从迭代器 Bukkit 1.16.5 中获取播放器

如何解决从迭代器 Bukkit 1.16.5 中获取播放器

我有一个问题，今天让我很沮丧，我创建了一个插件，在点击库存时将玩家添加到数组列表中（不幸的是我这样做了，因为我不是很好），游戏只有一个并且包含 2 个玩家，我不能确定如果一个玩家退出，通过一个方法，他可以让另一个玩家获胜，我尝试了很多方法，这是最后一个（在下面的这段代码中，我尝试将一种方法，如果我远程理解它应该向玩家发送胜利消息，显然它不会，然后执行 LobbyJoin，这是一种将您带到大厅的方法）：

private void makeWinSupport(Player winner,Player loser) {
    if (playerInGame.contains(winner) && playerInGame.contains(loser)) {
        winner.sendMessage(plugin.cc("&6(!) Hai vinto!"));
        LobbyJoin(loser);
        LobbyJoin(winner);
        playerInGame.remove(winner);
        playerInGame.remove(loser);
    }
}

public void makePlayerWin(Player loser) {
    Iterator<Player> i = playerInGame.iterator();
        System.out.println(1);
        if(i.hasNext() && i == loser) {
            makeWinSupport(i.next(),loser);

        } else {
            makeWinSupport(playerInGame.get(0),loser);
        }

    @EventHandler
public void onQuit(PlayerQuitEvent e) {
    e.setQuitMessage("");
    Player p = e.getPlayer();
    if(playerInGame.contains(p)) {
        makePlayerWin(p);
        }
    }
}

解决方法

当玩家离开时，您可以使用 PlayerQuitEvent 从您的插件中删除他们。我制作了这个示例，假设您有一个名为 yourPlayerList 的列表，其中存储了 2 个竞争玩家，但您可以对其进行修改以与更多玩家一起使用。

@EventHandler
public void onPlayerLeave(PlayerQuitEvent event) {
    if(yourPlayerList.remove(event.getPlayer())){//only true if the player was removed from the queue,which only happens if it was in the queue originally
        Player loser=event.getPlayer();//the loser
        Player winner=yourPlayerList.get(0);//the other player is still in the queue
        makeWinSupport(winner,loser);
    }
}

不要忘记在活动管理器中注册活动。

编辑：如果您想从列表中删除玩家并仅在仅剩一名玩家时结束游戏，您可以执行以下操作：

@EventHandler
public void onPlayerLeave(PlayerQuitEvent event) {
    if(yourPlayerList.remove(event.getPlayer())&&yourPlayerList.size()==1){//removes the player and checks the amount of active players
        Player winner=yourPlayerList.get(0);
        //here you can call a method which accepts only the winning player. If you have 4 players,there is no reason to include a 'loser' player.
    }
}
