BuildAssetBundleOptions.DisableLoadAssetByFileName

Description

Disables Asset Bundle LoadAsset by file name.

Asset Bundles by default have three ways to look up the same asset: full asset path, asset file name, and asset file name with extension. The full path is serialized into Asset Bundles, while file name and file name with extension are generated when an Asset Bundle is loaded from file.

Example: "Assets/Prefabs/Player.prefab", "Player", and "Player.prefab"

This option will set a flag on Asset Bundles to prevent creating the asset file name lookup. This option saves runtime memory and loading performance for asset bundles.

//Create a folder (right click in the Assets folder and go to Create>Folder), and name it “Editor” if it doesn’t already exist
//Place this script in the Editor folder

//This script creates a new Menu named “Build Asset” and new options within the menu named “Normal” and “Disable Load Asset By filename”. Click these menu items to build an AssetBundle into a folder.

        //Create a folder to put the Asset Bundle in.
        // This puts the bundles in your custom folder (this case it's "MyAssetBuilds") within the Assets folder.
        //Build AssetBundles with no special options
        BuildPipeline.BuildAssetBundles("Assets/MyAssetBuilds", BuildAssetBundleOptions.None, BuildTarget.StandaloneOSX);
    }

    //Creates a new item (Disable Load Asset By Name) in the new Build Asset Bundles menu
