UserInputService
UserInputService is a service used to detect and capture the different types of input available on a user's device.
The primary purpose of this service is to allow for experiences to cooperate with multiple forms of available input, such as gamepads, touch screens, and keyboards. It allows a LocalScript to perform different actions depending on the device and, in turn, provide the best experience for the end user.
Some usages of this service include detecting user input when they interact with GUIs, tools, and other game instances. In order to detect user input, the service must look for a service event. For example, the service can detect events such as when the user touches the screen of a mobile device using UserInputService.TouchStarted, or connects a gamepad such as an Xbox controller to their device using UserInputService.GamepadConnected.
Since this service is client-side only, it will only work when used in a LocalScript or a ModuleScript required by a LocalScript. As UserInputService is client-side only, users in the game can only detect their own input - and not the input of others.
See also ContextActionService, a service which allows you to bind functions to multiple user inputs.
Code Samples

-- A sample function providing one usage of InputBegan
local function onInputBegan(input, _gameProcessed)
if input.UserInputType == Enum.UserInputType.MouseButton1 then
print("The left mouse button has been pressed!")
end

Properties
AccelerometerEnabled
This property describes whether the user's device has an accelerometer
An accelerometer is a component found in most mobile devices that measures acceleration (change in speed).
For example, the following code snippet demonstrates how to check if the user's device has an accelerometer.
If the device has an enabled accelerometer, you can get it's current acceleration by using the UserInputService:GetDeviceAcceleration() function or track when the device's acceleration changes by using the UserInputService.DeviceAccelerationChanged event.
As UserInputService is client-side only, this property can only be used in a LocalScript.

end)
endGamepadEnabled
This property describes whether the device being used by a user has an available gamepad. If gamepads are available, you can use UserInputService:GetConnectedGamepads() to retrieve a list of connected gamepads.
As UserInputService is client-side only, this property can only be used in a LocalScript.

local activeGamepad = getActiveGamepad()
print(activeGamepad)
endGyroscopeEnabled
This property describes whether the user's device has a gyroscope.
A gyroscope is a component found in most mobile devices that detects orientation and rotational speed.
If a user's device has a gyroscope, you can use incorporate it into your game using the UserInputService:GetDeviceRotation() function and UserInputService.DeviceRotationChanged event.
As UserInputService is client-side only, this property can only be used in a LocalScript.

end)
endKeyboardEnabled
This property describes whether the user's device has a keyboard available. This property is true when the user's device has an available keyboard, and false when it does not.
It can be used to determine whether the user has an available keyboard - which can be important if you want to check if you can use UserInputService:IsKeyDown() or UserInputService:GetKeysPressed() to check for keyboard input.
As UserInputService is client-side only, this property can only be used in a LocalScript.
Code Samples
local UserInputService = game:GetService("UserInputService")
if UserInputService.KeyboardEnabled then
print("The user's device has an available keyboard!")
else
print("The user's device does not have an available keyboard!")
endMouseBehavior
This property sets how the user's mouse behaves based on the Enum.MouseBehavior Enum. The default value is Enum.MouseBehavior.Default.
It can be set to three values:
- Default: The mouse moves freely around the user's screen.
- LockCenter: The mouse is locked, and cannot move from, the center of the user's screen.
- LockCurrentPosition: The mouse is locked, and cannot move from, it's current position on the user's screen at the time of locking.
The value of this property does not affect the sensitivity of events tracking mouse movement. For example, GetMouseDelta returns the same Vector2 screen position in pixels regardless of whether the mouse is locked or able to move freely around the user's screen. As a result, default scripts like those controlling the camera are not impacted by this property.
This property is overridden if a GuiButton with Modal enabled is GuiButton.Visible unless the player's right mouse button is down.
Note that, if the mouse is locked, UserInputService.InputChanged will still fire when the player moves the mouse and will pass in the Delta that the mouse attempted to move by. Additionally, if the player is kicked from the game, the mouse will be forcefully unlocked.
As UserInputService is client-side only, this property can only be used in a LocalScript.

endMouseDeltaSensitivity
This property determines the sensitivity of the user's Mouse.
The sensitivity determines the extent to which a movement of the physical mouse translates to a movement of the mouse in-game. This can be used to adjusted how sensitive events tracking mouse movement, like GetMouseDelta, are to mouse movement.
This property does not affect the movement of the mouse icon. Nor does it affect the Camera Sensitivity setting found in the Settings tab of the client's Settings menu, which also adjusts the sensitivity of events tracking mouse movement.
This property has a maximum value of 10 and a minimum value of 0. A lower value corresponds to lower sensitivity, and a higher value to higher sensitivity.
When sensitivity is 0, events that track the mouse's movement will still fire but all parameters and properties indicating the change in mouse position will return Vector2.new(), or Vector3.new() in the case of InputObject.Delta. For example, GetMouseDelta will always return (0, 0).

