Unlimited Spawners
Upgrade your monster spawners, allowing them to spawn mobs without a player in range.
About this Mod
Unlimited Spawners
Overview
Allows mob spawners to continue spawning mobs, even when a player is out of range, as long as they have a certain block above them. The block(s) that enable unlimited spawning are fully configurable. By default, a netherite block is required.
Usage
In order to enable unlimited spawning for a given spawner, simply place a configured block directly on top of the spawner.
Installation
Server: REQUIRED
Client: OPTIONAL
Installing the mod on the server alone provides all functionality. If clients do not install the mod, they will not be able to see that spawners are still active when outside of the vanilla activation radius, even though the spawners will still be functionally unlimited.
