Redstone Essentials
by CybriSoft
Redstone Essentials is a Fabric utility that adds debugging features and quality-of-life tools for complex redstone builds, with full multiplayer support.
What it does
The mod aims to improve the redstone experience for builders working on complex computational circuits. Its tools focus on debugging redstone, and selections made with its sessions are shared with online players, so a group can work on the same build together.
Sessions hold multiplayer selections, so the session manager does not have to be asked for them one by one; players who join a session load into it accordingly. The mod is built around a worldediting workflow, and a separate line of work adds features for a second building tool. Redstone Essentials is open source under the GNU General Public License v3.0 only, and its source code, issue tracker and wiki are public. Files target game versions 1.21 – 1.21.7 and use MidnightLib as an optional dependency for configuration.
Key features
Redstone debugging tools
A set of debugging features helps find faults in complex redstone circuits while they are built and tested.
Multiplayer sessions
Sessions carry multiplayer selections, and online players can join a session and load into it together.
Configuration with MidnightLib
Settings are cleaner to edit through MidnightLib, and the config can also be changed in-game from the mod list.
Session information
A wiki page describes how sessions are found and how they relate to the selections of each player.
