PBullet 발사체 만들기

발사체를 만들어보자. 충돌체와 메시 그리고 움직임을 담당할 ProjectileMovementComponent를 컴포넌트로 추가하는 코드다

#include "CoreMinimal.h"

UCLASS()
class P231113_API APBullet : public AActor
{
	GENERATED_BODY()

public:
	// Sets default values for this actor's properties
	APBullet();

protected:
	// Called when the game starts or when spawned
	virtual void BeginPlay() override;

public:
	// Called every frame
	virtual void Tick(float DeltaTime) override;

public:

	UPROPERTY(VisibleAnywhere, Category = "Movement")
	class UProjectileMovementComponent* movementComp;

	UPROPERTY(VisibleAnywhere, Category = "Col")
	class USphereComponent* collisionComp;

	UPROPERTY(VisibleAnywhere, Category = "Mesh")
	class UStaticMeshComponent* meshComp;

//public:
	//void Die();
};

 

발사체의 초기설정및  2초 발사체가 사라지게 타이머를 추가하였다

PBullet.cpp

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


#include "PBullet.h"
#include "Components/SphereComponent.h"
#include "GameFramework/ProjectileMovementComponent.h"

// Sets default values
APBullet::APBullet()
{
	// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.
	PrimaryActorTick.bCanEverTick = true;

	collisionComp = CreateDefaultSubobject<USphereComponent>(TEXT("CollisionComp"));
	collisionComp->SetCollisionProfileName(TEXT("BlockAll"));
	collisionComp->SetSphereRadius(13);
	RootComponent = collisionComp;

	meshComp = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("MeshComp"));
	meshComp->SetupAttachment(collisionComp);
	meshComp->SetCollisionEnabled(ECollisionEnabled::NoCollision);

	//발사체 컴포넌트 생성
	movementComp = CreateDefaultSubobject<UProjectileMovementComponent>(TEXT("MovementComp"));
	// 발사체 컴포넌트를 update 시킬 컴포넌트 지정, 
	// update == tick, update ->매프레임 연산하겠다
	movementComp->SetUpdatedComponent(collisionComp);
	// 초기속도
	movementComp->InitialSpeed = 3000.f;
	// 최대속도
	movementComp->MaxSpeed = 5000.f;
	// 반동,
	movementComp->bShouldBounce = true;
	// 반동 크기
	movementComp->Bounciness = 0.3f;

	//생명 길이 (단위, 초)
	//InitialLifeSpan = 2.0f;
}

// Called when the game starts or when spawned
void APBullet::BeginPlay()
{
	Super::BeginPlay();

	//타이머 조작 하는 변수 ~= 알람, 언리얼 기능 (Tool)
	FTimerHandle deathTimer;
	//GetWorld()->GetTimerManager().SetTimer(deathTimer,this,&APBullet::Die, 2.0f,false);
	//(알림, 알림처리를 할 객체, 알림 처리 함수, 알림 시간, 반복 여부, 첫 호출 전 딜레이 시간)

	//FTimerDelegate ~= 언리얼 Timer관련 delegate를 관리하는 클래스 
	GetWorld()->GetTimerManager().SetTimer(deathTimer, FTimerDelegate::CreateLambda([this]()->void {Destroy(); }), 2.0f, false);
}

// Called every frame
void APBullet::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
}

//void APBullet::Die()
//{
//	Destroy();
//}

여기가지 입력하고 언리얼에디터를 끄고 빌드하면 된다.