TouchEnabled
This property describes whether the user's current device has a touch screen available.
The property is used to determine if the user's device has a touch screen, and therefore if touch events will fire. If TouchEnabled is true, you can use UserInputService events such as UserInputService.TouchStarted and UserInputService.TouchEnded to track when a user starts and stops touching the screen of their device.
The code snippet below prints whether the user's device has a touch screen.

GamepadSupports
This function returns whether the given Enum.UserInputType gamepad supports a button corresponding with the given Enum.KeyCode. This function is used to determine valid gamepad inputs.
To determine which Enum.UserInputType gamepads are connected, use UserInputService:GetConnectedGamepads().
As UserInputService is client-side only, this function can only be used in a LocalScript.
See also:
Parameters
The Enum.UserInputType of the gamepad.
The Enum.KeyCode of the button in question.
Returns
Whether the given gamepad supports a button corresponding with the given Enum.KeyCode.
Code Samples
local UserInputService = game:GetService("UserInputService")
local ContextActionService = game:GetService("ContextActionService")
local controller = Enum.UserInputType.Gamepad1
local buttonX = Enum.KeyCode.ButtonX
local function isSupported(gamepad, keycode)
return UserInputService:GamepadSupports(gamepad, keycode)
end
local function action()
print("Action")
end
if isSupported(controller, buttonX) then
ContextActionService:BindAction("sample action", action, false, buttonX)
endGetConnectedGamepads
This function returns an array of Enum.UserInputType gamepads currently connected. If no gamepads are connected, this array will be empty. Additionally, it only returns UserInputType objects that are gamepads. For instance, this event will return a connected Gamepad1 object but not a Keyboard object.
For example, the following code snippet retrieves the connected gamepads and stores them in a variable named connectedGamepads.
To check if a specific gamepad is connected, use UserInputService:GetGamepadConnected().
As UserInputService is client-side only, this function can only be used in a LocalScript.
See also:
Returns
An array of UserInputTypes corresponding with the gamepads connected to the user's device.
Code Samples
local UserInputService = game:GetService("UserInputService")
local function getActiveGamepad()
local activeGamepad = nil
local connectedGamepads = UserInputService:GetConnectedGamepads()
if #connectedGamepads > 0 then
for _, gamepad in connectedGamepads do

end
return activeGamepad
end
if UserInputService.GamepadEnabled then
local activeGamepad = getActiveGamepad()
print(activeGamepad)
endGetDeviceAcceleration
The GetDeviceAcceleration function determines the current acceleration of the user's device. It returns an InputObject that describes the device's current acceleration.
In order for this to work, the user's device must have an enabled accelerometer. To check if a user's device has an enabled accelerometer, you can check the UserInputService.AccelerometerEnabled property.
If you want to track when the user's device's acceleration changes instead, you can use the UserInputService.DeviceAccelerationChanged event.
Since it only fires locally, it can only be used in a LocalScript.
Returns
Code Samples
local UserInputService = game:GetService("UserInputService")
local accelerometerEnabled = UserInputService.AccelerometerEnabled
if accelerometerEnabled then
local acceleration = UserInputService:GetDeviceAcceleration().Position
print(acceleration)
else
print("Cannot get device acceleration because device does not have an enabled accelerometer!")
endGetDeviceGravity
This function returns an InputObject describing the device's current gravity vector.
The gravity vector is determined by the device's orientation relative to the real-world force of gravity. For instance, if a device is perfectly upright (portrait), the gravity vector is Vector3.new(0, 0, -9.18). If the left side of the device is pointing down, the vector is Vector3.new(9.81, 0, 0). Finally, if the back of the device is pointing down, the vector is Vector3.new(0, -9.81, 0).
This function might be used to enable the user's device to impact or control gravity within the game or move in-game objects such as a ball.
Gravity is only tracked for players using a device with an enabled gyroscope - such as a mobile device.
To check if a user's device has an enabled gyroscope, check the value of UserInputService.GyroscopeEnabled. If the device has an enabled gyroscope, you can also use the UserInputService.DeviceGravityChanged event to track when force of gravity on the user's device changes.
As UserInputService is client-side only, this function can only be used in a LocalScript.
Returns
Code Samples
local UserInputService = game:GetService("UserInputService")
local bubble = script.Parent:WaitForChild("Bubble")
local camera = workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera.CFrame = CFrame.new(0, 20, 0) * CFrame.Angles(-math.pi / 2, 0, 0)
if UserInputService.GyroscopeEnabled then
-- Bind event to when gyroscope detects change
UserInputService.DeviceGravityChanged:Connect(function(accel)
-- Move the bubble in the world based on the gyroscope data
bubble.Position = Vector3.new(-8 * accel.Position.X, 1.8, -8 * accel.Position.Z)
end)
end
GetDeviceRotation
This function returns an InputObject and a CFrame describing the device's current rotation vector.
This is fired with an InputObject. The Position property of the input object is a Enum.InputType.Gyroscope that tracks the total rotation in each local device axis.
Device rotation can only be tracked on devices with a gyroscope.
As this function fires locally, it can only be used in a LocalScript.
Returns
A tuple containing two properties:
- The delta property describes the amount of rotation that last happened
- The CFrame is the device's current rotation relative to its default reference frame.
Code Samples
local UserInputService = game:GetService("UserInputService")
local gyroEnabled = UserInputService:GyroscopeEnabled()
if gyroEnabled then
local _inputObj, cframe = UserInputService:GetDeviceRotation()
print("CFrame: {", cframe, "}")
else
print("Cannot get device rotation because device does not have an enabled gyroscope!")
endGetFocusedTextBox
This function returns the TextBox the client is currently focused on. A TextBox can be manually selected by the user, or selection can be forced using the TextBox:CaptureFocus() function. If no TextBox is selected, this function will return nil.
As UserInputService is client-side only, this function can only be used in a LocalScript.

