标题[程式] 关於Unity的AssetBundle
时间Thu Jun 13 09:41:23 2013
各位前辈好，小弟弟我目前正在学着使用Unity的AssetBundle来做android的obb档
但碰到一个小问题，希望各位前辈能指点指点....
我照着Unity提供的GooglePlayDownloader的说明来产生obb档
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);
在第二步骤时，我把三个assetbundle压缩成一个main.obb档，
这三个assetbundle分别是
RedCube.assetbundles,
GreenCube.assetBundles,
BuleCube.assetBundles
但在第三步骤时出现问题，
当我在Editor测试时，使用
string obbPath = "jar:file://"+
Application.dataPath +
"/../_AssetBunldes/main.obb!/RedCube.assetBundles";
WWW bundle = WWW.LoadFromCacheOrDownload(obbPath, 0);
Debug.Log(bundle.assetBundle);
会出现下方的错误
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)
当我在机器上测试时，我把路径改成，
string mainPath = GooglePlayDownloader.GetMainOBBPath(expPath);
string obbPath = "jar:file://"+ mainPath + "!/RedCube.assetBundles";
WWW bundle = WWW.LoadFromCacheOrDownload(obbPath, 0);
Debug.Log(bundle.assetBundle);
这样不会有错误讯息，但也不会秀出log
想请教一下，是我那里做错了吗??
谢谢各位的帮忙!!

1F：推 holymars:Editor认不得jar:这种uri 有错是正常的 06/13 21:34
原来如此，感谢提醒
2F：→ holymars:在机器上要是没跑到Debug那行一定是有错误讯息你漏了才对 06/13 21:35
3F：推 holymars:另外WWW class你要检查isDone 才能拿东西吧 就算在local 06/13 21:37
4F：→ holymars:端的档案也一样.. 06/13 21:37
原来是要加，因为之前测试时有加一样没有印出LOG，以为是卡死在回圈内
所以把isDone拿掉了..感谢你的帮忙!!!^^
