How do I use mouse.Hit with a Locked Mouse?

Help and Feedback Scripting Support
#1

I am piloting a spaceship and my mouse is locked, but I want to rotate the ship using bodyGyro towards the mouse location (calculated using mouse.Delta, which gives mouse movement). How do I go that?

#2

Mouse.Hit should still work regardless of if your mouse is locked or not.

#3

I want to get the mouses position so I can rotate to where they are pointing to, but it won’t work with a locked mouse since it’ll keep returning the same value (where the mouse is locked).

#4

In that case, yes, you would use delta. I do remember a document on this:

Here’s what the docs has as the example:

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

local camera = workspace.CurrentCamera

local player = Players.LocalPlayer
local character = player.CharacterAdded:Wait()
local torso = character:WaitForChild("HumanoidRootPart")
local playerPosition = torso.Position

local default_CameraPosition = torso.Position
local default_CameraRotation = Vector2.new(0, math.rad(-60))
local default_CameraZoom = 15

local cameraPosition = default_CameraPosition
local cameraRotation = default_CameraRotation
local cameraZoom = default_CameraZoom

local cameraZoomBounds = nil -- {10,200}
local cameraRotateSpeed = 10
local cameraMouseRotateSpeed = 0.25
local cameraTouchRotateSpeed = 10

local function SetCameraMode()
	camera.CameraType = "Scriptable"
	camera.FieldOfView = 80
	camera.CameraSubject = nil
end

local function UpdateCamera()
	SetCameraMode()
	local cameraRotationCFrame = CFrame.Angles(0, cameraRotation.X, 0) * CFrame.Angles(cameraRotation.Y, 0, 0)
	camera.CFrame = cameraRotationCFrame + cameraPosition + cameraRotationCFrame * Vector3.new(0, 0, cameraZoom)
	camera.Focus = camera.CFrame - Vector3.new(0, camera.CFrame.p.Y, 0)
end

local lastTouchTranslation = nil
local function TouchMove(_touchPositions, totalTranslation, _velocity, state)
	if state == Enum.UserInputState.Change or state == Enum.UserInputState.End then
		local difference = totalTranslation - lastTouchTranslation
		cameraPosition = cameraPosition + Vector3.new(difference.X, 0, difference.Y)
		UpdateCamera()
	end
	lastTouchTranslation = totalTranslation
end

local lastTouchRotation = nil
local function TouchRotate(_touchPositions, rotation, _velocity, state)
	if state == Enum.UserInputState.Change or state == Enum.UserInputState.End then

			+ Vector2.new(-difference, 0) * math.rad(cameraTouchRotateSpeed * cameraRotateSpeed)
		UpdateCamera()
	end
	lastTouchRotation = rotation
end

local lastTouchScale = nil
local function TouchZoom(_touchPositions, scale, _velocity, state)
	if state == Enum.UserInputState.Change or state == Enum.UserInputState.End then
		local difference = scale - lastTouchScale
		cameraZoom = cameraZoom * (1 + difference)
		if cameraZoomBounds ~= nil then
			cameraZoom = math.min(math.max(cameraZoom, cameraZoomBounds[1]), cameraZoomBounds[2])
		else
			cameraZoom = math.max(cameraZoom, 0)
		end
		UpdateCamera()
	end
	lastTouchScale = scale
end

local function Input(inputObject)
	if inputObject.UserInputType == Enum.UserInputType.Keyboard then
		if inputObject.UserInputState == Enum.UserInputState.Begin then
			-- (I) Zoom In
			if inputObject.KeyCode == Enum.KeyCode.I then
				cameraZoom = cameraZoom - 15
			elseif inputObject.KeyCode == Enum.KeyCode.O then
				cameraZoom = cameraZoom + 15
			end

			-- (O) Zoom Out
			if cameraZoomBounds ~= nil then
				cameraZoom = math.min(math.max(cameraZoom, cameraZoomBounds[1]), cameraZoomBounds[2])
			else
				cameraZoom = math.max(cameraZoom, 0)
			end

			UpdateCamera()
		end
	end

	local pressed = UserInputService:IsMouseButtonPressed(Enum.UserInputType.MouseButton1)
	if pressed then
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
		local rotation = UserInputService:GetMouseDelta()
		cameraRotation = cameraRotation + rotation * math.rad(cameraMouseRotateSpeed)
	else
		UserInputService.MouseBehavior = Enum.MouseBehavior.Default
	end
end

local function PlayerChanged()
	local movement = torso.Position - playerPosition
	cameraPosition = cameraPosition + movement
	playerPosition = torso.Position

	UpdateCamera()
end

-- Determine whether the user is on a mobile device
if UserInputService.TouchEnabled then
	-- The user is on a mobile device, use Touch events
	UserInputService.TouchPan:Connect(TouchMove)
	UserInputService.TouchRotate:Connect(TouchRotate)
	UserInputService.TouchPinch:Connect(TouchZoom)
else
	-- The user is not on a mobile device use Input events
	UserInputService.InputBegan:Connect(Input)
	UserInputService.InputChanged:Connect(Input)
	UserInputService.InputEnded:Connect(Input)

	-- Camera controlled by player movement
	task.wait(2)
	RunService:BindToRenderStep("PlayerChanged", Enum.RenderPriority.Camera.Value - 1, PlayerChanged)
