Minecraft. Testfor command syntax

minecraft-commandsminecraft-java-editionminecraft-java-edition-server

For example I want find a player with a book that have text: abcdefg
Where should I put NBT data?

/testfor <player> {Inventory:[{id:book_and_quill, damage:<data>s}]}

This is everything I know about detecting something in inventory.

Page data is saved in the pages list. All item data that isn't the root id, Damage, Count, or Slot tags, must be placed within a single tag compound.

As well, when testing for pre-existing data, you must test for it exactly as it's saved. Item IDs are saved with the namespace (defaulting to "minecraft"), so you have to specify that. The correct ID for a book an quill is "minecraft:writable_book". All tags are case-sensitive, so it would be "Damage" rather than "damage", though this value is not used with that item so does not need to be specified.

/testfor @a {Inventory:[{id:"minecraft:writable_book",tag:{pages:["abcdefg"]}}]}

Keep in mind that you cannot specify which page in the book to look at; it will instead look through every element on the target list for a match.

Minecraft – have a testfor command that only teleports a person with a writable_book with a message, and on a certain team

What you are looking for looks something like this:

{Inventory:[{id:minecraft:written_book,tag:{pages:[0:"\"Test\""]}}]}

But the teleport command does not support NBT tags. However, there is a workaround using scoreboards.

First add a scoreboard objective:

/scoreboard objectives add HoldingBook dummy HoldingBook

Then run these 2 commands on a fast clock:

/scoreboard players set @a HoldingBook 2 {Inventory:[{id:minecraft:written_book,tag:{pages:[0:"\"Test\""]}}]}
/scoreboard players remove @a HoldingBook 1

Now, you can teleport the players holing a written book with the word "Test" on the first page, and for example on team blue;

/tp @a[score_holdingbook_min=1,team=blue] <your-coords>

Hope this helps.

Minecraft – Testfor from player

While you cannot use testfor to do this, you CAN use execute detect. This is most likely how it would look: /execute @a ~ ~ ~ detect ~1 ~ ~ grass 0 <command>

the execute command will detect a grass block to the left (in the X cord) of all players in the world. the command is how you would track that player if it detects the block successfully.

an example tracking command would be /execute @a ~ ~ ~ detect ~1 ~ ~ grass 0 scoreboard players set @p Sample_Obj 1

comment if you have any other questions.