end
end
UserInputService.JumpRequest:Connect(jumpRequest)
humanoid.StateChanged:Connect(stateChanged)GetLastInputType
This function returns 'Enum.UserInputType` associated with the user's most recent input.
For example, if the user's previous input had been pressing the spacebar, the Enum.UserInputType returned would be 'Keyboard'.
The UserInputService.LastInputTypeChanged event can be used to track when the last Enum.UserInputType used by the user changes.
As UserInputService is client-side only, this function can only be used in a LocalScript.
Returns
The Enum.UserInputType associated with the user's most recent input.
Code Samples
local UserInputService = game:GetService("UserInputService")
local lastInput = UserInputService:GetLastInputType()
if lastInput == Enum.UserInputType.Keyboard then
print("Most recent input was via keyboard")
endGetMouseButtonsPressed
This function returns an array of InputObjects corresponding to the mouse buttons currently being pressed down.
Mouse buttons that are tracked by this function include:
| Name | Description |
|---|---|
| MouseButton1 | The left mouse button. |
| MouseButton2 | The right mouse button. |
| MouseButton3 | The middle mouse button. |
If the user is not pressing any mouse button down when the function is called, it will return an empty array.
As UserInputService is client-side only, this function can only be used in a LocalScript.
Returns
An array of InputObjects corresponding to the mouse buttons currently being currently held down.
Code Samples

m2Pressed = true
end
if m1Pressed and m2Pressed then
print("Both mouse buttons are pressed")
end
end
end)GetMouseDelta
This function returns the change, in pixels, of the position of the player's Mouse in the last rendered frame as a Vector2. This function only works if the mouse has been locked using the UserInputService.MouseBehavior property. If the mouse has not been locked, the returned Vector2 values will be zero.
The sensitivity of the mouse, determined in the client's settings and UserInputService.MouseDeltaSensitivity, will influence the result.
As UserInputService is client-side only, this function can only be used in a LocalScript.
Returns

