CampaignCore
by Cauli
CampaignCore lets players share and play music codes that point to MP3 files hosted on catbox.moe, in Minecraft 1.21.1 with Fabric.
What it does
Music codes are shared between players, and each one refers to an audio file uploaded to Catbox. The code's name is taken from the file's path on that site, so a code stands in for a track that the receiving player can hear in game. Audio files must be in MP3 format to work. CampaignCore can also play audio files that are present in the native Minecraft files.
The mod runs on the client alone, so only players need to install it, and servers do not. Files are published for Fabric only, for 1.21.1, with 1.0.0 as the latest build from 2026-02-23. The code is released under All rights reserved, so the mod is not open source. Playing music codes given by other players is left to each player's own discretion.
If Catbox is down, the files cannot be heard. Before reporting a problem with CampaignCore, check the status of catbox.moe, because the outage is on the hosting side and not in the mod itself. The mod has been tested on 1.21.1 with Fabric.
