Player rotation only is left or right depending on mouse position

Help and Feedback Scripting Support

hello!

I am making a character movement system for my game and I want players only to rotate in 0,90,0 or 0,-90,0 depending on the mouse position.

How do I make it?

Try:

local RunService = game:GetService("RunService")
local function rayPlate(OriginalPos, Origin, Direction)
	return -((Origin-OriginalPos):Dot(Vector3.new(0, 1, 0)))/(Direction:Dot(Vector3.new(0, 1, 0)))
end
local GetMouseVector = function()
	local Mouse = Player:GetMouse()
	local Camera = workspace.CurrentCamera
	local unitRayDirection = Camera:ScreenPointToRay(Mouse.X,Mouse.Y)
	return unitRayDirection
end
RunService.Heartbeat:Connect(function()
	local MouseRay = GetMouseVector()
	local GettedVector = MouseRay.Direction*rayPlate(Player.Character.Head.Position, MouseRay.Origin, MouseRay.Direction) + MouseRay.Origin
	HumanoidRootPart.CFrame = CFrame.lookAt(HumanoidRootPart.Position,Vector3.new(GettedVector.X,HumanoidRootPart.Position.Y,GettedVector.Z))
end)

It could be smoother:

local RunService = game:GetService("RunService")
local TweenService = game:GetService("TweenService")
local function rayPlate(OriginalPos, Origin, Direction)
	return -((Origin-OriginalPos):Dot(Vector3.new(0, 1, 0)))/(Direction:Dot(Vector3.new(0, 1, 0)))
end
local GetMouseVector = function()
	local Mouse = Player:GetMouse()
	local Camera = workspace.CurrentCamera
	local unitRayDirection = Camera:ScreenPointToRay(Mouse.X,Mouse.Y)
	return unitRayDirection
end
RunService.Heartbeat:Connect(function()
	local MouseRay = GetMouseVector()
	local GettedVector = MouseRay.Direction*rayPlate(Player.Character.Head.Position, MouseRay.Origin, MouseRay.Direction) + MouseRay.Origin
	--HumanoidRootPart.CFrame = CFrame.lookAt(HumanoidRootPart.Position,Vector3.new(GettedVector.X,HumanoidRootPart.Position.Y,GettedVector.Z))
	local tween2 = TweenService:Create(HumanoidRootPart, TweenInfo.new(0.35,Enum.EasingStyle.Linear), {CFrame = CFrame.lookAt(HumanoidRootPart.Position,Vector3.new(GettedVector.X,HumanoidRootPart.Position.Y,GettedVector.Z))})
	tween2:Play()
end)

I will give you a solution!

Thank you so so much!

Hello again and again

After looking at your script, I have made a new one base on your script, and it works! It actually very simple and I can make it myself if I know what CFrame.Lookat does and how to use it.

Thank you again, you are a big help to me.

I don’t understand why it doesn’t work for you, here is an example of using the script:
