本文用于记录虚幻学习。

定义与UENUM类似，在UCLASS上方；但需要插入GENERATED_BODY()。

USTRUCT(BlueprintType) struct FCharacterData { GENERATED_BODY() public: UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Character") FString CharacterName = TEXT("DefaultName"); UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Character") int32 Health = 100; UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Character") float MoveSpeed = 600.0f; };

BlueprintType允许蓝图将这个结构体作为一种变量类型使用。编译后，蓝图即可创建ChacterData类型的变量。

在USTURCT中也可以创建成员函数，但不允许使用UFUNCTION。

定义完结构体变量，即可在头文件和源文件中使用。

//.h UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Character") FCharacterData CharacterData; //.cpp CharacterData.Name = TEXT("Knight"); CharacterData.Health = 200; CharacterData.MoveSpeed = 800.0f;