An array of UserInputTypes that can be used for GUI navigation, in descending order of priority.
GetStringForKeyCode
GetStringForKeyCode returns a string representing a key the user should press in order to input a given Enum.KeyCode, keeping in mind their keyboard layout. For key codes that require some modifier to be held, this function returns the key to be pressed in addition to the modifier. See the examples below for further explanation.
When using Roblox with a non‑QWERTY keyboard layout, key codes are mapped to equivalent QWERTY positions. For example, pressing A on an AZERTY keyboard results in Enum.KeyCode.Q. This mapping can lead to mismatched information on experience UI elements. For example, "Press M to open the map" is inaccurate on an AZERTY keyboard; it would need to be "Press ? to open the map" which is in the same position as M on QWERTY. This function solves this issue by providing the actual key to be pressed while using non‑QWERTY keyboard layouts.
Examples on QWERTY Keyboard
| KeyCode | Return Value |
|---|---|
| Enum.KeyCode.Q | Q |
| Enum.KeyCode.W | W |
| Enum.KeyCode.Equals | = |
| Enum.KeyCode.At | 2 because @ is typed with Shift2 |
Examples on AZERTY Keyboard
| KeyCode | Return Value |
|---|---|
| Enum.KeyCode.Q | A |
| Enum.KeyCode.W | Z |
| Enum.KeyCode.Equals | = |
| Enum.KeyCode.At | É |
Gamepad Usage
GetStringForKeyCode() returns the string mapping for the Enum.KeyCode for the most recently connected gamepad. If the connected controller is not supported, the function returns the default string conversion for the requested key code.
The following example shows how you can map custom assets for ButtonA:
Gamepad Mappings
The directional pad key codes do not have any differences based on device. Enum.KeyCode.ButtonSelect has slightly different behavior in some cases. Use both PlayStation mappings to ensure users see the correct buttons.
| KeyCode | PlayStation Return Value | Xbox Return Value |
|---|---|---|
| Enum.KeyCode.ButtonA | ButtonCross | ButtonA |
| Enum.KeyCode.ButtonB | ButtonCircle | ButtonB |
| Enum.KeyCode.ButtonX | ButtonSquare | ButtonX |
| Enum.KeyCode.ButtonY | ButtonTriangle | ButtonY |
| Enum.KeyCode.ButtonL1 | ButtonL1 | ButtonLB |
| Enum.KeyCode.ButtonL2 | ButtonL2 | ButtonLT |
| Enum.KeyCode.ButtonL3 | ButtonL3 | ButtonLS |
| Enum.KeyCode.ButtonR1 | ButtonR1 | ButtonRB |
| Enum.KeyCode.ButtonR2 | ButtonR2 | ButtonRT |
| Enum.KeyCode.ButtonR3 | ButtonR3 | ButtonRS |
| Enum.KeyCode.ButtonStart | ButtonOptions | ButtonStart |
| Enum.KeyCode.ButtonSelect | ButtonTouchpad and ButtonShare | ButtonSelect |
System Images for KeyCodes
When using a Enum.KeyCode that may be better represented as an image, such as for an ImageLabel in a user interface, you can use the following legacy icons. However, it's recommended that you use GetImageForKeyCode() as a more modern, cross‑platform method to retrieve Xbox and PlayStation controller icons.

Parameters
Returns
GetSupportedGamepadKeyCodes
This function returns an array of KeyCodes that the gamepad associated with the given Enum.UserInputType supports.
This function can be used to determine which KeyCodes are supported and not supported by a connected gamepad. To determine if a specific KeyCode is supported, use UserInputService:GamepadSupports().
If called on a non existent, or non connected, gamepad, this function will return an empty array.
As UserInputService is client-side only, this function can only be used in a LocalScript.

endIsNavigationGamepad
This function returns true if the specified Enum.UserInputType gamepad is allowed to control Navigation and Selection GuiObjects.
If you want to set a navigation gamepad, you can use UserInputService:SetNavigationGamepad(). You can also use UserInputService:GetNavigationGamepads() to get a list of all navigation gamepads.
For example, the code below checks if the gamepad1 is as a navigation gamepad:
A list of all connected gamepads, regardless of navigation can be retrieved using`UserInput/GetConnectedGamepads.
Since UserInputService is client-side only, this function can only be used in a LocalScript.

Parameters
The Enum.UserInputType of the specified gamepad.
Returns
Whether the specified gamepad is a navigation gamepad.
RecenterUserHeadCFrame
This function recenters the CFrame of the VR headset to the current orientation of the headset worn by the user. This means that the headset's current orientation is set to CFrame.new().
Use this function to move the headset CFrame to the center of the play area if it seems to be at a weird offset.
This behaves identically to the VRService function, VRService:RecenterUserHeadCFrame().
Since UserInputService is client-side only, this function can only be used in a LocalScript.
Returns
Code Samples
local UserInputService = game:GetService("UserInputService")
UserInputService:RecenterUserHeadCFrame()SetNavigationGamepad
The SetNavigationGamepad function sets whether the specified Enum.UserInputType gamepad can move the GUI navigator. A gamepad that is allowed to move the GUI navigator is considered a navigation gamepad.
If the enabled argument is passed as true, the Gamepad can move the GUI navigator. If the argument is false, the Gamepad can not move the GUI navigator.
If you want to check if a specified Gamepad is a set to be a navigation gamepad, you can use the UserInputService:IsNavigationGamepad() function. You can also use the UserInputService:GetNavigationGamepads() to retrieve a list of all navigation gamepads.
Since UserInputService is client-side only, this function can only be used in a LocalScript.

