5가지 실전 게임으로 배우는 코코스2d-x(cocos2d-x) 모바일 2D 게임 개발 두번째 예제(3)

이번 포스팅은 상당히 오래걸렸습니다..

왜냐하면 2.x 버전을 3.x 버전으로 바꾼다는게 생각보다 상당히 어렵더군요.

아에 없어진 것들을 새로 생긴것으로 바꾸자니 전체를 바꿔야 해서 차라리 새로운 게임을 만드는게 더 쉽게 느껴졌습니다.

일단 현재까지 진행한 소스는 다음과 같습니다.

이번에 구현한것은 좀 여러가지인데 일단  update메소드와 fallenobject쪽입니다.

array를 사용했던 것들을 전부 벡터로 바꿔주고, array관련 메소드들을 벡터로 바꾸니 생각보다 시간이 많이 걸렸습니다. 또 터치 이벤트도 3.x에서 사용법이 바꼈구요.

그래서 아직 전체 코드를 완성시키지 못했습니다.

하지만 구동은 됩니다. 헤더 코드도 올릴태니 한번 돌려보세요~

게임 진행과 점수계산까지는 됩니다 ^^
