I am trying to make the /blockdata command work on blocks within a radius of a mob. Basically, I am trying to make all signs around a zombie named "Empty_Child" change to say:

Mummy? Are you my mummy?

This is the command I am using so far, but it only works on the block the zombie is standing on: /execute @e[name=Empty_Child] ~ ~ ~ /blockdata ~ ~ ~ {Text1:"{\"text\":\"Mummy?\"}",Text2:"{\"text\":\"Are you my\"}",Text3:"{\"text\":\"mummy?\"}"}

  • NOOO! WHY WOULD YOU DO THAT?!? And it's even a great, spooky way to implement it in Minecraft, good job. But still: AAAAAHHH!!!

  • @Fabian Thanks! I gave the zombies gas masks (using custom heads) and they even infect villagers! I just need to find a way to get the sign editing working!

  • I just remembered that it's actually possible in 1.13, because you can specify a data tag for the block that you want to replace. Remember me again once 1.13 is (or at least somewhat usable snapshots are) out to write another answer.

  • Btw, SethBling once made a "weeping angels" concept in Minecraft, which you could now even improve with elytra.

  • I actually attempted at making Weeping Angels (with Elytra, too) some time ago using Sethbling's concept, but the commands became incompatible with the latest version of Minecraft. :/ All I have for Weeping Angels so far is a stray named "Weeping_Angel" wearing Elytra...

There's no way to use /blockdata in a radius.

I once made a command system to do something similar, but that's way too much effort and especially too much to process (I get about 5tps with it on a relatively good PC).

So I would recommend you to just execute the command multiple times, each with different relative coordinates, that should be the easiest solution for your case.

  • Thank you, but I don't know how to get those relative coordinates working. I tried adding a 1 after the ~ in a separate command block, but it failed to make a difference.

  • That's very weird, it should. Can you copy the exact commands from the command history (don't type here, copy to be extra sure) and link screenshots?

  • /blockdata ~1 ~1 ~1 {Text1:"{\"text\":\"Mummy?\"}",Text2:"{\"text\":\"Are you my\"}",Text3:"{\"text\":\"mummy?\"}"} minecraft minecraft-commands

  • No, I mean from in the game. You obviously copied the command from here, because you accidentally copied the tags.

  • I deleted the command block before you asked. Sorry :P
