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.


Name Type Default Description

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

Handling InputBegan

The following example demonstrates one of many usage examples of handling user input from InputBegan depending on its type.

-- 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
UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if input.UserInputType == Enum.UserInputType.Keyboard then
		local keyPressed = input.KeyCode
		print("A key is being pushed down! Key:",input.KeyCode)
	elseif input.UserInputType == Enum.UserInputType.MouseButton1 then
		print("The left mouse button has been pressed down at",input.Position)
	elseif input.UserInputType == Enum.UserInputType.MouseButton2 then
		print("The right mouse button has been pressed down at",input.Position)
	elseif input.UserInputType == Enum.UserInputType.Touch then
		print("A touchscreen input has started at",input.Position)
	elseif input.UserInputType == Enum.UserInputType.Gamepad1 then
		print("A button is being pressed on a gamepad! Button:",input.KeyCode)

	if gameProcessed then
		print("\tThe game engine internally observed this input!")
		print("\tThe game engine did not internally observe this input!")
