FFAUtils

A free-for-all utilities plugin for Paper 1.21.4: kits, multiple spawns, combat logging, stats, and spawn access gated by a player's PvP tier from MCTiers, PvPTiers or EliteStorm.

---

Features

• Kits — create, edit and delete kits from an in-game inventory editor. Kits are stored one JSON file each.
• Multiple spawns — name any location as a spawn, and optionally restrict which kits may be used there.
• Tier-gated spawns — require a minimum PvP tier (for example HT3 or better) to enter a spawn, resolved from MCTiers, PvPTiers or EliteStorm. See Tier-gated spawns.
• Combat log — players tagged in combat are killed on quit and cannot run configured commands while tagged.
• Lobby items — a configurable hotbar for players in the lobby, plus a respawn item for players who died with a kit loaded.
• Stats — kills, deaths and K/D stored in SQLite, exposed through PlaceholderAPI.
• Death messages — a configurable pool of broadcast messages, with killstreak announcements.

Requirements

Server	Paper 1.21.4 (uses the Paper plugin descriptor and Brigadier command API)
Java	21
Optional	PlaceholderAPI, packetevents

Both optional dependencies are soft — the plugin loads fine without them, and simply skips registering placeholders when PlaceholderAPI is absent.

Installation

1. Download FFAUtils-<version>.jar from the releases, or build it yourself (see Building).
2. Drop it into plugins/.
3. Start the server once to generate the config files, then edit them and run /ffautils reload.

Commands

Every permission defaults to operators.

Players

Command	Permission	Description
/loadme <kit> <spawn>	none	Load a kit and enter a spawn. This is where kit restrictions and the tier gate apply.
/spawn	ffautils.commands.spawn	Teleport back to the lobby, healed and with lobby items restored.
/dead	none	Kill yourself.
/kit <name>	ffautils.commands.kit	Apply a kit.
/kit list	ffautils.commands.kit	List available kits.

Administration

Command	Permission	Description
/kit create|edit|delete <name>	ffautils.commands.kit	Manage kits. create and edit open the inventory editor.
/ffakiteditor	ffautils.commands.ffakiteditor	Open the kit editor menu. Player only.
/setspawn create <name>	ffautils.commands.setspawn	Save your current location as a spawn.
/setspawn delete <spawn>	ffautils.commands.setspawn	Delete a spawn.
/setspawn allowkit <spawn> <kit>	ffautils.commands.setspawn	Restrict a spawn to a kit. A spawn with no allowed kits permits all of them.
/setspawn removekit <spawn> <kit>	ffautils.commands.setspawn	Remove a kit from a spawn's allowed list.
/ffautils reload	ffautils.commands.ffautils	Reload messages, kits, spawns and death messages. Player only.
/tiers …	ffautils.commands.tiers	Manage the tier gate — see below.

Other permissions

Permission	Effect
ffautils.bypass-combat-block	Run blocked commands while tagged in combat.
ffautils.tiers.bypass	Enter tier-restricted spawns regardless of rank.

The spawn named lobby is special: it is where players are sent on join and by /spawn. If it does not exist, the first world's spawn point is used.

Configuration

File	Purpose
config.yml	Main settings, including the whole tier gate.
messages.yml	All player-facing strings, in MiniMessage format.
death-messages.yml	Pool of death broadcast messages.
blocked-commands.yml	Command labels players cannot run while in combat.
spawn-lobby-items.yml	Lobby hotbar items and the respawn item.
spawns/<name>.json	One file per spawn (location plus allowed kits).
kits/<name>.json	One file per kit.
stats.db	SQLite database of kills and deaths.

messages.yml is never overwritten on update. Strings added by a newer version are seeded automatically, so the file stays valid across upgrades.

Main config.yml keys

disable-lobby-items: false      # skip giving lobby items entirely
stats-database-name: stats.db   # SQLite file inside the plugin folder
combatlog.timeout-ticks: 300    # how long a combat tag lasts, in ticks

Combat log duration may also be given in seconds as duration-combat-log, which is multiplied by 20. If neither key is present the default is 15 seconds.

