代码问题。


请问这段蓝图写成代码要如何写呢？

AMyActor::AMyActor(UTexture2D* PickUpTexture, class Actor* PickUpClass, FString PickUpName)
{
        // 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;

        PickUpTexture = PickUpTexture;
        PickUpClass =
        PickUpName = PickUpName;

        PickUpMesh = CreateDefaultSubobject<UStaticMeshComponent>(FName("PickUpMesh1"));

}

那两个PickUpTexture连起来，请问是赋值的意思还是==的意思呢？感谢。

AMyActor::AMyActor(UTexture2D* PickUpTexture, class Actor* PickUpClass, FString PickUpName)

这样的构造函数不允许

应该这样写
UCLASS()
class RMC_EXAMPLES_API ARuntimeMeshObjectBase : public AActor
{
        GENERATED_BODY()
       
public:       

        UPROPERTY(EditAnywhere)
        URuntimeMeshComponent* RuntimeMesh;
       
        // Sets default values for this actor's properties
        ARuntimeMeshObjectBase();

        // Called when the game starts or when spawned
        virtual void BeginPlay() override;
       
        // Called every frame
        virtual void Tick( float DeltaSeconds ) override;

};

ARuntimeMeshObjectBase::ARuntimeMeshObjectBase()
{
        // 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;


        RuntimeMesh = CreateDefaultSubobject<URuntimeMeshComponent>(TEXT("Runtime Mesh"));
        RootComponent = RuntimeMesh;
}

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

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

}

AMyActor::AMyActor(UTexture2D* PickUpTexture, class Actor* PickUpClass, FString PickUpName)

这样的 ...

是要按照这样写吗？ 我试过了，会报错，说不允许构造函数有参数

AMyActor::AMyActor(UTexture2D* PickUpTexture, class Actor* PickUpClass, FString PickUpName)

这样的 ...

我明白了，我发了这个求助之后，我把它删掉了，然后我在构造函数中按照蓝图的意思，写成这样FBag PickUpTezture = PickUpTexture ,可以编译通过，但是生成引擎的时候会崩溃，请问是什么原因呢？

回到家里电脑才看到您写的代码。。手机上看不到代码好奇怪的。。谢谢哈