Parameters
The Enum.UserInputType of the specified gamepad.
Whether the specified gamepad can move the GUI navigator.
Returns

UserInputService:SetNavigationGamepad(Enum.UserInputType.Gamepad1, true)Events
DeviceAccelerationChanged
The DeviceAccelerationChanged event fires when a user moves a device that has an accelerometer.
An accelerometer is a component found in most mobile devices that measures acceleration (change in speed).
To determine whether a user's device has an accelerometer enabled, seeUserInputService.AccelerometerEnabled.
This event can be used to track the movement of a device that has an accelerometer. A sample usage includes moving the player character when a mobile device accelerates.
Additionally, this event can be used along with UserInputService:GetDeviceAcceleration() to determine the current movement of a user's device if the device has an accelerometer.
This event only fires locally - which means that only the player whose device moves can use the event and it will only work in a LocalScript.
Parameters
An InputObject, with a UserInputType of 'Accelerometer', and Position that shows the force of gravity on each local device axis.
Code Samples
local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")
local SENSITIVITY = 0.2

humanoid:Move(Vector3.new(0, 0, -1))
end
task.wait(1)
ready = true
end
end
UserInputService.DeviceAccelerationChanged:Connect(changeAcceleration)DeviceGravityChanged
The UserInputService.DeviceGravityChanged event fires when the device's gravity Vector3 changes on a device that has an accelerometer.
A device's gravity vector represent the force of gravity on each of the device's X, Y, and Z axes. While gravity never changes, the force it exerts on each axis changes when the device rotates and changes orientation. The force value exerted on each axis is a unit vector ranging from -1 to 1.
An accelerometer is a component found in most mobile devices that measures acceleration (change in speed).
This event can be used to determine the real-world direction of the force of gravity on a user's device. This even can then be used to simulate the force of gravity on a user's device within the game, such as on in-game objects (see example below).
To check if a user's device has an enabled accelerometer, see UserInputService.AccelerometerEnabled. If the device has an enabled accelerometer, you can use the UserInputService:GetDeviceGravity() function to get the current force of gravity on the user's device.
Parameters
An InputObject, with a InputObject.Position property that shows the force of gravity on each local device axis. This position can be used as a direction to determine the direction of gravity relative to the device.

end)
endDeviceRotationChanged
The DeviceRotationChanged event fires when a user rotates a device that has a gyroscope.
A gyroscope is a component found in most mobile devices that detects orientation and rotational speed.
The event is useful when tracking the orientation of the device and how changes as the user rotates their device. To determine the current device rotation, you can use the UserInputService:GetDeviceRotation() function.
To check if a user's device has an enabled gyroscope, and that this event will fire, see UserInputService.GyroscopeEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
Parameters
An InputObject providing info about the device's rotation. InputObject.Position represents the new rotation a Vector3 positional value and InputObject.Delta represents the change in rotation in a Vector3 positional value.

GamepadConnected
The GamepadConnected event fires when a gamepad is connected to the client.
Since a Roblox game supports multiple controllers, this event is useful when paired with the UserInputService.GamepadDisconnected event to track which controllers/gamepads are active. You can also use UserInputService:GetConnectedGamepads() to find the correct gamepad to use.
The following example demonstrates a usage example of a tracking when a gamepad is connected to the client.
local UserInputService = game:GetService("UserInputService")
local function GamepadConnected(gamepad)
print("Player has plugged controller: " .. tostring(gamepad))
end)
UserInputService.GamepadConnected:Connect(GamepadConnected)
If you want to see which devices are connected, you can use the UserInputService:GetConnectedGamepads() function.
As this event fires locally, it can only be used in a LocalScript.
See also:
Parameters
The Enum.UserInputType of the connected gamepad.
GamepadDisconnected
The GamepadDisconnected event fires when a gamepad is disconnected.
Since a Roblox game supports multiple controllers, this event is useful when paired with the UserInputService.GamepadConnected event to track which controllers/gamepads are active. You can also use UserInputService:GetConnectedGamepads() to find the correct gamepad to use.
The following example demonstrates a usage example of a tracking when a gamepad is disconnected from the client.
local UserInputService = game:GetService("UserInputService")
local function GamepadDisconnected(gamepad)
print("Player has unplugged controller: " .. tostring(gamepad))
end)
UserInputService.GamepadDisconnected:Connect(GamepadDisconnected)
As this event fires locally, it can only be used in a LocalScript.
See also:
Parameters
TheEnum.UserInputType of the disconnected gamepad.
InputBegan
The InputBegan event fires when a user begins interacting via a Human-Computer Interface device (mouse button down, touch begin, keyboard button down, etc.).
It can be used to track the beginning of user interaction, such as when a user first interacts with a GUI element, a gamepad, etc. It does not capture mouse wheel movements.
This event can be used along with UserInputService.InputChanged and UserInputService.InputEnded to track when user input begins, changes, and ends.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.
Parameters
An InputObject instance, which contains information about the user's input.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.
Code Samples
-- In order to use the InputBegan event, the UserInputService service must be used
local UserInputService = game:GetService("UserInputService")
-- A sample function providing multiple usage cases for various types of user input

