local animations = {}
local priorities = {
    Combat = 100,
    Interaction = 50,
    Movement = 30,
    Idle = 10
}

function AnimationController:LoadAnimations(character)
    -- Load all animation objects
    animations.Idle = character.Humanoid:LoadAnimation(idleAnimation)
    animations.Walk = character.Humanoid:LoadAnimation(walkAnimation)
    animations.Attack = character.Humanoid:LoadAnimation(attackAnimation)
end

function AnimationController:ChangeState(newState, priority)
    if priority >= priorities[currentState] then
        animations[currentState]:Stop()
        currentState = newState
        animations[newState]:Play()
    end
end

Lua is the scripting language that powers all interactive behavior in Roblox. For NPC development, understanding Lua deeply enables you to create characters that think, react, and behave in ways that feel intelligent and engaging to players.

Essential Lua Concepts for NPC Development:

Variables and Data Structures:
Understanding how to store and manipulate data is fundamental to creating NPCs that can remember information and make decisions based on their state.

-- NPC State Management Example
local npcData = {
    name = "Shop Keeper",
    health = 100,
    position = Vector3.new(0, 0, 0),
    currentState = "idle",
    inventory = {
        coins = 50,
        items = {"sword", "potion", "map"}
    },
    dialogueProgress = 1,
    lastPlayerInteraction = nil
}

Functions and Modular Programming:
Creating reusable functions allows you to build complex NPC behaviors from simple, testable components.

-- Modular NPC Behavior Functions
local NPCBehavior = {}

function NPCBehavior.greetPlayer(npc, player)
    local greeting = "Hello, " .. player.Name .. "!"
    npc.DisplayName = greeting
    -- Trigger greeting animation
    npc.AnimationController:PlayAnimation("Greeting")
end

function NPCBehavior.checkPlayerDistance(npc, player, maxDistance)
    local distance = (npc.HumanoidRootPart.Position - player.HumanoidRootPart.Position).Magnitude
    return distance <= maxDistance
end

function NPCBehavior.updateState(npc, newState)
    npc.CurrentState = newState
    -- Log state changes for debugging
    print(npc.Name .. " state changed to: " .. newState)
end

Control Structures for Decision Making:
NPCs need to make decisions based on changing conditions. Lua's control structures enable complex decision trees.

-- Decision Making Example
function NPCBehavior.decideBehavior(npc, nearbyPlayers)
    if #nearbyPlayers == 0 then
        -- No players nearby, perform idle behavior
        NPCBehavior.updateState(npc, "idle")
        NPCBehavior.performIdleBehavior(npc)
    elseif #nearbyPlayers == 1 then
        -- One player nearby, engage in interaction
        NPCBehavior.updateState(npc, "interacting")
        NPCBehavior.greetPlayer(npc, nearbyPlayers[1])
    else
        -- Multiple players, prioritize based on criteria
        local priorityPlayer = NPCBehavior.selectPriorityPlayer(nearbyPlayers)
        NPCBehavior.interactWithPlayer(npc, priorityPlayer)
    end
end

Event-Driven Programming:
Roblox NPCs respond to events in the game world. Understanding event handling is crucial for creating responsive characters.

-- Event Handling for NPC Interactions
local Players = game:GetService("Players")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Player proximity detection
local function onPlayerAdded(player)
    player.CharacterAdded:Connect(function(character)
        local humanoidRootPart = character:WaitForChild("HumanoidRootPart")
        
        -- Create proximity detection
        local proximityLoop
        proximityLoop = game:GetService("RunService").Heartbeat:Connect(function()
            if NPCBehavior.checkPlayerDistance(npc, character, 10) then
                NPCBehavior.onPlayerApproach(npc, player)
            end
        end)
        
        -- Clean up when character is removed
        character.AncestryChanged:Connect(function()
            if not character.Parent then
                proximityLoop:Disconnect()
            end
        end)
    end)
end

Players.PlayerAdded:Connect(onPlayerAdded)

Roblox-Specific Programming Concepts:

Services and APIs:
Roblox provides numerous services that NPCs can use to interact with the game world.

-- Essential Services for NPC Development
local PathfindingService = game:GetService("PathfindingService")
local TweenService = game:GetService("TweenService")
local RunService = game:GetService("RunService")
local SoundService = game:GetService("SoundService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")

-- Using services for NPC behavior
function NPCBehavior.moveToPosition(npc, targetPosition)
    local humanoid = npc.Humanoid
    local rootPart = npc.HumanoidRootPart
    
    -- Create pathfinding request
    local path = PathfindingService:CreatePath({
        AgentRadius = 2,
        AgentHeight = 5,
        AgentCanJump = true,
        WaypointSpacing = 4
    })
    
    -- Compute path and move NPC
    path:ComputeAsync(rootPart.Position, targetPosition)
    local waypoints = path:GetWaypoints()
    
    for i, waypoint in ipairs(waypoints) do
        humanoid:MoveTo(waypoint.Position)
        humanoid.MoveToFinished:Wait()
    end
end

Creating intelligent NPC behavior requires combining Lua programming skills with game design principles to produce characters that enhance the player experience through meaningful interactions.

