Custom Weapons: Create your own YAML files in guns/ or melees/ folders and run /gun reload.

⚒️ Crafting Mechanics

1. Components (The Basics)

Craft raw materials like Steel Ingots, Gun Barrels, and Springs at a standard Crafting Table. These recipes are automatically unlocked in your Vanilla Recipe Book.

2. Assembly (The Advanced)

Place your components into the Mechanical Crafting Table.

• Non-grid-based: Just throw the ingredients into the 21-slot input area.
• Visual Preview: The output slot shows your gun stats before you build it.
• Recipe Guide: Click the Glowing Book icon in the station to browse all weapon requirements.

📊 Action Bar HUD

While holding any ranged weapon, CombatGunSSS displays a persistent HUD on your action bar:

🔫 AK47  ▐████████████░░░░▌  22 / 30  •  90

• Gun name is colored by rarity: white (common) → aqua (rare) → light purple (epic) → gold (legendary).
• Visual bar transitions green → gold (≤25%) → red (≤10%) as ammo depletes.
• Reserve count turns red when you have no backup ammo left.
• The HUD automatically yields to the reload progress bar during active reloads.

combatgun:
  hud:
    enabled: true
    update_interval_ticks: 5

🎯 ADS — Aim Down Sights

Enable ADS per gun in its YAML config:

ads:
  enabled: true
  spread_multiplier: 0.35   # 65% tighter accuracy while ADS
  movement_penalty: 0.6     # movement speed while ADS active

Control: Shift+Right-click to toggle ADS on/off. Action bar shows 🎯 ADS [spread ×0.35].

ADS exits automatically when you switch items, teleport, or die. Scopeable sniper rifles use the traditional sneak-to-scope mechanic instead of ADS.

🩸 Bleeding

An optional damage-over-time system. When enabled, bullets hitting players have a configurable chance to cause bleeding.

combatgun:
  bleeding:
    enabled: true
    chance: 0.15
    damage_per_second: 1.0
    duration_seconds: 10
    cure_item: bandage

Hold a bandage (crafting component) and press [F] to cure. Bleeding stops automatically on death.

🎒 Ammo Pouch

A compressed ammo container that stores hundreds of rounds in a single slot.

/gun givepouch ar_ammo 300 PlayerName

Shift+Right-click to unpack all rounds into your inventory. Surplus rounds are left if the inventory is full.

🌐 Multi-Language

Set the active language in config.yml:

combatgun:
  language: vi   # en | vi | (any lang/xx.yml)

Bundled: English (en) and Tiếng Việt (vi). Add a custom translation by placing lang/xx.yml in the plugin data folder and running /gun reload.

🔌 Plugin Integrations

PlaceholderAPI

8 real-time placeholders for use in scoreboards, TAB, AdvancedHud, and similar plugins:

Vault Shop

Enable the shop in config.yml, set prices per gun, then players can buy weapons in-game:

combatgun:
  shop:
    enabled: true
    currency_symbol: "$"
    guns:
      ak47:  700.0
      awm:  2500.0
      knife: 100.0

/gun buy ak47          # purchase for configured price
/gun buy ak47 free     # admin free-give (requires combatgun.admin)

WorldGuard

The custom flag gun-shooting is automatically registered when WorldGuard is present:

/rg flag <region> gun-shooting deny    # block all guns in region
/rg flag <region> gun-shooting allow   # explicitly allow
/rg flag <region> gun-shooting -g      # remove flag (inherit parent)

Falls back to WorldGuard's built-in PVP flag if gun-shooting is not set on a region.

Anti-Cheat (Vulcan / Matrix)

Auto-detected. When present, players are exempted from motion checks for anticheat.exempt_ticks ticks after each shot to prevent recoil from triggering false positives.

combatgun:
  anticheat:
    exempt_ticks: 3

📜 Commands & Permissions

Player Permissions

• combatgun.use — Allows shooting and using guns (default: true)
• combatgun.use.<gun_id> — Per-gun permission node (e.g. combatgun.use.awm)

📋 Changelog

See CHANGELOG.md for the full version history.

