AssetBundles and mainAsset null - v5

AssetBundles changed with 5 but there appears to be no explanation of the mainAsset changes - this variable has no concept in v5 I have read (correct?) yet no warning is given that it will now be null in a v5 asset bundle, nor can you tell if the asset bundle was built with 5 or prior on loading.

I would suggest a depreciated warning for using AssetBundle.mainAsset if it really is irrelevant in v5 bundles. Though personally I would prefer if it just pointed to the first asset in any bundle...

 

I agree. andyz post here is the only information we have on mainAsset and new build API.

 

In 5.3.3, I'm noticing an exception being through by even getting the mainAsset.. not even trying to access it: Debug.Log(asset_bundle.mainAsset);

I started using something like: asset_bundle.LoadAllAssets()[0], but not sure if this is the correct way to go.

There's no documentation on this seemingly breaking change (or at least I can't seem to find it anywhere). Wish we had some more info on this.

 

Sorry for the trouble, we added obsolete warning messages to the old asset bundle build APIs, but apparently we missed this property. Will take care of this.
