Load for keyboard, mouse, gamepad, touch, motion, or cross-platform action binding. Client-side only. For simulation-affecting input in a Server Authority project, use the Input Action System rather than traditional input events.
Core events (UserInputService): InputBegan, InputChanged, InputEnded fire as (input: InputObject, gameProcessedEvent: boolean). InputBegan does NOT fire for mouse wheel. Events only fire while the client window is focused.
Prefer ContextActionService over InputBegan for gameplay โ free conflict resolution (chat won't steal H) and free mobile buttons:
local CAS = game:GetService("ContextActionService")
local function onAction(name, state, _input)
if name == "Jump" and state == Enum.UserInputState.Begin then
humanoid.Jump = true
end
end
CAS:BindAction("Jump", onAction, true,
Enum.KeyCode.Space, Enum.KeyCode.ButtonA)
BindAction(name, handler, createTouchButton, ...inputTypes). Handler returns ContextActionResult.Sink to consume, .Pass to fall through.
Server Authority: use InputAction/InputContext for inputs that affect the core simulation, store the input state where the synchronized simulation can read it, and process it through RunService:BindToSimulation(). ContextActionService remains appropriate for UI-only or classic-project actions.
Gamepad UI focus: separate gameplay bindings from menu selection. Set GuiService.SelectedObject, mark controls Selectable, and test nested/modal navigation.
Gamepad: use GetConnectedGamepads() and listen to connection changes.
Touch: use high-level gesture events or raw TouchStarted/TouchMoved/TouchEnded when tracking fingers.
Pitfalls:
gameProcessedEvent=true in InputBegan โ UI consumed it. Filter for gameplay.BindAction is stack-based: most-recent wins. Use BindActionAtPriority.JumpRequest fires multiple times per jump โ debounce.InputChanged.Full event tables and polling methods: references/full.md.
