python也能开发minecraft启动器
最近我在csdn上看见了 __小小的程序员__ 博主的文章，发现python可以开发minecraft启动器？
好牛皮！我试了一下！果真可以，所有版本（包括最新1.19和最新快照）都可以。别忘了pip install pyqt5和minecraft-launcher-lib哦
效果：
选择路径，颜色界面
选择版本和启动游戏界面
版本安装界面
下载地址：
github链接
gitee链接
希望此文对你有帮助。
这一个程序可以自己下载minecraft java edition（包括beta版本，远古版！），如果可以自己改动代码的话首先要下载qt designer，这是python里pyqt里面的一个图形化界面设计应用。
关键的是，下载这些东西都可以不用钱了！动了小心思。
提醒：大家不要沉迷哦

截图：（没有骗你，是java版本，下载下来的，不是launcher或者其他地方的图片）
是不是很nice？这就是java版本。和原版一点也没有区别！
