What's the API like?

Playroom Kit provides a simple API to set or get the state of the game room. The state is automatically synced between all players and screens.

import { getState, setState } from 'playroomkit'
// Set some game state, this will be synced to all players
setState("timeRemaining", 60);
// ...
// One some other device: Get the time remaining
const time = getState("timeRemaining");

Playroom also takes care of player and room management. You just need to call insertCoin() somewhere in your game to show the lobby UI.

import { insertCoin } from 'playroomkit'
// Show the lobby UI
await insertCoin();
// Handle players joining the game
onPlayerJoin((player) => {
  console.log(`${player.getProfile().name} joined the game`);

See the API Reference for more details.
