Why does my body SLOWLY but SURELY inch forward with this script

[RuinedSanctuary]

-- this happens every renderstpped
Humanoid.AutoRotate = false
local pos = Root.Position
Root.CFrame = CFrame.new(pos)

it’s pretty simple to tell what this script is SUPPOSED to do but instead it SLOWLY makes my little HUMANOID inch forward and I have no idea why

[RuinedSanctuary]

for some reason my root thinks it’s neccessary to just “follow” my cameras movements in terms of rotation too which makes 0 sense

[ScriptingWhiz (bloke)]

It’s because your setting the Pos to the same position each frame

[RuinedSanctuary]

yeah but that shouldn’t make it go forward and that’s how this post does it (basically) and it used to not do this

How to make my character face to where the mouse is?

Hello! So, I’m trying to make an game with a RPG top-down camera view. I’m currently working on the aim aspect of the game where the character will face to the direction of where the mouse is. I mean like this: [image] I was thinking of making the HumanoidRootPart face mouse.Hit but I don’t really know how to implement it. Help or tips are greatly appreciated.

but I will try a different method

[Doomcolp (dxxmed)]

I’m not really sure about internals but maybe it’s something to do with rounding?

Like when you save the current position, it’s actually a really precise floating point number but it’s rounded up.

That’s all that I could possibly think of

You want your character to look at your mouse ?

[RuinedSanctuary]

this could be true so I did this instead

no I was just looking at that post anyway I want my character to look at camera lookvector + root position (same Y as root)

[RuinedSanctuary]

wait I forgot to actually reply this is whaat I did

local pos = Root.CFrame.Position
		local cpos = Camera.CFrame.LookVector*10

	Root.CFrame = CFrame.lookAt(pos, pos + Vector3.new(cpos.X, 0, cpos.Z))

it still makes me inch slitgly slower

[Doomcolp (dxxmed)]

Yeah honestly I don’t have any clue either. Shouldn’t be moving you at all according to that code snippet

[ScriptingWhiz (bloke)]

local cam = workspace.CurrentCamera
local hrp = char.HumanoidRootPart

local wantPos = hrp.Position + vector3.new(cam.CFrame.LookVector.X, 0, cam.CFrame.LookVector.Z)

hrp.CFrame = CFrame.new(hrp.Position, wantPos)

Try this also sorry abt the errors I’m on mobile

Perhaps try smoothing it a bit with lerp:

local Camera = game:GetService("Workspace").CurrentCamera
local Character = game:GetService("Players").LocalPlayer.Character
local Root = Character.HumanoidRootPart

game:GetService("RunService").RenderStepped:Connect(function()
	local look = Root.Position + Vector3.new(Camera.CFrame.LookVector.X, 0, Camera.CFrame.LookVector.Z)
	Root.CFrame = Root.CFrame:lerp(CFrame.new(Root.Position, look), 0.5)
end)

Edit: changing the lerp rate from 0.5 to 0.1 makes a really smooth turning animation.

[RuinedSanctuary]

local wantPos = Root.Position + Vector3.new(Camera.CFrame.LookVector.X, 0, Camera.CFrame.LookVector.Z)
		Root.CFrame = CFrame.new(Root.Position, wantPos)

yeah I did that and it still inches me forward I don’t know if this is a roblox bug or something at this point

[ScriptingWhiz (bloke)]

Can you send a video of this happening ?

[JayzYeah32]

Here’s a rewritten, alternative approach using a BodyGyro, instead of altering the CFrame directly:

local camera = game:GetService("Workspace").CurrentCamera
local player = game:GetService("Players").LocalPlayer
local character = player.Character
local root = character.HumanoidRootPart

character.Humanoid.AutoRotate = false

local gyro = Instance.new("BodyGyro")
gyro.MaxTorque = Vector3.new(0, math.huge, 0)
gyro.P = 10000
gyro.D = 200
gyro.CFrame = root.CFrame
gyro.Parent = root

game:GetService("RunService").RenderStepped:connect(function()
	local lookDirection = camera.CFrame.LookVector
	local flatDirection = Vector3.new(lookDirection.X, 0, lookDirection.Z).Unit
	local targetRotation = CFrame.new(Vector3.zero, flatDirection)

	gyro.CFrame = CFrame.new(root.Position) * CFrame.Angles(0, math.atan2(-flatDirection.X, -flatDirection.Z), 0)
end)

[RuinedSanctuary]

normally I would but I have to go quickly basically it would just make me face the correct direction but would move me forward like 0.01 studs every frame

my pc has 2 fps anyway yeah I just used this method

this probably would’ve worked too but I tried the gyro method and so far it works plus it’s customizable which is nice

anyway thanks for the help to eveyone

Also, it seems in my old games where this used to happen, it does not happen anymore. Now I’m actually sure this was a random Roblox bug or toggle that got fixed when Studio updated.
