Guesses, votes and teams

Players answer a StreamArena game in one of three ways: a guess (free text), a vote (a number) or a team word. A game declares which ones it uses in inputs, and the first one sets the "how to play" line on stream.

Input	Viewers type	Use it for
guess	Free text, like dune	Naming a film, a photo, an emoji puzzle
vote	A number, like 1 or 2	Two or three options, one right answer
team	A team word, like !cats	Two or more sides racing each other

Guesses

chat.expect(answers) is the one-line version: loose matching, faster answers score more, the first right answer gets a bonus, and each player scores once.

chat.expect(item.title, { points: 1000, min: 200, first: 250 })

For your own rules, use chat.onAnswer() and mark winners with player.correct(points):

chat.onAnswer((player, text, { at, platform, secret }) => {
  if (text.matches(item.answers)) player.correct(1000 - at * 40)
})

Votes

chat.vote(options) returns a poll with live bars. Players type 1, 2 or 3, or tap on their phone, and the last vote counts. Call close() before poll.score(), so late YouTube votes still count.

higher-or-lower.js

async round({ item, show, chat, phone, house, timer, close, reveal }) {
  const opts = [item.a, item.b]
  const poll = chat.vote(opts).render(show.html('<div class="tally"></div>'))
  phone.prompt({ text: item.q, input: 'vote', options: opts })
  house.vote(item.answer)

  await timer(20)
  await close()
  poll.score(item.answer, { points: 500, fast: 300 })
  await reveal(opts[item.answer])
}

Teams

chat.teams() takes the team words, and onPull() fires on every counted message. Each player counts at most once every half second.

tug-of-war.js

async round({ chat, timer, reveal }) {
  const teams = chat.teams([
    { id: 'cats', words: ['cats', '!cats'] },
    { id: 'dogs', words: ['dogs', '!dogs'] },
  ])
  teams.onPull((team) => moveRope(team.id))
  await timer(45)
  const c = teams.counts()
  await reveal(c.cats > c.dogs ? 'Cats win' : 'Dogs win')
}

Phones

phone.prompt() sets what phone players see this round. It defaults to the game's first input.

phone.prompt({ text: 'Which is older?', input: 'vote', options: ['Statue of Liberty', 'Eiffel Tower'] })
