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:

python也能开发minecraft启动器_第1张图片 选择路径,颜色界面
python也能开发minecraft启动器_第2张图片 选择版本和启动游戏界面
python也能开发minecraft启动器_第3张图片 版本安装界面

 下载地址:

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

功能:

改变界面颜色,文件路径,下载版本,启动游戏


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)

python也能开发minecraft启动器_第4张图片

 是不是很nice?这就是java版本。和原版一点也没有区别!
