Disable Trial Spawners
by WozuXbox
Disable Trial Spawners lets server owners switch off trial spawners, and players can turn them off for a time with a key item.
What it does
The mod is a datapack that lets players temporarily disable trial spawners. Once a spawner is disabled, it stops generating mobs until the cooldown runs out. When the cooldown runs out, custom trial spawners from other mods keep their stored state, because the datapack leaves their data alone.
Access is handled through keys of three tiers. A copper key lasts 1 use, a diamond key 10 uses and a netherite key 40 uses. An admin book gives clickable commands that hand out keys and show the keys found so far. Several config options restrict when the functionality can be used, so a server can limit it to certain conditions.
The server must run it, while players may leave it out. Servers need the mod for it to work, while players may add it to their clients without changing play. Builds exist for Fabric and NeoForge, covering 1.21 – 1.21.3, and the code is licensed under the GNU Lesser General Public License v3.0 or later, so the mod is open source.
