在使用Unreal Engine 4（UE4）学习C++编程时，遇到代码错误，特别是涉及到UPROPERTY宏与蓝图交互时。发现当UPROPERTY包含BlueprintReadWrite或BlueprintReadOnly等参数时，必须将变量设为public或protected才能避免编译错误。通过调整变量访问权限，成功解决了问题并理解了其背后的原因。

在公司学习UE4下的C++代码编程时，依照《Unreal Engine4总动员》上的示例编写代码时，总是发生代码六的错误以及一些莫名其妙的错误。下图是书上示例：

这是我敲的代码：

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Damage") 
	int32 TotalDamage;
	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Damage")
	float DamageTimeInSecond;
	UPROPERTY(BlueprintReadOnly, VisibleAnywhere, Transient, Category = "Damage")
	float DamagePerSecond;
public:	
	// Sets default values for this actor's properties
	AFoat();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:	
	// Called every frame
	virtual void Ti
