Python 主菜单到游戏过渡

这段代码将打开一个pygame窗口，并显示一张带有功能按钮的图片（

主菜单

），但我想知道是否有办法让代码跳到底部（

def car（x，y）：

），在我按下

Go

按钮后游戏将从底部开始？如果有办法的话，我怎样才能做到这一点

你犯了一个愚蠢的错误——调用函数

car

你需要括号和参数（例如10,10）

顺便说一下：最好先检查

click！=无

，下一步

单击[0]==1

。 如果

单击

为

无

，则首先检查

单击[0]==1

将显示错误。如果

check

为

None

且您首先选中

单击！=无

然后

和

不选中

单击[0]==1

if click != None and click[0] == 1:
    print("GO == 1 ! == None")
    car(10, 10) # parenthesis and arguments
