1、问题一：如何给命令方块
①拿出一个命令方块，在里面输入/summon Villager ~ ~1 ~ {Profession:1}，然后用红石激活。这样就可以获得一个村民。
②拿出命令方块输入代码，buy是玩家给村民的物品，sell是村民卖给玩家的物品。
③最后，根据自己需要进行交换即可。
2、交易的物品名称
交易的时候使用的命令代码：
/summon Villager ~ ~1 ~
{Offers:{Recipes:[{maxUses:9999999,buy:{id:264,Count:1},sell:{id:267,Count:1}}]}}
中的id就是物品ID，对应物品的名称和ID可以用tmi看，或者百度搜索 “我的世界物品ID大全”，以下为部分物品名称：

扩展资料
命令代码说明
1、获取村民代码：/summon Villager ~ ~1 ~ {Profession:1}
prpfession后面的数字表示村民的ID，可以进行替换，村民ID列表：
0 - 农民
1 - 图书管理员
2 - 神父
3 - 铁匠
4 - 屠夫
5 - 特殊绿色外套村民
2、交易代码：
/summon Villager ~ ~1 ~
{Offers:{Recipes:[{maxUses:9999999,buy:{id:264,Count:1},sell:{id:267,Count:1}}]}}
maxUses：填村民要交易的次数，填1就代表一次，交易完了就没了，可以填999999，接近无限交易。
buy：玩家给村民的物品。id是物品ID。
Count：是物品数量，填64就是给村民1组。
sell：村民卖给玩家的物品，后面也是ID和数量。