Tier-gated spawns

Requires a minimum PvP tier to enter a spawn. Ranks follow the convention all three sites share: tier 1–5 where lower is better, plus a position — 0 for high, 1 for low. So tier: 3, pos: 0 means HT3 or better, which lets HT3 in and turns LT3 away.

The gate is off until you turn it on:

/tiers                        # state, providers and restricted spawns
/tiers on | off | toggle      # enable or disable, persisted to config.yml
/tiers reload                 # re-read the tiers config section
/tiers cache clear            # drop every cached tier
/tiers check <player> [provider]

Configuration

tiers:
  enabled: false
  provider: "mctiers"     # mctiers | pvptiers | elitestorm | any
  gamemode: "vanilla"     # or "best" to use the player's strongest gamemode
  tier: 3                 # 1-5, lower is stricter
  pos: 0                  # 0 = high, 1 = low

  restricted-spawns:
    tryhard:              # each spawn may override tier, pos, gamemode, provider
      tier: 3
      pos: 0
      provider: "mctiers"

  use-peak-when-retired: true   # judge retired players on their peak tier
  allow-on-error: true          # unreachable API: true lets players in, false blocks
  cache-minutes: 30             # tiers are cached per UUID, per provider
  prefetch-on-join: true        # so the check at /loadme costs no request
  bypass-permission: "ffautils.tiers.bypass"

Spawns not listed under restricted-spawns are never gated.

Providers

Every lookup is cached per UUID per provider, prefetched when the player joins, and kept across reconnects, so the gate normally resolves without any request at all.

	MCTiers	PvPTiers	EliteStorm
Endpoint	mctiers.com/api/v2	pvptiers.com/api	api.elitestorm.es/v2
Looked up by	UUID with dashes	UUID without dashes	nickname (or UUID without dashes)
Gamemodes	vanilla sword axe pot nethop uhc smp mace	sword axe pot neth_pot uhc smp mace crystal	vanilla sword axe pot nethop uhc smp mace

Equivalent gamemode slugs are translated automatically between sites, so nethop matches PvPTiers' neth_pot. A gamemode that only exists on one site (vanilla on MCTiers and EliteStorm, crystal on PvPTiers) simply yields no ranking elsewhere, and the player is turned away by that provider.

provider: any checks every site and lets the player in if any of them allows it — useful because the sites genuinely disagree about the same player. A site that actually answered always outranks one that could not be reached, so allow-on-error only applies when no provider answered at all.

EliteStorm and offline-mode servers. EliteStorm is looked up by nickname by default, which is what makes the gate work on offline-mode servers: there the UUID Bukkit hands out is generated locally and never matches the Mojang UUID the other sites are keyed by. Set providers.elitestorm.lookup-by: uuid to use the UUID instead. Its gamemode ids are scoped to a Discord guild, so set providers.elitestorm.guild-id if you use a different one — the plugin reads the vocabulary from the API at startup.

Threading

Every lookup runs on a dedicated thread pool; nothing HTTP-related touches the main thread, including startup and reload. If a site is slow or down, the server keeps ticking.

PlaceholderAPI

Placeholder	Value
%ffa_kills%	Player's kills
%ffa_deaths%	Player's deaths
%ffa_kdr%	Kill/death ratio
%ffa_kit_<name>_players%	Players currently in FFA using that kit

Building

./gradlew shadowJar   # fat JAR into build/libs/
./gradlew test        # run the test suite
./gradlew runServer   # Paper 1.21.4 test server with the plugin deployed

Gradle's configuration cache is enabled. If you change build.gradle.kts, run with --no-configuration-cache or clear .gradle/configuration-cache/.

See AGENTS.md for the project layout, architecture notes and the details each tier provider depends on.

Known issues

• time-combat-log in the default config.yml is not read by anything. Combat log duration comes from combatlog.timeout-ticks or duration-combat-log — see Main config.yml keys.
