Create a custom asset pack

To create a custom asset pack, create a directory with a name that ends with .androidpack. You can place this directory anywhere in your project’s Assets directory, or any subdirectory.

Important: Unity doesn’t import assets from .androidpack directories, so you can’t use assets in custom asset packs directly in Unity scenes. To use assets from custom asset packs, you must manually access and load them dynamically at runtime. For information on how to do this, see Manage asset packs at runtime.

The following steps explain how to create a custom asset pack named MyAssets1:

1. アセットパックを作成したいディレクトリに移動します。これは、Assets に直接置いたり、Assets/CustomAssetPacks のようなサブディレクトリに置くこともできます。
2. Create a new directory and call it MyAssets1.androidpack. To add any assets to the asset pack, place them inside this folder.
   Note: Unity doesn’t include empty asset packs in builds. Also, asset pack names must begin with a letter and consist of English alphanumeric characters or an underscore.
3. By default, the delivery mode is on-demand, which means that if you don’t change the delivery mode, you need to manually download the asset pack at runtime. For information on how to do this, see Manage asset packs at runtime.
4. To use a different delivery mode, create a file called build.gradle inside the custom asset pack directory. Paste the following into the file:

apply plugin: 'com.android.asset-pack'
assetPack {
    packName = "MyAssets1"
    dynamicDelivery {
        deliveryType = "fast-follow"
    }
}

これにより、配信モードが fast-follow に設定され、Google Play がアプリケーションをインストールした後にアセットパックを自動的にダウンロードします。このファイルの形式については、アセット配信を統合する を参照してください。

Note: The packName you specify in the build.gradle file should match the asset pack directory name you set without the .androidpack extension.
