So I'm trying to build a simple while loop.
It's just something like this:




So if you're wondering why I have the if whileindex and the break in there it's because the loop wasn't breaking on it's own.

So here's what happens:

You run the loop -
it gets to 100, never goes higher, locks in the loop.
So I added the break right? Added it and set it to 99.
Annnnd same thing, only this time the debug prompt shows it stopping at 98.
It never actually exits the loop.
Any thoughts?

More weird behavior.
So the original version of the loop looked like this:


*HOWEVER* if I uncomment the upper whileindex=whileindex + 1 variable... it works. Or rather, the 'do stuff' portion works and you don't get completely locked up. BUT - it never actually exits the loop in the proper sense. it just stays at 99 forever and never leaves. This is all handled by a trigger 'player in zone' main script.

I feel like this is some kind of game-guru lua nuance I'm not familiar with and if I just knew what it was, I'd have it. Anyways, that should cover it for now. Thanks for any thoughts/comments.

In a year of Lua scripting I don't think I've used a while loop!

I would suggest making whileindex local as a start but I'll play around later to see if I can replicate your issues.

thanks. I suppose maybe it's calling it over and over because it's in a trigger box, so localizing might help - will let you know.

Ahh, I see the problem, the Prompt is only showing the last value, it isn't getting stuck in the loop it is just executing the whole loop every frame but you will only see the final value in the Prompt output.

If you use a while you are literally stuck inside it until it completes, there's no sync or update to the engine etc in that cycle so it will just appear locked up if the while never completes or takes too long.

Amen is right that it will only prompt the final value because as I say, there's nothing in there to tell it how to display that prompt (the engine handles all syncing behind the scenes normally).

With the above limit and as scripts are called every frame its not generally a good idea to call while or repeat until (unless for very quick things you're sure will exit) as this will result in hang ups or even full lock up (in appearance at least).

What exactly are you trying to do? I'm sure it can be achieved with a different method.

I'll send you a PM smallg.
