当我按Run时，我的启动屏幕不会启动！按钮

Question

因此，自从我为我的游戏添加了我的开始屏幕，以及何时我会按Run/“开始”按钮不起作用，屏幕会冻结，我不能按任何按钮。我的静坐/退出功能非常好，但我的跑步/启动功能不好

正如你们从我的简短演示中所看到的，若我按下Run/Start按钮，我的游戏就会停止运行。我尝试过重写我的代码，但仍然不起作用，我想我遗漏了一些东西，但我不知道是什么

这就是我的问题所在

Answer 1

所以这就是你开始游戏的地方

    button("Run!",100,350,100,50,darkgreen,green,main_loop)
    button("Sit!",300,350,100,50,darkred,red,quitgame)

我想说的是不要像这样直接运行主循环。好啊您想做的是，您想更改与事件相关的状态的操作已触发。否则，您将过度运行主循环，因为您在while循环中已经准备好了。将此函数引导到一个函数，在该函数中，全局变量的状态如下所示。并让主函数基于该全局变量的状态运行

button("Run!",100,350,100,50,darkgreen,green,main_loop_state_turn_on)

然后继续评估它相对于按钮的位置

event_i = False

def main_loop_state_turn_on():
    global event_i = true

def main_loop_state_turn_off():
    global event_i = false

在主循环中，如果这些全局变量为true，则可以运行while循环

def main_loop():
      if event_i:
         print 'Begin'
         #your code is going on here
