我正在为游戏（学校项目）编写代码。 我有一个具有不同图像的对象。 我想要的是创造一个碰撞的条件。例如，如果火灾图像碰撞地球图像，则获得新图像。 我该怎么办？
谢谢！

答案 0 :(得分：0)
也许是这样的：
earth = pygame.image.load("earth.png").convert()
earthRect = earth.get_rect()
fire = pygame.image.load("fire.png").convert()
fireRect = fire.get_rect()
if earth.colliderect(fire):
earth = pygame.image.load("thirdimage.png")
前四行定义我们的图像和用于检测碰撞的rect对象，最后两行检测碰撞并更改图像文件
