Player look towards mouse stuck on parts

Help and Feedback Scripting Support
#1

The player currently looks towards the mouse, but sometimes stalls when the mouse goes over objects like walls and what not. I want the mouse to ignore all walls and everything and the player looks towards the mouse no matter what.

local player = game.Players.LocalPlayer
repeat wait() until player:GetMouse() and player.Character
local mouse = player:GetMouse()
local character = player.Character
local render = game:GetService("RunService")

local atan2, pi, dir, torso, torsoPos = math.atan2, math.pi

while true do
		render.RenderStepped:Wait()
		torso = character:FindFirstChild("HumanoidRootPart")
		if torso ~= nil then
			torsoPos = torso.Position
			dir = (mouse.Hit.p - torsoPos).unit
			torso.CFrame = CFrame.new(torsoPos) * CFrame.Angles(0, atan2(dir.X, dir.Z) + pi, 0)
		end
end

It may be worth mentioning this is an oldish script I had help making and for some reason the 7th line is underlined red, but everything still works.

PlayerMouse.Hit is a CFrame of where a ray from the PlayerMouse hit onto a Part.

You can infact get this ray normalised (from PlayerMouse.UnitRay) and therefore retrieve the Direction.

Perhaps try replacing mouse.Hit.p with mouse.UnitRay.Direction

Thanks for the reply. I tried your suggestion but it doesn’t seem to work. There are no errors, but the player just stops looking towards the mouse entirely.

#4

I think he meant to replace this part:
dir = (mouse.Hit.p - torsoPos).unit
with this:
dir = mouse.UnitRay.Direction

#5

Thanks that doesn’t seem to worth either though, but it does do something. The player looks towards the mouse but only when it’s on the upper half of the screen

#6

Instead of using atan2 maybe try using the two-vector constructor:

torso.CFrame = CFrame.new(torsoPos, torsoPos + dir * Vector3.new(1, 0, 1))

Or if you’d rather not use the deprecated constructor, use CFrame.fromMatrix()

dir = (mouse.UnitRay.Direction * Vector3.new(1, 0, 1)).Unit -- project onto XZ
local right = dir:Cross(Vector3.new(0, 1, 0))
local up = right:Cross(dir)
torso.CFrame = CFrame.fromMatrix(torsoPos, right, up)

Sorry i know it’s a late reply, but your top recommendation still gets the mouse stuck on parts, the other had the same problem as the one above where it only works a little bit when the mouse is on the top half of the screen, but also doesn’t seem to get stuck on parts. My game is in a fixed (mostly) top-down angle if that matters with this code (which i assumed it wouldn’t).

It’s alright. I didn’t know about the top-down component though, so that gave me an idea to use a raycast from the mouse’s position on the screen. Using a whitelist containing just the parts that make up the floor, you can get a position for a mouse hit that ignores walls and other obstacles.

-- uis = UserInputService
-- cam = CurrentCamera
-- hrp = HumanoidRootPart
pos = uis:GetMouseLocation()
ray = cam:ScreenPointToRay(pos.X, pos.Y - 36)
ray = Ray.new(ray.Origin, ray.Direction * 100)
part, pos = workspace:FindPartOnRayWithWhitelist(ray, {workspace.Baseplate})
if (part) then
	hrp.CFrame = CFrame.new(hrp.Position, Vector3.new(pos.X, hrp.Position.Y, pos.Z))
end

Here’s a test place I threw together in case you want to take apart the script I used:
