CStatusComponent 생성

함수 생성

• void PlayDeadMode();

 

 

 

CMontageComponent.cpp

#include "Components/CMontagesComponent.h"
#include "Global.h"
#include "GameFramework/Character.h"

//#define LOG_UCMontagesComponent 1

UCMontagesComponent::UCMontagesComponent()
{
}

void UCMontagesComponent::BeginPlay()
{
	Super::BeginPlay();

	if(DataTable == nullptr)//DataTable이 없다면
	{   //DataTable이 없다고 메시지를 띄워준다.
		GLog->Log(ELogVerbosity::Error, "DataTable is not selected");

		return;
	}

	OwnerCharacter = Cast<ACharacter>(GetOwner());

	TArray<FMontageData*> datas;
	DataTable->GetAllRows<FMontageData>("", datas);//전체 데이터를 가져온다.

	//가져온 데이터를 배열에 넣어준다.
	for (int32 i = 0; i< (int32)EStateType::Max; i++)
	{
		for(FMontageData* data : datas)
		{
			if((EStateType)i == data->Type)
			{
				Datas[i] = data;

				continue;
			}
		}//for(data)
	}//for(i)
}


#if LOG_UCMontagesComponent
for (FMontagesData* data : datas)
{
	if (data == nullptr)
		continue;

	FString str;
	//Static이 붙는 애들은 Reflection(자료형의 타입을 변수로 다룰 수 있게 해준다).
	str.Append(StaticEnum<EStateType>()->GetValueAsString(data->Type));//Enum을 문자열로 바꾸어서 자료형의 이름을 가져온다.
	str.Append(" / ");
	str.Append(data->Montage->GetPathName());

	CLog::Log(str);
}
#endif


void UCMontagesComponent::PlayBackStepMode()
{
	PlayAnimMontage(EStateType::BackStep);
}

void UCMontagesComponent::PlayDeadMode()
{
	PlayAnimMontage(EStateType::Dead);
}

void UCMontagesComponent::PlayAnimMontage(EStateType InType)
{
	CheckNull(OwnerCharacter);

	FMontageData* data = Datas[(int32)InType];

	if(data == nullptr || data->Montage == nullptr)
	{
		GLog->Log(ELogVerbosity::Error, "None montages data");

		return;
	}

	OwnerCharacter->PlayAnimMontage(data->Montage, data->PlayRate);//data의 몽타주를 PlayRate속도로 OwnerCharacter에 적용하여 재생.
}

함수 정의

• void UCMontagesComponent::PlayDeadMode()  { PlayAnimMontage(EStateType::Dead); }
  • EStateType을 Dead로 만들어준다.

CAnimNotify_EndState

 

CAnimNotify_EndState.h

#pragma once

#include "CoreMinimal.h"
#include "Animation/AnimNotifies/AnimNotify.h"
#include "Components/CStateComponent.h"
#include "CAnimNotify_EndState.generated.h"

UCLASS()
class U2212_06_API UCAnimNotify_EndState : public UAnimNotify
{
	GENERATED_BODY()

private:
	UPROPERTY(EditAnywhere, Category = "Type")
		EStateType StateType;

public:
	FString GetNotifyName_Implementation() const override;

	void Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation) override;
};

변경사항 없음.

 

 

CAnimNotify_EndState.cpp

#include "CAnimNotify_EndState.h"
#include "Global.h"
#include "Characters/ICharacter.h"

FString UCAnimNotify_EndState::GetNotifyName_Implementation() const
{
	return "EndState";
}

void UCAnimNotify_EndState::Notify(USkeletalMeshComponent* MeshComp, UAnimSequenceBase* Animation)
{
	Super::Notify(MeshComp, Animation);
	CheckNull(MeshComp);
	CheckNull(MeshComp->GetOwner());

	IICharacter* character = Cast<IICharacter>(MeshComp->GetOwner());
	CheckNull(character);

	switch(StateType)
	{
		case EStateType::BackStep: character->End_BackStep(); break;
		case EStateType::Hitted: character->End_Hitted(); break;
		case EStateType::Dead: character->End_Dead(); break;
	}
}

EndState::Notify에 EStateType을 추가한다.

• switch(StateType) {
  case EStateType::BackStep: character->End_BackStep(); break;
  case EStateType::Hitted: character->End_Hitted(); break;
  case EStateType::Dead: character->End_Dead(); break;
  }
