Minecraft Java Edition – How to Find a Lost Dog

To craft a map from scratch, you need nine sugar cane (every three pieces of sugar cane makes three sheets of paper), four iron ore, fuel to smelt that ore, a piece of Redstone (requires an iron pickaxe or better) and access to a crafting table and furnace.

You can also zoom out the map by adding 8 more pieces of paper and the map itself in a crafting table.

You can also clone the map by adding another empty map with the map you want to clone in the crafting table.

Tags is just a list, [], of strings, "". To add multiple elements to a list, separate them with commas:

/summon Villager ~ ~ ~ {Offers:{},Tags:["extra","CorpFred"],CustomName:"Corporal Frederickson",NoAI:1b}
