Lecture 마우스 이벤트

마우스 이벤트

마우스의 버튼에 따른 명령이 동작하게하기 위한 루틴은 다음과 같다.

if event.type == pygame.MOUSEBUTTONDOWN:
   if event.button == pygame.키상수:
      명령 모음

x,y = pygame.mouse.get_pos()  # 마우스 위치를 얻는 명령어

pygame.mouse.get_pressed( ) # 마우스 버튼의 상태를 얻는다.

마우스 이벤트 키 상수

pygame.MOUSEMOTION

마우스가 움직이면 발생하는 참을 반환
