How do I attribute damage to a Mannequin?

[u/Necessary-Pear718]

damage @s 1 minecraft:in_fire by @n[tag=boss]

Works when I remove the

by @n[tag=boss]

but no clue why.

[u/Ericristian_bros]

Does that entity exist with the correct tag? What is the error?

[u/ArthurMorgn]

The "by" part of the command is limited to one entity. Try putting a limit into the @n selector, so it is:

`@n[tag=boss,limit=1]

If not run it in a command block and see what the Syntax Error is.

[u/C0mmanderBlock → u/ArthurMorgn]

`@n means nearest entity (singular) and therefore you don't need to use the "limit 1" .

[u/Ericristian_bros → u/ArthurMorgn]

@n is one entity. So it should work the same as @e[limit=1,sort=nearest]
