[파이썬] 지렁이게임 만들기 - pygame

[파이썬] 지렁이게임 만들기 - pygame

Chat GPT를 활용하여 지렁이 게임을 만들어 보았다. 

 

Chat GPT에게 

pygame을 활용하여 지렁이 게임을 만드는 코드를 알려줘

라고 요청하면, 

아래와 같은 코드를 알려준다. (매번 조금씩 바뀐다)

 

1. chat GPT에게 지렁이게임 코드 물어보기

2. 파이썬에 pygame 설치하기

pip install pygame

3. 아래의 코드를 파이썬에 붙여넣는다. 

4. 화면사이즈, 색깔, 방향 등을 내가 원하는 값으로 변경해 주었다.
