介紹：
這是一個可以製作特殊箭矢：爆炸箭矢的機關，
將這個機關做出來後，可以將10個火藥和16個箭矢丟於地上可以合成出爆炸箭矢，
接下來就將爆炸箭矢用弓射出，不管命中生物或落於地面都會爆炸，
好好體驗爆炸箭矢的樂趣吧！
我製作的爆炸箭矢不會出現箭矢無法引爆的其他玩家的問題，
以及機關處理上的每個爆炸箭矢都是獨自運行的，輸出指令量也甚少
-----------------------------------------------------------------------------------------------
如何使用機關？
首先先給自己一個指令方塊：
/give @p command_block 1 0
接下來把指令方塊放在地上並打開它，再將下列的指令串貼入，並把指令方塊改成連續執行：
成功後指令方塊上會出現告示牌，右鍵點擊它就可以生成機關：
最後機關就製作完成了：

如果要刪除機關？
在指令召喚出來後機關前面會多出兩個指令方塊，
用按鈕這樣放後按下去即可清除機關：
話說我猜你們會問我為啥不在機關上放可以刪除機關的告示牌：
因為目前用告示牌裡輸出的指令不能再放置一次告示牌，所以只能用另一種方法刪除機關，
為了就是「彩色物品文字」啊！
