Prowl
One server script drives every NPC. Tag a rigged model, pick Chase, Guard, Patrol, Wander or Idle — no per-NPC scripts.
What you get
A global path budget means pathfinding can never melt the server. Stuck recovery jumps, re-paths, sidesteps, then reports blocked instead of standing in a wall.
How it holds up
Measured in Studio: 40 NPCs behind a wall, 32 paths in 8 seconds at a global budget of 8 paths per second.
What it does not do
Prowl drives NPCs you already rigged — it ships no rigs and no animations of its own, and it needs a rigged model to tag. It is a runtime layer on top of Roblox's PathfindingService, not a replacement for it. Offline, no telemetry.
The listing, word for word
Build useful NPC behavior without rebuilding the AI foundation.
Prowl is a Roblox Studio NPC AI plugin that turns a usable Humanoid rig into a configurable server NPC: Select a rig → choose a behavior → Create NPC → Play.
Five behaviors: • Chase — detect and pursue players • Guard — protect a home zone and return • Patrol — follow an ordered route • Wander — roam inside a set area • Idle — hold position
For horror, survival, RPG, stealth and enemy AI workflows.
Why Prowl: • One shared server runtime—no Prowl script in every NPC • Direct movement when safe; Roblox pathfinding when needed • Recovery, Quick Start and actionable diagnostics • Undo/Redo for supported actions • R6 and R15 tested on v0.2.1 • Simple server-side attack settings • No HTTP, backend or telemetry
Bring your own Humanoid rig and animations. Prowl is not a rig creator, animation system or full combat framework. Migration from v0.1 is manual.
