I wanted to compose a bunch of commands in an external editor and then paste them all to execute in the Minecraft console (chat window).

But if you paste multiple lines, it seems to just ignore the line breaks. My next thought was to use a separator between commands, such as a semicolon, but after a bit of DuckDuckGoing I couldn't find any such separator.

This is for a realm, and I'm running the Java version.


For example, I'd like to be able to do things like compose a little script like this in an external editor:

/setblock 0 0 0 air
/playsound block.bell.use master @p

Then copy it to clipboard, open Minecraft and press "t" to open the command line / chat. Then if I paste, unfortunately what I get is

/setblock 0 0 0 air/playsound block.bell.use master @p

What I'd like to happen is for it to run several commands.

Update I don't mean functions, as I want anyone to be able to paste in commands, not only realm admins but anyone with cheats on.

  • Why do you want to do this? You can just execute the commands one after the other. – Fabian Röling Feb 16 at 12:12
  • @FabianRöling For example if I created a tool that turns a 16x16 pixelart into setblock commands, that might be 256 commands, which would be too many to paste in separately. If I require downloading and reuploading the realm, then non-admins would not be able to use it. – Bemmu Feb 16 at 12:30

Before functions and structure blocks existed, the best way to send someone a command block contraption was a "one-command-creation", which summoned a falling command block riding a falling command block riding a falling command block …

Currently there is a bug that breaks these: https://bugs.mojang.com/browse/MC-145113
But you can work around it by using other entities in between that instantly die. So you can for example do it like this:

summon falling_block ~ ~2 ~ {Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 1"},Passengers:[{id:"armor_stand",Health:0,Passengers:[{id:"falling_block",Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 2"},Passengers:[{id:"armor_stand",Health:0,Passengers:[{id:"falling_block",Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 3"}}]}]}]}]}

This executes all three commands, say 1, say 2 and say 3, in that order. If you also want to clean up afterwards, you can simply add another command block that removes the tower:

summon falling_block ~ ~2 ~ {Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 1"},Passengers:[{id:"armor_stand",Health:0,Passengers:[{id:"falling_block",Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 2"},Passengers:[{id:"armor_stand",Health:0,Passengers:[{id:"falling_block",Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"say 3"},Passengers:[{id:"armor_stand",Health:0,Passengers:[{id:"falling_block",Time:1,BlockState:{Name:"command_block"},TileEntityData:{auto:1,Command:"fill ~ ~-3 ~ ~ ~ ~ air"}}]}]}]}]}]}]}

Michael Dibbets/Tschallacka has created a generator in 2020 for these combined commands: https://jsfiddle.net/Tschallacka/evwb39dr/embedded/result (archive)

Enter your commands in the text field above the red button, one per line, without slashes in front (so like a function) and press the button. The bottom text field will then contain the combined command.
The generator does not validate if the commands are valid and it does not ignore empty lines or lines starting with #, so you cannot simply copy-paste function files into it.

  • I suspected some hack like this must be possible. Thank you! – Bemmu Feb 17 at 11:47

    felt inspired by your answer, don't know if there is already one out there jsfiddle.net/Tschallacka/evwb39dr/embedded/result – Tschallacka Feb 17 at 16:18
  • @Tschallacka Awesome! But I already found a bug: The /fill command always goes three blocks down, no matter how many commands I enter. It should be as many blocks down as I entered commands. – Fabian Röling Feb 17 at 16:46
  • But that could potentially go through bedrock then? How about replacing with lava to eat the tower when the entities drop in? – Tschallacka Feb 17 at 23:42

    @FabianRöling updated it, better like this? And I cared because I was thinking of adventure maps etc... where players might slip somehow down. but the command blocks would be sealed off then anyways – Tschallacka Feb 18 at 9:36

You could do this by writing a function (.mcfunction file) and placing it in a datapack in the map folder. To create a function, follow these steps:

  1. Open notepad (or your text editor of choice), and enter the commands you wish to run, each on their own line.
  2. Save the file, name it whatever you want, (replace .txt with .mcfunction) on your desktop.
  3. Create folders in this order:

    datapacks / [name of datapack] / data / [namespace] / functions

  4. Move the .mcfunction file you created into the functions folder, and move the datapacks folder into your world folder. (for a Realm, you will first need to download the map - go to World backups and Download latest)

  5. (for a Realm) Upload the modified map to the Realm.

  6. Run the function with /function [namespace] : [function name]. This can be done by a player or from a command block.

Note: @p selector will be relative to the command block or player that ran the function, in this usecase I'm assuming @a would fit better.

  • Thanks, so sounds like pasting multiple isn't possible. I wanted anyone on a realm to be able to paste the commands, not just admins, and would have been more user-friendly to not require downloading and uploading. – Bemmu Feb 16 at 11:35
  • As an admin/just a guy who runs his own server, this is perfect! Now I can script up all my command files and just run them from my world – tmck-code May 3 at 23:09

You could have the pixel art already created then clone it to the position then play the bell sound to the player, this is best done with tags so everything goes to the right player .

One thing you could also do is to have a structure block with the commands already inside, then have setblock command that places preset structureblock
