Posted 22 July 2010 - 08:30 AM

This thread is an attempt to compile solutions to most common problems with AIs for ragnarok online, both those which can happen to all users, and those which are specific to users running Windows Vista. I'll be refining and improving this as time goes on.

THE MAJORITY OF AI PROBLEMS WITH AI ENCOUNTERED ON WINDOWS VISTA/7 ARE CAUSED BY UAC.
IF YOU ARE HAVING AI PROBLEMS UNDER VISTA/7, READ THE FIRST ENTRY UNDER VISTA-RELATED PROBLEMS BEFORE POSTING.


ALL PLATFORMS:

Problem: Receive message "cannot read .\AI\AI.lua. there is no such directory or file" when attempting to use homun, or "cannot read .\AI\AI_M.lua. there is no such directory or file" when attempting to use merc.

Solution: Your default RO AI is missing or has become corrupted, OR you're having Vista/Win7 UAC problems (See below section)
Download the basic AI from here: http://downloads.iro.../Default AI.zip
extract it, and copy the following files from the AI folder in the downloaded default AI into your AI folder:
AI.lua
AI_M.lua
Const.lua
Util.lua

Problem: Receive error messages upon attempting to use custom AI in game, but not an error referring to callback.lua. If you are running vista or windows 7, and the AI is installed correctly, see the problem in vista section.

Solution: The custom AI is not installed correctly, or was supplied in a non-working form by the author of the AI.
Ensure that you have the lua files inside the USER_AI folder, not inside a folder within the USER_AI folder.
Your AI and USER_AI folders should look something like this:



Problem: Receive error message(s) when attempting to use custom AI configuration program.

Solution: If the error messages refer to .Net, VB, or runtime, or specify a missing .dll file, you are missing a required runtime library.
The AzzyAI control panel requires the microsoft .Net framework, available at:
http://msdn.microsof...k/bb264589.aspx
Other AI control panels may require the same runtime libraries, or a different one - review documentation or contact the author of your AI.

VISTA/7 SPECIFIC PROBLEMS:

These usually occur under Windows Vista and Windows 7, when User Account Control is enabled and RO is installed to the default installation location, C:\Program Files\Gravity\Ragnarok Online.

Problem: Custom AI is installed properIy, but still behaves as if it was the default AI. No amount of changes made in the USER_AI folder seem to effect AI behavior.

Problem: Receive error "./AI/USER_AI/AI.lua:3: could not load package './AI/USER_AI/callback.lua' "

Problem: AI is installed correctly, and is working, however, no amount of changes made using the GUI effect the behavior in game. Making changes directly to the config files may or may not work. Or, AI is installed correctly and working, and changes made using the GUI effect the behavior in game, but manually changing the config files does not change the behavior of the AI.

Problem: Receive error "cannot read .\AI\AI.lua. there is no such directory or file" or "cannot read .\AI\AI_M.lua. there is no such directory or file", however, AI.lua and AI_M.lua exist in the AI folder.

Explanation: Vista and windows 7 place special protections on the program files folder (and all subfolders) as part of the User Account Control (UAC) functionality. Vista/7, with UAC enabled (the default setting), changes made by programs (instead of the user) will be made to a virtualized directory ("UAC Virtualization") within the user space, even if the program has permissions to write to program files.

Some versions of the client came with a defective AI which produces the callback.lua error - in this case, the defective file will be the one that gets preserved by vista's stupidity.

Because of these protections, settings saved by the GUI can be piped to the virtualized directory while the game is looking at the non-virtualized directory, or vise-versa.

Solution 1: Move the ragnarok online folder to another location on the C: drive - i recommend making a folder C:\Games\Ragnarok . Delete the AI folder and restore the default AI from the link above. Reinstall the AI.
Solution 1b: Failing that (it is quite possible that just moving RO will not work), uninstall RO, and reinstall it to C:\Games\Ragnarok.

Solution 2: Disable UAC (User Account Control).
http://www.howtogeek...er-account-c...
You may have to delete the USER_AI folder, and then make a new USER_AI folder, and install the AI into that.


Problem:
AI Configuration program for MirAI or AzzyAI gives an error message, saying that files cannot be found, or that access to files was denied.

Solution:
The AI configuration program must be run as administrator. This may not be necessary if UAC is disabled.


