Using a curly bracket inside a command

[simonfruehauf]

Using a { or } inside a command, e.g. entitydata @e[type=minecraft:creeper,distance=..1] {NoAI:1} does not successfully execute. The error logged is Caused by: java.lang.RuntimeException: Attempt to access undefined local 'NoAI:1"'!. It seems that curly brackets inside quotation marks do not get escaped correctly, even if using a .

You can use a backslash ( \, written in configs as \\) to escape the leading curly bracket.

So your command should look like this: entitydata @e[type=minecraft:creeper,distance=..1] \\{NoAI:1}

In case that doesn't help, try a single backslash: entitydata @e[type=minecraft:creeper,distance=..1] \{NoAI:1}

The first solution (\\) gives me a console error , the second one (\) a chat error .

EDIT: nevermind, it worked after restarting the server a couple times.

I've been trying something else, in this case this "execute as {player} at @s run setblock ^ ^ ^ minecraft:chest\\{LootTable:"minecraft:chests/simple_dungeon"\\}" command, escaping the curly brackets, but that throws an error. Escaping the colon : and the double quotes inside the command also gives the same error.

• You only ever need to escape opening curly braces.
• Pay attention to how you are nesting quotes
• It’s the lack of a space after minecraft:chest intentional?
• What’s the error?

Even when just escaping the opening i get this error.

The lack of space is intentional (the original command is setblock ^ ^ ^ minecraft:chest\\{LootTable:"minecraft:chests/simple_dungeon"}"), which works without issue when used in the console.

Yeah, you need to pay attention to your quotes (You can’t use double-quotes inside of double quotes without escaping them).

I‘d suggest replacing your outer quotes with ’ and then replacing \\ with a single \

Thank you very much!
