pygame.sprite.collide_rect（）

需要两个

对象或具有

self.rect

改变

进入

然后使用

self.rect = self.image.get_rect()

---

顺便问一下：你为什么要用

 rock.collision(bird, rock) # without .image_b or .rect

代替

self.image = pygame.Surface([160,160])
self.image.set_colorkey(black)
self.image.blit(pygame.image.load(img_rock),(0,0))

self.image = pygame.Surface([160,160])
self.image.set_colorkey(black)
self.image.blit(pygame.image.load(img_rock),(0,0))

self.image = pygame.image.load(img_rock)
self.image.set_colorkey(black)
