связанная информация:

C ++ понимает проблему динамической загрузки: LoadClass <T> () и LoadObject <T> ()

http://aigo.iteye.com/blog/2281558
C ++ реализует динамическую загрузку UObject: StaticLoadObject (); взять в качестве примеров текстуру и материал

http://aigo.iteye.com/blog/2268056

Упомянутая здесь статическая загрузка относится к методу загрузки, который должен быть завершен в конструкторе. Значение динамической загрузки может быть загружено во время выполнения. В исходном коде UE4 первый фактически является слоем инкапсуляции для второго, а именноFObjectFinder () является инкапсуляцией LoadObject ()。But，FClassFinder () не является инкапсуляцией LoadClass ()，FClassFinder () внутренне вызывает LoadObject ().

Если вы хотите получить класс типа чертежа БП, вы можете получить его через ConstructorHelpers :: FClassFinder (), например:

static ConstructorHelpers::FClassFinder<AActor> UnitSelector(TEXT("Blueprint'/Game/MyProject/MyBlueprint.MyBlueprint'"));
TSubclassOf<AActor> UnitSelectorClass = UnitSelector.Class;

 
Но при запуске игры сообщается об ошибке, что файл не может быть найден, например:

Default property warnings and errors:

Error: COD Constructor (MyGameMode): Failed to find /Game/MyProject/MyBlueprint.MyBlueprint

Есть два решения (это яма UE4, он меня долго тратит …):

А, вcopy referenceДобавить после пути к файлу_C,Например:Blueprint’/Game/Blueprints/MyBlueprint.MyBlueprint_C‘

static ConstructorHelpers::FClassFinder<AActor> UnitSelector(TEXT("Blueprint'/Game/Blueprints/MyBlueprint.MyBlueprint_C'"));
TSubclassOf<AActor> UnitSelectorClass = UnitSelector.Class;

B, удалите префикс пути:/Game/Blueprints/MyBlueprint

static ConstructorHelpers::FClassFinder<AActor> UnitSelector(TEXT("/Game/Blueprints/MyBlueprint"));
TSubclassOf<AActor> UnitSelectorClass = UnitSelector.Class;

Также обратите внимание: имя шаблона FClassFinder <T>,Невозможно написать UBlueprint напрямую,Например:FClassFinder<UBlueprint> Это неправильно.Какой родительский класс выбран при создании проекта, напишите имя соответствующего родительского класса, Если это Актёр, то это должно быть записано как:FClassFinder<AActor>, иначе он не может быть успешно загружен.

При использовании TSubclassOf <T>Название шаблона должно быть таким же

К тому же,Имя шаблона в функции FClassFinder <T> () должно совпадать с именем шаблона переменной TSubclassOf <T>.Например, вышеупомянутые все AActors, если они не совпадают, вышеупомянутая ошибка также произойдет.
Приведите другой пример:

static ConstructorHelpers::FClassFinder<UUserWidget> TestBP(TEXT("/Game/Blueprints/MyWidget_BP"));
TSubclassOf<UUserWidget> MyWidgetClass = TestBP.Class;

Вы также можете использовать UClass * для замены TSubclassOf <T>

Например:

static ConstructorHelpers::FClassFinder<UUserWidget> TestBP(TEXT("/Game/Blueprints/MyWidget_BP"));
UClass* MyWidgetClass = TestBP.Class;

Я видел много примеров черезFObjectFinder()Чтобы получить этот класс, сейчас думать об этом беспомощно. Документация по UE4 довольно скудна. Не только документация проекта не обновляется синхронно, но и документация C ++ жалкая.

static ConstructorHelpers::FObjectFinder<UBlueprint> UnitSelector(TEXT("Blueprint'/Game/MyProject/MyBlueprint.MyBlueprint'"));
TSubclassOf<AActor> UnitSelectorClass = (UClass*)UnitSelector.Object->GeneratedClass;

In the player class constructor, I use ConstructorHelpers::FObjectFinder to get a link to blueprint animation class:

static ConstructorHelpers::FObjectFinder<UAnimBlueprint> finderAnim(TEXT("AnimBlueprint'/Game/MixamoAnimPack/Mixamo_Adam/Anims/MixamoAnimBP_Adam.MixamoAnimBP_Adam'"));

Then I call SetAnimClass() method:

if (finderAnim.Succeeded())
    PlayerMesh->SetAnimClass(finderAnim.Object->GetAnimBlueprintGeneratedClass());

Everything works in the UE4 editor, but when I started packing the project, something went wrong and I got an error:

> PackagingResults: Warning: Error: CDO Constructor (Enemy): Failed to find /Game/MixamoAnimPack/Mixamo_Mortimer/Anims/MixamoAnimBP_Mortimer.MixamoAnimBP_Mortimer

Is there a solution to this problem or I should create a blueprint class of the player and choose the animation there?

Here is a similar question on Unreal Engine’s Forum.

This is the proposed solution:

Adding «_C» at the end of filename and treating the file as a «UClass»
makes things run smoother. Now it runs properly on both editor and
packaged game.

So your initialization of finderAnim will look like:

static ConstructorHelpers::FObjectFinder<UClass> finderAnim(TEXT("AnimBlueprint'/Game/MixamoAnimPack/Mixamo_Adam/Anims/MixamoAnimBP_Adam.MixamoAnimBP_Adam_C'"));

PS: Go through JamesG’s (Lead Programmer — UE4 Animation/Physics/Audio Team) answer on this thread to understand it more clearly.

Another possibly more robust solution is to use FClassFinder.

static ConstructorHelpers::FClassFinder<UAnimInstance> finderAnim(TEXT("/Game/MixamoAnimPack/Mixamo_Adam/Anims/MixamoAnimBP_Adam"));

after which you can simply

PlayerMesh->SetAnimClass(finderAnim.Class);
