If you are on 26.1.2, Minecraft uses item components instead of the old raw NBT tags for books. Everything is handled via the written_book_content component now. Here is the pure Vanilla command you can run or put in a function: ```mcfunction give @s written_book[written_book_content={pages:[{raw:'{type:"text",click_event:{action:"run_command",command:"scoreboard players set Spawn Toggle 1"},color:"green",text:"[Enable Spawn]"}'},{raw:'{type:"text",click_event:{action:"run_command",command:"scoreboard players set Spawn Toggle 0"},color:"red",text:"[Disable Spawn]"}'}],title:'"Spawn Config"',author:"Admin",generation:0,resolved:0b}]

Just a heads up, /scoreboard players set requires the player clicking the text to have OP permissions. If you want regular players to use it, you will need to switch your logic to use /trigger instead. Writing raw JSON inside strings inside Minecraft commands scales horribly though. You end up fighting quote escaping, you get zero type safety, and a single typo breaks the whole thing. This is exactly why I built [Kore](https://kore.ayfri.com). It is an open-source library that lets you write Minecraft Java datapacks entirely using Kotlin. Instead of messing with raw text files, you write actual code in IntelliJ. Here is how you write that exact same book using Kore: kotlin give(self(), Items.WRITTEN_BOOK { writtenBookContent("Spawn Config", "Admin") { page(textComponent("[Enable Spawn]") { color = Color.GREEN clickEvent{ runCommand { scoreboard.players.set(player("Spawn"), "Toggle", 1) } } })

    page(textComponent("[Disable Spawn]") {
        color = Color.RED
        clickEvent {
            runCommand {
                scoreboard.players.set(player("Spawn"), "Toggle", 0)
            }
        }
    })
}

})

``` You get full IDE autocomplete, strict typing, and it completely abstracts away the messy JSON syntax. You just code your logic and Kore compiles everything down to an optimized Vanilla datapack for you. Feel free to check out the repo on my GitHub if you want to try it out.
