实例1：完成玩家加入游戏时的通告。

伪代码

public class JoinPlugin extends JavaPlugin implements Listener {


JexlScript joinEvent;
		
    onEnable(){
    	registerListener(this,this);
    }

    @EventHandler
    public void on(PlayerJoinEvent event) {
        if (this.joinEvent != null) {
            JexlScriptHelper.runScript(joinEvent, MapUtils.of("Event", event));
        }
    }
    
    onReload(){
    	getConfig().reloadConfig();
      // 这一步比较耗时
      joinEvent = com.germ.germplugin.api.script.JexlScriptHelper.initScript(getConfig().getString("event-join"));
    }
}

配上这个配置文件 config.yml

event-join: |
  var player = Event.getPlayer();
  if(player.hasPermission("group.vip10")){
    Event.setJoinMessage("§7[§6VIP10§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip9")){
    Event.setJoinMessage("§7[§6VIP9§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip8")){
    Event.setJoinMessage("§7[§6VIP8§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip7")){
    Event.setJoinMessage("§7[§6VIP7§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip6")){
    Event.setJoinMessage("§7[§6VIP6§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip5")){
    Event.setJoinMessage("§7[§6VIP5§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip4")){
    Event.setJoinMessage("§7[§6VIP4§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip3")){
    Event.setJoinMessage("§7[§6VIP3§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip2")){
    Event.setJoinMessage("§7[§6VIP2§7] §e" + player.getName() + " §7加入了游戏");
  }else if(player.hasPermission("group.vip1")){
    Event.setJoinMessage("§7[§6VIP1§7] §e" + player.getName() + " §7加入了游戏");
  }else{
    Event.setJoinMessage(null);
  }
