*ADVANCED* How can I make a Free Camera Movement with in a 'Region3'?

Hi there! My problem is that I want to make a Free Camera Movement with in a Region3 Box, (like The Game Bloxburg).

I have got the code to move the camera, but I am unsure on how to actually control the Movement of the camera with-in that Box.

Here is what I have got so far: (Make sure to read after this script)

-- Creating the "Region3"
local point1 = game.Workspace.Point1
local point2 = game.Workspace.Point2
 
local region = Region3.new(point1.Position,point2.Position)

 -- To show the "Region3" in-game
local p = Instance.new("Part",workspace)
p.Anchored = true
p.CanCollide = false
p.Transparency = 0.8
p.Size = region.Size
p.CFrame = region.CFrame


--- Camera Movement
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local TweenService = game:GetService("TweenService")

local camera = workspace.CurrentCamera

camera.CameraType = Enum.CameraType.Scriptable

local x = 0 
local y = 12
local angle = Instance.new("CFrameValue")
local position = Vector3.new()

local nVec = {
	[Enum.KeyCode.A] = Vector3.new(-1, 0, 0),
	[Enum.KeyCode.D] = Vector3.new(1, 0, 0),
	[Enum.KeyCode.S] = Vector3.new(0, 0, 1),
	[Enum.KeyCode.W] = Vector3.new(0, 0, -1),
	[Enum.KeyCode.Q] = Vector3.new(0, -1, 0),
	[Enum.KeyCode.E] = Vector3.new(0, 1, 0)
}

local Vec = {}

local speed = 1

UISTable = {}

function UISTable.InputBegan(input)
	if nVec[input.KeyCode] then
		Vec[input.KeyCode] = nVec[input.KeyCode] 
	elseif input.UserInputType == Enum.UserInputType.MouseButton2 then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
	elseif input.KeyCode == Enum.KeyCode.LeftShift then
		speed = 0.1
	end
end

function UISTable.InputChanged(input)
	if input.UserInputType == Enum.UserInputType.MouseMovement then
		x = (x - math.rad(input.Delta.X))%(2*math.pi)
		y = math.clamp(y - math.rad(input.Delta.Y), math.rad(-89), math.rad(89))
		TweenService:Create(
			angle,
			TweenInfo.new(
				0.01,
				Enum.EasingStyle.Quad,
				Enum.EasingDirection.Out,
				0,
				false,
				0
			),
			{Value = CFrame.Angles(0, x, 0) * CFrame.Angles(y, 0, 0)}
		):Play()
	elseif input.UserInputType == Enum.UserInputType.MouseWheel then
		position = position + angle.Value * Vector3.new(0, 0, 5*input.Position.Z)
	end
end

function UISTable.InputEnded(input)
	if nVec[input.KeyCode] then
		Vec[input.KeyCode] = nil
	elseif input.UserInputType == Enum.UserInputType.MouseButton2 then
		UserInputService.MouseBehavior = Enum.MouseBehavior.Default
	elseif input.KeyCode == Enum.KeyCode.LeftShift then
		speed = 1
	end
end

for k, fn in pairs(UISTable) do
	UserInputService[k]:Connect(fn)
end

local function DefaultCam(dt)
	local move = Vector3.new()
	for _, v in pairs(Vec) do
		move = move + v
	end
	camera.CFrame = angle.Value + position
	position = position + angle.Value * (move * speed)
end

RunService:BindToRenderStep("DefaultCam", Enum.RenderPriority.Camera.Value, DefaultCam)

Does anyone know how I should integrate the Movement Control of the Camera with in that "Region3"?

Thank you, and have a Great Day! ????
