Roblox NPC & AI Systems

When implementing AI systems, use these Roblox-specific patterns for performant and intelligent NPCs.

NPC Creation (CRITICAL: Use Modern Patterns)

NEVER build NPCs by manually creating Parts. Use HumanoidDescription + CreateHumanoidModelFromDescriptionAsync.

Creating NPCs with HumanoidDescription

local Players = game:GetService("Players")

-- Create a basic NPC
local function createNPC(config)
    local description = Instance.new("HumanoidDescription")
