前言

       解压怀旧一下mc，打造一个全自动化世界。期间，做了很多自动化逻辑流程设计、查修一些bug反馈到github修正，手工开发一些function补充功能，自编译mod提前修已知问题等，基本没有娱乐，主要在研究和创造，过程不亚于工作中的开发。

       结果很不错，这里分享一些难点解决。

一、问题背景

       mc 全自动化实现，电孤炉不能更换石墨电极，批量生产更换频率不低，有待解决。

       环境：mc1.16.3，forge，沉浸工程  植物魔法 精致存储等

       解决之后，积压的数万矿石不到1天就消化了，效率不错。

二、方案

        最简单的办法是基于别人的mod开发一个mod，新版开发环境还得构造，没时间，网也q了。这里分享一个基于官方机制，添加一个数据包(datapack)来解决。

三、datapack使用介绍

      略，见https://minecraft-zh.gamepedia.com/%E6%95%B0%E6%8D%AE%E5%8C%85，假设你已经了解如何添加1个数据包并生效一个函数。

四、先上效果

 使用布局如图，另一张是供物料特写

五、实现原理

1. 核心：在电孤炉电极外观上放置一个命令方块执行新增加的函数ie_auto_electrode。代码写死了下向5格就是电孤炉的中心。
2. 外围：放置一个定时器定时触发红石信号驱动。这里用了植物魔法的沙漏，也可以用原版红石中继器实现。
3. 外围：附件放置一个自动放置石墨电极物品的装置，基本原理很简单，抛下一个物品，触发压力板，再反向控制不再放置物品。这里上面用于了植物魔法花格箱以解决准度，原版投掷器也可以。

     核心逻辑：

     1、创建2个积分板用于存储中间数据和状态。

     2、环境检测，确保下方是电孤炉，附件有满耐久的石墨电极。

     3、检测电弧炉23-25号slot nbt数据，检测是否有电极缺失或损坏值大于95550（96000最大）。

     4、如有，进行更换或恢复耐久，清除1个满耐久电极。

     5、执行1次替换就设置了结束状态。全部替换需要反复执行完成。

六、代码

细节暂不解释，有用直接复制走即可，有兴趣可以交流。
