AssetBundle.LoadFromFileAsync

Parameters

Returns

AssetBundleCreateRequest Asynchronous create request for an AssetBundle. Use assetBundle property to get an AssetBundle once it is loaded.

Description

Asynchronously loads an AssetBundle from a file on disk.

The function supports bundles of any compression type. In case of lzma compression, the data will be decompressed to the memory. Uncompressed and chunk-compressed bundles can be read directly from disk.

This is the fastest way to load an AssetBundle.

// Load asset bundles in the background whilst other tasks can be made.
