循环公告+显示当前在线人数

找到：net.sf.odinms.scripting.event EventManager.java

导入3个包：
import java.sql.*;
import java.sql.ResultSet;
import net.sf.odinms.database.DatabaseConnection;

找到最后一个大括号在前面添加
public int Lianjie()
        {
            Connection con = DatabaseConnection.getConnection();
            PreparedStatement ps;
            ResultSet re;
            int count=0;
        try {
            ps = con.prepareStatement("SELECT count(*) as cc FROM accounts WHERE loggedin = 2");
            re=ps.executeQuery();
            while(re.next())
            {
                count = re.getInt("cc");
            }
            //ps.close();
          //  con.close();
        } catch (SQLException ex) {
            Logger.getLogger(EventInstanceManager.class.getName()).log(Level.SEVERE, null, ex);
        }
            return count;
        }

保存编译

然后就需要循环公告的JS了

/*
  循环公告+显示在线人数 BY annfine
  在\scripts\event中新建AutoMsg.js
  在world.properties中的加入该事件，例如：
  net.sf.odinms.channel.events=lolcastle,3rdjob,Boats,Trains,Flights,Subway,KerningPQ,ZakumPQ,GuildQuest,LudiPQ,AutoMsg
*/
var setupTask;
function init() {
    scheduleNew();
}
function scheduleNew() {
    var cal = java.util.Calendar.getInstance();
    cal.set(java.util.Calendar.HOUR, 3);
    cal.set(java.util.Calendar.MINUTE, 50);
    cal.set(java.util.Calendar.SECOND, 0);
    var nextTime = cal.getTimeInMillis();
    while (nextTime <= java.lang.System.currentTimeMillis()) {
        nextTime += 60 * 10 * 1 * 1; // Every 1 hour. 公告循环时间
    }
    setupTask = em.scheduleAtTimestamp("start", nextTime);
}
function cancelSchedule() {
    setupTask.cancel(true);
}
function start() {
    scheduleNew();
var Message = new Array(

);
    em.getChannelServer().broadcastPacket(
        net.sf.odinms.tools.MaplePacketCreator.serverNotice(6, "友情提示 : " + Message[Math.floor(Math.random() * Message.length)]));
    var iter = em.getInstances().iterator();
    while (iter.hasNext()) {
        var eim = iter.next();
    }
