十九、攻击任务(MissionCaseAttack.php)

按照舰队任务的编号,排在第一个的就是攻击任务。这个代码很长,看的时候要有耐心。
好在引用的内容并不是很多,并且给出了详细的注释,读者不会晕头转向。

function MissionCaseAttack ($FleetRow)
{
  global $user, $phpEx, $xnova_root_path, $pricelist, $lang, $resource, $CombatCaps;
   // 在舰队的记录中,fleet_start_time代表的不是出发时间,而是到达目的地时间
   // 代表出发时间的是start_time
   // 此外还有fleet_end_time 这个是回到家的时间
    // fleet_end_stay 这个是结束逗留的时间(联合防御和远征任务会用到)
    // 所以下面这个判断的意思是“舰队到达了目的地”,而不是“舰队起飞了”
    if ($FleetRow['fleet_start_time'] <= time()) {
    // fleet_mess是用来记录舰队的状态的,基本可以理解为是在前进途中还是返航途中
    // 但感觉利用得并不好,如果只有两个状态,可以用true 和 false来记录
    // 所以我把它设为了0,1,2三个状态,对于需要停留的任务,停留时就处于第三个状态
    if ($FleetRow['fleet_mess'] == 0) {
      // ↓↓ 这个判断是试探存放战斗数据的文件是否存在
