Kivy 中的 Time.sleep

问题描述

我正在 Kivy 中寻找类似 time.sleep 的东西，因为 kivy 不支持 time.sleep 并且当我使用 运行程序时它会挂起time.sleep.我搜索并找到了一个名为:

I am looking for some thing like time.sleep in Kivy, because kivy does not support time.sleep and it hangs when i run a program using time.sleep. I searched and found a function called:

Clock.schedule_interval(self.callback, interval)

但它可能不像 time.sleep.Clock.schedule 每 x 秒调用一次函数，但我想延迟.

but its not probably like time.sleep. Clock.schedule calls a function every x seconds, but I want to make a delay.

kivy.clock

推荐答案

kivy 不支持 time.sleep

kivy does not support time.sleep

Kivy 支持 time.sleep 就好了，它只是不做你想让它做的事情 - 根据函数名称，它会休眠，这意味着 kivy '冻结'，因为它不接受输入，更新图形等等

Kivy supports time.sleep just fine, it just doesn't do what you want it to do - as per the function name, it sleeps, which means kivy 'freezes' as it isn't taking input, updating the graphics etc.

不管怎样，听起来你想要Clock.schedule_once(function, time).这将在 time 秒内调用函数(带有默认参数 dt).

Anyway, it sounds like you want Clock.schedule_once(function, time). That will call the function (with a default argument dt) in time seconds.
