Trying to make movable Security Camera System

[Bomby15801580]

I want to be able to simply move my camera in all 4 directions with the Ui buttons but the camera needs to keeps its flat orientation at all times.

No matter what I do, I can never get the orientation of the camera to stay flat at all times.
I have attached a video.

I have already tried multiple different solutions such as having a loop always set the orientation.

I tried fixing this a couple months ago and got no where so I have just come back to it to see if I could fix it with no success.

local player = game.Players.LocalPlayer
local button = script.Parent.View
local Camera = workspace.CurrentCamera
local NextCam = script.Parent.Next
local PrevCam = script.Parent.Prev
local Left = script.Parent.Directional.Left
local Right = script.Parent.Directional.Right
local Up = script.Parent.Directional.Up
local Down = script.Parent.Directional.Down

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local cameraCount = 0
local currentCameraIndex = 1
local cameras = {}
local initialOffset = CFrame.Angles(-math.rad(0), 0, 0)

for _, CameraModel in ipairs(game.Workspace.Cameras:GetDescendants()) do
	if CameraModel:IsA("Model") and CameraModel.Name == "Camera" then
		local cameraPart = CameraModel:FindFirstChild("Camera")
		if cameraPart and cameraPart:IsA("BasePart") then
			cameraCount = cameraCount + 1 
			local value = Instance.new("NumberValue")
			value.Parent = CameraModel
			value.Value = cameraCount
			value.Name = "CameraNumber"
			cameras[cameraCount] = cameraPart
		end
	end
end

local function switchToCamera(index)
	if cameras[index] then
		Camera.CameraType = Enum.CameraType.Scriptable
		Camera.CFrame = cameras[index].CFrame * initialOffset
		Camera.FieldOfView = 120
		print("Switched to Camera " .. index)
	else
		warn("Camera " .. index .. " not found.")
	end
end

local Viewing = false

local function synchronizeCamera()
	while Viewing do
		if cameras[currentCameraIndex] then
			Camera.CFrame = cameras[currentCameraIndex].CFrame
		end
		wait()
	end
end

local function rotateCamera(direction)
	local rotationSpeed = math.rad(1)
	if cameras[currentCameraIndex] then
		local rotation = CFrame.new()
		if direction == "Up" then
			rotation = CFrame.Angles(-rotationSpeed, 0, 0)
		elseif direction == "Down" then
			rotation = CFrame.Angles(rotationSpeed, 0, 0)
		elseif direction == "Right" then
			rotation = CFrame.Angles(0, -rotationSpeed, 0)
		elseif direction == "Left" then
			rotation = CFrame.Angles(0, rotationSpeed, 0)
		end
		cameras[currentCameraIndex].CFrame = cameras[currentCameraIndex].CFrame * rotation
	end
end

local function startRotate(direction)
	local connection
	connection = RunService.RenderStepped:Connect(function()
		if UserInputService:IsMouseButtonPressed(Enum.UserInputType.MouseButton1) then
			rotateCamera(direction)
		else
			connection:Disconnect()
		end
	end)
end

Up.MouseButton1Down:Connect(function()
	startRotate("Up")
end)

Down.MouseButton1Down:Connect(function()
	startRotate("Down")
end)

Right.MouseButton1Down:Connect(function()
	startRotate("Right")
end)

Left.MouseButton1Down:Connect(function()
	startRotate("Left")
end)

button.MouseButton1Click:Connect(function()
	print("Clicked")
	if Viewing then
		Viewing = false
		NextCam.Visible = false
		PrevCam.Visible = false
		Camera.CameraType = Enum.CameraType.Custom
		Camera.FieldOfView = 70
		print("Camera changed to Custom")
	else
		Viewing = true
		NextCam.Visible = true
		PrevCam.Visible = true
		switchToCamera(currentCameraIndex)
		synchronizeCamera()
	end
end)

NextCam.MouseButton1Click:Connect(function()
	if Viewing then
		currentCameraIndex = currentCameraIndex % cameraCount + 1
		switchToCamera(currentCameraIndex)
	end
end)

You can use one of my previous solutions in this case.
This method uses spherical coordinates.
Just put the radius to zero (or omit it entirely).