print("The game engine did not internally observe this input!")
end
end)InputChanged
The InputChanged event fires when a user changes how they're interacting via a Human-Computer Interface device (mouse button down, touch begin, keyboard button down, etc).
To ignore events that are automatically handled by Roblox, like scrolling in a ScrollingFrame, check the gameProcessedEvent argument is false. This event can be used along with UserInputService.InputBegan and UserInputService.InputEnded to track when user input begins, changes, and ends.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.
Parameters
An InputObject instance, which contains information about the user's input.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.
Code Samples
-- In order to use the InputChanged event, the UserInputService service must be used
local UserInputService = game:GetService("UserInputService")
-- Prints the current input position and the change (delta) in position
local function printMovement(input)
print("Position:", input.Position)
print("Movement Delta:", input.Delta)
end
-- A sample function providing multiple usage cases for various types of user input
local function InputChanged(input, _gameProcessed)
if input.UserInputType == Enum.UserInputType.MouseMovement then
print("The mouse has been moved!")
printMovement(input)
elseif input.UserInputType == Enum.UserInputType.MouseWheel then
print("The mouse wheel has been scrolled!")
print("Wheel Movement:", input.Position.Z)
elseif input.UserInputType == Enum.UserInputType.Gamepad1 then

elseif input.UserInputType == Enum.UserInputType.Accelerometer then
print("The acceleration of the user's mobile device has been changed!")
printMovement(input)
end
end
UserInputService.InputChanged:Connect(InputChanged)InputEnded
The InputEnded event fires when a user stops interacting via a Human-Computer Interface device (mouse button down, touch begin, keyboard button down, etc). This is useful when tracking when a user releases a keyboard key, mouse button, touchscreen input, etc.
This event can be used along with UserInputService.InputBegan and UserInputService.InputChanged to track when user input begins, changes, and ends.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.
Parameters
An InputObject instance, which contains information about the user input.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.
Code Samples
-- In order to use the InputChanged event, the UserInputService service must be used
local UserInputService = game:GetService("UserInputService")
-- A sample function providing multiple usage cases for various types of user input
UserInputService.InputEnded:Connect(function(input, gameProcessed)
if input.UserInputType == Enum.UserInputType.Keyboard then
print("A key has been released! Key:", input.KeyCode)
elseif input.UserInputType == Enum.UserInputType.MouseButton1 then
print("The left mouse button has been released at", input.Position)
elseif input.UserInputType == Enum.UserInputType.MouseButton2 then
print("The right mouse button has been released at", input.Position)
elseif input.UserInputType == Enum.UserInputType.Touch then
print("A touchscreen input has been released at", input.Position)
elseif input.UserInputType == Enum.UserInputType.Gamepad1 then
print("A button has been released on a gamepad! Button:", input.KeyCode)
end
if gameProcessed then
print("The game engine internally observed this input!")
else
print("The game engine did not internally observe this input!")
end
end)JumpRequest
The UserInputService JumpRequest event fires when there is a jump request from the client, for example when the client presses the spacebar or jump button on mobile.
This event fires whenever the user tries to make their Player.Character jump. Default behavior responds to a jump request by setting the player's Humanoid.Jump property to true, which makes the player's character jump.
The event can be used to track every time a player wants to jump. Instead of using it to make a player jump, this should be used to change default jump behavior - such as disabling jumping.
For example, the code below prints "Jump" every time the player sends a jump request.
local UserInputService = game:GetService("UserInputService")
function onJumpRequest()
print("Jump!")
end
UserInputService.JumpRequest:Connect(onJumpRequest)
Since this event fires multiple times for a single jump request, using a debounce is suggested.
If you would like to connect keys or buttons to other actions, consider using events such as UserInputService:GetKeysPressed() and UserInputService.InputBegan or the ContextActionService.
As this event only fires locally, it can only be used in a LocalScript.
Code Samples
local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")
local player = Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
-- Fires when the user tries to jump
local function jump()
humanoid:SetStateEnabled(Enum.HumanoidStateType.Jumping, false)
end
UserInputService.JumpRequest:Connect(jump)LastInputTypeChanged
The UserInputService.LastInputTypeChanged event fires whenever the client changes how they are interacting via a Human-Computer Interface device. (i.e. from MouseMovement to MouseWheel or from Thumbstick1 to Thumbstick2).
To get the value of the last input type, regardless of whether it has changed, you can use the UserInputService:GetLastInputType() function.
As this event only fires locally, it can only be used in a LocalScript.
Parameters
A Enum.UserInputType indicating the last input type.
Code Samples
local UserInputService = game:GetService("UserInputService")
local mouseInput = {
Enum.UserInputType.MouseButton1,
Enum.UserInputType.MouseButton2,
Enum.UserInputType.MouseButton3,
Enum.UserInputType.MouseMovement,
Enum.UserInputType.MouseWheel,
}
local keyboard = Enum.UserInputType.Keyboard
local function toggleMouse(lastInputType)
if lastInputType == keyboard then
UserInputService.MouseIconEnabled = false
return
end
for _, mouse in pairs(mouseInput) do
if lastInputType == mouse then
UserInputService.MouseIconEnabled = true
return
end
end
end
UserInputService.LastInputTypeChanged:Connect(toggleMouse)PointerAction
PointerAction fires when the user performs a specific pointer action. In particular, scrolling the mouse wheel.
Parameters
TextBoxFocusReleased
The TextBoxFocusReleased event fires when a client loses focus on a TextBox - typically when a client stops text entry into a TextBox by pressing return or clicking/touching elsewhere on the screen.
For example, the code below prints the name of the TextBox losing focus when the event fires.
local UserInputService = game:GetService("UserInputService")
function TextBoxFocusReleased(textbox)
print(textbox.Name)
end
UserInputService.TextBoxFocusReleased:Connect(TextBoxFocusReleased)
It can be used alongside UserInputService.TextBoxFocused to track when a TextBox gains and loses focus.
As this event only fires locally, it can only be used in a LocalScript.

Parameters
Code Samples
local UserInputService = game:GetService("UserInputService")
UserInputService.TextBoxFocusReleased:Connect(function(textbox)
print("The name of the released focus TextBox is " .. textbox.Name)
end)TextBoxFocused
The TextBoxFocused event fires when a gains focus on a TextBox - typically when a client clicks/taps on a text box to begin inputting text. This also fires if a text box focus is focused using TextBox:CaptureFocus().
For example, the code below prints the name of the TextBox focused when the event fires.
local UserInputService = game:GetService("UserInputService")
function TextBoxFocused(textbox)
print(textbox.Name)
end)
UserInputService.TextBoxFocused:Connect(TextBoxFocused)
It can be used alongside UserInputService.FocusReleased to track when a text box gains and loses focus.
As this event only fires locally, it can only be used in a LocalScript.

Parameters
Code Samples
local UserInputService = game:GetService("UserInputService")
local function textBoxFocused(textBox)
textBox.BackgroundTransparency = 0
end
local function textBoxFocusReleased(textBox)
textBox.BackgroundTransparency = 0.7
end
UserInputService.TextBoxFocused:Connect(textBoxFocused)
UserInputService.TextBoxFocusReleased:Connect(textBoxFocusReleased)TouchEnded
The TouchEnded event fires when a user released their finger from the screen of a TouchEnabled device, ending touch input with the device.
This event can be used to determine when a user stops touching the screen of their device. It can be paired with UserInputService.TouchStarted to determine when a user starts and stops touching the screen.
For example, the code below prints the screen position where the user stops touching the screen.
local UserInputService = game:GetService("UserInputService")
function TouchEnded(touch, gameProcessedEvent)
print("Touch ended at " .. tostring(touch.Position))
end
UserInputService.TouchEnded:Connect(TouchEnded)
The touch input object is the same input object throughout the lifetime of the touch. So comparing InputObjects when they are touch objects is valid to determine if it is the same finger.
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.

UserInputService.TouchEnded:Connect(TouchEnd)
endTouchLongPress
Fired when a user holds at least one finger for a short amount of time on the same screen position of a TouchEnabled device.
This event can be used to determine when a user holds their finger down on an in-game GuiObject or element.
The example below prints the state of the long press when the user holds at least one finger for a short amount of time on the same screen position. Possible states include: Begin, Change, End, Cancel, and None.
local UserInputService = game:GetService("UserInputService")
function TouchLongPress(TouchPositions, state, gameProcessedEvent)
print("Long press event fired. State of press: " .. tostring(state))
end

endTouchPan
The TouchPan event fires when a user drags at least one finger on a TouchEnabled device.
This event can be used to determine when a user pans their finger along screen of a TouchEnabled device - such as to rotate the Camera in a custom camera script.
The snippet below prints "Speed of touch drag" followed by the velocity of the user's touch when the user drags their finger on the screen.
local UserInputService = game:GetService("UserInputService")
UserInputService.TouchPan:Connect(function(touchPositions, totalTranslation, velocity, state, gameProcessedEvent)
print("Speed of touch drag: " .. tostring(velocity))
end)

endTouchRotate
The TouchRotate event fires when a user rotates two fingers on a TouchEnabled device.
For example, the following code prints how much the camera has rotated since the beginning of the touch rotation.
local UserInputService = game:GetService("UserInputService")
UserInputService.TouchRotate:Connect(function(touchPositions, rotation, velocity, state, gameProcessedEvent)
print("Camera has rotated " .. tostring(rotation) .. " degrees!")
end)
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.
The core scripts that control the user's camera on a mobile device use code that functions similarly to this event. Best practice for this event is to use it when creating a mobile camera system to override the default core scripts.

Parameters
An array of Vector2s, indicating the positions of the fingers involved in the gesture.
The number of degree the gesture has rotated since the start of the gesture.
The change in rotation (in degrees) divided by the duration of the change (in seconds).
The Enum.UserInputState of the gesture.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.

endTouchStarted
The TouchStarted event fires when a user places their finger on a TouchEnabled device, beginning touch input with the device.
This event can be used to determine when a user starts touching the screen of their device. It can be paired with UserInputService.TouchEnded to determine when a user starts and stops touching the screen.
The touch input object is the same input object throughout the lifetime of the touch. So comparing InputObjects when they are touch objects is valid to determine if it is the same finger.
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.

Parameters
An InputObject instance, which contains information about the user's input.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.

The TouchSwipe event fires when a user swipes their fingers on a TouchEnabled device.
This event can be used to determine when a user swipes their fingers on the screen of their device and the direction that the user swiped.
For more precise tracking of touch input movement, use using UserInputService.TouchMoved
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.

end
UserInputService.TouchSwipe:Connect(TouchSwipe)TouchTap
The TouchTap event fires when the user touches/taps their finger on the screen on a TouchEnabled device.
This event will fire regardless of whether the user touches/taps the game world or a GuiObject element. If you are looking for an event that only fires when the user touches/taps the game world, use UserInputService.TouchTapInWorld.
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As this event only fires locally, it can only be used in a LocalScript.
Parameters
An array of Vector2 objects, indicating the position of the fingers involved in the tap gesture.
Indicates whether the game engine internally observed this input and acted on it. Generally this refers to UI processing, so if a button was touched or clicked from this input, gameProcessedEvent would be true. This is also true for input events connected via ContextActionService.

endTouchTapInWorld
The TouchTapInWorld event fires when the user touches/taps their finger on the screen on a TouchEnabled device. It is fired when the user taps in the game world.
This event can be used to determine when a user taps the screen and does not tap a GuiObject element. If the user taps a GUI element, UserInputService.TouchTap will fire instead of TouchTapInWorld.
To check if a user's device is TouchEnabled, and that touch events will fire, see UserInputService.TouchEnabled.
This event only fires when the Roblox client window is in focus. For example, inputs will not be captured when the window is minimized.
As it only fires locally, it can only be used in a LocalScript.

end
end
UserInputService.TouchTapInWorld:Connect(createPart)WindowFocusReleased
The UserInputService WindowFocusReleased event fires when the window of the Roblox client loses focus - typically when the Roblox client is minimized by the user.
For example, the code below prints "Window focus released" whenever the Roblox client loses focus.
local UserInputService = game:GetService("UserInputService")
UserInputService.WindowFocusReleased:Connect(function()
print("Window focus released")
end)
This event can be used alongside UserInputService.WindowFocused to track whether the Roblox client is actively focused on a user's screen.
Since it only fires locally, it can only be used in a LocalScript.

For example, the code below prints "Window focused" whenever the Roblox client gains focus.
local UserInputService = game:GetService("UserInputService")
UserInputService.WindowFocused:Connect(function()
