Python pygame.Rect.colliderect（）给我错误

我正在做一个游戏，我需要做碰撞检测。我决定使用函数

pygame.Rect.colliderect（）

。但是，它给了我一个错误：

pygame 2.0.0.dev6 (SDL 2.0.10, python 3.7.2)
Hello from the pygame community. https://www.pygame.org/contribute.html
Traceback (most recent call last):
  File "C:/Users/admin/PycharmProjects/ProgrammingLearn/SpaceInvaders.py", line 185, in <module>
    main()

    if pygame.Rect.colliderect(blue_enemy_rect):
TypeError: Argument must be rect style object

我看不出这里有什么不对，因为我相信这就是colliderect的用法。 我真的很快就要完成这个项目了，非常感谢您的帮助。谢谢。

是一种实例方法（请参阅）。该方法测试两个矩形是否重叠。它需要用两个矩形来调用

或者

如果pygame.Rect.colliderect（rect1，rect2）：
# [...]

或

如果rect1.collide rect（rect2）：
# [...]

---

这意味着您可以执行以下操作：

blue\u敌军\u rect=pygame.rect（30,35,80,70）
绿色敌人方阵=pygame.rect（180,35,60,70]）
# [...]
尽管如此：
# [...]
如果绿色敌人冲突（蓝色敌人）：
蓝色敌人健康=蓝色敌人健康-1

这确实有效！
