[UE5] 태그-입력 연결 구현, 런타임에 입력변경 구현준비

인풋 방법 비교

*구현

1. Data Asset 만들기

#pragma once

#include "CoreMinimal.h"
#include "Engine/DataAsset.h"
#include "AuraInputConfig.generated.h"

/**
 * 
 */
UCLASS()
class AURA_API UAuraInputConfig : public UDataAsset
{
    GENERATED_BODY()
    
};

 

2. 설계

구조체 : InputAction, Tag

변수 : 구조체( InputAction, Tag )배열을 가짐

함수 : 태그에 맞는 InputAction 찾는 함수

#pragma once

#include "CoreMinimal.h"
#include "GameplayTagContainer.h"
#include "Engine/DataAsset.h"
#include "AuraInputConfig.generated.h"


USTRUCT(BlueprintType)
struct FAuraInputAction
{
    GENERATED_BODY()

    UPROPERTY(EditDefaultsOnly)
    const class UInputAction* InputAction = nullptr;

    UPROPERTY(EditDefaultsOnly)
    FGameplayTag InputTag = FGameplayTag(); //포인터아님 -> 헤더인클루드해야함
};

/**
 * 
 */
UCLASS()
class AURA_API UAuraInputConfig : public UDataAsset
{
    GENERATED_BODY()
public:

    const UInputAction* FindAbilityInputActionForTag(const FGameplayTag& InputTag, bool bLogNotFound=false) const;
    
    UPROPERTY(EditDefaultsOnly,BlueprintReadOnly)
    TArray<FAuraInputAction> AbilityInputActions;
    
};

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


#include "Input/AuraInputConfig.h"

const UInputAction* UAuraInputConfig::FindAbilityInputActionForTag(const FGameplayTag& InputTag,bool bLogNotFound) const
{
    for(const FAuraInputAction& Action :AbilityInputActions)
    {
       if(Action.InputAction && Action.InputTag==InputTag) //nullchk, 일치하는 태그발견시
       {
          return Action.InputAction; //그때 인풋액션 리턴
       }
    }
    if(bLogNotFound)
    {
       UE_LOG(LogTemp,Error,TEXT("Can`t find AbilityInputAction for Input Tag [%s], on InputConfig [%s]"),*InputTag.ToString(),*GetNameSafe(this))
       //그때 태그, 클래스이름 출력
    }
    return nullptr;
}

 

* Tags.cpp에서 태그도 추가해줘야함(변수추가, 에디터에 태그추가 함수에 추가)

struct FAuraGameplayTags
{
public:
    ...

    FGameplayTag InputTag_LMB;
    FGameplayTag InputTag_RMB;
    FGameplayTag InputTag_1;
    FGameplayTag InputTag_2;
    FGameplayTag InputTag_3;
    FGameplayTag InputTag_4;

void FAuraGameplayTags::InitializeNativeGameplayTags()
{
     ...

    /*
     * Input Tags
     */
    GameplayTags.InputTag_LMB = UGameplayTagsManager::Get().AddNativeGameplayTag(
    FName("InputTag.LMB"),
    FString("Input Tag for Left Mouse Button")
    );

    GameplayTags.InputTag_RMB = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("InputTag.RMB"),
       FString("Input Tag for Right Mouse Button")
       );

    GameplayTags.InputTag_1 = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("InputTag.1"),
       FString("Input Tag for 1 key")
       );

    GameplayTags.InputTag_2 = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("InputTag.2"),
       FString("Input Tag for 2 key")
       );

    GameplayTags.InputTag_3 = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("InputTag.3"),
       FString("Input Tag for 3 key")
       );

    GameplayTags.InputTag_4 = UGameplayTagsManager::Get().AddNativeGameplayTag(
       FName("InputTag.4"),
       FString("Input Tag for 4 key")
       );
}

결과 : 인풋태그 정상추가

 

* BP작업

1. BP에서 DataAsset추가

2. IA 추가

이동은2차원 but 능력입력은 1차원 -> Axis1D로 만듬

전부 추가함

 

3. IMC에 IA들 추가, 설정

전부설정함

 

4. DA에서 태그와 IA 연결!

전부 입력완

런타임에 얼마든지 다른 입력으로 교체가능!!
