這篇文章主要介紹了PHP網(wǎng)頁游戲Xnova(ogame)源碼解讀的艦隊(duì)活動(dòng)頁面處理流程,需要的朋友可以參考下

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)?，F(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)
$_fleets = doquery("SELECT * FROM {{table}} WHERE 'fleet_start_time' &lt;= '".time()."';", 'fleets'); // OR fleet_end_time &lt;= ".time()
//循環(huán)處理每個(gè)艦隊(duì)
while ($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)
$_fleets = doquery("SELECT * FROM {{table}} WHERE 'fleet_end_time' &lt;= '".time()."';", 'fleets'); // OR fleet_end_time &lt;= ".time()
//循環(huán)處理每個(gè)艦隊(duì)
while ($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。
