一、Unity中的路徑變量
- Application.dataPath
應(yīng)用數(shù)據(jù)文件夾的路徑，只讀樟遣。 - Application.streamingAssetsPath
應(yīng)用的流式數(shù)據(jù)緩存目錄，該目錄下可以保存一些外部數(shù)據(jù)文件。 - Application.temporaryCachePath
設(shè)備的臨時(shí)數(shù)據(jù)緩存目錄含懊。 - Application.persistentDataPath
iOS/Android設(shè)備中的持久化數(shù)據(jù)存儲(chǔ)目錄，可以在此路徑下存儲(chǔ)一些持久化的數(shù)據(jù)文件衅胀，該目錄下的文件不會(huì)因?yàn)锳pp升級(jí)而刪除岔乔。
二、不同平臺(tái)下的路徑
| 路徑變量 | Windows | Android | iOS |
| :------------ | :---------------- | :------------ | :---------- | :---------- |
| Application.dataPath | 應(yīng)用的路徑/appname _Data | /data/app/package name-1/base.apk | /var/containers/Bundle/Application/app sandbox/xxx.app/Data |
| Application.streamingAssetsPath | 應(yīng)用路徑/appname _Data /StreamingAssets | jar:file:///data/app/package name-1/base.apk!/assets | /var/containers/Bundle/Application/app sandbox/test.app/Data/Raw |
| Application.temporaryCachePath | C:\Users\username\AppData\Local\Temp\company name\product name | Internal Only: /data/user/0/package name/cache External(SDCard): /storage/emulated/0/Android/data/package name/cache | /var/mobile/Containers/Data/Application/app sandbox/Library/Caches |
| Application.persistentDataPath | C:\Users\username\AppData\LocalLow\company name\product name | Internal Only: /data/user/0/ package name/files External(SDCard): /storage/emulated/0/Android/data/package name/files | /var/mobile/Containers/Data/Application/app sandbox/Documents |
說(shuō)明：Android平臺(tái)下的路徑會(huì)根據(jù)SD卡的訪問(wèn)權(quán)限不同而不同滚躯。至于iOS有沒(méi)有類似的情況雏门，由于沒(méi)有相關(guān)設(shè)備，暫時(shí)沒(méi)有測(cè)試掸掏。有條件的朋友可以幫我測(cè)試一下茁影，我用5.3.4f1版本的Unity寫(xiě)了個(gè)簡(jiǎn)單的測(cè)試程序，項(xiàng)目鏈接：http://pan.baidu.com/s/1gfqmORh丧凤。 歡迎測(cè)試反饋募闲，不勝感激！
