Carpet RMS Addition
Carpet RMS Addition, a Fabric add-on for the Carpet mod, ports several vanilla behaviors from newer and older Minecraft versions and adds controls for entity packets and spawning.
What it does
Carpet RMS Addition extends Carpet with settings that change how certain game behaviors work. Some settings restore behavior from earlier releases, such as end portal platform item drops, fireball explosion credit, and falling block logic from 1.18.2 onward. Other settings control server load: packets for chosen entities and particles can be intercepted to save network throughput, and entities on a blacklist can be stopped from spawning naturally or from using portals.
Spawning and redstone are also covered. Block and sky light levels can be overridden for natural monster generation, which is useful when designing end-of-light farms. Dispensers, droppers and note blocks can be made to check the state of blocks placed by a player and to trigger silently, and note blocks can be set to one of two modes that differ in whether they play sound. Fake players use offline UUIDs rather than querying the Mojang API, which prevents server freezes when that API is slow or unreachable.
Carpet RMS Addition is a Fabric mod and requires Carpet. It is published for 1.17.1, 1.20.1, 1.20.4, 1.21.1, 1.21.4 and 1.21.6 under the GNU Lesser General Public License v3.0 or later, and is open source.
