Obsolete public static bool BuildAssetBundle(Object mainAsset, Object[] assets, string pathName, BuildAssetBundleOptions assetBundleOptions, BuildTarget targetPlatform);
Obsolete public static bool BuildAssetBundle(Object mainAsset, Object[] assets, string pathName, out uint crc, BuildAssetBundleOptions assetBundleOptions, BuildTarget targetPlatform);


mainAssetLets you specify a specific object that can be conveniently retrieved using AssetBundle.mainAsset.
assetsAn array of assets to write into the bundle.
pathNameThe filename where to write the compressed asset bundle.
assetBundleOptionsAutomatically include dependencies or always include complete assets instead of just the exact referenced objects.
targetPlatformThe platform to build the bundle for.
crcThe optional crc output parameter can be used to get a CRC checksum for the generated AssetBundle, which can be used to verify content when downloading AssetBundles using UnityWebRequestAssetBundle.GetAssetBundle.


Builds an asset bundle.

Creates a compressed unity3d file that contains a collection of assets. AssetBundles can contain any asset found in the project folder. This lets you stream resource data of any type, fully setup Prefabs, textures, meshes, animations, any type of asset shown in the project window.
All paths are relative to the project folder. Like: "Assets / MyTextures / hello.png".

Note that asset bundles built for standalone targets cannot be loaded by applications built for mobile platforms and vice versa. Furthermore, bundles are not compatible between iOS and Android platforms.

The function returns a boolean value which is true if the build succeeded and false otherwise.

BuildAssetBundle has been made obsolete. Please use the new AssetBundle build system introduced in 5.0 and check BuildAssetBundles documentation for details.
