xLua - pause execution

[Looki]

Sorry if this has been asked already, but is there a way to pause the script execution in xLua? I've always wanted this feature, but never asked for it anywhere. Theoretically, it must be possible, but I'm not sure if it's part of Lua or Retriever2 would have to code it, which would involve much more programming, I suppose.
Is there a way?

I don't think you can arbitrarily pause, say via an action, but you should look into coroutines which will let you yield out of a function, essentially pausing it at that point and letting you resume later. In fact I just recently fixed the coroutine support.

Thanks, will do.

[Retriever2]

Also, did I interpret your question correctly or were you possibly referring to a sleep function to briefly pause script execution without returning control to mmf?

[Looki]

No. I want something like this:

There's a robot on the screen.

The script is
walk_left()
walk_up()

What happens: The robot walks left, say, 20 px. After that, it walks up 20 px.

yeah coroutines will help anywhere you have a batch of commands you want to run that might need to be spread over several frame loops.
