[Python] 파이썬으로 작성한 테트리스

by 꽃의비밀 2017. 10. 26.

이번 포스트에서는 파이썬으로 작성된 테트리스 소스를 공유해 드립니다. 이 소스는 제가 직접 작성한 코드는 아니고 누군가 작성해놓은 코드를(일종의 OpenSource겠죠?^^) 제 포스트에 공유하기로 했습니다. 


  • 개발 환경

Windows 10 64bit, Python 3.5 기반에서 테스트를 하였습니다. 소스를 보시면 PyQT4를 사용을 하는데, Anaconda 2.4.0 (32bit)용을 사용하였습니다. Anaconda를 설치하시면 PyQT가 기본적으로 설치가 되어 있으므로 별도의 설치를 하지 않으셔도 됩니다.

 사용법은 이동은 화살표키, 블럭 빨리 떨어트리기는 스페이스바를 누르면 됩니다. 다시 시작은 테트리스를 다시 실행을 시켜야 됩니다. 추가적인 기능은 분석하시면서 코드를 추가해 보시기 바랍니다.

      답글이 늦었습니다. 확인해 보니 다른곳인거 같네요. 제가 공유를 한 시점에는 PyQT4를 사용하여 작성한 소스를 인용하였는데, 아마 널리 다른곳에서 공유가 되나 봅니다.

      지적 감사합니다. 미처 출처를 남기는 것을 깜빡했군요^^
