Getting Started With UserInputService

To begin using UserInputService in your Roblox project, you first need to get a reference to the service through Roblox’s API: ```lua local UserInputService = game:GetService("UserInputService") ``` Once you have this, you can connect functions to various events that fire when players interact with their input devices.

Listening to Input Events

UserInputService exposes several important events, including:

InputBegan: Fired when an input (like a key press or mouse button down) starts.
InputEnded: Fired when an input ends (like releasing a key or mouse button).
InputChanged: Fired when an input changes value, useful for detecting mouse movement or joystick tilts.
TouchEnabled: Property that checks if the device supports touch input.

Here's a simple example of detecting when the player presses the "W" key: ```lua UserInputService.InputBegan:Connect(function(input, gameProcessedEvent) if gameProcessedEvent then return end -- Ignore input if the game already processed it if input.KeyCode == Enum.KeyCode.W then print("Player pressed W!") end end) ```

Handling GameProcessedInput

One important parameter in many UserInputService events is `gameProcessedEvent`. This boolean indicates whether Roblox’s default controls (like chat or player movement) have already handled the input. Checking this helps prevent conflicts, ensuring your custom input logic only runs when appropriate.