State Machine Implementation:

State machines provide the organizational structure for complex NPC behavior, allowing characters to transition between different behavioral modes based on changing conditions.

-- Comprehensive NPC State Machine
local NPCStateMachine = {}
NPCStateMachine.__index = NPCStateMachine

function NPCStateMachine.new(npc)
    local self = setmetatable({}, NPCStateMachine)
    self.npc = npc
    self.currentState = "idle"
    self.states = {}
    self.stateTransitions = {}
    self.stateData = {}
    
    return self
end

function NPCStateMachine:addState(stateName, enterFunction, updateFunction, exitFunction)

AI Decision Making:

Implementing AI decision-making systems enables NPCs to respond intelligently to complex game situations.

-- AI Decision Making System
local AIDecisionSystem = {}

function AIDecisionSystem.evaluateOptions(npc, availableActions)
    local bestAction = nil
    local bestScore = -math.huge
    
    for _, action in ipairs(availableActions) do
        local score = AIDecisionSystem.calculateActionScore(npc, action)
        if score > bestScore then
            bestScore = score
            bestAction = action
        end
    end
    
    return bestAction
end

function AIDecisionSystem.calculateActionScore(npc, action)
    local score = 0
    
    -- Evaluate action based on NPC's current needs
    if action.type == "heal" and npc.Humanoid.Health < 50 then
        score += 100 -- High priority when health is low
    elseif action.type == "attack" and npc.CurrentTarget then
        local distance = (npc.HumanoidRootPart.Position - npc.CurrentTarget.Position).Magnitude
        score += math.max(0, 50 - distance) -- Closer targets are more attractive
    elseif action.type == "patrol" and not npc.CurrentTarget then
        score += 20 -- Default behavior when nothing else to do
    end
    
    -- Add randomness to prevent predictable behavior
    score += math.random(-10, 10)
    
    return score
end

function AIDecisionSystem.executeAction(npc, action)
    if action.type == "move" then
        NPCBehavior.moveToPosition(npc, action.targetPosition)
    elseif action.type == "attack" then
        NPCBehavior.performAttack(npc, action.target)
    elseif action.type == "interact" then
        NPCBehavior.interactWithObject(npc, action.object)
    end
end

Module 5: Advanced AI and Pathfinding Systems

Learning Objectives:

Master Roblox's PathfindingService for creating intelligent NPC navigation systems
Implement sophisticated behavior trees that enable complex AI decision-making
Develop obstacle avoidance and dynamic pathfinding algorithms for realistic movement
Create coordinated AI systems that enable multiple NPCs to work together effectively

PathfindingService is Roblox's built-in solution for intelligent navigation, enabling NPCs to move through complex environments while avoiding obstacles and finding optimal routes to their destinations.

PathfindingService Fundamentals:

Understanding the core concepts of Roblox's pathfinding system is essential for creating NPCs that can navigate your game world intelligently.

Basic Pathfinding Setup:

local PathfindingService = game:GetService("PathfindingService")
local RunService = game:GetService("RunService")

local NPCPathfinding = {}

function NPCPathfinding.createPath(agentParameters)
    -- Configure pathfinding parameters for different NPC types
    local defaultParams = {
        AgentRadius = 2,        -- Width of the NPC
        AgentHeight = 5,        -- Height of the NPC
        AgentCanJump = true,    -- Whether NPC can jump over obstacles
        WaypointSpacing = 4,    -- Distance between waypoints
        Costs = {
            Water = 20,         -- Higher cost for water areas
            Grass = 1,          -- Normal cost for grass
            Rock = 10           -- Higher cost for rocky terrain
        }
    }
    
    -- Merge custom parameters with defaults
    for key, value in pairs(agentParameters or {}) do
        defaultParams[key] = value
    end
    
    return PathfindingService:CreatePath(defaultParams)
end

function NPCPathfinding.moveToTarget(npc, targetPosition, callback)
    local humanoid = npc:FindFirstChild("Humanoid")
    local rootPart = npc:FindFirstChild("HumanoidRootPart")
    
    if not humanoid or not rootPart then
        warn("NPC missing required components for pathfinding")
        return false
    end
    
    -- Create path with NPC-specific parameters
    local path = NPCPathfinding.createPath({
        AgentRadius = npc:GetAttribute("AgentRadius") or 2,
        AgentHeight = npc:GetAttribute("AgentHeight") or 5
    })
    
    -- Attempt to compute path
    local success, errorMessage = pcall(function()
        path:ComputeAsync(rootPart.Position, targetPosition)
    end)
    
    if not success then
        warn("Pathfinding failed: " .. tostring(errorMessage))
        return false
    end
    
    -- Check if path was found
    if path.Status == Enum.PathStatus.Success then
        NPCPathfinding.followPath(npc, path, callback)
        return true
    else
        warn("No path found: " .. tostring(path.Status))
        return false
    end
end

function NPCPathfinding.followPath(npc, path, callback)
    local humanoid = npc:FindFirstChild("Humanoid")
    local waypoints = path:GetWaypoints()
    
