我当前服务器是MCPC   但mod文件夹是空的   我不想弄mod服  有些插件不支持mcpc 所以我想换成spigot   请问一下 更换后会有哪里不同？比如插件地图一些功能等。求解{:10_492:}

如果没有安装过MOD到是没什么问题，把核心换了直接启动没问题。
如果版本不同那么插件也要更新，但是版本一样的话，没问题。

有人说地图会消失    另外问一句， 中文输入什么的是不是mod呢。。。 换了会不会不能用？

地图会消失有点夸张，其实是别人比如说安装了增加新的方块的MOD，摆到世界里面，换了核心以后没了MOD的支持那些方块就成了BUG 地图会有点报错。你没安装这类型的MOD就没问题。

中文输入有MOD版也有安装到核心版，其实你安装到单机就够了，服务器不用装。

刚刚服务器出了一个错误， 能顺便帮我看看吗？

你的核心为什么还没换？ 换了吧

还没呢，刚刚出这个错误能帮我看一下吗？
