카메라 추가

1. Camera & Spring Arm

• Camera는 우리가 늘 아는 카메라
• Spring Arm은 카메라가 벽에 막힐 때 늘어났다 줄어들었다 하는 스프링 역할을 수행함. Unity에서는 Cinemachine에서 설정해야 했던 것을 여기서는 Component 하나로 해결 가능함.

1-1. 계층구조

• Spring Arm > Camera 순으로 이루어져야 정상적으로 작동한다.

 

2. 추가하기

Bird.h

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Pawn.h"
#include "Bird.generated.h"

class USpringArmComponent;
class UCameraComponent;

UCLASS()
class SLASH_API ABird : public APawn
{
	GENERATED_BODY()
	
private:
	UPROPERTY(VisibleAnywhere)
	USpringArmComponent *CameraBoom;

	UPROPERTY(VisibleAnywhere)
	UCameraComponent *ViewCamera;
};

Bird.cpp

ABird::ABird()
{
	CameraBoom = CreateDefaultSubobject<USpringArmComponent>(TEXT("SpringArm"));
	CameraBoom->SetupAttachment(GetRootComponent());
	CameraBoom->TargetArmLength = 300.f;
	
	ViewCamera = CreateDefaultSubobject<UCameraComponent>(TEXT("ViewCamera"));
	ViewCamera->SetupAttachment(CameraBoom);
}
