BattleJong：服务器与客户端开发全解析

1. BattleJong 服务器开发

1.1 消息处理

当玩家清空棋盘或棋盘无有效移动时，会发送 “done” 消息，格式为 “done_ ”。以下是处理该消息的代码：

case "done":
  players[pid].stillPlaying = false;
  let playersDone: number = 0;
  for (const player in players) {
    if (players.hasOwnProperty(player)) {
      if (!players[player].stillPlaying) {
        playersDone++;
      }
    }
  }
  if (playersDone === 2) {
    let winningPID: string;
    const pids: string[] = Object.keys(players);
    if (players[pids[0]].score > players[pids[1]].score) {
      winningPID = pids[0];
    } else {
      winningPID = pids[1];
    }
    wsServer.clients.forEach(
      function each(inClient: WebSocket) : void {
        inClient.send(`gameOver_${winningPI
