무기 장착 및 기본 공격하기

프로그래밍 설계의 진화

Top-Down 방식

초기(과거) 프로그래밍 설계
기능함수, 데이터 변수 수정에 대한 비용이 너무 크다는걸 인지.

그 후에 이 문제를 해결하기 위해...

객체(함수 + 변수)가 등장!!

요즘은 객체를 사용하여 프로그래밍한다.

Weapon 구조


	WeponComponent	WeaponAsset	Attachment Equipment - OnEquip Event - OnUnequp Event DoAction

같은 레벨의 클래스를 부르는 방법

Delegation 사용하는 방법
- 부분적으로 사용할 때 가장 좋은 방법
- ex. WeaponComponent → WeaponAsset → Equipment(에서 Event 발생 시 Delegation과 엮여있는 Attachment 내의 함수를 호출)
Friend를 사용하는 방법
- 클래스에서만 사용되는 부분은 private으로 막아준다.
- 다른곳에서 사용되는 부분을 public으로 열어준다.

CEquipment

델리게이트 생성

직렬화하여 BP에서 사용가능하도록 DYNAMIC, 여러함수를 받을 수 있도록 MULTICAST 사용.
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FEquipmentBeginEquip);
DECLARE_DYNAMIC_MULTICAST_DELEGATE(FEquipmentUnequip);

델리게이트를 사용한 함수 선언

FEquipmentBeginEquip OnEquipmentBeginEquip;
FEquipmentUnequip OnEquipmentUnequip;

}

Begin_Equip_Implementation()

OnEquipmentBeginEquip.Broadcast(); 해준다.

Unequip_Implementation()

OnEquipmentUnequip.Broadcast(); 해준다.
