NTAC 是一款为 Spigot 1.9.2 / 1.9.4 服务器设计的反作弊插件，旨在弥补 NoCheatPlus 的不足。它能检测并阻止多种作弊行为，但需要注意的是，NTAC 并未开源，且不再提供更新。此插件需要 Java 8、NTAPI 和 ProtocolLib 4.1+。

如果发现任何错误或绕过方法，请联系作者。如果需要一个完整的反作弊解决方案，建议使用 AAC。

一个小提示：禁用摔落伤害可以修复许多 NC+ 飞行绕过，因为它们需要受到伤害。

❓ 常见问题解答

Q: 应该使用 config.yml 还是 newest-config.yml？

A: 应该使用 config.yml，因为 newest-config.yml 仅用于自动更新 config.yml。（但查看 newest-config 仍然值得，因为它包含注释！）

Q: 如何进行全网络封禁？

A: 内部封禁系统无法做到这一点，但可以使用配置来使用其他封禁系统。

Q: 玩家一击打到动物或生物就会被踢出！

A1: 这是与 ViaVersion 的不兼容问题，请将服务器更新到 Spigot 1.9.4 并使用最新的 ViaVersion 版本。
A2: 如果您没有使用 ViaVersion 或者 A1 没有解决问题，请通过私信联系作者。

Q: 成就不再可用！

A: 禁用 Inv-Walk 功能。
