Retry after delay without blocking possible (similar to setTimeout() in JS)?
Retry after delay without blocking possible (similar to setTimeout() in JS)?

Hey,
is there a way to retry some operations after some time or delay the execution of some operations without blocking.
I need something like setTimeout() from JavaScript.
I tried out the sleep() function but it blocks the execution and if my Websocket message handler calls the sleep function it doesn't receive further messages as long sleep() function is active…

I figured it out myself. If anybody need somehting similar just try this pattern (BeginInvokeOnMainThread very important otherwise your code will be buggy and forget the “await” operator it will not work because thread will be changed after await):
Task.Delay(waitInMs)
.ContinueWith((t) => BeginInvokeOnMainThread(() => yourRetryOperation()));@qwer1993

the calgo documentation specifically states:
“The sleep functionality is available only for .NET 6 algos. While a cBot stays in sleep mode, all other events in the code will be ignored.”
If you need to do other things, then you obviously need to set your own timer and check if after x-seconds/minutes/hours/whatever.
So create your own timer, and set a flag after the desired amount of time has elapsed. When the flag is set to true, then continue executing whatever code you need to. In the mean time, you should still be able to listen to messages from whatever sockets you have set up.
