📙 Introduction to NPCSpawn Framework

NPCSpawn is a modern spawn management framework for NPCs and Nextbots in Garry's Mod. It fully replaces legacy systems such as npc_maker, info_npc_spawn_destination, and inherited spawn scripts by removing any dependency on physical entities required for operation.

Built on a 100 % virtual logic, NPCSpawn operates entirely in memory, without any fixed spawn points placed on the map. The result is fewer entities, fewer conflicts, and increased stability. Even NPCs and Nextbots benefit from a cleaner environment, as unnecessary elements are removed from their AI search space.

As the direct successor to Gmod NPCs Spawn Point Creator (2021), this 2026 version was designed for RP, PVE, sandbox, and scripted servers requiring precise control over NPC and Nextbot density, behavior, and rotation.

The system acts as a complete, gamemode-independent replacement, faster, cleaner, and fully focused on server optimization.

🧠 Dynamic and conditional spawn logic

NPCSpawn zones are entirely logical, calculated in real time, and free of any mapped entities.
Each zone controls NPC types, maximum quantities per zone, and their appearance or removal conditions.

Typical use cases:
-You can choose which NPCs can spawn during the day or at night (if NWeather is present in the installation).
-Patrol zones activated based on player presence.
-Adaptive respawn tied to scenarios or progression.
-Dynamic events, invasions, or enemy waves.
-Automatic rotation of spawn points to simulate reinforcements.

The complete absence of npc_maker and info_node entities drastically reduces server load, prevents duplication, and improves overall smoothness.

🔬 AI routine optimization through a non-physical entity architecture

In the Source engine, NPCs and Nextbots continuously analyze their environment to detect players, potential targets, or points of interest.
This scan is not limited to visible entities: all entities present on the map are evaluated, including invisible, non-interactive, or purely technical ones.

By completely removing physical entities related to spawn systems, NPCSpawn drastically reduces the number of entities evaluated during these scan phases.
Spawn functionality remains intact, as it is replaced by pure Lua logic, stored in memory and executed only when necessary.

This philosophy, applied across all my scripts, aims to preserve advanced features while eliminating unnecessary server-side entities.
The result is a measurable reduction in internal iterations, fewer useless AI calculations, and a direct improvement in server performance, especially in environments heavily populated with NPCs and Nextbots.

⚙️ NPCSpawn interface, centralized management

A single menu provides centralized and complete administration of spawn zones:
-Creation, editing, and removal of NPC and Nextbot zones.
-Definition of classes, models, weapons, factions, and AI behaviors.
-Advanced priority management, with per-NPC and per-spawn-group probability rates, removing the need to manually edit individual spawn points.
-Limitation of active entities per zone, as well as a global cap across the entire map.
-Automatic or manual triggering of spawns on a per-zone basis.
-Targeted removal of NPCs originating from a specific zone, without affecting NPCs spawned in other zones.

🧰 Real-time visual editing SWEP

A dedicated SWEP allows zones to be placed and modified directly in-game, without Hammer or native entities.
Zones can be cubic, spherical, flat, or volumetric, and adjusted instantly.

Controls:
-Reload: tool main menu.
-Left click: P1 point.
-Right click: P2 point and volume creation.
-Left click on zone: move.
-Right click on zone: delete.
-Buttons in the top-left corner to switch between other build tools.

Features:
-3D admin ESP visualization of zones.
-Fixed or random spawn direction.

🎯 Advanced spawn filters and conditions

Each zone can precisely filter entities:
-Specific NPC or Nextbot classes.
-Spawn orientation and angle.
-Logical conditions: player presence, timer, Lua trigger (distance-based).

📜 Expert configuration and priorities

NPCSpawn provides fine-grained per-zone control:
-Simultaneous NPC limits.
-Configurable respawn delay.
-Random or targeted rotation between zones.
-Activation via logic, command, or event.
-Exclusion zones to prevent abusive spawning near players.

🌪️ Server optimizations and removal of native spawns

🌪️ Optimization #1
Automatic removal at startup of native spawn entities (npc_maker, ai_goal_*, info_npc_spawn_destination).

Benefits:
-Lighter server environment.

🌪️ Optimization #2
Zones can be automatically enabled or disabled based on player proximity, using a configurable detection radius, reducing unnecessary calculations. This is useful if you want NPCs only where actual activity occurs on your server. Poorly optimized NPCs should not exist in inactive areas.

🌪️ Optimization #3
Automatic despawn of NPCs in inactive zones, significantly reducing CPU load.

🧩 Norda Suite, a modular ecosystem for map building

NPCSpawn Framework is a natural extension of the lineup and further strengthens an ecosystem already designed for clean, modular, and high-performance map building on GMod. It works in perfect synergy with NPlayerSpawn for advanced player spawn management, NRestrict for precise zone access control, NSafeZone for optimized area security, NSoundscape Creator for custom soundscape creation, and GhostEntity for high-performance map decoration.

The objective is simple, to provide a coherent and interconnected toolset that accelerates the creation of solid, readable, and fully optimized maps, while maintaining a clean and controlled workflow.
