十八、舰队活动(flyingfleethandler.php)
在前文中我们曾经初步研究过舰队活动的源码,提到过舰队活动的触发。现在我进一步分析xnova中舰队活动,这些在本质上是由玩家触发的,并不是由定时器在进行定时计算。舰队活动的触发是在common.php中进行的,所以入口就在这文件中,代码如下:
//检查是否有到达目的地的舰队 $_fleets = doquery("select * from {{table}} where 'fleet_start_time' <= '".time()."';", 'fleets'); // or fleet_end_time <= ".time() //循环处理每个舰队 while ($row = mysql_fetch_array($_fleets)) { $array = array(); $array['galaxy'] = $row['fleet_start_galaxy']; $array['system'] = $row['fleet_start_system']; $array['planet'] = $row['fleet_start_planet']; $array['planet_type'] = $row['fleet_start_type']; //舰队处理函数 $temp = flyingfleethandler ($array); } //检查是否有返回出发地的舰队 $_fleets = doquery("select * from {{table}} where 'fleet_end_time' <= '".time()."';", 'fleets'); // or fleet_end_time <= ".time() //循环处理每个舰队 while ($row = mysql_fetch_array($_fleets)) { $array = array(); $array['galaxy'] = $row['fleet_end_galaxy']; $array['system'] = $row['fleet_end_system']; $array['planet'] = $row['fleet_end_planet']; $array['planet_type'] = $row['fleet_end_type']; //舰队处理函数 $temp = flyingfleethandler ($array); }
大家看到了,前面这段代码其实写的不好,因为这里每次都会被调用,效率太低了。因此我们在这里可以进行优化,使每次循环只需要一个舰队的id传递给函数即可;相应的函数也要做修改,有兴趣的自己修改下。
接下来看看函数flyingfleethandler(),这是集中调用舰队活动的函数。
//锁表,防止出现数据不同步等问题 doquery("lock table {{table}}lunas write, {{table}}rw write, {{table}}errors write, {{table}}messages write, {{table}}fleets write, {{table}}planets write, {{table}}galaxy write ,{{table}}users write", ""); //这里一大段就是取得舰队数组,参数完全可以使用舰队id,优化之 $qryfleet = "select * from {{table}} "; $qryfleet .= "where ("; $qryfleet .= "( "; $qryfleet .= "`fleet_start_galaxy` = ". $planet['galaxy'] ." and "; $qryfleet .= "`fleet_start_system` = ". $planet['system'] ." and "; $qryfleet .= "`fleet_start_planet` = ". $planet['planet'] ." and "; $qryfleet .= "`fleet_start_type` = ". $planet['planet_type'] ." "; $qryfleet .= ") or ( "; $qryfleet .= "`fleet_end_galaxy` = ". $planet['galaxy'] ." and "; $qryfleet .= "`fleet_end_system` = ". $planet['system'] ." and "; $qryfleet .= "`fleet_end_planet` = ". $planet['planet'] ." ) and "; $qryfleet .= "`fleet_end_type`= ". $planet['planet_type'] ." ) and "; $qryfleet .= "( `fleet_start_time` < '". time() ."' or `fleet_end_time` < '". time() ."' );"; $fleetquery = doquery( $qryfleet, 'fleets' ); //根据舰队活动的目标不同,分别进入不同的函数处理 while ($currentfleet = mysql_fetch_array($fleetquery)) { switch ($currentfleet["fleet_mission"]) { case 1: // 普通攻击 missioncaseattack ( $currentfleet ); break; case 2: // 这里应该是acs攻击或者是其他攻击,但是现在没有用 doquery ("delete from {{table}} where `fleet_id` = '". $currentfleet['fleet_id'] ."';", 'fleets'); break; case 3: // 运输 missioncasetransport ( $currentfleet ); break; case 4: // 派遣 missioncasestay ( $currentfleet ); break; case 5: // 联合派遣,即acs防御 missioncasestayally ( $currentfleet ); break; case 6: // 侦查 missioncasespy ( $currentfleet ); break; case 7: // 殖民 missioncasecolonisation ( $currentfleet ); break; case 8: // 回收 missioncaserecycling ( $currentfleet ); break; case 9: // 毁月,厉害了 missioncasedestruction ( $currentfleet ); break; case 10: // 保留 !! break; case 15: // 远征、探险 missioncaseexpedition ( $currentfleet ); break; //其他情况删除舰队,这个是好习惯 default: { doquery("delete from {{table}} where `fleet_id` = '". $currentfleet['fleet_id'] ."';", 'fleets'); } } } //解锁表 doquery("unlock tables", "");
上面的函数结构清晰,代码明了,注释也讲的很清楚了。
