limitations to WHILE loop?

[Guest reiniertc]

I've made a scene with a WHILE loop, but somehow it stops after aprox 6 hours.

 

 

the basic setup of the scene is:

while true do [some code that runs function 1 and function 2
wait for 55 seconds by using function 3 end

 

 

Are there any know generic limitations to a WHILE loop that would cause it to stop after 6 hours?

not that i know of.

"While" doesn't crash by itself. But some lua code can crash. It can happen to http calls. You can catch these errors with "pcall" (please search this forum or check the lua manual).

thanks petergebruers, maybe some http calls might cause the scene to stop.

I will search the forum on "pcall"

mmm... the scene quits again after 6 hours when I use pcall, but no errors show up

I hate to say it, I'm quite certain that it's your script. I mean, it's not the "while" loop. It was never mentioned before on the forum and I have several scripts with an infinite loop. But none of them use http, that's why I thought about the pcall. What has been mentioned before is that the main loop of a virtual device stops working, and that's essentially a (non-visible) infinite loop. So maybe you've discovered a related problem.

Would it be possible to reduce your script to the absolute minimum, with a maximum of 10 lines of code, so someone can try to reproduce your problem?

I've made some infinite while loops with almost no code: no problems there.

So indeed Peter: It must be the script.

 

so now I've reduced the code in my problamatic while loop.

At first, I've greyed out the content of the two  functions that are called every minute.

If the result is that the while loop works fine, the problem must be in one of the two functions.

 

If the problem is still there, I'm gonna undo the greying out of the functions and reduce the amount of function calls every minute.

 

 

ps: the script itself doesnt contain http-calls, it calls some virtual device buttons that performs the actual http call

Sounds like a plan!
