DatapacksJava
RadioSign
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This is a very simple datapack that enables you to link signs together.
Linked signs share the same front text, back text, colors, glow, etc.
They can be waxed, but wax will not transmit to other signs. A waxed sign cannot be edited by hand, but it will continue to fetch messages from the network.
Radio signs support multiple channels, each sign can be linked to one channel at a time.
Note: hanging signs are supported alongside regular signs, however they are smaller than pre-1.20 signs, meaning that the text might get cropped. See the gallery for examples.
Steps to link a sign to the network:
- Stand inside the sign;
- Run
/trigger radio set <channel>command, where can be any integer above 0; - The sign is now linked!
If you want to unlink a sign from the network, simply break it.