2.3.0 — Critical exploit + melee combat fix

• Fixed ammo/component items (built on vanilla materials like gold/iron nuggets) being craftable or smeltable into real vanilla resources without a resource pack — closed both the crafting-grid and furnace-smelting paths
• Fixed melee weapons (katana, knife, pan, etc.) dealing no damage and not affecting the target at all — hit sound played but the attack silently did nothing due to an event-recursion bug

2.2.0 — Permission-gate fix release + Recipe Browser categories

• Fixed /gun command tree blocking every player-facing subcommand (buy, attach, detach, attachments, stats, leaderboard, recipe) for non-admins — both onCommand() and onTabComplete() were hard-gated behind combatgun.admin
• Fixed VaultHook.buyGun() silently discarding a purchased weapon when the buyer's inventory was full
• Added Gun / Melee / Ammo category tabs to the Recipe Browser so players can find craftable items faster

2.1.0 — Bug-fix release: 8 bugs fixed

• Fixed StatsManager.flushBuffer() race condition — kill data silently lost under concurrent load
• Fixed ThrowableManager tasks not cancelled on plugin disable — IllegalPluginAccessException on every disable
• Fixed clearAds() removing scope slowness incorrectly
• Fixed all ReloadManager messages bypassing i18n (hardcoded English shown to vi servers)
• Fixed BleedingManager and ThrowableManager using Math.random() instead of ThreadLocalRandom
• Fixed AttachmentManager and GunListener duplicate import statements
• Fixed getRecentDamage() exposing mutable map reference; added safe getDamageRecord() lookup

2.0.6 — Bug-fix release: 4 bugs fixed

• Fixed friendly-fire scoreboard team detection using player scoreboard instead of main scoreboard — could allow friendly-fire bypass
• Fixed recentDamage memory leak: entries now removed on player quit and death events
• Fixed shared static Random contention: replaced with ThreadLocalRandom.current() (per-thread, no lock, better entropy)
• Fixed async SQLite connection safety: incrementGunKill() and getGunKills() now synchronized alongside flushBuffer()

2.0.5 — Developer API & architecture release: 4 new additions, 1 improvement

• New AttachmentApplyEvent and AttachmentRemoveEvent (cancellable) — fired on /gun attach and /gun detach
• New DamageCalculator utility class — centralises all damage math extracted from GunListener (headshots, falloff, spread, pellets)
• New kills_by_gun_detail SQLite table (schema v3) — per-kill log with timestamp, weapon, headshot flag
• New commands: /gun statsreset <player> and /gun seasonreset confirm
• GunListener God Class partially refactored — 4 methods delegate to DamageCalculator

2.0.4 — Stability & performance release: 2 bug-fixes, 3 improvements

• Fixed thread-safety data race in StatsManager stat buffer (ConcurrentHashMap)
• Fixed silent loading of invalid gun configs (YAML validation with clear per-field errors)
• StatsManager leaderboard query optimized with a kills DESC index (schema migration v2)
• Shop price reads now cached in memory; invalidated on /gun reload
• Config version detection warns admins when config.yml is outdated after an update

2.0.3 — Bug-fix release: 7 bugs fixed

• Ammo Pouch no longer loses items when the inventory is full
• Reload task CPU usage reduced by 50% (changed from 1 tick to 2 tick interval)
• isHeadshot() now works accurately when the player is crouching
• craftFromStation() properly rolls back ingredients if crafting fails
• BleedingManager now uses wall-clock time for accurate damage even during server lag
• applyRecoil() is now fully null-safe
• Fixed race condition in onItemHeldChange

🔍 Troubleshooting

❓ FAQ

Does this work on Spigot?

No — CombatGunSSS requires Paper 1.21+. Spigot lacks several API features used internally.

Can I add my own guns?

Yes. Create a new .yml file in plugins/CombatGunSSS/guns/ following the same format as the built-in weapon files, then run /gun reload.

Can I disable specific guns?

Simply delete or remove the gun's YAML file from the guns/ folder and run /gun reload. Players holding that gun will keep the item but it won't function.

Does it support multiple worlds?

Yes. Configure a world whitelist or blacklist under combatgun.worlds in config.yml.

Is it laggy on large servers?

CombatGunSSS uses hitscan (ray-trace, not projectile entities), so it is significantly lighter than projectile-based gun plugins. Heavy effects like bullet trails can be toggled off in config.yml under combatgun.effects.

Can I disable the crafting system?

Yes — simply don't give players the Mechanical Crafting Table or Recipe Book. Use /gun give for admin distribution. Vanilla workbench recipes can also be disabled per-item.

Do I need a Resource Pack?

No. The plugin works without a resource pack. However, each gun has a custom_model_data value pre-configured for you to link 3D models if you have a pack.

Can I disable bleeding or the Ammo Pouch?

Yes. Set combatgun.bleeding.enabled: false or combatgun.ammo_pouch.enabled: false in config.yml.

Does it support ZombieApocalypseSSS?

Yes — CombatGunSSS is the recommended gun companion for ZombieApocalypseSSS. Guns deal full damage to all zombie types and trigger the noise / aggro system automatically.

Can other plugins listen to gun events?

Yes. Four custom events are exposed via the API: GunShootEvent (cancellable), GunReloadEvent (cancellable), GunHitEvent, and GunHeadshotEvent. See the Developer API section.

How do I give guns without the shop?

Use /gun give <id> [player] (requires combatgun.admin). Example: /gun give awm Steve.
