About this Mod

Coupled usage of doors, fence gates, and trapdoors

Double doors (with opposing hinges) will open together when used
Vertically stacked fence gates will open together when used
All trapdoors (and opposing counterparts) along their side axes will open together when used
Any redstone signal above 7 (50%) will power all coupled blocks, whereas anything less will only power the immediate block
Each coupled block can be individually toggled in the configuration file (./config/couplings.toml)

This mod is recommended on both the client and server for more responsive block updates

Frequently Asked Questions

Couplings server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Couplings officially supports fabric for Minecraft 1.20.1, 1.20, 1.19.4. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Couplings – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Couplings consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
