Draw your own board - Smash&Clash

Use the seat sync to show a game your own way: a chat bot that posts the board, a custom client, a stream overlay. It’s what the website’s own match uses for a person’s seat. It returns:

Your seat’s state: your hand and the board by card id, the special tiles, and only counts for the other hand and the draw pile.
Every move since since: each with its public events and the state after it.

let since = 0;
for (;;) {
  const s = await game.sync({ since, wait: 20 });
  for (const m of s.moves) draw(m.events, m.state);
  since = s.moveCount;
  if (s.status === 'finished' || s.status === 'abandoned') break;
}

The state

{
  "ruleset": "mutators",
  "board": [[{ "cardId": 44, "owner": "B", "frozen": false }, null, null, null, null], [ … ], [ … ]],
  "hand": [28, 9, 46, 37, 30],
  "opponentHand": 5,
  "deck": 40,
  "current": "A",
  "gameOver": false,
  "winner": null,
  "turn": 2,
  "operatorTiles": [{ "cell": { "r": 2, "c": 4 }, "piece": "BISHOP" }],
  "powerTiles": [{ "cell": { "r": 1, "c": 3 }, "color": "purple", "boost": 1 }],
  "pendingHop": null
}

board[r][c]: r 0–2 is rows 1–3, and c 0–4 is columns A–E.
Card ids name cards in the card list, which gives values, colours and images.
A card’s sides are read from its owner’s side; see move names.

The moves

Each entry in moves is { index, seat, name, move, events, state }. The events describe what happened, in order:

Event	Fields
`cardPlaced`	`player`, `cardId`, `cell`
`cardsCaptured`	`cells`, `newOwner`
`effectPlayed`	`player`, `effect`, `cardId`
`boulderRemoved`	`cells`, `cardIds`, `target`
`boardFlipped`, `handsSwapped`	none
`cardFrozen`	`cell`
`cardRecruited`	`from`, `to`, `cardId`, `newOwner`
`cardsDrawn`	`player`, `count`
`turnStarted`	`player`
`hopAvailable` / `cardHopped` / `hopDeclined`	the chess-tile hop
`powerTilesAssigned` / `powerBoostApplied`	Mutators power tiles
`cardOverrun`	`cell`, `removedCardId`, `newCardId`
`gameOver`	`winner`, `scores`

Nothing in a sync shows a card the seat couldn’t see at the table. A draw is a count, and a swap carries no ids. When the game is over, reveal carries its seed. See fair play.
