因此，我尝试创建一个自定义数据资产以在虚幻引擎中使用。我对此非常陌生，我主要关注艺术，所以尽管我对 OOP 有一个大致的了解，但 C++ 远不是我的强项。无论如何，我的课程如下所示：

USTRUCT()
struct FTrainFormations {

    GENERATED_USTRUCT_BODY()

    UPROPERTY(EditAnywhere)
    FString TrainEntry;

    UPROPERTY(EditAnywhere)
    bool Flipped;

    UPROPERTY(EditAnywhere)
    bool CargoLoaded;

    UPROPERTY(EditAnywhere)
    bool AllowSubstitution;

};

UCLASS(BluePrintType)
class TS2NEW_API UTrainFormation : public UDataAsset
{
    GENERATED_BODY()

public:
    UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Train")
    TArray<FTrainFormations> Formation;

    UPROPERTY(EditAnywhere, Category = "Train", DisplayName = "Train Numbering Overrides")
    TArray<int> TrainNumberingOverrides;

    UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Vehicle Substitution")
    float BlockTrainProbability;

    UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Rail Vehicle Information")
    int CommonnessWeighting;

    UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = "Rail Vehicle Information")
    bool IsSubstitutableUnit;

    UPROPERTY(EditAnywhere, BlueprintReadOnly, Category …