AI BEHAVIOR PROBLEMS:

Problem:
AI generally, with some features working and others not (AI is definitely custom AI, but not doing what it should) after switching from another AI.

Solution:
Delete all files in the USER_AI folder, including those from any previous AI's used, and reinstall the AI. Simply copying all the files for the new AI over the old ones should work, but i keep getting reports contrary to this. May be a vista/7 related issue.

Problem:
Tactics or monster specific behavior does not work for mercenaries.

Solution:
The client does not provide the facilities for mercenaries to identify different kinds of monsters. Some AIs, including AzzyAI, can differentiate between "natural" monsters and those summoned by some unnatural effect (mobs summoned by other monsters, alchemist flora and plant cultivation. Some AIs also attempt to detect 'herb plants' in order to avoid wasting time attacking them.
AzzyAI supports a very awkward workaround as described here: http://forums.playra...w.asp?tid=15857

Problem:
Mercenary bugs out after using bowling bash.

Solution:
This was a bug that occurred with version 1.27-1.281 of AzzyAI. Upgrade to 1.282 or later.

Problem:
After teleporting, player is sometimes disconnected.
Upon reconnecting, the mercenary immediately leaves.

Explanation:
Mercenary Actor ID's change every time they spawn (which occurs on teleports and map changes).
Because the Actor ID is a part of the packets sent by the client to control the mercenary, latency can result in the following problem:
If a player teleports, and the merc attempts to do something before the server receives the teleport packet, it is possible for the player to have teleported (giving the merc a new Actor ID) before the server receives the "merc do-something" packet sent before teleporting. This packet will refer to an incorrect Actor ID. Since it is not supposed to be possible for the client to send such a packet, the server assumes that the player is using an illegal client or AI and punitively disconnects them and ends the mercenary contract.

Solution:
Don't teleport while lagging if you are using a mercenary, or put the mercenary into standby before teleporting. Yes, we all know this is a major hardship, but that's what happens when the developers try to "punish" players for doing something that should be impossible (ex: DC on moving while talking to npc, AV bug, etc). It is also worth noting that even when lagging, most players will not encounter this bug.

Nope, it's just that my AI is SOOOO good, and this info section SOOOO AMAZINGLY COMPLETE that everyone just reads them and is like "Oh, cool, it works now" or "Oh, wow, AzzyAI is so awesome it knocked my socks off! But that's okay, because my merc/homun will level me while I go find my socks"

But seriously, yeah, we need more registrations :-(

I'm curious about something. Has anybody on vista tried keeping UAC enabled, installing to Program Files, setting ragnarok.exe and all other applicable executables to run as administrator, AND setting full control of the Gravity folder to the user account? By doing these things I have never, ever had any problems with my Program Files folder or any games I had installed there. Disabling UAC can stop programs from writing to an alternate directory and into the Program Files folder, which of course means it can no longer find your saved settings since the little "detour" is gone. Disabling UAC should NEVER be an option. I'm not sure if either service pack alters this in any noticeable way.

I'm surprised Microsoft released Vista without an easier option other than right clicking everything and manually changing the properties. :mellow:

I havn't tried that - i don't use any systems with UAC. All my systems are on XP, because vista/7's user interface is insufferable and UAC prevents everything I want to use from working.

Jasmer, I run Ragnarok and Azzy's AI on two win7-32 boxes with UAC enabled and with no problems with the AI or updating.

Ragnarok.exe, RagnarokFree.exe, Azzy's Config gui app, and setup.exe are given "run as administrator" flags.
Ragnarok.exe & RagnarokFree.exe are given "run in compatibility mode for xp3" flags
The user playing is added specifically and given "full control" to "C:\Program Files\Gravity" for "this folder, subfolders, and all files"
The "Replace all child objects..." flag is set after the permission changes are done to insure correct propagation to all subfolders and files.

NOTE: While I do not typically use deny entries, If you have any in effect you will need to make sure they are not in effect for the user or any group that user is in with relation to "C:\Program Files\Gravity".

See that's what I thought. It's a bit complicated, but running ANY program through program files on vista/7 with UAC and no problems IS possible.

Restore to the default configuration (H_Config and H_Tactics supplied in the download). I don't remember what caused that issue, but unless something was changed by gravity, it does not happen in the default configuration.

