Description

String Utilities Mod

A mod that provides more NBT string operations.

一个提供更多 NBT 字符串操作的模组。

Syntax 语法

/string <method> [target] [source...]

The target and source parts are similar to what follows the data modify command.\ target和source部分与data modify命令后面的部分类似。

Example 例子

/string isEmpty value "" returns 1

/string indexOf value "asdfghjkl" value "qwerty" returns -1

/string escape storage a:b c value '\'quote"slash\\' stores 'quote\"slash\\ into foo:bar/baz

/string strip storage foo:bar baz value " a 123 " stores a 123 into foo:bar/baz

/string concat2 storage a b from entity @s SelectedItem.id from entity @s Inventory[0].id

/string join storage test playerUUID from value "~" from @s UUID
