使用 python 和 pygame 编码和创建游戏的新手。游戏类似于Flappy鸟，但在太空中，管道是流星。
正在创建精灵碰撞时的事件，但 pygame.sprite.spritecollide 函数似乎无法正常工作。该功能在精灵实际触摸之前一英寸左右(在屏幕上(触发。如果玩家精灵从流星精灵中掉落，则不会触发该事件。

如果碰撞检测出现问题，绘制(或打印(相关精灵的矩形通常会有所帮助。 您不会在矩形的 x 坐标处对图像进行块传输，因此矩形实际上会更靠右。
screen.blit(self.image, (320, self.rect.y)) # self.rect.x is equal to `HW` not 320.
只需在矩形处将图像点缀
：screen.blit(self.image, self.rect)
