Advanced NPCs is a modular C++ and Blueprint-accessible NPC framework for Unreal Engine 5.7, designed to help developers build configurable NPC behaviour without recreating the same AI foundation for every character.

The plugin separates NPC logic into reusable systems for Brain, Movement, Presentation, world interaction, spawning, and debugging, while continuing to use Unreal Engine's existing AI Controller, Character Movement, NavMesh, and animation systems.

Core Features

• Modular Brain System — Attributes, Emotion, Personality, Conditions, Capabilities, and higher-level Intents.

• Intent System — Create reusable Intent Blueprints with Conditional or Manual activation, Continuous or One Shot execution, priorities, interruption rules, cooldowns, entry/exit conditions, parameters, and per-NPC overrides.

• Movement Behaviours — Built-in Idle, Wander, Follow, Flee, and Patrol behaviours with priorities, conditions, interruption rules, movement speeds, runtime control, and navigation support.

• Patrol System — Author reusable Patrol Routes and Patrol Points with route modes, waypoint-specific speeds, waiting, facing options, and editor visualization.

• Spawner Volume — Spawn NPC populations from configured templates with weighted NPC types, variants, presentation/state overrides, placement filters, NavMesh projection, respawning, and population limits.

• Modifier Volume — Create world-space areas that can pause or modify movement, affect Attributes and Emotion, evaluate Conditions, filter NPCs by Actor Tags, and act as local or global navigation blockers.

• Presentation System — Reusable Presentation Assets for Skeletal Meshes, Animation Blueprints, or lightweight Idle/Walk/Run animation setups.

• Built-in Conditions — Attribute Compare, Emotion Compare, Personality Compare, Has Capability, Distance To Player, Can See Player, and Inside Modifier Volume.

• Editor Tooling — Custom Details panels, configuration cards, validation warnings, reusable assets, parameter editors, behaviour controls, and debugging workflows.

• Runtime Debugging — Optional overhead debugging for movement, Intents, Attributes, Emotion, Personality, Capabilities, and other live NPC state.

Designed for Reuse

Advanced NPCs is built around reusable assets and configurable systems. The same Conditions, Intent logic, Attribute Profiles, Capabilities, Presentation Assets, and movement configurations can be shared across civilians, enemies, companions, guards, workers, or other NPC types.

Developers can use only the systems they need or combine them into more complex NPC behaviour.

REQUIRED DEPENDENCY(Automatically activated)-

GameplayTagsEditor — Epic’s built-in Unreal Engine plugin, required only by the Advanced_NPCsEditor module for the custom Gameplay Tag picker. It is enabled automatically by the plugin descriptor. Packaged runtime builds do not depend on GameplayTagsEditor.
