스네이크 게임 경계

Question

나는이 뱀 게임을 만들기 시작했고 나는 투쟁에 부딪쳤다. 나는 뱀이 한쪽 끝까지 도달하면 다른 쪽에서 올 것입니다. 왼쪽 끝 부분에 도달하면 오른쪽면에서 나오고 위쪽 끝 부분에 도달하면 뱀 바닥 부분에서 나오게됩니다. . 누군가가 저에게 어떻게하는지 보여줄 수 있다면 정말 고마워요.

Answer 1

당신은 위치를 확인하기 위해 if를 사용하고 다른 쪽

x = snake_segments[0].rect.x + x_change 
y = snake_segments[0].rect.y + y_change 

if x < screen_rect.left: 
    x += screen_rect.width 
elif x + segment_width + segment_margin > screen_rect.right: 
    x -= screen_rect.width 

if y < screen_rect.top: 
    y += screen_rect.height 
elif y + segment_height + segment_margin > screen_rect.bottom: 
    y -= screen_rect.height 

segment = Segment(x, y) 

로 이동하지만 문제는 세그먼트가 이상적으로 화면을 채울하지 않는다는 것입니다 수 - 때로는 한쪽 나머지 세그먼트의 부분을 표시한다 다른쪽에. 두 번째 세그먼트를 그려야하고 두 세그먼트를 그려야하는지 확인하는 방법 draw()을 Segment에 추가해야합니다. 먼저 한쪽에는, 다른 한쪽에는 두 번째 세그먼트를 그립니다.

def draw(self, screen): 

     # draw oryginal segment 

     screen_rect = screen.get_rect() 
     screen.blit(self.image, self.rect) 

     # draw second segment on other side 

     # left - right 
     if self.rect.left < screen_rect.left: 
      temp_rect = self.rect.copy() 
      temp_rect.x += screen_rect.width 
      screen.blit(self.image, temp_rect) 
     elif self.rect.right > screen_rect.right: 
      temp_rect = self.rect.copy() 
      temp_rect.x -= screen_rect.width 
      screen.blit(self.image, temp_rect) 

     # top - bottom 
     if self.rect.top < screen_rect.top: 
      temp_rect = self.rect.copy() 
      temp_rect.y += screen_rect.height 
      screen.blit(self.image, temp_rect) 
     elif self.rect.bottom > screen_rect.bottom: 
      temp_rect = self.rect.copy() 
      temp_rect.y -= screen_rect.height 
      screen.blit(self.image, temp_rect) 

그러나 직접 group.draw() 실행 screen.blit(self.image, self.rect)

for x in allspriteslist: 
    x.draw(screen)
