Creating NPC (Non-Player Character) characters in Roblox can add a lot of fun and immersion to your game. NPCs can be used for a variety of purposes, such as quest givers, enemies, or simply background characters. Below is a step-by-step guide on how to create an NPC and give it basic functionality, such as interacting with the player and following them.
Steps to Create an NPC Character in Roblox:
1. Create the NPC Model
• Open Roblox Studio and load your game.
• You can create your own NPC model from scratch, or you can use the Roblox Toolbox to import an existing NPC model.
• To create your own NPC, start by adding parts (such as a Head, Torso, Arms, and Legs) to form the body.
• Make sure the NPC has a Humanoid object for movement and health (this is what makes it behave like a character).
• Add a Head part and a Humanoid to the model. The Humanoid gives the model health and allows it to move.
2. Add the NPC to the Game:
• In the Explorer window, create a new Model (right-click and select Insert Object > Model).
• Name the model “NPC” or anything you prefer.
• Inside the NPC Model, add the following parts:
• Head (a basic sphere or custom shape).
• Torso, Arms, and Legs (can be made from simple parts or meshes).
• Humanoid (this is a required part to allow the NPC to function like a character).
3. Adding the NPC Script:
Now, let’s write a simple script to make the NPC interactive and give it basic functionality, like following a player when they approach.
Basic NPC Script to Follow the Player:
1. In the Explorer window, right-click on your NPC model and insert a Script (right-click > Insert Object > Script).
2. Copy and paste the following script to make the NPC follow the player.
— Variables
local npc = script.Parent — The NPC Model
local humanoid = npc:WaitForChild(“Humanoid”) — The humanoid of the NPC
local targetPlayer = nil — The player the NPC will follow
local followDistance = 10 — Distance at which NPC will start following the player
local speed = 16 — Speed of NPC’s movement
— Function to make the NPC follow the player
local function followPlayer()
while true do
if targetPlayer and targetPlayer.Character then
local playerPos = targetPlayer.Character.HumanoidRootPart.Position — Player’s position
local npcPos = npc.HumanoidRootPart.Position — NPC’s position
— Move the NPC towards the player
humanoid:MoveTo(playerPos)
— If the NPC is within the following distance, stop following
if (npcPos – playerPos).Magnitude < followDistance then
humanoid:MoveTo(npcPos) — Stop moving
end
end
wait(0.5) — Check every half second
end
end
— Function to detect when a player is nearby
local function onPlayerNearby(player)
if player.Character and (npc.HumanoidRootPart.Position – player.Character.HumanoidRootPart.Position).Magnitude < followDistance then
targetPlayer = player — Set the target player to follow
followPlayer() — Start following the player
end
end
— Detect when players join the game
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(character)
onPlayerNearby(player) — Check if this player is nearby
end)
end)
— Detect when the NPC is close enough to follow the player
while true do
for _, player in pairs(game.Players:GetPlayers()) do
if player.Character then
onPlayerNearby(player) — Check every player for proximity
end
end
wait(1) — Check every second
end
What this script does:
• This script allows the NPC to follow a player when they come within a specific distance (10 studs by default).
• The NPC will move towards the player’s position using the MoveTo() function.
• The NPC stops following the player if they get within a certain distance.
• It continually checks for nearby players in the game and starts following them if they are within range.
4. Adding Interactions with the NPC (Quest or Talking System)
Now, let’s add a simple interaction system where the player can click on the NPC to trigger a message or start a quest.
1. Add another Script to the NPC (right-click on the NPC model and insert a new Script).
2. Paste the following code to allow interaction when the player clicks on the NPC.
NPC Interaction Script:
local npc = script.Parent — The NPC Model
local npcHumanoid = npc:WaitForChild(“Humanoid”)
local playerProximity = 10 — Distance to interact with NPC
local talking = false — Track if the NPC is already talking
— Function to start talking to the player
local function talkToPlayer(player)
if talking then return end
talking = true
— Create a simple dialog message
print(player.Name .. ” is talking to the NPC!”)
local dialogMessage = “Hello, ” .. player.Name .. “! How can I help you today?”
print(dialogMessage) — You can replace this with a GUI text box in the game for display.
— Wait for a few seconds before the NPC stops talking
wait(3)
talking = false
end
— Detect when the player is close enough to the NPC
npc.Touched:Connect(function(hit)
local character = hit.Parent
local player = game.Players:GetPlayerFromCharacter(character)
if player and (npc.HumanoidRootPart.Position – player.Character.HumanoidRootPart.Position).Magnitude < playerProximity then
talkToPlayer(player)
end
end)
What it does:
• When a player comes close to the NPC (within 10 studs), the NPC will start a simple dialog.
• This example just prints messages in the output. You can expand this by creating a GUI or a dialog system that pops up on the screen.
5. Adding NPC Quest System (Optional)
You can create a quest system where the NPC gives a task to the player, and the player can complete it for rewards. Here’s a simple example of adding a quest:
1. Create a Folder inside your NPC model and name it Quest (to organize the quest-related data).
2. Inside the Quest Folder, add a StringValue named QuestName (this will store the name of the quest).
3. Add a BoolValue inside the NPC’s model to track whether the quest is completed.
Simple Quest Script:
local npc = script.Parent
local questFolder = npc:WaitForChild(“Quest”)
local questName = questFolder:WaitForChild(“QuestName”)
local questCompleted = false
— Example of quest where the player needs to collect 3 items
local itemsToCollect = 3
local itemsCollected = 0
local function giveQuest(player)
if not questCompleted then
print(player.Name .. ” has received the quest: ” .. questName.Value)
— Tell the player what they need to do
— In a real game, you would use a GUI here to explain the quest
print(“Collect ” .. itemsToCollect .. ” items.”)
end
end
local function onItemCollected(player)
if not questCompleted then
itemsCollected = itemsCollected + 1
print(player.Name .. ” has collected an item. Total: ” .. itemsCollected)
— Check if player completed the quest
if itemsCollected >= itemsToCollect then
questCompleted = true
print(player.Name .. ” has completed the quest!”)
— Reward the player here
end
end
end
— Give the quest when the player interacts with the NPC
npc.Touched:Connect(function(hit)
local character = hit.Parent
local player = game.Players:GetPlayerFromCharacter(character)
if player then
giveQuest(player)
end
end)
— Example of item collection event
game.ReplicatedStorage.ItemCollected.OnServerEvent:Connect(function(player)
onItemCollected(player)
end)
What it does:
• The NPC will give the player a quest when they touch it.
• The player must collect items (this is just an example; you would need to set up actual items in your game).
• Once the player collects the required number of items, the NPC will reward them or mark the quest as completed.
Conclusion
By following these steps, you can create a simple NPC in Roblox that:
• Follows players.
• Interacts with players through a basic dialog.
• Gives quests and tracks progress.
You can expand upon these scripts by adding more complex behaviors like combat, trading, and quest tracking using GUIs. Don’t forget to create NPC models that suit the roles you want them to play in your game!
