Create Mechanical Spawner
by oierbravo
With Create Mechanical Spawner, a Create rotation-powered block generates mobs from a fluid, and the spawner can be set up in modpacks.
What it does
The mechanical spawner block is powered by rotation and produces mobs. The spawn source is a configurable fluid, and the spawned mob depends on the biome where the block stands, so the same block can yield different mobs in different places. A minimum rotation speed is required before spawning starts, and the fluid capacity is configurable as well.
The mod is intended for use in modpacks. Mechanicals Lib is required, and Just Enough Items and KubeJS are optional. Files are published for Forge and NeoForge across 1.19.2, 1.20.1 and 1.21.1. The mod is open source under the GNU Lesser General Public License v3.0 only, and it runs on client and server, so the server and every player need it.
Key features
Rotation-powered spawning
The block uses rotation power to generate mobs, with a minimum speed needed before it runs.
Fluid-based spawn source
A specific liquid supplies the mobs, and a configurable fluid capacity sets how much can be held.
Biome-dependent generation
The mobs produced depend on the biome the spawner is placed in, so placement changes the output.
Configurable behavior
Spawning speed, fluid capacity and related settings can be adjusted through the mod configuration.
