📘 UserInputService Notes (Roblox Studio)

🔹 Purpose

• Detects keyboard, mouse, touch, and gamepad input.
• Good for custom controls, hotkeys, mobile gestures, etc.

🔹 Getting the Service

local UserInputService = game:GetService("UserInputService")

🔹 Main Events

1. InputBegan → fires when input starts (key pressed, mouse clicked, touch began).

   UserInputService.InputBegan:Connect(function(input, gameProcessed)
       if gameProcessed then return end -- ignore if chat/menu handled it
       if input.KeyCode == Enum.KeyCode.Space then
           print("Spacebar pressed")
       end
   end)
   
   

2. InputEnded → fires when input stops (key released, mouse button lifted).

   UserInputService.InputEnded:Connect(function(input)
       if input.KeyCode == Enum.KeyCode.Space then
           print("Spacebar released")
       end
   end)
   
   

3. InputChanged → fires when input changes (mouse moves, joystick tilts, touch moves).

   UserInputService.InputChanged:Connect(function(input)
       if input.UserInputType == Enum.UserInputType.MouseMovement then
           print("Mouse moved:", input.Position)
       end
   end)
   
   

🔹 Checking Input

• Keyboard: input.KeyCode
• Mouse: input.UserInputType (e.g., MouseButton1, MouseMovement)
• Touch: UserInputType.Touch
• Gamepad: UserInputType.Gamepad1, buttons like Enum.KeyCode.ButtonA
