Elements: Utilities

A server-side mod for NeoForge 1.21.1 that covers the things server management mods usually leave out: spawner and mob stacking, item cleanup, mob caps, a lag report and a set of small tweaks. Every feature has its own on/off switch. It runs on its own; no other mod is needed.

Spawners

• Silk Touch keeps the mob. Spawner items only carry their mob, so spawners of the same mob stack in your inventory.
• Stacking: right-click a placed spawner with a spawner item of the same mob to add it to the stack (up to 12). Sneak + right-click places it as a new block. Claim mods can stop this like any other block click.
• Settings don't merge. The placed spawner keeps its own settings, including other spawner mods' upgrades. The stack only multiplies its output.
• Output: a stack of N spawners cycles N times as often, and each cycle releases 1 to N mobs. One stack never releases more than 6 mobs per 5 seconds.
• Stacked mobs: spawner mobs merge into stacks of up to 100. A spawner keeps at most 6 stacked mobs alive. When all 6 are full the spawner stops, and it starts again once every one of them is dead.
• No AI: spawner mobs don't walk, attack or target anyone. Gravity, water, fans and knockback still move them, so they can be carried to a kill spot.
• No loot bags from spawner mobs.
• Breaking: with Silk Touch, a normal break drops the whole stack and sneak + break drops one. Without Silk Touch one spawner of the stack is destroyed and nothing drops.
• Explosions and Create drills and saws can't break a stack.

Create farming

Only active when Create is installed.

• Every Create machine that damages mobs (saws, drills, crushing wheels, fans, rollers, deployers) counts as a player kill, so mobs drop XP and player-only loot.
• Drops are normal items, so funnels and belts pick them up.
• XP drops as Experience Nuggets (3 XP each).

Mob stacking

• Identical idle mobs standing together merge into one mob with the count in its name, up to 12.
• Only the front mob takes damage. Its death is a normal kill with drops and XP, and the next mob takes its place. Fall damage, lava and magma blocks work the same way, so a magma block floor makes a good kill spot.
• A lead or name tag pulls one mob out. With Carry On, sneak + right-click with an empty hand picks up one mob.
• Breeding food pulls two mobs out to breed. Shearing a stack shears every sheep in it. Milking gives one bucket, and a chicken stack lays one egg at a time.
• Bred, tamed, named and leashed mobs never stack. A stack counts as 1 entity for chunk entity limits.
• A hostile stack despawns as a whole. Passive stacks don't despawn.
• /kill removes a whole stack at once.

Items

• XP orbs merge into one orb when they land near each other.
• Dropped items of the same kind merge into one stack.
• Cleanup: staff clear dropped items with /utilities cleanup, after a chat countdown. Set mode = "timer" in settings.toml to clear them on a timer instead (every 10 minutes by default). Items on claimed land, named items, loot bags and items a player just dropped are left alone.
• Chunk cap (off by default): sets the most dropped items allowed per chunk. Items are merged first, then the oldest are cleared.
• Valuable items (off by default) stay on the ground longer.

Loot bags

Utilities doesn't add loot bags; it hooks into loot bag mods. These are detected at start, and their items are treated as loot bags:

• LootBoxesPlus (Loot+)
• Mob Loot Bags
• Dungeon Loot Bags
• Treasure Bags
• Loot Bags Renewal
• LootBags+
• Mark's LootBags

Other loot bag items or mods go in [loot_bags] in settings.toml.

Performance

• Hostile mob cap: limits natural hostile spawns per loaded chunk, counted the vanilla way (vanilla 70, default 40). Spawner mobs and passive mobs aren't affected.
• Smart hoppers: idle hoppers stop checking every tick. They wake up when a block next to them changes or an item lands in them.
• Villager slowdown: villagers boxed into small spaces, such as trading halls, update every 4 ticks. Trading, restocking and breeding work the same.
• Redstone clock limiter (off by default): very fast redstone clocks are slowed or broken.

Small tweaks

• Faster leaf decay after a tree is cut, however it's cut.
• Sapling self-planting (off by default) on grass or dirt.
• More bone meal targets: sugar cane, cactus, nether wart and vines.
• Double doors open together (vanilla and modded doors).
• Keep XP on death: players keep a percentage of their XP (50% by default).
• Right-click harvest: right-click a fully grown crop to harvest and replant it. Claim mods can stop it.
• Mob griefing per mob: pick which mobs can't change blocks, instead of the all-or-nothing game rule.

Commands

An optional lag alert (off by default) tells online staff when a chunk passes a threshold, with a long cooldown per chunk.

Permissions

Nodes are utilities.<name> and work with any permission mod or with OP levels.

Config

config/elements_utilities/

• features.toml: an on/off switch for every feature, plus the overlap guard
• settings.toml: numbers and lists for each feature, such as stack sizes, timers, item lists and mob lists
• messages.toml: every message, with & color codes

Item and mob lists take full ids (minecraft:diamond) or a whole mod (lootboxesplus:*).

Overlap guard

When another installed mod already does the same job, that feature turns itself off. Installed mods are checked at server start and on /utilities reload.

The list is overlap_guard.mods in features.toml, written as "feature=modid", so you can add mods without a rebuild. Add a feature to overlap_guard.force_on to keep it on anyway.
