虚幻引擎4：UShape组件给出错误"标识符未定义"。我能做什么？

Question

我正在使用虚幻4.18和Visual Studio 2017。使用某些类，如UShapeComponent，UBoxComponent，USphereComponent给出标识符是未定义的错误，而像USceneComponent，UStaticMeshComponent工作得很好。怎么了？

这是我的代码：

#pragma once
#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "MyActor.generated.h"
UCLASS()
class UNREALTUROIAL_API AMyActor : public AActor
{
GENERATED_BODY()
 public:    
// Sets default values for this actor's properties
AMyActor();
 protected:
// Called when the game starts or when spawned
virtual void BeginPlay() override;
 public:    
// Called every frame
virtual void Tick(float DeltaTime) override;

UPROPERTY(EditAnywhere)
    UStaticMeshComponent* PickUpMesh;
UPROPERTY(EditAnywhere)
    UShapeComponent* PickUpBox;
UPROPERTY(EditAnywhere)
    USceneComponent* PickUpRoot;


};

在此处输入代码您可以尝试将此包含添加到您的 .h 文件中
