这篇文章主要介绍了PHP网页游戏Xnova(ogame)源码解读的舰队活动页面处理流程,需要的朋友可以参考下

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。
