Class AssetReference

Reference to an addressable asset. This can be used in script to provide fields that can be easily set in the editor and loaded dynamically at runtime. To determine if the reference is set, use RuntimeKeyIsValid().

Inheritance

System.Object

AssetReference

AssetReferenceT<TObject>

Namespace: UnityEngine.AddressableAssets

Syntax

[Serializable]
public class AssetReference : IKeyEvaluator

Constructors

AssetReference()

Construct a new AssetReference object.

Declaration

public AssetReference()

AssetReference(String)

Construct a new AssetReference object.

Declaration

public AssetReference(string guid)

Parameters

Type	Name	Description
System.String	guid	The guid of the asset.

Properties

Asset

The loaded asset. This value is only set after the AsyncOperationHandle returned from LoadAssetAsync completes. It will not be set if only InstantiateAsync is called. It will be set to null if release is called.

Declaration

public object Asset { get; }

Property Value

Type	Description
System.Object

RuntimeKey

The actual key used to request the asset at runtime. RuntimeKeyIsValid() can be used to determine if this reference was set.

Declaration

public object RuntimeKey { get; }

Property Value

Type	Description
System.Object

Implements

IKeyEvaluator.RuntimeKey
