十八、艦隊活動（FlyingFleetHandler.php）
在前文中我們曾經初步研究過艦隊活動的源碼，提到過艦隊活動的觸發。現在我進一步分析Xnova中艦隊活動，這些在本質上是由玩家觸發的，并不是由定時器在進行定時計算。艦隊活動的觸發是在common.php中進行的，所以入口就在這文件中，代碼如下：

大家看到了，前面這段代碼其實寫的不好，因為這里每次都會被調用，效率太低了。因此我們在這里可以進行優化，使每次循環只需要一個艦隊的ID傳遞給函數即可；相應的函數也要做修改，有興趣的自己修改下。
接下來看看函數FlyingFleetHandler（），這是集中調用艦隊活動的函數。

上面的函數結構清晰，代碼明了，注釋也講的很清楚了。
