基本設(shè)置
Profile文件中配置資源構(gòu)建路徑和資源首次加載路徑，資源如何設(shè)置了緩存，在首次加載之后會(huì)將再用緩存在緩存目錄，后面將直接從緩存目錄中讀取，方便項(xiàng)目發(fā)包時(shí)候進(jìn)行使用
AddressableAssetSettings文件
DisableCatalogUpdateOnStartup 勾選改選項(xiàng)，禁止自動(dòng)更新，項(xiàng)目資源下載一般需要提示玩家下載資源大小和下載進(jìn)度，需要通過(guò)代碼進(jìn)行手動(dòng)下載更新
BuildRemoteCatalog 創(chuàng)建遠(yuǎn)端資源的catalog，用于熱更新資源
設(shè)置BuildPath和 LoadPath
根據(jù)自身網(wǎng)絡(luò)狀況設(shè)置資源最大的請(qǐng)求數(shù)和下載超時(shí)時(shí)間
Group文件注意設(shè)置BundleMode ,是否將group內(nèi)的資源分散打包
Remote資源緩存
unity自身默認(rèn)緩存路徑是 C:\Users\admin\AppData\LocalLow\Unity
Addressable默認(rèn)緩存路徑 C:\Users\admin\AppData\LocalLow\Unity\項(xiàng)目名稱_AdressableLoad
可以指定遠(yuǎn)端遠(yuǎn)端資源在本地緩存路徑，需要注意的是，如果項(xiàng)目剛開(kāi)始運(yùn)行的時(shí)候沒(méi)有手動(dòng)設(shè)置緩存目錄，在手動(dòng)添加緩存目錄之后默認(rèn)緩存目錄中已經(jīng)存在的資源并不會(huì)被釋放，每次加載讀取的時(shí)候，先從手動(dòng)設(shè)置的緩存目錄中查找，在從默認(rèn)緩存中查找，如果默認(rèn)緩存中存在資源，則不會(huì)重新進(jìn)行下載
創(chuàng)建CacheInitializationSettings文件，然后將改文件關(guān)聯(lián)到AddressableAssetSettings的inititalizationObjects中，方法如下
手動(dòng)設(shè)置緩存路徑（如下圖所示方式會(huì)緩存在工程根目錄的AAAAAAA文件夾內(nèi)，也可設(shè)置為 persistentDataPath 格式為{UnityEngine.Application.persistentDataPath}）
每一個(gè)下載下來(lái)的bundle資源，會(huì)被緩存為_(kāi)data 和_info兩個(gè)文件，（猜測(cè)：_info是索引文件信息，_data是資源序列化內(nèi)容）
