python - PGU(Phil's pyGame Utilities) - 访问主更新循环

Question

所以我正在使用 PGU 在 pygame 中制作一个应用程序。我无法弄清楚如何访问主更新循环。我有一个很好看的事件界面，但是我也有一些网络代码需要在每个循环中发生（检查服务器是否向我发送了任何东西）。如何让我的代码执行每个循环？

我在想也许在 pgu 中总会发生一些事件，如果是这样，那么我可以捕捉到这个事件，并执行我的服务器检查代码。

如果你们需要任何其他信息，请询问，如果需要，我可以发布我的代码。谢谢

Maythe has already mentioned this, but what you need to use is the app.loop function. So, say you have a function that will do everything you want to happen on top of the mainloop, called dosomething, you would do this:

myapp = gui.App()
myapp.init(widget=<your root widget>)
while True:
    dosomething()
    myapp.loop()

In fact, I looked at the pgu code online, and all that mainloop does is:

while True:
    myapp.loop()
    time.sleep(wait)   #this is just a routine wait each iteration you give it

So you really are directly adding code on top of the update function, without any unwanted side effects.
