首先建立一個繼承自UObject類的類，起名為UserAsset。

16 UCLASS()
17 class MYPROJECT14_API UUserAsset : public UObject
18 {
19     GENERATED_BODY()
20 
21 public:
22     UUserAsset();

27 
28     UPROPERTY(EditAnywhere, Category = Properties)
29     FString Name;
 
30 };
31

34 //以下是原始檔
35 #include "UserAsset.h"
36 
37 UUserAsset::UUserAsset() {
38     Name = "Dlak";
39 }

在建立一個Factory類，自定義的資源建立都是需要通過Factory類實現的。

 5 #include "CoreMinimal.h"
 6 #include "Factories/Factory.h"
 7 #include "UserAsset.h"
 8     /*

11 */
12 #include "MyAssetFactory.generated.h"
13 
14 /**
15  * 
16  */
17 UCLASS()
18 class MYPROJECT14_API UMyAssetFactory : public UFactory
19 {
20     GENERATED_BODY()
21 
22 public:
23     UMyAssetFactory();
24     /*
25 版權所有：虎牙維護世界和平
26 部落格園地址：https://www.cnblogs.com/dlak/
27 */
28     virtual UObject* FactoryCreateNew(UClass* InClass, UObject* InParent, FName InName, EObjectFlags Flags, UObject* Context, FFeedbackContext* Warn, FName CallingContext) override;
29 };

virtual UObject* FactoryCreateNew()是繼承自父類的方法，用於工廠建立新的資源用的方法。

 4 #include "MyAssetFactory.h"
 5 
 6 UMyAssetFactory::UMyAssetFactory():UFactory(){
 7     
 8     bCreateNew = true;
 9     bEditAfterNew = false;
10     SupportedClass = UUserAsset::StaticClass();//工廠需要建立的例項型別
11 }

16 
17 UObject* UMyAssetFactory::FactoryCreateNew(UClass* InClass, UObject* InParent, FName InName, EObjectFlags Flags, UObject* Context, FFeedbackContext* Warn, FName CallingContext)
18 {
19 
20     auto MyAsset = NewObject<UUserAsset>(InParent, InClass, InName, Flags); //因為Asset是繼承自UObject類的，所以這裡用的是NewObject
21 
22     return MyAsset;
23 }
