퍼즐 게임 만들기12 - 빈칸 채우기

슬슬 복잡해지고 있다

또 한번 전체적으로 수정을 해야했다.

미리 다 완성한 다음 쓰는 글이 아니라서

계속 수정하고 있다

더 이상 소스를 설명할 자신이 없다.

최대한 주석을 많이 달았다.

주요 사항

블록이 이동 중일 때 그 블록을 낚아챌 수 있었다

 블록이 이동 중일 때 터치를 비활성화 하게 했다.

 

블록 제거

 기존에 setVisible(false)를 사용해 눈에 만 안보이게 했던 것을

실제로 m_pBoard[][]에서 제외시키고 removeChild()를 통해 화면에서 삭제시켰다.

 

빈칸 채우기

 아래쪽 라인부터 검사하여

자기 위쪽으로 가장 가까운 블록을 찾아 땡겨온다.

만약 자기 위쪽으로 블록이 존재하지 않으면

블록을 생성해서 가져온다.

 

블록을 땡기는 속도

 블록을 반복문을 돌며 블록을 한칸 씩 내리는게 아니라

한번에 쭈욱 내리는거라 속도를 제어할 필요가 있다.

2칸 움직이는 블록은 2배로 3칸 움직이는 블록은 3배로 움직이게 해야한다.

 

게임이 시작된 직후 처음부터 콤보가 만들어져 있는 곳이 있다

 블록 초기화 후 매칭 검사->블록 삭제->빈칸 채우기를 수행하게 했다.

 

 

괜히 육각형으로 했다

 사각형으로 했으면 간단했을 텐데

육각형 좌표계를 잘못 구상한 건지

로직이 복잡하다.
