NPCMark42

◆ WHAT IS NPCMark42?
NPCMark42 is a powerful and highly customizable NPC framework for modern Minecraft servers.
Unlike a basic NPC plugin, NPCMark42 is designed around behaviors, skills, combat, movement, spawning and interactions.
Create simple interactive NPCs, advanced guards, flying enemies, custom combat NPCs, personal companions, event NPCs, server selectors and much more — all from a powerful in-game GUI.
◆ WHY NPCMark42?

• GUI-FIRST MANAGEMENT — Configure NPCs without having to memorize dozens of commands.
• CUSTOM SKILLS — Give NPCs unique abilities and combat behaviors.
• ADVANCED MOVEMENT — Walking, chasing, patrolling, flying and more.
• COMBAT AI — Create NPCs that can defend, attack, protect and react to players.
• SPAWN SYSTEM — Create configurable NPC spawn points with intervals and limits.
• PLAYER-OWNED NPCs — Allow administrators to issue temporary NPCs to players.
• FRIEND SYSTEM — Owned NPCs can recognize trusted players and protect them.
• PROTECTION SUPPORT — Respect protected regions and anti-grief systems.
• DEVELOPER API — Build your own integrations, skills and behaviors.

◆ POWERFUL NPC SKILLS
NPCMark42 includes a modular skill system designed to make NPCs much more than static characters.

Category	Examples
⚔ Combat	Melee, Ranged, Projectile, Knockback, Area Attack
Abilities	Fireball, Lightning, Explosion, Poison, Freeze
Movement	Fly, Dash, Leap, Charge, Retreat
Targeting	Nearest Player, Hostile Players, Mobs, Custom Targets
Protection	Guard Owner, Protect Friends, Defend Area
✨ Utility	Heal, Shield, Teleport, Summon

Skills are designed as independent modules so additional abilities can be added without rebuilding the entire NPC system.
◆ FLYING & ADVANCED MOVEMENT
NPCMark42 is not limited to NPCs standing in one place.
Create NPCs that can fly, chase players through the air, perform dive attacks, retreat, reposition and return to their assigned area.

• Flying NPCs
• Elytra-style movement
• Dive attacks
• Dash abilities
• Leap attacks
• Chasing
• Retreat behavior
• Patrolling
• Guarding
• Follow behavior
• Return-to-spawn behavior

Movement and behavior can be configured through the NPC editor.
◆ COMBAT & WEAPON SUPPORT
NPCMark42 provides a flexible combat system that allows NPCs to use different attack styles and weapons.

• Swords
• Bows
• Crossbows
• Tridents
• Projectiles
• Custom attacks
• Custom skills
• External weapon integrations

The weapon integration system is designed to allow other weapon plugins to connect through an integration API instead of hard-coding a single dependency.
◆ NPC SPAWN POINTS
Need NPCs to appear automatically?
Create a spawn point and configure how NPCs are generated.

• Custom spawn locations
• Spawn intervals
• Maximum active NPCs
• Spawn amount
• Spawn radius
• World restrictions
• Player proximity requirements
• Time conditions
• Permission conditions

Example:
/npc spawnpoint create arena_guard
Then configure the spawn point through the GUI.
◆ PLAYER-OWNED NPCs
One of NPCMark42's major features is the ability for administrators to issue temporary NPCs to players.
An administrator can issue an NPC template or temporary NPC token to a player.
Example:
/npc give Alpha944 Guardian 1
The player receives an NPC that can be placed in the world.
Once placed:

• The player becomes the NPC owner.
• The NPC can protect its owner.
• The owner can interact with the NPC.
• The owner can manage trusted players if permitted.
• The NPC follows the limits configured by the administrator.

◆ OWNER & FRIEND SYSTEM
Player-owned NPCs can distinguish between their owner, trusted friends and hostile players.
Example:
/npc friends add PlayerName
Friends can be protected from the NPC's hostile targeting.
The NPC can be configured to:

• Protect the owner
• Protect friends
• Attack hostile players
• Attack hostile mobs
• Guard a location
• Return to the owner
• Return to its assigned area

All player-owned NPC abilities remain controlled by administrator-defined limits.
◆ HEALTH & DEATH SYSTEM
Player-owned NPCs can have their own configurable health.
Example:
Health: 100 HP
The NPC can display a health bar while taking damage.
When the NPC reaches zero health:

• The NPC dies.
• The entity is removed correctly.
• Its temporary NPC ID becomes invalid.
• The player cannot reuse the ID to create another NPC unless a new token is issued.

◆ ANTI-GRIEF & PROTECTION
NPCMark42 is designed to respect your server's protection systems.
NPCs should never be allowed to bypass your server's region or anti-grief rules.
The protection system is designed around an integration API for external protection plugins.
Administrators can also configure:

• Protected worlds
• Protected regions
• Allowed blocks
• Blocked blocks
• Interaction restrictions
• NPC damage restrictions

This allows server owners to give players useful NPC abilities without giving those NPCs unlimited access to the world.
◆ DIALOGUES & INTERACTIONS
NPCs can become interactive characters instead of simple decorations.
Create dialogue menus such as:
Support for:

• Multiple dialogue pages
• Commands
• Sounds
• Particles
• Permissions
• Conditions
• Placeholders
• Teleportation
• GUI actions
• Skill triggers

◆ POWERFUL ADMIN GUI
NPCMark42 is designed around a full in-game editor.
Administrators can manage NPCs without manually editing configuration files.
◆ DEVELOPER API
NPCMark42 is built with developers in mind.
The API is designed to allow other plugins to integrate directly with NPCMark42.
Developers will be able to work with:

• NPC creation
• NPC removal
• NPC modification
• Skills
• Behaviors
• Conditions
• Actions
• Weapon providers
• Protection providers
• NPC events

Example event types:
NPCInteractEvent
NPCDamageEvent
NPCDeathEvent
NPCTargetEvent
NPCSkillEvent
NPCBehaviorChangeEvent
◆ PERFORMANCE
NPCMark42 is designed for real production servers and networks.
The system avoids unnecessary work and is built around controlled processing rather than creating a thread for every NPC.

• Bounded task scheduling
• Cached NPC data
• Async database operations
• Controlled AI processing
• Efficient target scanning
• Distance-based activation
• Optimized pathfinding
• No thread per NPC
• No unnecessary chunk loading

Use:
/npc status
to inspect NPC and system information.
◆ COMMANDS

• /npc create <id> — Create an NPC.
• /npc remove <id> — Remove an NPC.
• /npc edit <id> — Open the NPC editor.
