将 Unreal Engine 4.24.2 与 VS2019 或 VSCode 一起使用时，如何修复这些错误的 Intellisense 错误？

Question

我正在关注Unreal Programming Quick Start guide

我复制并粘贴了指南底部的代码示例。我试过同时使用 VS2019 和 VSCode，都给我同样的错误：

UStaticMeshComponent *AFloatingActor::VisualMesh
pointer to incomplete class type is not allowed

static <error-type> UStaticMesh
name followed by '::' must be a class or namespace name

还有更多...

当我在虚幻引擎中编译时，它编译时出现 0 个错误并按预期工作。

有没有办法修复这些错误错误并继续使用 Intellisense / 获取代码完成？

我真的只是希望能够看到我正在使用的组件的成员函数和定义，因为我是 Unreal 的新手。

这是指南中的代码，我在这个演示项目的源代码中有它：

FloatingActor.h

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

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

UCLASS()
class CPPTUTORIAL_API AFloatingActor : public AActor
{
    UPROPERTY(VisibleAnywhere)
        UStaticMeshComponent* VisualMesh;
    GENERATED_BODY()



public: 
    // Sets default values for this actor's properties
    AFloatingActor();

    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "FloatingActor")
        float FloatHeight = 20.0f;

    UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "FloatingActor")
        float RotationSpeed = 20.0f;

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 * FloatHeight;       //Scale our height by a factor of 20
    float DeltaRotation = DeltaTime * RotationSpeed;    //Rotate by 20 degrees per second
    NewRotation.Yaw += DeltaRotation;
    SetActorLocationAndRotation(NewLocation, NewRotation);
}

这个错误是由于在 c_cpp_properties.json 中没有定义导致的 在 c_cpp_properties.json 的 "defines": [] 之间添加此代码