    -- Store pathfinding data on NPC for management
    npc:SetAttribute("IsPathfinding", true)
    npc:SetAttribute("CurrentWaypointIndex", 1)
    
    for i, waypoint in ipairs(waypoints) do
        if not npc:GetAttribute("IsPathfinding") then
            break -- Pathfinding was cancelled
        end
        
        -- Handle different waypoint types
        if waypoint.Action == Enum.PathWaypointAction.Jump then
            humanoid.Jump = true
        end
        
        -- Move to waypoint
        humanoid:MoveTo(waypoint.Position)
        
        -- Wait for movement completion or timeout
        local moveConnection
        local timeoutConnection
        local completed = false
        
        moveConnection = humanoid.MoveToFinished:Connect(function(reached)
            completed = true
            if moveConnection then moveConnection:Disconnect() end
            if timeoutConnection then timeoutConnection:Disconnect() end
        end)
        
        -- Timeout after 5 seconds to prevent infinite waiting
        timeoutConnection = game:GetService("Debris"):AddItem(script, 5)
        wait(0.1) -- Small delay to allow movement to start
        
        -- Wait for completion
        while not completed and npc:GetAttribute("IsPathfinding") do
            wait(0.1)
        end
        
        npc:SetAttribute("CurrentWaypointIndex", i + 1)
    end
    
    -- Cleanup pathfinding state
    npc:SetAttribute("IsPathfinding", false)
    npc:SetAttribute("CurrentWaypointIndex", 0)
    
    -- Execute callback if provided
    if callback then
        callback(npc, path.Status == Enum.PathStatus.Success)
    end
end

Advanced Pathfinding Techniques:

Dynamic Pathfinding:
Create systems that recalculate paths when conditions change, such as new obstacles or moving targets.

function NPCPathfinding.createDynamicFollower(npc, target, updateInterval)
    local connection
    local lastTargetPosition = target.Position
    local currentPath = nil
    
    local function updatePath()
        local targetPosition = target.Position
        local distanceMoved = (targetPosition - lastTargetPosition).Magnitude
        
        -- Recalculate path if target moved significantly
        if distanceMoved > 10 then
            -- Cancel current pathfinding
            npc:SetAttribute("IsPathfinding", false)
            
            -- Start new pathfinding
            NPCPathfinding.moveToTarget(npc, targetPosition, function()
                -- Path completed callback
                print(npc.Name .. " reached target")
            end)
            
            lastTargetPosition = targetPosition
        end
    end
    
    -- Start initial pathfinding
    updatePath()
    
    -- Set up periodic updates
    connection = RunService.Heartbeat:Connect(function()
        wait(updateInterval or 2) -- Update every 2 seconds by default
        updatePath()
    end)
    
    -- Return cleanup function
    return function()
        npc:SetAttribute("IsPathfinding", false)
        if connection then
            connection:Disconnect()
        end
    end
end

Obstacle Avoidance:
Implement local avoidance for dynamic obstacles that PathfindingService might not handle effectively.

function NPCPathfinding.implementLocalAvoidance(npc, avoidanceRadius)
    local rootPart = npc:FindFirstChild("HumanoidRootPart")
    local humanoid = npc:FindFirstChild("Humanoid")
    
    if not rootPart or not humanoid then return end
    
    local function getAvoidanceVector()
        local avoidanceVector = Vector3.new(0, 0, 0)
        local obstacles = {}
        
        -- Detect nearby obstacles
        local region = Region3.new(
            rootPart.Position - Vector3.new(avoidanceRadius, 5, avoidanceRadius),
            rootPart.Position + Vector3.new(avoidanceRadius, 5, avoidanceRadius)
        )
        
        local parts = workspace:ReadVoxels(region, 4)
        
        for _, part in ipairs(parts) do
            if part ~= rootPart and part.CanCollide then
                local directionAway = (rootPart.Position - part.Position).Unit
                local distance = (rootPart.Position - part.Position).Magnitude
                local strength = math.max(0, (avoidanceRadius - distance) / avoidanceRadius)
                
                avoidanceVector = avoidanceVector + (directionAway * strength)
            end
        end
        
        return avoidanceVector.Unit * math.min(avoidanceVector.Magnitude, 1)
    end
    
    -- Apply avoidance during movement
    local connection = RunService.Heartbeat:Connect(function()
        if npc:GetAttribute("IsPathfinding") then
            local avoidanceVector = getAvoidanceVector()
            if avoidanceVector.Magnitude > 0.1 then
                -- Apply avoidance force
                local bodyVelocity = rootPart:FindFirstChild("BodyVelocity")
                if not bodyVelocity then
                    bodyVelocity = Instance.new("BodyVelocity")
                    bodyVelocity.MaxForce = Vector3.new(4000, 0, 4000)
                    bodyVelocity.Parent = rootPart
                end
                
                bodyVelocity.Velocity = avoidanceVector * 16 -- Avoidance speed
            end
        end
    end)
    
    return connection
end

Behavior trees provide a powerful framework for creating complex AI that can handle multiple priorities, react to changing conditions, and make intelligent decisions based on current context.
