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。
