J2ME를 이용해서 넷빈으로 짠 테트리스 코딩입니다.
클래스는 3개 이고 스페이스 기능을 추가하려하는데 잘안되네요.
도와주세요

    스페이스 기능이라는게 바닥에 툭 떨어지는 것 말이죠?
    (지금 소스상으로는 UP 기능과 동일하게 구현되어 있어서요..

    구현할수 있는 방법은 여러가지인데, 그중 가장 한가지 방법은
    case SPACE:
        for(i=0;i<30;i++) {  // normalProc() 함수를 조금 수정해서 사용하면 됩니다.
                                  // 30이라는 숫자는 Y 의 블럭수입니다.

            mby++;

      if(!moveOK()) { 
       mby--;
       freezeMovingBlock();
       canvas.repaint();

        formALine();  // 이거는 안해줘도 될거 같은데. 무슨함수인지 몰라서...

        break;
      }

            canvas.repaint();
      formALine(); 

    }

    그냥 이정도면 될거 같은데요...
    필요한 부분은 직접 수정해 보세요 .~~

    근봉봉 님에게 달린 댓글

    이 소스를 이해하셨다면 근봉봉님께서 직접 주석을 다시면 될것이고,
    이해하지 못하셨다면, 먼저 이해를 하셔야 합니다.
    (구체적으로 어느 부분이 이해가 안되는지를 알려 주시면, 그정도는 해 드릴수가 있는데,
    전체적으로 해달라는 것은 좀 그렇네요. 저도 먹고 살기 바빠서요 ^^.)

    일단 하시는데 까지 해보세요...^^

    어느 for 문 말인가요^^?
    for문이 한두개가 아닌데요 ㅡㅡ;

    댓글에 for문 소스를 올려 보세요.^^

    운영자님께서 제 질문에 올려주신 스페이스 소스중에
     for(i=0;i<30;i++)  <--이부분 있잖아요~
    이부분을 이해하기가 좀 어려워서용;;나머지들은 메서드를 호출하는 거라서
    금방 알겠는데요;ㅋㅋ;;
     for(i=0;i<30;i++)  <-- 여기는 이상하게 어렵네요ㅜㅜ
