw.com
• Oracle：www.oracle.com

配置文件

新建一个文件夹，命名为任意一个名字，所在的目录和其文件夹名最好只包含字母、数字和下划线。这个文件夹会在下文称作游戏目录。

将HMCL移动到游戏目录下。并把下载到的JRE安装程序（.msi或.exe）打开，设置安装目录为游戏目录，有多个需要的Java版本就分开安装。如果JRE是一个压缩包，则解压至游戏目录。

HHML

在下方下载HHML，有中文和英文两种语言。也可以直接复制下方代码到记事本程序中，保存为后缀名.bat，解码为ANSI的脚本文件。英文版相对稳定一些，若中文版出现文字乱码，请用英文版。TODO...

自制脚本

自制脚本不如上文的好用，JRE目录有更改时需要手动编辑，但更简洁。

打开记事本程序，输入：

<Java文件夹名>\bin\java.exe -jar <HMCL文件名>

保存为.bat文件，文件名任意，但编码格式必须为ANSI。

如果在启动器关闭后还想浏览启动器日志，可以在新的一行加上pause。
