[UE5] refactor : 콜백 람다함수로 교체, 델리게이트 통합

1. 문제점 : 

본질적으로 float변수인데, 함수가 여러개일필요없다.

//기존코드
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnHealthChangedSignature, float, NewHealth);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnMaxHealthChangedSignature, float, NewMaxHealth);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnManaChangedSignature, float, NewMana);
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnMaxManaChangedSignature, float, NewMaxMana);

* 리팩토링후

DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnAttributeChangedSignature, float, NewValue);

	//BP에서 할당할거임
	UPROPERTY(BlueprintAssignable, Category="GAS|Attributes")
	FOnAttributeChangedSignature OnHealthChanged;

	UPROPERTY(BlueprintAssignable, Category="GAS|Attributes")
	FOnAttributeChangedSignature OnMaxHealthChanged;

	UPROPERTY(BlueprintAssignable, Category="GAS|Attributes")
	FOnAttributeChangedSignature OnManaChanged;

	UPROPERTY(BlueprintAssignable, Category="GAS|Attributes")
	FOnAttributeChangedSignature OnMaxManaChanged;

Delegate(속성).add(함수)

//속성이 바뀌면 함수실행

	AbilitySystemComponent->GetGameplayAttributeValueChangeDelegate(AuraAttributeSet->GetHealthAttribute()).AddLambda(
		[this](const FOnAttributeChangeData& Data)
		{
			OnHealthChanged.Broadcast(Data.NewValue);
		}
	);
	
	AbilitySystemComponent->GetGameplayAttributeValueChangeDelegate(AuraAttributeSet->GetMaxHealthAttribute()).AddLambda(
		[this](const FOnAttributeChangeData& Data)
		{
			OnMaxHealthChanged.Broadcast(Data.NewValue);
		}
	);

	AbilitySystemComponent->GetGameplayAttributeValueChangeDelegate(AuraAttributeSet->GetManaAttribute()).AddLambda(
		[this](const FOnAttributeChangeData& Data)
		{
			OnManaChanged.Broadcast(Data.NewValue);
		}
	);
	
	AbilitySystemComponent->GetGameplayAttributeValueChangeDelegate(AuraAttributeSet->GetMaxManaAttribute()).AddLambda(
		[this](const FOnAttributeChangeData& Data)
		{
			OnMaxManaChanged.Broadcast(Data.NewValue);
		}
	);

 

2. WBP_HealthGlob BP에러

원인 : 델리게이트가 바꼇음

해결 : 그냥 노드 끊었다가 재연결 해주면됨
