展开《我的世界》铺铁轨一支是一个让人心烦的事情，辛辛苦苦挖到铁做出了铁轨还要一个一个的铺，很多玩家都觉得很累，下面小编交给大家一个方法，让你再也不用为铺铁轨累而担忧。
先放一个命令方块,命令方块上放一个按钮
稍稍受咋啮，一毛不得留。
命令方块代码：
/summon MinecartCommandBlock ~-1 ~ ~ {Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Command:"/setblock ~-1 ~1 ~ 0 0 destroy"},Command:"/setblock ~-1 ~ ~ 0 0 destroy"},Command:"/setblock ~-1 ~-2 ~ 152 0 replace"},Command:"/setblock ~-1 ~-1 ~ 157 0 replace"}
在命令方块的W方向 放一块红石,红石上方放一个激活铁轨
再右击按钮激活命令方块
激活后会出现命令矿车,推一下命令矿车试试
4个方向不同的代码(往哪个方向挖就用哪个方向的代码)：
W方向：
/summon MinecartCommandBlock ~-1 ~ ~ {Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Command:"/setblock ~-1 ~1 ~ 0 0 destroy"},Command:"/setblock ~-1 ~ ~ 0 0 destroy"},Command:"/setblock ~-1 ~-2 ~ 152 0 replace"},Command:"/setblock ~-1 ~-1 ~ 157 0 replace"}
S方向：
/summon MinecartCommandBlock ~ ~ ~1 {Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Command:"/setblock ~ ~1 ~1 0 0 destroy"},Command:"/setblock ~ ~ ~1 0 0 destroy"},Command:"/setblock ~ ~-2 ~1 152 0 replace"},Command:"/setblock ~ ~-1 ~1 157 0 replace"}
E方向：
/summon MinecartCommandBlock ~1 ~ ~ {Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Command:"/setblock ~1 ~1 ~ 0 0 destroy"},Command:"/setblock ~1 ~ ~ 0 0 destroy"},Command:"/setblock ~1 ~-2 ~ 152 0 replace"},Command:"/setblock ~1 ~-1 ~ 157 0 replace"}
N方向：
/summon MinecartCommandBlock ~ ~ ~-1 {Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Riding:{id:"MinecartCommandBlock",Command:"/setblock ~ ~1 ~-1 0 0 destroy"},Command:"/setblock ~ ~ ~-1 0 0 destroy"},Command:"/setblock ~ ~-2 ~-1 152 0 replace"},Command:"/setblock ~ ~-1 ~-1 157 0 replace"}
