先在UCLASS()前写入：

USTRUCT(BlueprintType)
struct FMyStruct	//必须以"F"开头
{
	GENERATED_BODY()	//必须添加“GENERATED_BODY()”
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "MyStruct1")
	int32 Health;
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "MyStruct2")
	FString Name;
};

【注意】这里实现了的Health、Name不同的Category名称

【注意】如果UPROPERTY不声明“BlueprintReadWrite, Category = “MyStruct1””，则Mystruct不能被中断，也不会显示属性引脚

然后在UCLASS()中写入：

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "MyStruct")
	FMyStruct MyStruct1;
