도움이 필요합니다. 나는 파이썬에서 tkinter를 사용하여 나의 탁구 같은 게임에 작은 문제가있다. 게임은 예상대로 작동하지만 'self.height'변수의 범위에서 임의의 y 위치에서 타원이나 공을 시작하려고합니다. 저는 누군가 파이썬을 도울 수 있는지 궁금합니다.tkinter 게임에서 타원형 위치 초기화
() 메소드의 # NEED HELP는 공이 중간보다 오른쪽이 아닌 임의의 높이에서 시작되도록하려는 것입니다.
미리 감사드립니다.
self.y = random.randint(self.radius, self.height - self.radius)
을하지만 당신은 변경해야합니다 :
