对属性集中的属性需要做到的固定宏-ATTRIBUTE_ACCESSORS

1 对属性集中的属性，在值变化时的回调

example：

UFUNCTION()
void OnRep_Health(const FGameplayAttributeData& OldHealth) const;

void UAuraAttributeSet::OnRep_Health(const FGameplayAttributeData& OldHealth) const
{
    GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet,Health,OldHealth);
}

 

 

2 Set Get Init  |   可以快速的实现这些定义和声明

#define ATTRIBUTE_ACCESSORS(ClassName, PropertyName) \
    GAMEPLAYATTRIBUTE_PROPERTY_GETTER(ClassName, PropertyName) \
    GAMEPLAYATTRIBUTE_VALUE_GETTER(PropertyName) \
    GAMEPLAYATTRIBUTE_VALUE_SETTER(PropertyName) \
    GAMEPLAYATTRIBUTE_VALUE_INITTER(PropertyName)

example：

UPROPERTY(BlueprintReadOnly,ReplicatedUsing = OnRep_Health,Category = "vital Attributes")
FGameplayAttributeData Mana;
ATTRIBUTE_ACCESSORS(UAuraAttributeSet,Mana);