I got the same problem like mentioned above ( Vani is acting weird), it started to happen when I updated your AI from 1.28 ( something that I had ) to your latest version. It keeps mobbing crap also while the merc AI is working fine, the Vani doesnt use any skils and it seems like it's not different at all from the standard AI. I use WinXP btw.

I have not been able to reproduce that behavior, and I don't have time to research what might have caused it (10 million things to do, including getting 1.35 working, which currently has a serious showstopper bug that is behaving in ways that defy any logical explaination).

See if there's anything on it in this thread:
http://forums.playra...sts=168&start=1

Also, since this issue is specific to my AI, we should take it to the AzzyAI thread, as this is for general AI troubleshooting.

Azzy, that link is outdated and gets redirected to a list of subforums. If you find time between your 10-million things-to-do (I know how that is, trust me), be sure to update that bit. And if you feel like it, you can mention that RAIL also has a similar, compatible workaround.

Hey Azzy! I Just want to thank you for this awesome AI. I just started playing around with the way my Amitsir reacts to certain monsters and now I'm getting an AI.lua error that i just can't figure out.

I've set it to Tank poporings and Marins and when i come on to the map with them I get -

"./AI/User/ai_Main.lua:1019 attempt to compare number with nil"

I just got this in a popup when checking the tactics tab:

I'm checking tank behavior today, it is broken in dev 20 (and as far as I can tell must have been broken for ages, as i've done nothing to change it). Error is due to existing issues with tanking that are already being worked on.

Bug reports on the GUI are not being accepted, GUI is being rewritten for 1.50. That version of the GUI is all there will be for 1.40.

Please ensure that you are running the latest 1.4x version (ie, 1.41) not one of the earlier versions of 1.4x (either 1.40 dev or 1.40 final); I know several of those versions would crash when used with any mercenary - so make sure you are running 1.41 (check AAIStartM.txt or AAIStartH.txt in your RO folder to check what version of AzzyAI you are running).

Baph Jr's are not recognized by the AI, so skill autocasts likely won't work, however, the AI should not give any error.

If you are still getting errors, please post the exact text of the error message you receive so that I can provide assistance with the crash.



I would like to add support for Bapho Jr, but I don't have access to any of the scrolls (don't even recall where you get them from), so I need the following information in order to add support for them to AzzyAI:
Max HP, Max SP of Baph Jr mercenary before it's gotten enough kills to do the HP UP or SP UP skills.
List of skills and levels of the skill that the Baph Jr has.

Thanks


The obstacle avoidance cant-happen messages in AAI_Warn.txt are spurious warnings, they can be disregarded (and are not written in 1.50 - but don't upgrade to 1.50 yet). The whole obstacle avoidance system was implemented intricately, and then I discovered that GetV(V_MOTION,id) doesn't work as advertised, and had to scrap most of it, and the situation where that message is logged ceased to be a can't-happen, but I hadn't noticed that until later.

HI Dr azzi,

I don tknow whether its my computer or what, but my Sera (vani) always freezes and don't move? Don't notice the problem with my dieter (amistr) as yet....... i leveling in od2 and whenever try to afk overnight, i end up dying not because because my Sera stops attacking suddenly and just hangs there. I've caught this happening when i'm not afk and when I manually command it to attack again, everythign will work fine again. I've tried uninstalling and reinstalling it but it keeps happening.

Is something wrong with my AI or just my computer?

Thanks so much again

If you mean the issue where it's hanging in a flinch motion, this issue effects all homuns, particularly at low levels. It happens when they are hit at a certain point in time when casting a pre-homun-S skill, causing them to hang in the flinch animation. This is a game bug and is not an AI issue.

If it's hanging and isn't in a flinch motion, it's an AI issue. If you're using AzzyAI, make sure you're using the latest version, and take a traceai and send it to me along with AAIStartH.txt and AAI_ERROR.log (if present) in your RO folder.

Why did you replace the default ai with the pre 9/4 version from wiki that is incompatible with current client? Error is coming from when it tries to load default ai but can't because it loads external files wrong. You need the new default ai.

http://drazzy.com/ai/default that has packages of default ai, and default ai+AzzyAI

Your default AI looks like the pre 9/4 one

 

Download and install either:

 

Default AI - http://drazzy.com/ai...-4DefaultAI.zip

 

Default AI + AzzyAI 1.541 preinstalled http://drazzy.com/ai...AzzyAI_1541.zip
