Last Epoch是基于Unity和C＃的单人ARPG。游戏具有制作系统-玩家找到修改器，然后将其应用于设备。对于每个修饰符，“不稳定性”会累积，这增加了破坏该项目的机会
我追求两个目标：
- 消除由于应用修饰符而导致的“破损”
- 制作时请勿使用修饰符
这是游戏中制作窗口的样子：
第一部分，我们无需注册和SMS即可编辑.NET代码
首先，我将描述修改游戏旧版本（0.7.8）的过程

实际上，许多流行的语言都被编译成中间代码，由配置文件反编译器很好地解释和修改。对于此类修改，通常的编程技能通常就足够了。
尽管本机二进制文件可能对您的眼睛和大脑造成危险，但结合现代的开放源代码工具进行小幅修改，对程序如何在接近硬件的水平下工作的肤浅了解通常就足够了。
