YepBlocked
by BEQUIETBRO
YepBlocked lets server owners control which mobs and animals spawn, through config files and in-game commands that take effect after a reload.
What it does
Spawn rules are set per mob or animal and cover the natural world, including day and night cycles and biomes. The same rules can cover monster spawners and trial spawners, and a global toggle can block spawn eggs or the phantom spawns that appear over time.
Entries use a flag syntax, so a single line such as a zombie entry can set whether it spawns naturally, whether its spawn egg is allowed, and how it is handled. Glob patterns with regular expressions match whole groups of entities at once, and per-entity overrides fine-tune one mob without changing the rest. Changes applied with the reload command take effect at once, and a restart is needed only in some cases.
YepBlocked runs on the server, so players join without installing it. It requires Kotlin for Forge on the Forge build. The mod is published for Fabric, Forge and NeoForge across 15 release versions, 1.21.1 – 26.2, and is open source under the GNU Affero General Public License v3.0 only.
Key features
Per-mob spawn rules
Each mob or animal can be allowed, blocked or adjusted separately, with natural spawns handled apart from spawners.
Global toggles
Single switches block spawn eggs, phantom spawns and natural spawner or trial spawner spawns across the whole world.
Glob and regex matching
Patterns select entire groups of entities at once, such as every golem, instead of listing each one.
In-game commands
Commands with tab completion add or change rules without editing files, while manual config editing stays available.
