需求描述

? ? ? ? 在游戲開發(fā)中，音頻資源是不可或缺的，通常情況下音頻資源隨機分布，各個音頻的操作和管理都是各自負責(zé)，同時對于音頻的很多操作邏輯都是大同小異的，這就造成了許多冗余代碼的堆疊，除此之外在獲取各類音頻資源的時候也會造成不必要的開銷。所以解決資源分散的問題最直接的方式就是集中管理和分配，通過統(tǒng)一的渠道和特有標識即可獲取或操作對應(yīng)的音頻資源。所以本篇文章將圍繞這個方案進行嘗試。

功能描述

? ? ? ? 在Unity中我們導(dǎo)入的音頻資源都會轉(zhuǎn)換為AudioClip，音頻的設(shè)置和管理則由AudioSource負責(zé)，AudioListener負責(zé)監(jiān)聽音頻。我們可以在此基礎(chǔ)上去封裝，從而打造一個音頻管理器。

????????音頻管理器負責(zé)管理音頻信息以及操作音頻，比如音頻信息的增加和刪除，音頻的播放和暫停等；

????????音頻信息可以使用一個單獨的實體類來記錄，用于記錄AudioSource組件中的信息，之所以單獨用一個實體類來記錄音頻信息而不直接采用AudioSource，主要是可以通過業(yè)務(wù)需求去動態(tài)調(diào)整所要記錄的音頻信息，我們的實際開發(fā)中并非需要AudioSource中所有的信息，有時候僅僅需要其中的一部分，同時音頻信息可能涉及存儲，直接采用AudioSource可能無法與已經(jīng)開發(fā)好的存儲系統(tǒng)相互兼容，而實體類可以為其添加接口或繼承來兼容存儲系統(tǒng)；

????????AudioSource組件的管理可以通過一個組件池進行管理，我們知道AudioSource也是等同于一個音頻實體類，但是其同時也是一種組件，組件同樣作為一種資源，通常情況下相比簡單的實體類而言會帶來更大的開銷，例如一個場景中有十個游戲?qū)ο笥胁シ乓纛l的需求，那么按照傳統(tǒng)情況就需要每個游戲?qū)ο髵燧d一個AudioSource組件，但是實際運行中十個游戲?qū)ο蟛⒉灰欢ㄐ枰瑫r播放音頻，它們或許都存在各自觸發(fā)音頻播放的條件，我們只需要在游戲?qū)ο笮枰シ乓纛l時為其分配一個AudioSource組件即可，組件池則負責(zé)維護AudioSource組件的生產(chǎn)、獲取和歸還，進而減少資源開銷。

? ? ? ? 本質(zhì)上，AudioSource組件承擔(dān)的工作就是記錄音頻信息和操作音頻，我們現(xiàn)在將記錄工作分擔(dān)給音頻信息實體類，而操作音頻的工作則分擔(dān)給音頻管理器，例如音頻管理器的播放依舊是調(diào)用AudioSource的播放方法，在播放之前由音頻管理器去獲取AudioSource組件并且為之配置音頻信息，其它的音頻操作邏輯同理。
