九、公共代码(common.php)

Common.php是Xnova的公共代码,几乎每次点击都会被执行,所以这里要是优化的好,那么整个程序的效率都会有提升;当然这个文件调用的其他代码也要一并优化才行。

$game_config  = array();
$user     = array();
$lang     = array();
$link     = "";
$IsUserChecked = false; 
Copy after login

变量$game_config存放整个游戏的参数数据,每次都要读数据库,可以优化,优化方式比如保存在文件里面;变量$user存放登录的用户数据;$lang存放的是本地语言数据;$IsUserChecked记录是否check过用户。然后设置一些系统常量,在以后的代码中都要使用到的;再include一些函数文件,有以前我们介绍过的小函数在里面等。


接下来就要用到一个常量INSTALL,这个是在安装的时候定义的;除了安装的时候,这个判断都会进入。进入之后,又include一些文件,其中的includes/vars.php文件很重要,我将专门讲解,现在继续。这里还要从数据库中取得数据,并填充变量$game_config。

if ($InLogin != true) {
 $Result    = CheckTheUser ( $IsUserChecked );
 $IsUserChecked = $Result['state'];
 $user     = $Result['record'];
} elseif ($InLogin == false) {
 if( $game_config['game_disable']) {
 if ($user['authlevel'] < 1) {
  message ( stripslashes ( $game_config['close_reason'] ), $game_config['game_name'] );
 }
 }
}
Copy after login

以上是检查保存在cookie里面的用户登录数据的,在$InLogin = true的时候,不会执行;现在我们讲到的是用户平时操作,所以这里$InLogin的值为false。首先调用函数CheckTheUser(),参数$IsUserChecked的值为false;CheckTheUser()声明在 includes/functions/CheckUser.php文件中,它又调用了声明在 includes/functions/CheckCookies.php中的CheckCookies()函数。而函数CheckCookies() 的功能就是使用Cookie中的信息来check用户,代码我就不列出了。

如果CheckTheUser()成功,那么变量$user里面就填充好了用户的数据,然后执行下面的分支。这个分支是检查服务器参数设置的,如果服务器被管理员设置为关闭,则检查用户的权限;如果权限不够,则显示错误消息。


然后就要处理的是用户活动中的舰队了,分为两段逻辑:

1.当前时间大于舰队抵达目的地的时间,需要处理发生战斗、运输等逻辑

2.当前时间大于舰队返回出发地的时间,同样要处理发生战斗后、运输后的舰队回归逻辑

每个活动都调用函数FlyingFleetHandler()来处理,此函数我们以后再分析,现在只要知道功能就行了。如果用户点击频繁的话,这段逻辑将是非常耗资源的,所以这里也可以优化,比如缓存或者不是每次都执行等等。

舰队活动处理完了,那么导弹的活动呢怎么办?接下来的rak.php文件就是用来处理星际导弹的。文件功能包括了导弹的拦截、导弹摧毁的防御数量、发送消息给被攻击方等。具体逻辑我们也略过,以后分析。

然后调用函数SetSelectedPlanet()取得玩家上次所在的星球,注意这个函数的参数,是传址的,函数声明在includes/functions/SetSellectPlanet.php。接下来的要取得两个变量值,$planetrow存放用户当前星球的数据;$galaxyrow存放当前星球的星系坐标数据。

最后调用函数CheckPlanetUsedFields()更新当前星球的使用空间,同样参数是传址的,声明在 includes/functions/CheckPlanetUsedFields.php。

Common.php文件分析完了,如果大家理解了的话,就应该知道这里的效率很重要;希望大家一起来优化,其他部分也同样。
