ue4 用c++创建的类无法试用

Question

问题描述

没有ue4的标签，就选择u3d了
ue版本：4.25.3
vs版本：2019 16.7.3

用c++ 类创建的Actor，无法在 ue4 中使用

代码来源为ue4 官网， 编程快速入门（链接地址）

以下为我自己的代码
FloatingActor.h

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "FloatingActor.generated.h"

UCLASS()
class TEST_API AFloatingActor : public AActor
{
    GENERATED_BODY()
    
public:    
    // Sets default values for this actor's properties
    AFloatingActor();
    UPROPERTY(VisibleAnywhere)
    UStaticMeshComponent* VisualMesh;

protected:
    // Called when the game starts or when spawned
    virtual void BeginPlay() override;

public:    
    // Called every frame
    virtual void Tick(float DeltaTime) override;

};

FloatingActor.cpp

#include "FloatingActor.h"

// Sets default values
AFloatingActor::AFloatingActor()
{
     // Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
    PrimaryActorTick.bCanEverTick = true;

    VisualMesh = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Mesh"));
    VisualMesh->SetupAttachment(RootComponent);

    static ConstructorHelpers::FObjectFinder<UStaticMesh> CubeVisualAsset(TEXT("/Game/StarterContent/Shapes/Shape_Cube.Shape_Cube"));

    if (CubeVisualAsset.Succeeded())
    {
        VisualMesh->SetStaticMesh(CubeVisualAsset.Object);
        VisualMesh->SetRelativeLocation(FVector(0.0f, 0.0f, 0.0f));
    }

}

// Called when the game starts or when spawned
void AFloatingActor::BeginPlay()
{
    Super::BeginPlay();
    
}

// Called every frame
void AFloatingActor::Tick(float DeltaTime)
{
    Super::Tick(DeltaTime);

    FVector NewLocation = GetActorLocation();
    FRotator NewRotation = GetActorRotation();
    float RunningTime = GetGameTimeSinceCreation();
    float DeltaHeight = (FMath::Sin(RunningTime + DeltaTime) - FMath::Sin(RunningTime));
    NewLocation.Z += DeltaHeight * 20.0f;       //Scale our height by a factor of 20
    float DeltaRotation = DeltaTime * 20.0f;    //Rotate by 20 degrees per second
    NewRotation.Yaw += DeltaRotation;
    SetActorLocationAndRotation(NewLocation, NewRotation);

}

编译后，将FloatingActor 拖拽入 透视视口，如图所示

在透视视口中什么都没有，但是在世界大纲视图中已经存在了。

请教我哪里做的不对吗？

新建项目时，应选择创建 c++ 项目。默认选择的是 蓝图项目

目前还不知道，蓝图 和 c++ 的方式能否共存。
