我正在为我的Python编程课制作一个太空飞船游戏，我想使用sprite.spritecollideany检查我的玩家精灵spaceship是否与spriteGroup组中的任何行星精灵发生碰撞，但不管我做什么，似乎都不起作用。
这是代码：
import pygame
import random
pygame.init()
screen = pygame.display.set_mode((600, 600))
pygame.display.set_caption("Asteroids and Spaceships")
background = pygame.image.load("background.png")
background = background.convert()
white = 255,255,255
#first I make the asteroids with this class.
class asteroids(pygame.sprite.Sprite):
def __init__(self, x, y):
pygame.sprite.Sprite.__init__(self)
self.x = x
self.y = y
self.width = 30
self.height = 30
self.i1 = pygame.image.load("smallasteroid.png")
self.i1 = self.i1.convert()
self.i1.set_colorkey(white)
self.rect = self.i1.get_rect()
self.rect.left = x
self.rect.top = y
self.i2 = pygame.image.load("smallasteroid2.png")
self.i2 = self.i2.convert()
self.i2.set_colorkey(white)
self.rect = self.i2.get_rect()
self.rect.left = x
self.rect.top = y
self.i3 = pygame.image.load("mediumasteroid.png")
self.i3 = self.i3.convert()
self.i3.set_colorkey(white)
self.rect = self.i3.get_rect()
self.rect.left = x
self.rect.top = y
self.current = 0
def render(self, image_num):
if image_num == 1:
self.current = 1
if image_num == 2:
self.current = 2
if image_num == 3:
self.current = 3
def update(self):
if self.current == 1:
screen.blit(self.i1, (self.x,self.y))
self.y += random.randint(7,11)
if self.y > screen.get_height():
self.y = 0
if self.current == 2:
screen.blit(self.i2, (self.x,self.y))
self.y += random.randint(5,9)
if self.y > screen.get_height():
self.y = 0
if self.current == 3:
screen.blit(self.i3, (self.x,self.y))
self.y += random.randint(3,6)
if self.y > screen.get_height():
self.y = 0
#and then this is the class for the spaceship
class spaceship(pygame.sprite.Sprite):
def __init__(self, x, y):
pygame.sprite.Sprite.__init__(self)
self.x = x
self.y = y
self.width = 40
self.height = 60
self.image = pygame.image.load("spaceship.png")
self.image = self.image.convert()
self.image.set_colorkey(white)
self.rect = self.image.get_rect()
self.rect.left = x
self.rect.top = y
def update(self):
screen.blit(self.image,(self.x,self.y))
if self.y > screen.get_height():
self.y = 0
if self.y < screen.get_height()-610:
self.y = screen.get_height()
if self.x > screen.get_width():
self.x = 0
if self.x < screen.get_width()-610:
self.x = screen.get_width()
#main is where I have the game run
def main():
x_ship, y_ship = 0,0
player = spaceship(300,550)
spriteGroup = pygame.sprite.Group() #my asteroid sprites are grouped here
for i in range(25):
image_num = random.randint(0,3)
asteroid = asteroids(random.randint(0,500),random.randint(0, 200))
asteroid.render(image_num)
spriteGroup.add(asteroid)
clock = pygame.time.Clock()
keepGoing = True
while keepGoing:
#this is what I tried to use to check for collisions. I know it's not working but I don't know why.
if pygame.sprite.spritecollideany(player,spriteGroup):
#the program quits on collision.
pygame.quit()
for event in pygame.event.get():
if (event.type == pygame.QUIT):
keepGoing = False
elif event.type == pygame.KEYUP:
if event.key == pygame.K_ESCAPE:
keepGoing = False
if (event.type == pygame.KEYDOWN):
if (event.key == pygame.K_LEFT):
x_ship = -4
if (event.key == pygame.K_RIGHT):
x_ship = 4
if (event.key == pygame.K_UP):
y_ship = -4
if (event.key == pygame.K_DOWN):

if (event.key==pygame.K_DOWN):
y_ship = 0
player.x += x_ship
player.y += y_ship
screen.blit(background, (0,0))
spriteGroup.clear(screen, background)
player.update()
spriteGroup.update()
clock.tick(50)
pygame.display.flip()
pygame.quit()
main()
我弄不清楚为什么碰撞没有生效。
self.i1 = pygame.Surface((30,30)); self.i1.fill((255,25,25))而不是实际图像，因为我们手头没有这些图像），这样我们就可以运行它而不需要太多额外的编辑。我保留了原始的图像引用，这样对你仍然有意义，但下次这可能会帮助你（和我们）更好地理解问题！ - Augustaasteroids.__init__中的i2和i3数据，只要您确定它是辅助的而不是与错误有关的。 (有时候您可能很匆忙，只想完成它。) - Augusta
