Quiz

setMode(.paddle) · posX, primaryAction

Quiz is a trivia game: four answers A–D, Open Trivia DB questions (with caching), solo or two-player rounds. The phone is the remote; questions can display on TV via AirPlay.

How you play

1. Connect + calibrate.
2. Open Quiz — pick category, language, solo/duo in the flow.
3. Tilt to highlight A–D (posX → four slots).
4. Press the cap button to confirm the highlighted answer (like a remote OK).
5. Feedback shows correct/wrong; next question after a short pause.
6. Touch on the phone still submits immediately (tap any answer).

Category pick (before the round) uses Triki UI with preferButtonConfirm: true — tilt to focus, button to pick (no hold auto-select).

VeltoKit mapping

Setting	Value
MotionMode	.paddle
Selection	posX → TrikiSlotMath.slotIndex (4 answers)
Confirm	TrikiButtonConfirmGate on primaryAction (BLE edge + ~0.65 s cooldown)
Not used	Hold timer, velocity triggers, shotTriggered, sensors.click as confirm

Same mode as Pong, different game logic — good example of reusing .paddle for menus.

Integrate in your app

let motion = MotionSDK()
motion.setMode(.paddle)   // primaryAction = BLE button only in this mode
motion.connect()

var selected = 0
var confirmGate = TrikiButtonConfirmGate()  // sample app helper

func tick(dt: TimeInterval) {
  let input = motion.pollInput(deltaTime: dt)
  let slot = TrikiSlotMath.slotIndex(posX: input.posX, slots: 4)
  if slot != selected { selected = slot }

  if confirmGate.consume(input: input, deltaTime: dt) {
    submit(answer: selected)
  }
}

Copy TrikiButtonConfirmGate from app/UI/TrikiUI/ or implement your own edge + cooldown on primaryAction.

• Tune lateralDeadzone if the highlight jitters between A and B — Configuration.
• Questions require network on first load; see QuizCache for offline rounds.
