Unity实现账号登录，注册功能_unity画布中账号

制作了用户登录界面

 关于弹窗使用了DOTween插件，实现渐隐渐显效果。

关于账号使用了本地Json读取，

默认账号：YSQS/YSQS1

密码：admin/admin1

注册功能其实应该重构的因为有二次读流的问题存在。

账号注册加入了邀请码（其实就一个if)

 接下来就是我那臭死了的源码。

啊，忘了说了还有一个本地时间显示

Time.text = DateTime.Now.Year.ToString() + "年" + DateTime.Now.Month.ToString() + "月" + DateTime.Now.Day.ToString() + "日" +
                  DateTime.Now.Hour.ToString() + ":" + DateTime.Now.Minute.ToString() + ":" + DateTime.Now.Second.ToString();
