Question

我正在用jQuery开发一个基于文本的冒险游戏，我想实现一个战斗功能，如果房间中有敌人，您可以说“攻击敌人”，然后您和敌人进行贸易攻击，直到有人死。如果您有武器，那么您的攻击就会被抛光

我试图编写这个战斗功能

    function fight(en) {
  if(rooms[currentRoom].enemys[en]!== undefined) {
    $('#game-text').append("<p>" + rooms[currentRoom].enemys[en] + "</p>");
    if(stats[user].hp > 0 || stats[en].hp > 0) {
      //user attacks
      stats[en].hp -= stats.user.attack;
      alert(stats.en.hp);
    }
    else {
      $('#game-text').append("<p>You can not fight here</p>");
    }
  }
}

现在，当调用该函数时，它将从此行$('#game-text').append("<p>" + rooms[currentRoom].enemys[en] + "</p>");链接到敌人的消息但是，它不会警告健康。

这似乎是相关的代码。

 switch(command) {
    case "go":
        var dir = input.split(" ")[1];
        changeRoom(dir);
        break;
    case "help":
        showHelp();
        break;
    case "inventory":
        showInventory();
        break;
    case "take":
      var item = input.split(" ")[1];
      takeItem(item);
      break;
    case "fight":
      var en = input.split(" ")[1];
      fight(en);
      break;
    default:
        alert("invalid move!");
  }

function fight(en) {
  if(rooms[currentRoom].enemys[en]!== undefined) {
    $('#game-text').append("<p>" + rooms[currentRoom].enemys[en] + "</p>");
    if(stats[user].hp > 0 || stats[en].hp > 0) {
      //user attacks
      stats[en].hp -= stats.user.attack;
      alert(stats.en.hp);
    }
    else {
      $('#game-text').append("<p>You can not fight here</p>");
    }
  }
}

var stats= {
  "user" : {
    "hp" : 10,
    "attack" : 2
  },
  "troll" : {
    "hp" : 9,
    "attack" : 1
  }
}

这是html：

<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title>Text Game</title>
    <link rel="stylesheet" type="text/css" href="style.css">
    <link href="https://fonts.googleapis.com/css?family=IBM+Plex+Sans+Condensed:400,400i,600" rel="stylesheet">
    <link rel="shortcut icon" href="favicon.ico" />
  </head>
  <body>

      <div id="game-text">
        <h3> Welcome to My Text Based Adventure!! </h3>
     </div>
    <input id="user-input"placeholder="Enter Commands"> </input>
    <script type="text/javascript" src="https://code.jquery.com/jquery-2.2.4.min.js"> </script>

    <script type="text/javascript" src="rooms.js"></script>

    <script type="text/javascript" src="script.js"></script>
  </body>
</html>

我希望输出对健康产生警报，但永远不会发生

/* fix me, how am I called? */
switch (command) {
  case "go":
    var dir = input.split(" ")[1];
    changeRoom(dir);
    break;

    showHelp();

  case "inventory":
    showInventory();
    break;
  case "take":
    var item = input.split(" ")[1];
    takeItem(item);
    break;
  case "fight":
    var en = input.split(" ")[1];
    fight(en);
    break;

    alert("invalid move!");

  },

}

如何在用jQuery编写的基于文本的游戏中实现战斗功能？
