我正在制作一个非常简单的游戏,鸟(玩家)必须躲避石头,如果被石头击中,你就输了。我试图使用pygame.sprite.collide_rect()来判断它们是否接触,但我似乎无法弄清如何正确使用它。
以下是我的代码:
import pygame
import os, sys
import random
import time
img_path = os.path.join('C:\Python27', 'player.png')
img_path2 = os.path.join('C:\Python27', 'rock.png')
class Bird(object):
def __init__(self):
self.image_s = pygame.image.load(img_path)
self.image_b = self.image_s.get_rect()
self.x = 0
self.y = 0
def handle_keys(self):
key = pygame.key.get_pressed()
dist = 2
if key[pygame.K_DOWN]:
self.y += dist
elif key[pygame.K_UP]:
self.y -= dist
if key[pygame.K_RIGHT]:
self.x += dist
elif key[pygame.K_LEFT]:
self.x -= dist
def draw(self, surface):
surface.blit(self.image, (self.x, self.y))
def background(self, surface):
bg = os.path.join('C:\Python27', 'bg.png')
self.image2 = pygame.image.load(bg)
surface.blit(self.image2, (0,0))
class Rock(object):
def __init__(self, x=640, y=0,):
self.image_s = pygame.image.load(img_path2)
self.image_b = self.image_s.get_rect()
self.x = x
self.y = y
dist = 10
self.dist = dist
def rock(self):
dist = 10
self.x -=dist
def rock_draw(self, surface):
surface.blit(self.image, (self.x, self.y))
def checkCollision(sprite1, sprite2):
col = pygame.sprite.collide_rect(sprite1, sprite2)
if col == True:
sys.exit()
pygame.init()
screen = pygame.display.set_mode((640, 200))
bird = Bird()
rock = Rock()
clock = pygame.time.Clock()
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
running = False
if rock.x < 0:
y = random.randint(10, 190)
rock = Rock(640, y)
rock.checkCollision(bird.image_b, rock.image_b)
bird.handle_keys()
rock.rock()
screen.fill((255,255,255))
bird.background(screen)
bird.draw(screen)
rock.rock_draw(screen)
pygame.display.update()
clock.tick(40)
当我尝试运行它时,它告诉我只需要2个参数,但我提供了3个,当我试图修复它时,我会得到各种不同的错误消息。
collide_rect
是sprite的实例方法,那么你需要这样调用它:sprite1.collide_rect(sprite2)
。如果它是rect的实例方法,则在sprite1的rect上调用它。以此类推。 - Patashuif pygame.sprite.collide_rect(rock.image_b, bird.image_b)==True: sys.exit()
但我收到以下错误信息:Traceback (most recent call last): File "C:\Python27\BIRDGAME.py", line 111, in <module> if pygame.sprite.collide_rect(rock.image_b, bird.image_b)==True: File "C:\Python27\lib\site-packages\pygame\sprite.py", line 1147, in collide_rect return left.rect.colliderect(right.rect) AttributeError: 'pygame.Rect' object has no attribute 'rect'
- Serialrect
的参数,而它期望有一个。所以你需要传递一个带有属性rect
的参数。 - Patashu
