오늘은 아레나 배틀 마지막 챕터이다 마지막으로는 일시정지 기능과 게임 클리어 화면을 만들도록 하겠다
오늘 사용한 에셋은 링크에서 다운로드 가능하다
일시정지 화면 구현
먼저 다운로드 받은 에셋을 UI폴더에 넣고, 일시정지를 위한 버튼을 매핑하도록 한다
나의 경우에는 Pause에 P 키를 이용하였다
일시정지는 폰에 관계없이 입력을 받아야하기에, 플레이어 컨트롤러에 구현해주었다
ABPlayerController.h
UCLASS()
class ARENABATTLE_API AABPlayerController : public APlayerController
{
...
protected:
virtual void BeginPlay() override;
virtual void SetupInputComponent() override;
...
private:
void OnGamePause();ABPlayerController.cpp
...
void AABPlayerController::SetupInputComponent()
{
Super::SetupInputComponent();
InputComponent->BindAction(TEXT("GamePause"), EInputEvent::IE_Pressed, this, &AABPlayerController::OnGamePause);
}
...다음은 UI가 사용할 클래스를 UserWidget을 부모로 만들어준다
생성했다면, UI의 부모 클래스를 생성한 위젯으로 설정한다
플레이어 컨트롤러에 버튼을 눌렀을 경우 UI와 마우스가 나타나며 UI만 조작이 가능하도록 설정하는 함수를 만들어준다

이제 UI에 기능들을 구현해준다

ABPlayerController->RestartLevel();
}클리어 화면 구현
다음은 클리어화면을 구현할 것이다 클리어 화면은 방금 만든 ABGameplayWidget 을 상속하는 클래스로 생성한다
먼저 UI에서 부모 클래스로 생성한 ABGameplayResultWidget을 지정해주고
게임의 클리어 여부는 게임의 정보이므로 게임 스테이트 클래스를 수정한다
ABGameState.h
public:
AABGameState();
void SetGameCleared();
bool IsGameCleared() const;
...
private:
...
UPROPERTY(Transient)
bool bGameCleared;
};ABGameState.cpp
AABGameState::AABGameState()
{
TotalGameScore = 0;
bGameCleared = false;
}
...
void AABGameState::SetGameCleared()
{
bGameCleared = true;
}
bool AABGameState::IsGameCleared() const
{
return bGameCleared;
}다음은 게임의 클리어 여부를 판단하는 작업을 하기 위해 게임모드에서 클리어가 되면 모든 작업을 멈추고 UI를 생성하도록 한다
ABGameMode.h
...
private:
UPROPERTY()
int32 ScoreToClear;ABGameMode.cpp
// Fill out your copyright notice in the Description page of Project Settings.
#include "ABGameMode.h"
#include "ABCharacter.h"
#include "ABPlayerController.h"
#include "ABPlayerState.h"
#include "ABGameState.h"
AABGameMode::AABGameMode()
{
...
ScoreToClear = 2;
}
...
void AABGameMode::AddScore(AABPlayerController* ScoredPlayer)
{
...
if (GetScore() >= ScoreToClear)
{
ABGameState->SetGameCleared();
for (FConstPawnIterator It = GetWorld()->GetPawnIterator(); It; ++It)
(*It)->TurnOff();
for (FConstPlayerControllerIterator It = GetWorld()->GetPlayerControllerIterator(); It; ++It)
{
const auto ABPlayerController = Cast<AABPlayerController>(It->Get());
if (nullptr != ABPlayerController)
ABPlayerController->ShowResultUI();
}
}
}
int32 AABGameMode::GetScore() const
{
return ABGameState->GetTotalGameScore();
}
캐릭터가 죽었을 경우에도 종료화면이 나와야한다 다만 이때는 클리어상태가 아닌 실패화면으로 나올 것이다
ABCharacer.cpp
case ECharacterState::DEAD:
{
...
GetWorld()->GetTimerManager().SetTimer(DeadTimerHandle, FTimerDelegate::CreateLambda([this]() ->void
{
if (bIsPlayer)
ABPlayerController->ShowResultUI();
else
Destroy();
}), DeadTimer, false);
break;
}이제 실제 결과가 나타날 클래스를 입력한다

};ABGameplayResultWidget.cpp
// Fill out your copyright notice in the Description page of Project Settings.
#include "ABGameplayResultWidget.h"
#include "Components/TextBlock.h"
#include "ABGameState.h"
void UABGameplayResultWidget::BindGameState(AABGameState* GameState)
{
CurrentGameState = GameState;
}
void UABGameplayResultWidget::NativeConstruct()
{
Super::NativeConstruct();
auto Result = Cast<UTextBlock>(GetWidgetFromName(TEXT("txtResult")));
Result->SetText(FText::FromString(CurrentGameState->IsGameCleared() ? TEXT("Mission Complete") : TEXT("Mission Failed")));
auto TotalScore = Cast<UTextBlock>(GetWidgetFromName(TEXT("txtTotalScore")));
TotalScore->SetText(FText::FromString(FString::FromInt(CurrentGameState->GetTotalGameScore())));
}마지막으로 플레이어 컨트롤러에 바인딩하는 작업을 해준다
ABPlayerController.cpp
void AABPlayerController::ShowResultUI()
{
auto ABGameState = Cast<AABGameState>(UGameplayStatics::GetGameState(this));
ResultWidget->BindGameState(ABGameState);
ResultWidget->AddToViewport();
ChangeInputMode(false);
}마지막으로 잘 작동하는지 확인하도록 한다
