[언리얼] 3번째. 스포너

오늘 한 것! 

시간마다 캐릭터 스폰하는 컨포넌트를 만듦

 

지들끼리 콜리전 안 끔 + 캐릭터 이동 안함 + 애니메이션 안넣음... 환장! 

 

스포너

(기본 스포너) 

일정한 시간당 n마리씩 특정 캐릭터를 스폰시킨다

 

(스폰 인터렉션)

캐릭터가 닿으면 

그 수를 사칙연산한다...

ㄴ 얘는 기존 캐릭터 Destroy하고 새 캐릭터 스폰하는거일텐데??

 

스폰캐릭터..

 

액터컴포넌트로 만들어야겠다.~ 둘 다 붙이게

 

ACharacterSpawnComponent

- float : TimeInternal

- TSubClassOf<ACharacter> : SpawnCharacterClass : 나중에 테이블로 바뀔 여지 있음.

 

- ESpawnType : + - * /  스포너로 늘이고 줄일 캐릭터 연산자 타입 

ㄴ 줄이는것도 있는데 스포너라는 말이 안어울리는 것 같음..

     ㄴ 걔는 디스포너야!!! 다른거야

+ 캐릭터풀도 필요함!!

 

* 캐릭터에 코드로 붙여놨던 카메라 떼어버리고, 

기본 빙의한 폰에만 붙여놨다.

 

+ 스폰 위치 코드로 박아놨었는데 에디터프리뷰 카메라 위치로 시작 폰 스폰되는거같다. 이유 확인하기.!
