* GameModeBase

: 게임규칙, 게임의 신 역할

ex) 롤에서 넥서스터지면 게임끝

생성자만듬 && 기본플레이어(가 사용할폰)을 MyPawn으로 설정

 

* MyPawn

:입력을 받을 수 있는 클래스

유니티 : update함수에 입력처리O => 종속성(-)

언리얼 : tick함수에 입력처리X, SetupPlayerInputComponent 함수에 입력부분 따로처리

 

* 바인딩 종류

액션 : 조이스틱 버튼

축(axis) : 조이스틱 손잡이

 

- WASD로 움직이도록 구현

// Called to bind functionality to input
void AMyPawn::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{
	Super::SetupPlayerInputComponent(PlayerInputComponent);

	PlayerInputComponent->BindAxis(TEXT("UpDown"), this, &AMyPawn::UpDown);
	PlayerInputComponent->BindAxis(TEXT("LeftRight"), this, &AMyPawn::LeftRight);
}

void AMyPawn::UpDown(float Value)
{
	UE_LOG(LogTemp, Warning, TEXT("UpDown %f"), Value);
}

void AMyPawn::LeftRight(float Value)
{
	UE_LOG(LogTemp, Warning, TEXT("LeftRight %f"), Value);
}

1. MyPawn에서 작업

PlayerInputComponent->BindAxis(엔진과 매핑될 이름,대상, 실행할함수)

2. 세팅-프로젝트설정-입력 설정

Scale값이 코드의 Value로 들어온다.

 

- 움직임 구현

유니티 : transform.positon += asdfsdaf ... 

단점 : 유동적 대응이 힘들다. ex)물위에서 걸을때, 땅에서 걸을때 등등

언리얼: UFloatingPawnMovement 클래스 에서 관리

void AMyPawn::UpDown(float Value)
{
	//UE_LOG(LogTemp, Warning, TEXT("UpDown %f"), Value);
	AddMovementInput(GetActorForwardVector(), Value);
}

void AMyPawn::LeftRight(float Value)
{
	//UE_LOG(LogTemp, Warning, TEXT("LeftRight %f"), Value);
	AddMovementInput(GetActorRightVector(), Value);
}

AddMovementInput(방향,스케일) : 키보드 S누르면 -1(엔진설정값)이 곱해짐 => 뒤로가게됨.

 

 

- 빌드오류

원인 : CoreMinimal.h에 UFloatingPawnMovement 가 포함안되있음

해결 : mypawn.h에 전방선언 && .cpp에 include

private:
	UPROPERTY(VisibleAnywhere);	//포인터타입 : visible->밖의 그래픽으로 조정가능
	UStaticMeshComponent* Mesh;

	UPROPERTY(VisibleAnywhere);
	class UFloatingPawnMovement* movement;

* 팁 : 컨트롤+N 맵설정, 세이브로저장, 세팅->맵->기본맵으로 설정
