NuLLStar

Effects

• Effect engine with 6 types: PARTICLE, FIREWORK, LIGHTNING, FALLING_BLOCK (falling meteors), TNT_SCATTER (harmless primed TNT) and COMBO (layered effects).
• 16 animated particle shapes: HELIX, DOUBLE_HELIX, CIRCLE, EXPANDING_RING, FOUNTAIN, VORTEX, PILLAR, AURA, GALAXY, TORNADO, SPHERE, HEART_SHAPE, CROWN, BEAM, METEOR, WINGS.
• 30 ready-to-use effects split into 3 categories (10 each):
  • Basic: Flame Helix, Heart Fountain, Arcane Halo, Aqua Splash, Emerald Glimmer, Note Twirl, Smoke Pillar, ✨ Firework, Star Burst, Creeper Boom.
  • Special: RGB Vortex, Double Helix, Soul Ring, Snow Flurry, Galaxy Spiral, Angel Wings, Flame Spiral, Frost Nova, Ender Aura, Love Halo.
  • Administrative: Thunder Strike, Crown of Glory, Divine Beam, Dragon Aura, Inferno Spiral, Nebula, Meteor Shower, Sonic Boom, Totem Blessing, Big Bang.
• Per-effect customization: icon, display name, lore, particle, shape, colours (hex), size, radius, points, height, duration, rotation, count and speed.
• Optional custom sound per effect (key, volume, pitch).
• Optional per-effect join-message override.
• RGB / ✨ dust support and per-version particle name aliases (e.g. REDSTONE → DUST).
• Effects can be enabled/disabled individually via enabled: in effects.yml.
• Safe rendering: a failing effect logs once and stops instead of flooding the console.

GUI

• Two-level menu system: a main hub (player info head + 3 category heads) and a paginated category menu.
• Optional custom base64 skull textures for category heads (with a material fallback).
• Live preview head showing the player's currently active effect.
• Navigation: previous/next page, back, and a disable button.
• Fully configurable layout — titles, rows, slots, borders, content slots and all lore live in messages_<lang>.yml.
• Selected effect is highlighted (glow + status line).

Permissions

• Own permission per effect (nstar.effect.<id>).
• Tier wildcards: nstar.category.basic / special / administrative.
• nstar.use, nstar.admin, nstar.delaybypass.

Commands

• /nstar — open the menu (with menu / gui aliases).
• /nstar off — disable your effect.
• /nstar discord, /nstar version, /nstar help.
• /nstar reload — reload config, messages and effects.
• /nstar admin on <player> <effect> — force-grant an effect (plays on join even without permission).
• /nstar admin off <player> — clear a player's effect.
• Permission-gated tab completion for every subcommand.
• Extra command aliases configurable in config.yml.

Storage

• Selectable backend: SQLite (default, local data.db) or MySQL, both via HikariCP.
• Selections persist across relog and restart.
• Automatic table creation and migration of the forced column for older tables.
• Drivers downloaded by Paper at runtime via plugin.yml libraries — no shading required.

Modules & integrations

• Join-messages module — optional broadcast on join, can override the vanilla message.
• Anti-spam cooldown between effect changes, bypassable with nstar.delaybypass.
• PlaceholderAPI expansion: %nstar_effect%, %nstar_effect_name%, %nstar_effect_permission%, %nstar_has_effect%.
• Modrinth update checker — notifies admins on join when a newer version is available.

Localization & text

• Ships with English and Polish; language selectable via language: in config.yml.
• Zero hard-coded user-facing strings — everything lives in messages_en.yml / messages_pl.yml.
• Full colour support: MiniMessage tags, gradients, <#RRGGBB> and legacy & / &#RRGGBB codes, with a safe fallback parser.

Technical

• Targets Paper / Purpur 1.21.10, Java 21, built with Maven.
• Asynchronous database reads/writes with an in-memory cache.
• Dynamic command registration via CommandMap.
