我一直在尝试显示我在C ++类中创建的一些变量,然后基于该类创建一个Blueprint类。但是,当我看到对象的详细信息或尝试在“蓝图”中找到此变量时,它们不会显示。

我基本上已经从UE4文档中复制并粘贴了代码,请参见此处:https://docs.unrealengine.com/en-us/Programming/Introduction,但是这些变量对我而言并不显示。

// MyActor.cpp

#include "MyActor.h"

// Sets default values
AMyActor::AMyActor()
{
    //PrimaryActorTick.bCanEverTick = true;
    TotalDamage = 200.0f;
} 

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

// Called every frame
void AMyActor::Tick(float DeltaTime)
{
    Super::Tick(DeltaTime);
}
// MyActor.h

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

UCLASS()
class MYPROJECT3_API AMyActor : public AActor
{
    GENERATED_BODY()

public: 
    UPROPERTY(EditAnywhere)
    float TotalDamage;
    // 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;
};

我想从事件图中修改此变量。请帮助我找出我做错了什么,如果您需要更多信息,我们将很乐意为您提供信息。

使用BlueprintReadWriteBlueprintReadOnly

UPROPERTY(EditAnywhere, BlueprintReadWrite)
float TotalDamage;
