Rotating Character towards mouse but not choppy

[Quoteory]

My goal is to have the character look at the mouse smoothly and consistently

the issue is that if a player hovers over different objects the rotation can get choppy

local RunService = game:GetService("RunService")

local player = game.Players.LocalPlayer
local character = script.Parent
local primary = character.PrimaryPart
local mouse = player:GetMouse()
mouse.TargetFilter = character

local bodyGyro = Instance.new("BodyGyro")
bodyGyro.Parent = primary
bodyGyro.D = 40
bodyGyro.P = 10000
bodyGyro.MaxTorque = Vector3.new(4000000, 4000000, 4000000)

while true do
	
	local mousePos = mouse.Hit.Position
	local primaryPos = primary.Position
		
	local lookatPos = Vector3.new(mousePos.X, primaryPos.Y, mousePos.Z)
	bodyGyro.CFrame = CFrame.new(primaryPos, lookatPos)
	
	RunService.Heartbeat:Wait()
	
end

I know a solution to this is to make a new ray and have an ignore list, but I’d rather not have to add things to a list every time I update the map, or update a whitelist if I go that route

is there a way to do this without mouse.Hit, or a way to make mouse.Hit work properly without a ignore/whitelist?

Reduce bodyGyro.P

This determines how aggressively the player tries to rotate.

the issue still exists, it just turns slower

You want to ignore players entirely?

I really want to ignore everything and just have the character look towards the direction of the mouse and not towards parts

The reason for the snap is that you are relying on mouse.Hit.Position which will ‘snap’ when your mouse hovers over different parts.

[0x_7777]

Here is your solution:
Calculate a 3D ray from 2D camera origin and mouse position. With your mouse ray, calculate the ray-plane intersection from the plane formed by the characters y-position. Just give a normal going straight up if the character is assumed to always be standing upright. Use the plane intersection position as the ‘looking’ direction.

Here is your code:

local Camera = workspace.CurrentCamera
local Player = game:GetService("Players").LocalPlayer
local Mouse = Player:GetMouse()
local RunService = game:GetService("RunService")

wait(0.5)

local player = game.Players.LocalPlayer
local character = player.Character
local primary = character.PrimaryPart

local bodyGyro = Instance.new("BodyGyro")
bodyGyro.Parent = primary
bodyGyro.D = 40
bodyGyro.P = 10000
bodyGyro.MaxTorque = Vector3.new(4000000, 4000000, 4000000)

local function rayPlane(planepoint, planenormal, origin, direction)
	return -((origin-planepoint):Dot(planenormal))/(direction:Dot(planenormal))
end

while true do
	local ray = Camera:ScreenPointToRay(Mouse.X, Mouse.Y)
	local t = rayPlane(Player.Character.Head.Position, Vector3.new(0, 1, 0), ray.Origin, ray.Direction)
	
	local primaryPos = primary.Position
		
	local plane_intersection_point = (ray.Direction * t) + ray.Origin
	bodyGyro.CFrame = CFrame.new(primaryPos, plane_intersection_point)
	
	RunService.Heartbeat:Wait()
	
end

exactly what I needed thanks a lot, works like a charm

to anyone looking at the post for the same issue, if you want the character to only look towards the x and z position you can do

bodyGyro.CFrame = CFrame.new(primaryPos, Vector3.new(plane_intersection_point.X, primaryPos.Y, plane_intersection_point.Z))

Sorry to bump this post but after trying your code out I noticed that if I aim in the sky or somewhere very far away my character looks in the opposite direction. Any idea why?

[cs_zr (CFrame)]

how would I format the script in order to add that?

[Quoteory]

local Camera = workspace.CurrentCamera
local Player = game:GetService("Players").LocalPlayer
local Mouse = Player:GetMouse()
local RunService = game:GetService("RunService")

wait(0.5)

local player = game.Players.LocalPlayer
local character = player.Character
local primary = character.PrimaryPart

local bodyGyro = Instance.new("BodyGyro")
bodyGyro.Parent = primary
bodyGyro.D = 40
bodyGyro.P = 10000
bodyGyro.MaxTorque = Vector3.new(4000000, 4000000, 4000000)

local function rayPlane(planepoint, planenormal, origin, direction)
	return -((origin-planepoint):Dot(planenormal))/(direction:Dot(planenormal))
end

while true do
	local ray = Camera:ScreenPointToRay(Mouse.X, Mouse.Y)
	local t = rayPlane(Player.Character.Head.Position, Vector3.new(0, 1, 0), ray.Origin, ray.Direction)
	
	local primaryPos = primary.Position
		
	local plane_intersection_point = (ray.Direction * t) + ray.Origin
	bodyGyro.CFrame = CFrame.new(primaryPos, Vector3.new(plane_intersection_point.X, primaryPos.Y, plane_intersection_point.Z))
	
	RunService.Heartbeat:Wait()
	
end

I think this was it, but it’s been a long time so I don’t remember clearly

and @Paintertable sorry for the late response, I do not sorry
@jody7777 wrote that bit of code, so if you still need help they would be one the to ask

[cs_zr (CFrame)]

is this code for the “x” and “z” axis only?, because thats all I want
