python - 在pygame中随机创建图像

Question

我是编程新手，我正在尝试使用 pygame 制作一个简单的汽车游戏，一切正常，直到我尝试使汽车从相反方向随机出现，我成功地使矩形随机出现，但是当我想使用矩形 Sprite ，但它不起作用，我得到的错误是:

Traceback (most recent call last): File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 241, in game_intro() File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 158, in game_intro button("START",150,450,100,50,red,green,'Play') File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 89, in button game_loop() File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 190, in game_loop truck(tx,ty) File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 32, in truck gameDisplay.blit(truck(tx,ty)) File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 32, in truck gameDisplay.blit(truck(tx,ty)) File "C:/Users/saifo/PycharmProjects/untitled/gamev2.py", line 32, in truck gameDisplay.blit(truck(tx,ty)) [Previous line repeated 992 more times] RecursionError: maximum recursion depth exceeded

您在方法之间调用函数，这是非常糟糕的!

可能的答案:

Pygame - RuntimeError: maximum recursion depth exceeded while calling a Python object

祝你好运!
