How would I start on a sensitivity script?

Hello DevForum,
I’m making a paintball game by myself currently, and I’m trying to figure out how I would make a mouse sensitivity script. I’ve been trying to think about how to start for a couple of hours, but I have no idea how to start. Heres my attempt :

rs.RenderStepped:connect(function()
   cam.CFrame = cam.CFrame:Lerp(CFrame.new(cam.CFrame.p, mouse.hit.p), Sensitivity*0.01)
end)

As you can see, it’s not a very good script. All it does is make the camera turn. I’m trying to make a sensitivity script like in one of my favorite Roblox games of all time, Nerf FPS.

I have a feeling MouseDeltaSensitivity would work, but I’ve tried, I couldn’t figure that out.

I would suggest using the GetMouseDelta() from the UserInputService or any way of getting how much the mouse moves. You can then set the camera’s cframe like so:

local Delta = UserInputService:GetMouseDelta()
rs.RenderStepped:Connect(function()
    cam.CFrame = cam.CFrame * CFrame.Angles(0, math.rad(0, (Delta.X * 0.01) * (Sensitivity * 0.01)
end)

This came from the top of my head so sorry if anything is wrong about it.

workspace.CurrentCamera.CameraType = Enum.CameraType.Custom

local Sensitivity = 3
local UserInputService = game:GetService("UserInputService")
local rs = game:GetService("RunService")
local cam = workspace.CurrentCamera

local Delta = UserInputService:GetMouseDelta()
rs.RenderStepped:Connect(function()
	local DeltaX = math.rad((Delta.X * 0.01)*(Sensitivity*0.01))
	local DeltaY = math.rad((Delta.Y * 0.01)*(Sensitivity*0.01))
	
	print(DeltaX)
    cam.CFrame = cam.CFrame * CFrame.Angles(0, DeltaX, 0)
end)

It didn’t work. It always printed 0 in the output.

Oops sorry forgot to mention UserInputService.MouseBehavior has to be set to Enum.MouseBehavior. LockCenter. With this method, you can actually incorporate MouseDeltaSensitivity into this now.

Make sure the camera is scriptable and you have mouse locked to center. (these are a must).

Then get the delta of the mouse every frame and multiply that by the sensitivity. (I usually multiply delta by 0.2 to start anyway).

(Here’s what I do)

Add the delta to a rotx and roty variable and then use than in the angular rotation of the camera.

Then offset the camera based on a object such as HumanoidRootPart then use a CFrame Offset for the Head such as 0,2,0 then multiply by rotX then rotY.

This is sample code:

local rotX, rotY = 0,0
local min,max = math.rad(-80),math.rad(80)
game:GetService("RunService").RenderStepped:Connect(function()
    --get Delta using GetMouseDelta, I use an outdated method in getting it...
    rotX = rotX - math.rad(deltaX)
    rotY = math.min(math.max(rotY - math.rad(deltaY), min), max)
    camera.CFrame = 
	CFrame.new(rootPart.Position) *
	CFrame.new(0, 4, 0) *
	CFrame.Angles(0, rotX, 0) *
	CFrame.Angles(rotY, 0, 0)
end)
