十八、艦隊(duì)活動(dòng)（FlyingFleetHandler.php）

在前文中我們?cè)?jīng)初步研究過艦隊(duì)活動(dòng)的源碼，提到過艦隊(duì)活動(dòng)的觸發(fā)。現(xiàn)在我進(jìn)一步分析Xnova中艦隊(duì)活動(dòng)，這些在本質(zhì)上是由玩家觸發(fā)的，并不是由定時(shí)器在進(jìn)行定時(shí)計(jì)算。艦隊(duì)活動(dòng)的觸發(fā)是在common.php中進(jìn)行的，所以入口就在這文件中，代碼如下：

//檢查是否有到達(dá)目的地的艦隊(duì)$_fleets = doquery("SELECT * FROM {{table}} WHERE 'fleet_start_time' <= '".time()."';", 'fleets'); // OR fleet_end_time <= ".time()//循環(huán)處理每個(gè)艦隊(duì)while ($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'] = $row['fleet_start_type'];//艦隊(duì)處理函數(shù)$temp = FlyingFleetHandler ($array);}//檢查是否有返回出發(fā)地的艦隊(duì)$_fleets = doquery("SELECT * FROM {{table}} WHERE 'fleet_end_time' <= '".time()."';", 'fleets'); // OR fleet_end_time <= ".time()//循環(huán)處理每個(gè)艦隊(duì)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'] = $row['fleet_end_type'];//艦隊(duì)處理函數(shù)$temp = FlyingFleetHandler ($array);}

大家看到了，前面這段代碼其實(shí)寫的不好，因?yàn)檫@里每次都會(huì)被調(diào)用，效率太低了。因此我們?cè)谶@里可以進(jìn)行優(yōu)化，使每次循環(huán)只需要一個(gè)艦隊(duì)的ID傳遞給函數(shù)即可；相應(yīng)的函數(shù)也要做修改，有興趣的自己修改下。

接下來看看函數(shù)FlyingFleetHandler（），這是集中調(diào)用艦隊(duì)活動(dòng)的函數(shù)。

//鎖表，防止出現(xiàn)數(shù)據(jù)不同步等問題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", "");//這里一大段就是取得艦隊(duì)數(shù)組，參數(shù)完全可以使用艦隊(duì)ID，優(yōu)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( $QryFleet, 'fleets' );//根據(jù)艦隊(duì)活動(dòng)的目標(biāo)不同，分別進(jìn)入不同的函數(shù)處理while ($CurrentFleet = mysql_fetch_array($fleetquery)) { switch ($CurrentFleet["fleet_mission"]) { case 1:  // 普通攻擊  MissionCaseAttack ( $CurrentFleet );  break; case 2:  // 這里應(yīng)該是ACS攻擊或者是其他攻擊，但是現(xiàn)在沒有用  doquery ("DELETE FROM {{table}} WHERE `fleet_id` = '". $CurrentFleet['fleet_id'] ."';", 'fleets');  break; case 3:  // 運(yùn)輸  MissionCaseTransport ( $CurrentFleet );  break; case 4:  // 派遣  MissionCaseStay ( $CurrentFleet );  break; case 5:  // 聯(lián)合派遣，即ACS防御 MissionCaseStayAlly ( $CurrentFleet );  break; case 6:  // 偵查  MissionCaseSpy ( $CurrentFleet );  break; case 7:  // 殖民  MissionCaseColonisation ( $CurrentFleet );  break; case 8:  // 回收  MissionCaseRecycling ( $CurrentFleet );  break; case 9:  // 毀月，厲害了  MissionCaseDestruction ( $CurrentFleet );  break; case 10:  // 保留 !!   break; case 15:  // 遠(yuǎn)征、探險(xiǎn)  MissionCaseExpedition ( $CurrentFleet );  break; //其他情況刪除艦隊(duì)，這個(gè)是好習(xí)慣 default: {  doquery("DELETE FROM {{table}} WHERE `fleet_id` = '". $CurrentFleet['fleet_id'] ."';", 'fleets'); } }}//解鎖表doquery("UNLOCK TABLES", "");

上面的函數(shù)結(jié)構(gòu)清晰，代碼明了，注釋也講的很清楚了。
