你好再次stackoverflow！由于某种原因，我在使用这个插件时遇到了最困难的时间。以下是问题。所以它有一个带有方法勾选的游戏类，我会发布它，但它似乎无法正常工作，它根本不会向玩家发送调试消息！然后我注意到保存类游戏的列表上有一个 ConcurrentModificationException。老实说，我不确定是什么导致了 ConcurrentModificationException，因为我浏览了我的代码，并且似乎没有在迭代中修改列表。我真的不想展示我所有的代码，但我觉得我需要展示一些。如果您可以查看这些部分并尝试对此有所了解，我将不胜感激！如果有人能指出是什么导致了 ConcurrentModificationException 那就太棒了，如果有人能向我解释为什么 p.sendMessage("test!"); 剂量似乎根本没有发生。

ConcurrentModificationException 已修复！

从类主段：

public class Main extends JavaPlugin implements Runnable {
//Holds all active games
public static ArrayList<Game> games = new ArrayList<Game>();
private CommandHandler cmdHandler = new CommandHandler(this);
private Thread thread = new Thread(this);
private boolean serverActive = true;

public void onEnable(){
    //Command stuff here 
    thread.start();
}

public void onDisable(){
    serverActive = false;
}

@Override
public void run() {
    //Loop through games.
    while(serverActive == true){
        for (Game game: games){
            game.Tick();
        }
    }
}

}

来自命令处理程序的段：新游戏命令上发生 ConcurrentModificationException 错误

@Override
public boolean onCommand(CommandSender sender, Command arg, String cmd, String[] args){
    if (cmd.equalsIgnoreCase("newgame")){
        if (args.length == 0){
            sender.sendMessage(ChatColor.RED + "Please enter a game name.");
            return true;
        }else{
        Player player = sender.getServer().getPlayer(sender.getName());
                //Loop and Check
                Game game;
                for (int i = 0; i < Main.games.size(); i++){
                    game = Main.games.get(i);
                    if (game.getName().equalsIgnoreCase(args[0])){
                        //Tells that a game already exists with that name.
                        player.sendMessage(ChatColor.RED + "Can not create game with the name of " + args[0]);
                        return true;
                    }
                }   
                // We have reached the end of the loop so we now know that none of the 
                // games in the list match. Now we can return.
                Main.games.add(new Game(args[0],sender.getServer().getPlayer(sender.getName())));
                player.sendMessage(ChatColor.GREEN + "Game Created. To join Type " + ChatColor.ITALIC + "/join " + args[0]);
                return true;
            }

游戏类的片段：

//Teams
public ArrayList<Player> terrorists = new ArrayList<Player>();
private ArrayList<Player> traitors = new ArrayList<Player>();

public Game(String gameName, Player gameOwner){
    this.gameName = gameName;
    this.gameOwner = gameOwner;
    state = State.Idle;
}

public void Tick(){
        if (state == State.Active){
            //Perform while Active Game.


        }else if (state == State.Idle){
            //Perform while Idle Game.
            for (Player p: terrorists){
                p.sendMessage("test!");
            }
        }else{
            //Clean up
            terrorists.clear();
            traitors.clear();
        }
}

现在您的 ConcurrentModificationException 已修复，您还有这个问题吗？

在您提供的代码段中，我看不到您将玩家添加到游戏恐怖分子列表的任何地方。因此，即使游戏正在运行，也没有人可以向其发送消息。

此外，也许通过向您的 Player 或游戏的创建者发送硬编码消息进行调试会有所帮助。这将显示游戏是否正确注册了玩家。

myWorld.getPlayer(*yournickname*).sendMessage("Game tick!");

for (Player p: terrorists) {
    p.sendMessage("test! You are a terrorist!");
}
