Still no luck finding the problem, but I did get an "object variable or with variable not set" error when quitting the game. This could be due to new additions not working, since I started adding more graphics and maps, but maybe it's related to the same problem I've been having. I got the error while running the exe, I've never gotten it while running the ide, so no idea where its going wrong. Any ideas?

Edit: still always has the body right, but all other variables after it (body is the first one received) are 0.

I've still been working on this day and night, and here's what I've come up with:

There were two bugs I had, and since I fixed them both I'm not sure which one was causing the charindex = 0, or even if the charindex = 0 is really fixed, since it could still pop up randomly. But at least in the last 3 days of testing, I haven't encountered the error.

The first error was with grhindex, which was working fine most of the time, but going crazy every once in awhile. This is undoubtedly because I switched to extended item descriptions like in plagued dead, and missed adding something. I figured that plagued dead uses the alternate rendering system for layers, so there must be some parts that are incompatible with my code (I use the default rendering) when rendering the graphics. I stopped using the udtobjdata grhindex required for extended item descriptions, and just sent grhindex the old way. I still use extended item descriptions client side from a binary file, only the grhindex gets sent the old way. This fixed the problem up.

Next up I had another problem, a packet problem, involving quests. I've been using a much larger version of the quest log window, which big detailed descriptions for quests (about half a page of text sometimes). Well if you happened to have 4 or more of the quests with long descriptions (some short description quests you could have more of) in your current quest list, the buffer would overflow and give you some weird errors (all stats would be equal to zero, including level and class, but only on client side.) This error would only occur when you log in, when the server sends the quest descriptions. I can only assume that these long strings were too much for the buffer when all being sent at once, because canceling any of the quests fixes it. Anyone else using long quest descriptions should look out for this as well, since it isn't really unique to my code. Solutions are to either limit number of active quests allowed to a small enough amount that it won't overflow, shorten descriptions, or if you don't want to sacrifice functionality you could store the descriptions in an encrypted file client side.

My question is how much can the buffer handle? There was technically nothing wrong with my packets, they were being sent correctly and unchanged from the original code with vbgore. Is there a maximum size the buffer can handle, or anything like that? Or is there, despite the apparent link to quest descriptions (which changing, solved the problem), something else wrong somewhere in my packets?


Edit: Charindex = 0 error STILL happens. Happened again twice when changing to the same large map with lots of npcs, the map it almost always happened on in the past.

In SVO we have a problem with the /me packets. There was an error like this I had, but I just did a If CharIndex = 0 Then Exit Sub. Different errors still pop up in different places (E.g. map music / weather / version randomly changing)

The /me packets all seem to be send fine though, but it IS /me which causes it on ours.

Hmm, I'll take a look at that and see if its causing it for me as well. I haven't changed any of the code there though, what about you?

I did try adding if charindex = 0 then exit sub, but in my experience it leads to the server telling the client something happened with the charindex, and the client, not having the charindex at all, gets even more screwed up. When I had the exit sub in there, I was getting all kinds of other errors too, so that might explain those map/weather type errors your having. Anyway I'll take a look at /me and see if its causing my problem too. Good to know I'm not alone at least!

Note: does it also happen in SVO when you change to a map with a lot of NPC's, or does it just happen randomly?

It seems to happen randomly, but I'm pretty sure it's /me causing it for us, but I havn't touched the code for /me and it looks relatively right

i use to have this issue but im not sure if i still have it. This happened to me wen i had a lot of summons and changing maps. I havent seen this problem for a long time. I reckon its a packet issue from your MakeChar sub on your server.

The post was like one month ago, then i think it's already solved!
But... why not put this code on the part of code that teleport the user? The very first part:

Then if the char don't have charindex, he can't teleport, buf if it's a "bad sent" packet, if put this code on some critical places of the code? (the teleporting part):


I don't tested it, and i think it will not work, and it's a little "cheap hack"... but.. maybe o.o'...
Sorry for the poor english!

That wouldn't work, it would just make the client ignore the fact that its missing information, and cause things to get much worse. Bugs and errors will seem to pop up randomly in different spots, ending in a crash anyway.

As for the attempt to find a new charindex...I don't think the code you put makes sense, but I think you meant to have it search for an empty charindex and just assign that one. Unfortunately, that would just mean the client and server have a different charindex for the same character, which would lead to massive problems and crashes.

ok guys. what if charindex can be 0. Somewhere the server sets it up. perhaps this is happening with large numbers of npcs on a map? Look for anything fishy like 1 to lastchar and see if the server might actualy be sending charindex 0 but the client doesn't like it becuse the array is starting at 1.

It may be that, Richard. My players get it on login, and the first map has probably 50 NPCs on it.

If Richard's theory is correct then an easy fix for it will be adding

at the start of every sub containing For X = 1 to LastUser on the server would fix the client rejecting CharIndex = 0 because the client would never receive it.

EDIT: Those getting object variable or with variable not set RTE is that your UserIndex is invaild. In other words it = 0 or the user is not completly logged in then disconnects. So just make an easy check to stop this crashing your server.

Wouldn't it be an error in Server_NextOpenCharIndex()? It has to be that or Data_User_MakeChar(). My players get the error on character creation, granted the first map has around 50 NPCs on it plus the other players.

Does ur subs have a check for if the user is disconnecting?
Because after a new user is created the server sets

You can have a double check just in case with UserList(UserIndex).Flags.Disconnecting

Anyone fix the bug?

I'm still having this bug over a year later.
