標題[程式] 關於Unity的AssetBundle
時間Thu Jun 13 09:41:23 2013
各位前輩好，小弟弟我目前正在學著使用Unity的AssetBundle來做android的obb檔
但碰到一個小問題，希望各位前輩能指點指點....
我照著Unity提供的GooglePlayDownloader的說明來產生obb檔
1) Create one or many AssetBundles with the application data
(enough to get the .apk below the 50MB limit).
2) Concatenate the generated AssetBundles into a single .obb
by ZIP'ing them, using STORE (not DEFLATE).
$> zip -0 main.obb assetbundles
3) Continue to use WWW.LoadFromCacheOrDownload()
as with regular asset bundle loading, but use the path
to the .obb instead, like this:
WWW.LoadFromCacheOrDownload("jar:file://" +
obbPath +
"!/" + originalAssetBundleName);
在第二步驟時，我把三個assetbundle壓縮成一個main.obb檔，
這三個assetbundle分別是
RedCube.assetbundles,
GreenCube.assetBundles,
BuleCube.assetBundles
但在第三步驟時出現問題，
當我在Editor測試時，使用
string obbPath = "jar:file://"+
Application.dataPath +
"/../_AssetBunldes/main.obb!/RedCube.assetBundles";
WWW bundle = WWW.LoadFromCacheOrDownload(obbPath, 0);
Debug.Log(bundle.assetBundle);
會出現下方的錯誤
You are trying to load data from a www stream
which had the following error when downloading.
Resolving host timed out: jar:file:
UnityEngine.WWW:get_assetBundle()
<loadBundle>c__Iterator0:MoveNext() (at Assets/DownloadObbExample.cs:62)
當我在機器上測試時，我把路徑改成，
string mainPath = GooglePlayDownloader.GetMainOBBPath(expPath);
string obbPath = "jar:file://"+ mainPath + "!/RedCube.assetBundles";
WWW bundle = WWW.LoadFromCacheOrDownload(obbPath, 0);
Debug.Log(bundle.assetBundle);
這樣不會有錯誤訊息，但也不會秀出log
想請教一下，是我那裡做錯了嗎??
謝謝各位的幫忙!!

1F：推 holymars:Editor認不得jar:這種uri 有錯是正常的 06/13 21:34
原來如此，感謝提醒
2F：→ holymars:在機器上要是沒跑到Debug那行一定是有錯誤訊息你漏了才對 06/13 21:35
3F：推 holymars:另外WWW class你要檢查isDone 才能拿東西吧 就算在local 06/13 21:37
4F：→ holymars:端的檔案也一樣.. 06/13 21:37
原來是要加，因為之前測試時有加一樣沒有印出LOG，以為是卡死在迴圈內
所以把isDone拿掉了..感謝你的幫忙!!!^^
