[UE5] 위젯에 실제 데이터 바인딩 구현1, cpp에서 태그추가-조회

1. GETag 저장용 클래스생성(싱글톤)

싱글톤만드는법 : static getter, setter 만듬

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "CoreMinimal.h"
#include "GameplayTagContainer.h"

/**
 * AuraGameplayTags
 *
 * 싱글톤, 포함하는 native GETags
 */

struct FAuraGameplayTags
{
public:
 static const FAuraGameplayTags& Get(){ return GameplayTags; }
 static void InitializeNativeGameplayTags(); //@Setter
 
protected:

private:
 static FAuraGameplayTags GameplayTags;
};

// Fill out your copyright notice in the Description page of Project Settings.


#include "AuraGameplayTags.h"
#include "GameplayTagsManager.h"

FAuraGameplayTags FAuraGameplayTags::GameplayTags; //전역변수

void FAuraGameplayTags::InitializeNativeGameplayTags()
{
    //단순히 태그를 추가
    UGameplayTagsManager::Get().AddNativeGameplayTag(FName("Attributes.Secondary.Armor"),FString("Reduces damage taken, improves Block Chance"));
}

프로젝트세팅에서 태그추가하는 작업이랑 똑같음!

결과

 

* 커스텀 에셋매니저 만들기

// Fill out your copyright notice in the Description page of Project Settings.

#pragma once

#include "CoreMinimal.h"
#include "Engine/AssetManager.h"
#include "AuraAssetManager.generated.h"

/**
 * 
 */
UCLASS()
class AURA_API UAuraAssetManager : public UAssetManager
{
    GENERATED_BODY()

public:
    const UAuraAssetManager& Get();

protected:
    virtual void StartInitialLoading() override;
};

// Fill out your copyright notice in the Description page of Project Settings.


#include "AuraAssetManager.h"
#include "AuraGameplayTags.h"

const UAuraAssetManager& UAuraAssetManager::Get()
{
    check(GEngine);
    UAuraAssetManager* AuraAssetManager = Cast<UAuraAssetManager>(GEngine->AssetManager);
    return *AuraAssetManager; 
}

void UAuraAssetManager::StartInitialLoading() //게임 에셋들 초기세팅하는 함수
{
    Super::StartInitialLoading();
    //Tag들 추가 하기 최적의 장소!
    FAuraGameplayTags::InitializeNativeGameplayTags();

    //할일 : AuraAssetManager를 AssetManager로 설정
}

* 에셋매니저를 커스텀으로 설정

 

* cpp native tag를 만드는 방법은 알겠는데, 이미 만든속성을 cpp native로 만드는방법은?

1. DT지우고 다시 설정하면됨 ㅋㅋ

 

* cpp에서 GETag는 어떻게 사용?

1. 일단 특정 태그를 Tag변수에 저장해둠

struct FAuraGameplayTags
{
public:
 static const FAuraGameplayTags& Get(){ return GameplayTags; }
 static void InitializeNativeGameplayTags(); //@Setter

 FGameplayTag Attributes_Secondary_Armor;

FAuraGameplayTags FAuraGameplayTags::GameplayTags; //전역변수

void FAuraGameplayTags::InitializeNativeGameplayTags()
{
    //단순히 태그를 추가
    GameplayTags.Attributes_Secondary_Armor = UGameplayTagsManager::Get().AddNativeGameplayTag(FName("Attributes.Secondary.Armor"),FString("Reduces damage taken, improves Block Chance"));
}

2. Test위치를 설정하고, Get한다음, 디버그찍어봄

void UAuraAbilitySystemComponent::AbilityActorInfoSet()
{
    OnGameplayEffectAppliedDelegateToSelf.AddUObject(this,&UAuraAbilitySystemComponent::EffectApplied);

    const FAuraGameplayTags& GameplayTags= FAuraGameplayTags::Get();
    //GameplayTags.Attributes_Secondary_Armor.ToString();
    GEngine->AddOnScreenDebugMessage(
       -1,10.f,FColor::Orange,FString::Printf(TEXT("Tag : %s"),*GameplayTags.Attributes_Secondary_Armor.ToString()))
}

cpp에서 태그에 접근가능함이 확인되었다!

cpp에서 각 태그변수만들고, 저장하면 되겠다.

    GameplayTags.Attributes_Secondary_MaxMana = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("Attributes.Secondary.MaxMana"),
       FString("Maximum amount of Mana obtainable")
       );
}

실제로 에디터에 태그 추가 노가다 && 변수에 넣기

 

결과

추가로 BP에서도 사용가능하다.
