Question

我只是遇到了一个简单的问题，但似乎无法找到解决方案。以下代码是开源项目的一部分，但这部分是我从头开始编写的。

嗯，这个“脚本”里面的所有内容都可以正常运行，除了一件事，调用int方法后，CB_State变量StartParticipation()不会更改：

import java.util.Calendar;
import java.util.logging.Logger;
import com.l2jserver.gameserver.Announcements;
import com.l2jserver.gameserver.ThreadPoolManager;
import com.l2jserver.gameserver.model.actor.instance.L2PcInstance;
import com.l2jserver.gameserver.network.serverpackets.NpcHtmlMessage;

public final class CastleBattle
{
    private static Logger _log = Logger.getLogger("CastleBattle");

    private static String htm_path = "data/scripts/l2dc/CastleBattle/";
    public static int CB_State = 1; // 0 - Disabled, 1 - Not running, 2 - Participation start, 3 - Participation end, 4 - Running, 5 - Event ended

    public CastleBattle()
    {
        CB_Init();
    }

    // Initialize Engine
    private static void CB_Init()
    {
        if (CB_State == 1)
        {
            SetStartTime();
        }
    }

    // Event Loop
    public static void SetStartTime()
    {
        Calendar _nextTime = Calendar.getInstance();
        int _m = _nextTime.get(Calendar.MINUTE);
        int x = 1;
        while (_m > 5)
        {
            _m -= 5;
            x++;
        }
        _nextTime.set(Calendar.MINUTE, x * 5);
        ThreadPoolManager.getInstance().scheduleGeneral(new CastleBattleLoop(), _nextTime.getTimeInMillis() - System.currentTimeMillis());
    }

    // Allow players to participate in the event
    public static void StartParticipation()
    {
        CB_State = 2;
        Announcements.getInstance().announceToAll("Castle Battle participation has started.");
        _log.info("Castle Battle participation has started.");
    }

    // Player requests to join event via NPC
    public static void CB_bypass(String _cmd, L2PcInstance _player)
    {
        if (_cmd.startsWith("InitHtmlRequest"))
        {
            if (CB_State == 0)
            {
                NpcHtmlMessage _html = new NpcHtmlMessage(0);
                _html.setFile("", htm_path + "CB_Disabled.htm");
                _player.sendPacket(_html);
            }
            if (CB_State == 1)
            {
                NpcHtmlMessage _html = new NpcHtmlMessage(0);
                _html.setFile("", htm_path + "CB_NotRunning.htm");
                _player.sendPacket(_html);
            }
            if (CB_State == 2)
            {
                NpcHtmlMessage _html = new NpcHtmlMessage(0);
                _html.setFile("", htm_path + "CB_Participate.htm");
                _player.sendPacket(_html);
            }
        }
    }

    public static void main(String[] args)
    {
        _log.info("# Castle Battle Engine #");
        _log.info("Author : HyperByter");
        _log.info("Version : Beta");
        _log.info("Version : 3.7.2013");
        new CastleBattle();
    }
}

class CastleBattleLoop implements Runnable
{
    @Override
    public void run()
    {
        if (CastleBattle.CB_State == 1)
        {
            CastleBattle.StartParticipation();
        }
    }
}

那么有任何建议如何解决这个问题？

Answer 1

方法StartParticipation()可能永远不会被调用：

main()调用CastleBattle
CastleBattle构造函数调用CB_Init()
CB_Init()来电SetStartTime()

SetStartTime()调用此行：

ThreadPoolManager.getInstance().scheduleGeneral(new CastleBattleLoop(), _nextTime.getTimeInMillis() - System.currentTimeMillis());

在对_nextTime进行了一些严厉且难以理解的算术之后，调度间隔可能非常大或者可能是负数，这可能导致Runnable CastleBattleLoop永远不会启动，在这种情况下StartParticipation（）永远不会被召唤。

我不知道ThreadPoolManager对奇怪的输入做了什么，但我首先要调试传递给scheduleGeneral（）方法的值，然后读取javadoc以查看这样的值会产生什么影响。

Answer 2

底部的类称为CastleBattleLoop，但它不包含任何循环，因此StartParticipation()只被调用一次（如果此时CB_State为1）。

您应该添加类似

的内容

while(running){
    if (CastleBattle.CB_State == 1)
    {
        CastleBattle.StartParticipation();
    }
    Thread.sleep(100);
}

Answer 3

在线程内调用StartParticipation（）。检查您是否在实际更改发生之前试图找出其值。

[不知道你是如何在代码的后半部分找出“CastleBattle.CB_State”的值]

在函数中赋值后，整数值不会更改
