Project History

Originally born as a specialized system for House Protection and Safe Zones, this project quickly evolved as more complex RPG mechanics were integrated. To better reflect its comprehensive nature and its role as the backbone of a true RPG experience, the project was renamed from "Home Claim Property Protection" to AvalonEssentials. Today, it stands as a modular and powerful toolkit for server owners.

Design Philosophy: GUI-First Experience

AvalonEssentials is built with a single core principle: Immersion through Interaction. We believe that a true RPG experience should feel like a real game, not a text-based terminal. By replacing traditional, immersion-breaking slash commands with high-quality Graphical User Interfaces (GUIs) and physical world interactions, we ensure that players stay focused on the world of Avalon. Whether you are managing your guild, checking your bank balance at an ATM, or tracking quests in your journal, every action is designed to be tactile, visual, and intuitive.

Accessing the System

The gateway to all AvalonEssentials features is the Avalon Book (avalontm:book) item.

  • Automatic Delivery: New players receive the Avalon Book in their hotbar upon joining the server.
  • Visual Interface: Holding this item and interacting provides instant access to all RPG hubs: Character RPG Management, Profiles, Property Management, Banking, Guilds, and the Quest Journal.
  • Unified Navigation: There are no slash commands required for gameplay; the Avalon Book serves as the central launcher for every plugin system.
  • Admin Tools: Administrative features and advanced zone management are integrated directly into the Avalon Book interface for authorized staff members.
  • HUD Integration: While holding the book, players receive on-screen hints and status updates regarding nearby zones and active selections.

RPG System: Core Progression

A complete character progression system with classes, attributes, profiles, and active skills.

Profile Management

Players can maintain multiple RPG Profiles through the Avalon Book, allowing them to switch between different character setups:

  • Separate Progression: Each profile has its own Level, XP, Attributes, and Class.
  • Inventory Sync: Player inventories and equipped gear are tied to their active profile.

Attribute System

Six core statistics that define character growth and mechanical bonuses:

Attribute Effect Calculation / Bonus
VIT Vitality +10 Max HP per point
INT Intelligence +2 Max Mana and +0.1 Mana Regen/sec per point
STR Strength Increases Physical Damage and carry capacity
AGI Agility Increases Attack Speed and Movement Speed
DEX Dexterity Increases Critical Hit Chance (1% per point)
STAM Stamina Increases Max Stamina and +0.5 Stamina Regen/sec per point

Target Filters

Filter Behavior
SELF_ONLY Only affects the caster
ENEMIES Only affects hostile entities with EntityStatMap
ALLIES Only affects: caster, party members, guild members
ALL Affects any entity with EntityStatMap (except caster)

Ally Detection

The system automatically identifies allies to prevent accidental friendly fire and to target beneficial skills:

  • Players: Caster is always an ally. Party members and Guild members are automatically identified as allies.
  • NPCs/Mobs: Currently, NPCs and monsters are not treated as valid allies for skill targeting.

Skill Configuration (JSON)

Skills are configured via JSON files in mods/AvalonEssentials/RPG/Skills/:

{
  "id": "fireball",
  "name": "Fireball",
  "description": "Launches a fireball at enemies dealing 50 damage",
  "manaCost": 25,

  "radius": 3.0,
  "category": "DAMAGE",
  "power": 50.0,
  "requiredClassId": "mage"
}

Class Configuration (JSON)

}

How Skills Work

Activating a skill is a seamless process managed by the RPG engine:

  1. Activation: Players use the /cast command or interact with the RPG Hub to trigger a skill.
  2. Requirements Check: The system automatically verifies if the player has the required Level, Class, and sufficient Mana. It also checks if the skill is currently on cooldown.
  3. Execution: Once validated, the skill effect is applied based on its type:
    • Targeted Skills: Automatically find the nearest valid target (Enemy or Ally) in front of the caster.
    • Area Skills: Apply effects to all valid entities within a specified radius.
    • Self Skills: Apply buffs or heals directly to the caster.
    • Movement Skills: Instantly move the player via dashing or teleportation.

Commands

Command Description
/cast <skillId> Activate a skill

Economic Features

AvalonEssentials features a physical-first economy driven by world interactions.

Physical Currency (Coins)

Wealth is represented by physical Coin items dropped by mobs or found in loot. Players must collect and carry these assets.

ATM Banking System

Banking is handled exclusively via interactive ATM blocks:

  • Digital Storage: Deposit physical coins into your account via an ATM to protect them from loss upon death.
  • Interaction Hub: Manage your balance and view transaction history at any physical ATM.

Player Markets

  • Market Items: Establish personal shops using specialized Player Market items.
  • Interactive Browsing: Players interact directly with Market items in the world to buy goods.

Social and Community Features

Both Guild and Party systems are accessed directly through the Avalon Book interface.

Guilds

  • Hierarchy & Permissions: Manage ranks (Owner, Officer, Member) and permissions via the Guild Menu.

Minigame Engine

AvalonEssentials features a robust, action-based Minigame Engine designed for high-performance session management and immersion.

Inventory Management System

The plugin includes a robust inventory management system that automatically saves and restores player inventories when entering and exiting minigames and edit mode.

How It Works

  • Entry: When a player joins a minigame or edit mode, their current inventory is automatically saved to a backup file.
  • Exit: When leaving, the inventory is restored from the backup, returning all original items to the player.

Snapshot Types

The system uses separate backup files for different modes to prevent conflicts:

Type Filename Format Description
MINIGAME {playerId}_minigame.json Saved when entering a minigame
EDIT {playerId}_edit.json Saved when entering edit mode

Files Location

Inventory backups are stored in:

mods/AvalonEssentials/Backups/Inventories/

Key Features

  • Automatic Save: Inventories are saved automatically when entering minigames or edit mode
  • Automatic Restore: Original items are restored when leaving
  • Multiple Modes: Separate backups for minigames and edit mode prevent item conflicts
  • Safe Deletion: Backup files are deleted after successful restoration to prevent duplicates

Technical Details

The system is implemented in:

  • InventorySnapshotManager.java - Core inventory save/restore logic
  • MinigameService.java - Handles minigame inventory management
  • EditModeService.java - Handles edit mode inventory management
  • MinigameListener.java - Event listener for player state restoration

Configuration (minigame_config.json)

The engine uses a unified, JSON configuration. Settings are divided into gameSettings, scoreSettings, and the powerful Event System.
