Addressables samples

The Addressables package contains samples that you can download into your project. To access the samples go to Window > Package Manager > Addressables.

These samples include examples on how to disable asset importing during a build, creating custom build and Play mode scripts, and providing an AddressableUtility class.

When you download and import a sample, it's placed inside the Assets/Samples/Addressables/{AddressablesVersionNumber} path of your project.

Sample	Description
Addressables Utility	Contains a set of utility functions for Addressables. The script contains a static method GetAddressFromAssetReference which provides the Addressable address used to reference a given AssetRefence internally.
ComponentReference	Creates an AssetReference that's restricted to having a specific component. For more information see the ComponentReference sample project located in the Addressables Samples repository.
Custom Build and Playmode Scripts	Includes two custom scripts: - A custom Play mode script located in Editor/CustomPlayModeScript.cs of the sample. This script works similarly to the Use Existing Build (requires built groups) play mode script already included. The methods added to accomplish this are CreateCurrentSceneOnlyBuildSetup and RevertCurrentSceneSetup on the CustomBuildScript. - A custom build script located in Editor/CustomBuildScript.cs of the sample. This custom build script creates a build that only includes the currently open scene. A bootstrap scene is automatically created and a script is added that loads the built scene on startup. For these examples, the build and load paths used by default are [UnityEngine.AddressableAssets.Addressables.BuildPath]/[BuildTarget] and {UnityEngine.AddressableAssets.Addressables.RuntimePath}/[BuildTarget] respectively. The ScriptableObject of the class has already been created, but you can use the Create menu to make another ScriptableObject. For this CustomPlayModeScript the create menu path is Addressables > Content Builders > Use CustomPlayMode Script. By default, this creates a CustomPlayMode.asset ScriptableObject. The same goes for the CustomBuildScript.
Disable Asset Import on Build	Provides a script that disables asset importing during a player build. This improves build performance because AssetBundles are copied into StreamingAssets at build time. This sample is only relevant for Editor versions below 2021.2. In 2021.2+, the Editor provides the ability to include folders outside of Assets/ into StreamingAssets. When the sample is imported into the project, a player build without asset importing can be triggered by the new menu item Build/Disabled Importer Build. The build output is placed into DisabledImporterBuildPath/{EditorUserBuildSettings.activeBuildTarget}/ by default. The sample class DisableAssetImportOnBuild can be edited to alter the build path.
Import Existing Group	Contains a tool that imports group assets, for example from a custom package, to the current project. The tool is located under Window/Asset Management/Addressables/Import Groups. The window requires a path to the AddressableAssetGroup.asset scriptable object, a name for the group, and a folder for any schemas related to the imported AddressableAssetGroup.
Prefab Spawner	Provides a basic script that instantiates and destroys a prefab AssetReference. To use the sample, attach the provided script, PrefabSpawnerSample, to a GameObject in your scene. Assign an AdressableAsset to the AssetReference field of that script. If you're using the Use Existing Build playmode script, ensure that your Addressable content is built. Then, enter Play mode.
Custom Analyze Rules	This sample shows how to create custom AnalyzeRules for use within the Analyze window. Both rules follow the recommended pattern for adding themselves to the UI.
