As the title says, im trying to make the player face the nearest enemy. Im working on a combat system and i want to be able to run up to an NPC and automatically face him.
What im trying to achieve is the ability to run up to an NPC and not have to worry about aiming your mouse while swinging your sword. Kind of like some auto lock feature i guess. Any help is greatly appreciated!
You could try setting the character’s HumanoidRootPart’s CFrame
Since the CFrame.new constructor can take a position and a “lookAt”, you can do something like this:
rootPart.CFrame = CFrame.new(rootPart.Position, enemyRoot.Position)
You can do the following
local function getNearestNPC(character, npcsFolder) -- Your character and the folder containing all the NPCs
local rootPart = character:FindFirstChild("HumanoidRootPart")
local rootPosition = rootPart.CFrame.Position
local bestNPC
local maxDistance = math.huge -- Change it to the maximum distance you want an NPC to be
for _, model in next, npcsFolder:GetChildren() do
if model:IsA("Model") and model:FindFirstChild("HumanoidRootPart") then
local distance = (model.HumanoidRootPart.CFrame.Position - rootPosition).Magnitude
if distance < maxDistance then
maxDistance = distance
bestNPC = model
end
end
end
return bestNPC, maxDistance
end
game:GetService("RunService").RenderStepped:Connect(function()
local closestNPC, closestDistance = getNearestNPC(YOUR_CHARACTER, NPC_FOLDER)
if closestNPC then
local rootCFrame = YOUR_CHARACTER.HumanoidRootPart.CFrame
local targetCFrame = closestNPC.HumanoidRootPart.CFrame
YOUR_CHARACTER:PivotTo(CFrame.new(rootCFrame.Position, targetCFrame.Position))
end
end)

Hello, Would you tell me where i should put this script? and What you meant by “Your Character”.
I just started scripting so i got confused here
Just use lookAt. It’s as simple as that.
YOUR_CHARACTER can be defined as your player’s model.
local PlayerService = game:GetService("Players")
local localPlayer = PlayerService.LocalPlayer
if not localPlayer.Character then
localPlayer.CharacterAdded:Wait()
end
local YOUR_CHARACTER = localPlayer.Character
oh ok. And where should i put this script? Like in starterplayer or somewhere else.
You can put that in StarterGui. I guess it will work just fine.
Here’s an example script in Lua for Roblox that should achieve the auto-lock feature you’re looking for:
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local detectionRadius = 10
local target = nil
function findNearestEnemy()
local enemies = game.Workspace:GetChildren()
local minDistance = math.huge
local nearestEnemy = nil
for i, enemy in ipairs(enemies) do
if enemy:IsA("Model") and enemy:FindFirstChild("Humanoid") and enemy.Humanoid.Health > 0 then
local distance = (enemy.HumanoidRootPart.Position - player.Character.HumanoidRootPart.Position).magnitude
if distance < minDistance and distance <= detectionRadius then
minDistance = distance
nearestEnemy = enemy
end
end
end
return nearestEnemy
end
function rotatePlayerToTarget()
if target then
local direction = target.HumanoidRootPart.Position - player.Character.HumanoidRootPart.Position
local angle = math.atan2(direction.z, -direction.x)
player.Character.HumanoidRootPart.CFrame = CFrame.new(player.Character.HumanoidRootPart.Position) * CFrame.Angles(0, angle, 0)
end
end
function onMouseClick()
target = findNearestEnemy()
rotatePlayerToTarget()
end
mouse.Button1Down:Connect(onMouseClick)
This script first defines the detection radius and initializes the target variable to nil. The findNearestEnemy() function loops through all objects in the game’s Workspace and finds the nearest enemy within the detection radius. The rotatePlayerToTarget() function calculates the angle between the player’s forward vector and the direction to the target enemy, then rotates the player towards the target. Finally, the onMouseClick() function is called when the player clicks their left mouse button, and it sets the target variable to the nearest enemy and rotates the player towards the target.
Hello Holis, I tried using this and made it work for my game but it doesn’t seem to work… this is what i did. made a local script inside STarterGUI and pasted the script inside. did i do something wrong?
Is there a way to make it so that the camera turns with the player? (sorry for all these questions homie)
Yeah, however it will get very complicated to manipulate if you don’t have experience with how roblox works. You can try to read the documentation and watch tutorials on YT. I am pretty sure that it will be helpful for you
