Tutorial:Useful commands

These features are primarily exclusive to Java Edition.

Commands are useful for map building, Creative mode, etc. The ones described on this page are useful for building an adventure map, testing mechanics and commands, or just for pure fun.

Invisible Item Frame

Item Frame is an entity. We can get an invisible item frame using /give command. This is the command:

/give @p minecraft:item_frame[minecraft:entity_data={id:"item_frame",Invisible:1b}]

Villager Trades

Villagers are passive mobs and they live in villages. We can trade with them. By using a /summon command, we can spawn villagers with custom trades.

/summon villager ~ ~1 ~ {VillagerData:{profession:farmer,level:2,type:plains},CustomName:"\"John\"",Offers:{Recipes:[{buy:{id:emerald,Count:1},sell:{id:wheat,Count:1},rewardExp:0b,maxUses:9999999}]}}

This command will spawn a villager named "John" who sells 1 wheat for 1 emerald.

Profession and types

You can edit the profession:farmer to other professions, type:plains to specific biomes. You can see all the professions and types at here.

Custom name

You can change CustomName to any name.

Id and count

Change the id to any items or blocks. Count defines the number of items.

Reward experience and max uses

rewardExp is the experience you get when you traded. maxUses is how many times you can trade with.

Replacing Blocks

By using /fill command, you can replace a type of block in an area.

/fill 16 ~ 16 0 ~ 0 minecraft:stone replace minecraft:grass_block

The command above will replace all grass blocks to stone in an area. The 16 ~ 16 0 ~ 0 are the coordinates. The block after replace is the block we want to replace.

Custom Enchantment Levels

By using /give command, we can get an item, such as netherite sword, with a custom level of any enchantment, such as sharpness.

Single enchantment

/give @p minecraft:netherite_sword[minecraft:enchantments={sharpness:10}] 1

The command above will give you a netherite sword with Sharpness 10. You will see the enchantment as Sharpness X. You can change the id to any enchantment.

Multiple enchantments

To get more than one enchantment on a tool or weapon, add a comma after the first enchantment and add a new one.

/give @p minecraft:netherite_sword[minecraft:enchantments={sharpness:10,looting:10}] 1

This command added Sharpness 10 and Looting 10 to a netherite sword.

Levels

Change sharpness to any number. The maximum number is 255, if your number is bigger than 255, the level will automatically change to 255.

Death Scoreboard

Map builders sometimes use a death scoreboard in a parkour map. You can use /scoreboard to do it.

Creating scoreboard

This creates a death scoreboard. The Deaths in the command is the name of scoreboard, that means you can change it to any words.
