通过while while循环检查事件中途？

Question

因此，与pygame的，你有一个while循环不断循环，那么你的事件处理程序在for循环中，那么你想要的代码继续执行。

我需要后，我执行while循环，虽然他们怎么一回事，因为冲击对方内线一行代码来处理事件，但我也需要前行来处理不同的事件。

怎么样，我的主while循环中，处理一组事件，执行一些代码，然后再处理另一组事件？

Answer 1

解决。

我在用户事件处理程序中设置了一个等于1的变量，然后在需要执行代码的位置，我检查变量是否等于1，如果是，我执行我的代码并设置变回0

好东西。

这里是我的代码，如果有人想帮我找一个更好的解决办法;）（有点长）：

uif = "images/userGray.png" 
bif = "images/bg.jpg" 
cif = "images/chair3.png"

pY = 1 
bX = 0 
bY = 0 
moveX = 0 
moveY = 0 
windowX = 640 
windowY = 480 
lowerY = 1024 
lowerX = 1024
