Memory Leaks with a lot of String variables?

My latest project uses a dialog system that works like this:

1 string, contains the lines for what a unit is going to say.

The String is defined when the game starts in an array, where all my dialogs are stored as well. One NPC might have 5 or 6 strings that belong to him.

When you speak to the proper NPC, it parses the one string and splits it up into another array, one variable for each LINE. It knows when to find another line because I have the end of the would-be line marked with a |.

Then, once all that is set up, It turns on a 0.03 second period event trigger that generates a 1 letter at a time effect. The text is displayed in a multiboard that shrinks and grows depending on how large the data is. This works beautifully, but it leaks a LOT of memory. First off, since i'm a novice in memory leak detection, can anyone point out some obvious leaks or perhaps show me a way to do this without it leaking like an SOB? I DONT use local variables, but perhaps I should start, because I really want to use this system but not if it's going ot leak memory the way it is. I don't really know how, as up until now I haven't had much of a use for JASS since GUI was functional enough.

Anyway, here i've posted the two triggers, they're kinda long.






Here is the Letter Server trigger:

I'm pretty sure this doesn't leak. What led you to believe it leaked?

I think it's very possible it lags, but before dealing with that I'd like to find out why you thought it leaked in the first place.

This thread is where I first went to read about leaks, and Cubasis mentions a very key point: strings don't leak memory (and neither do integers).

So, does it leak, or just lag?

When I watch the mem usage of wc3.exe, it jumps up fast when i am talking to my NPC's. It goes up at a rate of about a meg a minute or so. It really don't lag at all, i'm just worried about it becoming unplayable after awhile.

Example: When my War3 just started up, it's mem usage is 149,556k. Now, i'll run through all my dialogs(note, all my NPC's are the in same place so it's not like it has to load other parts of the map into memory, etc).: New mem usage: 162, 428k. This is after running through all my dialogs. I thought maybe something else I was doing was causing it, but when I just let the game sit there it doesn't really leak any memory at all.

I have a gig of ram so this doesn't lag me at all, but i'm worried about other people lagging because if I put in all the dialogs I want, it would probably leak to upwards of 300,000k or more.

Thanks for looking at it for me.

That answers your question. The way WC3 handles string variables causes this issue, it seems.

Wow, good find Legolas. That thread details your problem pretty well. I also didn't know that, so good info.

That really effing sucks if that's the case. Thanks for pointing that out. I guess I'll have to make my dialogs a lot simpler or begin to petition blizzard for a fix.
