공이 파이썬, 패기 (브레이크 아웃 레크 리 에이션)

Question

에서 외륜을 치는 경우에만 공을 튀게 만드는 방법이 누구든 도와 줄 수 있습니까? 공이 패들에 부딪쳤을 때이를 감지하고 rect_change_y 변수를 변경하여 바운스를 감지하는 간단한 방법을 만드는 데 문제가 있습니다. 여기는 작동하는 코드이지만 공이 패들과 상호 작용하지 않거나 게임의 바닥에 닿았을 때 죽지 않습니다.

    clock.tick(100) 

pygame.quit() 

다음은 (나에게) 효과가 있지만 작동하지 않는 코드입니다.

    pygame.display.flip() 

    clock.tick(100) 

pygame.quit() 

마침내, 블록을 만드는 방법과 공을 대신 파괴하는 것을 제외하고는 똑같은 방법을 제안합니다.

감사합니다. 모두들!

Answer 1

당신은 볼과 노를 대표하는 Rect 클래스를 사용하고, 또한이 클래스가 제공하는 방법을 활용할 수 있습니다

myrect = pygame.Rect(0, 0, 10, 10) 
myrect.move_ip(100, 50) 

:

• Rect.move_ip이 자리에 사각형을 이동

  내역 왼쪽 위 모서리는 (100, 50)이며 동일한 너비와 높이를 유지합니다.

• Rect.clamp_ip 사각형이 모두 화면 안에 들어가도록하십시오.

  myrect = pygame.Rect(100, 0, 10, 10) 
  bounds = pygame.Rect(0, 0, 50, 50) 
  myrect.clamp_ip(bounds) 
  

  myrect 왼쪽 상단 모서리 (40, 0) 경계 내부 (10, 50)에서의 오른쪽 하단 직사각형이다.

• Rect.colliderect 공과 외륜이 충돌하는지 확인하십시오.

  myrect = pygame.Rect(0, 0, 10, 10) 
  another = pygame.Rect(5, 5, 10, 10) 
  print(myrect.colliderect(another)) # 1 
  

  myrect 및 다른 중복, 당신은 colliderect를 호출 할 때이 두 사각형 사이에 충돌이 있음을 나타내는 1을 반환 이후.

  정말 파이 게임처럼, 그래서 이러한 제안을 적용하는 프로그램을 재 작성 괜찮다