Theta is left/right and phi is up/down
This code is an example so you can understand how it works
If you feel lazy (like me) you can also just copy it I don’t mind

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")

local currentCamera = workspace.CurrentCamera
currentCamera.CameraType = Enum.CameraType.Scriptable

local subjectPosition = Vector3.new(0, 10, 0)

local sensitivity = 0.5
local radius = 0 -- You can also omit radius from the function but for ease of use it's put to 0
local theta = 0
local phi = 90

function SphericalCoordinate(r: number, theta: number, phi: number)
	local Position = Vector3.new(
		r * math.sin(phi) * math.cos(theta),
		r * math.cos(phi),
		r * math.sin(phi) * math.sin(theta)
	)

	local Hat_r = Vector3.new(
		math.sin(phi) * math.cos(theta),
		math.cos(phi),
		math.sin(phi) * math.sin(theta)
	)

	local Hat_theta = Vector3.new(
		-math.sin(theta),
		0,
		math.cos(theta)
	)

	local Hat_phi = Vector3.new(
		math.cos(phi) * math.cos(theta),
		-math.sin(phi),
		math.cos(phi) * math.sin(theta)
	)

	return {
		Position = Position,
		UpVector = -Hat_phi,
		LeftVector = Hat_theta,
		FrontVector = -Hat_r,
		DownVector = Hat_phi,
		RightVector = -Hat_theta,
		BackVector = Hat_r
	}
end

UserInputService.InputBegan:Connect(function(input: InputObject, gameProcessedEvent: boolean)
	if gameProcessedEvent then return end
	if input.UserInputType ~= Enum.UserInputType.MouseButton2 then return end

	UserInputService.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
end)

UserInputService.InputEnded:Connect(function(input: InputObject, gameProcessedEvent: boolean)
	if gameProcessedEvent then return end
	if input.UserInputType ~= Enum.UserInputType.MouseButton2 then return end

	UserInputService.MouseBehavior = Enum.MouseBehavior.Default
end)

RunService.RenderStepped:Connect(function()
	for index, value in pairs(UserInputService:GetKeysPressed()) do
		if value.KeyCode == Enum.KeyCode.W then
			phi = (phi + 2 * sensitivity) % 360
		end
		if value.KeyCode == Enum.KeyCode.A then
			theta = (theta + -2 * sensitivity) % 360
		end
		if value.KeyCode == Enum.KeyCode.S then
			phi = (phi + -2 * sensitivity) % 360
		end
		if value.KeyCode == Enum.KeyCode.D then
			theta = (theta + 2 * sensitivity) % 360
		end
	end

	local sphericalCoordinate = SphericalCoordinate(
		radius,
		theta * math.pi / 180,
		phi * math.pi / 180
	)

	currentCamera.CFrame = CFrame.fromMatrix(
		sphericalCoordinate.Position + subjectPosition,
		sphericalCoordinate.RightVector, 
		sphericalCoordinate.UpVector, 
		sphericalCoordinate.BackVector
	)
end)

Remove Look Angle Limit

This is the reference local camera = workspace.CurrentCamera; local dir = Vector3.new(0,0,1); local xRot = 0; local yRot = 0; local inputService = game:GetService("UserInputService"); local lookAtPos = Vector3.zero; local sens = 0.5; local distance = 20; local range = 80; local scrollSens = 10; camera.CameraType = Enum.CameraType.Scriptable; game:GetService("RunService").RenderStepped:Connect(function(dt) local flipUp = false; -- Update desired x and y rotation yRot = (yRot + inputServic…

Removing MinZoomDistance?

You need to change the CameraMinZoomDistance from the player -- example in local script game:GetService("Players").LocalPlayer.CameraMinZoomDistance = 0 Even though, as the other guy mentioned, it is clamped to 0.5. And I don’t think the NearPlaneZ value can be edited. Additionally, spherical coordinates could be used to build your own camera system. Here is a more detailed version of one of my earlier postings! (to view my revision, you must slightly scroll down.) the reference for that …

How do I make a camera/movement camera system like Berserker

Here’s the explanation, pseudocode and source! Things to note: We aren’t doing any collision checks so the camera could go through obstacles The player and target should never be on the same X and Z positions which would possibly cause unexpected behavior I am not the best in explaining things so the source code is at the bottom if you don’t understand Explanation Regular camera system Do we need a custom camera system? In this case it would be nice to have a custom camera. A custom cam…

Hope this is what you were looking for.
If you have any questions feel free to ask me.
Hope you have a good day/night!

That is exactly what I was looking for, thank you for the help, I didn’t think it was that simple to do.
