파이 게임에서 스프라이트 마스크 충돌 문제가 발생했습니다.

Question

파이 게임에서 레이싱 게임을 만들려고합니다. 차가 트랙을 벗어나면 속도가 느려지 길 바랍니다. 나는 트랙의 윤곽선 인 또 다른 스프라이트를 가지고 이것을하려고했는데, 자동차가 스프라이트에 닿으면 속도가 느려진다. 이것은 작동하지 않으며 이유를 모르겠습니다. 이 작업을 수행하는 더 좋은 방법이 있습니까?

Traceback (most recent call last): File "C:\Users\Daniella\Desktop\Python\Games\game.py", line 75, in if pygame.sprite.collide_mask(Img, BackHit): File "C:\Users\Daniella\AppData\Roaming\Python\Python36\site-packages\pygame\sprite.py", line 1470, in collide_mask xoffset = right.rect[0] - left.rect[0] AttributeError: 'pygame.Surface' object has no attribute 'rect'

다음은 픽셀 완전 충돌 감지에 pygame.mask.from_surface 및 pygame.Mask.overlap을 사용하는 방법을 보여주는 약간의 예입니다.

import pygame as pg 

# Transparent surfaces with a circle and a triangle. 
circle_surface = pg.Surface((60, 60), pg.SRCALPHA) 
pg.draw.circle(circle_surface, (30, 90, 200), (30, 30), 30) 
triangle_surface = pg.Surface((60, 60), pg.SRCALPHA) 
pg.draw.polygon(triangle_surface, (160, 250, 0), ((30, 0), (60, 60), (0, 60))) 


def main(): 
    screen = pg.display.set_mode((640, 480)) 
    clock = pg.time.Clock() 

    # Use `pygame.mask.from_surface` to get the masks. 
    circle_mask = pg.mask.from_surface(circle_surface) 
    triangle_mask = pg.mask.from_surface(triangle_surface) 

    # Also create rects for the two images/surfaces. 
    circle_rect = circle_surface.get_rect(center=(320, 240)) 
    triangle_rect = triangle_surface.get_rect(center=(0, 0)) 

    done = False 

    while not done: 
     for event in pg.event.get(): 
      if event.type == pg.QUIT: 
       done = True 
      elif event.type == pg.MOUSEMOTION: 
       triangle_rect.center = event.pos 

     # Now calculate the offset between the rects. 
     offset_x = triangle_rect.x - circle_rect.x 
     offset_y = triangle_rect.y - circle_rect.y 

     # And pass the offset to the `overlap` method of the mask. 
     overlap = circle_mask.overlap(triangle_mask, (offset_x, offset_y)) 
     if overlap: 
      print('The two masks overlap!', overlap) 

     screen.fill((30, 30, 30)) 
     screen.blit(circle_surface, circle_rect) 
     screen.blit(triangle_surface, triangle_rect) 

     pg.display.flip() 
     clock.tick(30) 


if __name__ == '__main__': 
    pg.init() 
    main() 
    pg.quit()

는 배경 마스크를 생성하거나 자동차가 충돌 여부를 확인 후 별도의 이미지를 생성하고 중 차량이 감속해야한다 트랙 투명 또는 지역을 떠나 필요 추적하려면 트랙 또는 외부 영역. 여기에서 녹색 삼각형이 "트랙"(파란색 선)과 충돌하는지 확인하고 게임에서 충돌이 트랙과 충돌하지 않으면 차를 느리게 만듭니다.
