AI: (Get Well Soon Bero!)

[Clai]

did i mention that dantarion has the atkd files documented already

http://spreadsheets.google.com/pub?key=t4rs0MkPoOH2VwJVQjoIyRQ&output=html

we need to get the data categories documented before we move on to something else. we also need to stop randomly filling large ranges of data with random numbers. it doesnt accomplish anything

If I knew how to edit specific parts of data to reach a conclusion, I would, but I don't understand what the numbers are supposed to signify, so I'm doing all that I know how to do and changing the entire data file to see what general behaviors the CPU's exhibit. I took a look at dantarion's document, but from the looks of it, the data sheet seems to be a compilation of how the moves themselves work, but not how the CPU determines when to use said moves.

One thing from the past session I was really interested in is the test where Jab3 was substituted with taunt and when the CPU was tested, it would often do jab1-jab2 but never use jab3. If the CPU really uses a roulette wheel to choose what action to take, we can find a way to assign very low values to moves that we don't want the CPU's to be using so that the CPU will have a higher chance of using good moves and a lower chance of using bad moves. It appears that we won't be able to do that, though, until we document the data as you said.

If I haven't already said this before, I'll acknowledge now that I know next to nothing about manipulating the data we have. I've been trying to teach myself about this, but without the knowledge to constructively tinker with the data, I can't accomplish much. I do want to move this project forward, though, so helping out would be much appreciated.

Looks like documenting the data seems to be our top priority now. Everyone is welcome to help out with this, but if anyone is kind enough to lead me in the right direction to contribute to this myself, I would be incredibly grateful.

 

[Bero]

Thanks to Dantarion's document. I could add support for ATKD to BrawlLib.

When you open ai_character, you can see Subaction ID ,Unknown value*3,X Min Range,X Max Range,Y Min Range,Y Max Range

 

[Dantarion]

I figured out all the values already.
I dont remember specifics, but it has to do with which frames of the move are considered "dangerous"

In that link, short 2 is always 0.
short 3 is the frame to start dodging
short 4 is the same to stop dodging.

Think of the range numbers as creating a "Box" of danger.
I made a youtube video about this somewhere...


PS. Changing things randomly isn't going to help, but at least you found what affects what. Remember. A lof of the AI is shared, meaning we won't be able to edit it inside a characters files. However, recovery is one place where the AI has to have some kind of logic to decide what to do.

I haven't looked at any of those files.

 

[Bero]

...So, do we have to consider how to edit ai_common that is in Fighter.pac?

 

[Clai]

...So, do we have to consider how to edit ai_common that is in Fighter.pac?

Yes, we will have to consider the ai_common as well. Changing values in there will change the behavior of all the CPU's instead of a particular character. If we're fortunate/determined, we can find and change some common traits like air-dodging after being hit all the time.

The last MiscData[0] file appears to contain the data that the CPU needs to analyze its 'danger' zone and determine its course of action. At the very bottom of the file, after subtracting all the filler, the text in the file comes to this:

#full_f
#key_f
(#full_f.#range_chk_f
#jump_start_f.#meteo_range.#atk_range_base.#atk_range_rnd.#quick_range1.#quick_range2.#dash_range
#key_f
(#full_f.#range_chk_f
#range_chk_f
(#full_f.#edge_range
&#wait.#edge_range
#hi_base
#wait_f
(#full_f.#edge_range
(#full_f.#range_chk_f

Changing these values will change how the CPU will perceive attacing ranges, running ranges, edge ranges, etc. Documenting this would be a godsend.

 

[Dantarion]

So yeah, get on that.

i demand you do work, get at it!

And by do work, I mean help with PM.

thanks

 

[Bero]

Do you mean making ATKD editable?
If so, I can do it in five minutes.

 

[Dantarion]

No, I mean getting the first of the AI files decoded.


Its gonna be hard without USBGecko to poke and and test things out.

 

[Bero]

Oh, that work seems to be yours.
But if my USBGecko is fine, I will try it.

 

[Dantarion]

Search for where a characters AI file is held in memory, then set read breakpoints and ****

 

[Bero]

I see
Low-level language always makes me confused but I'll do my best(I'm not sure if I try that though)

 

[Masky]

..........

 

[Bero]

Original post had mistakes so many that I deleted it.

EDIT
MiscData's header contains address of entry and strings.

EDIT2
Each entry has header. It contains unknown(4Byte),type(4Byte),entry part2 offset(in other words entry part1 size, 4Byte),unknown2(4Byte)

EDIT3
Completing second MiscData[0] seems not to be so hard, so I will be glad if someone tries to analyze AIPD file.

EDIT4
Finished analyzing each Offensive AI Entry. I may be able to add support of it BrawlLib.

 

[leafbarrett]

The game froze when Fox threw Ganon offstage, but before that the CPU looked promising with its defensive play. I'm going to test this further and see if this test was just an anomaly or if something in the data freezes the game.

It's not an isolated event. I tried it, and it happened to me too.

 

[Bero]

I almost finished second AI data.

First, MiscData has some AI entries.
The characters seems to override AI entry in ai_common with their own AI entry. Each AI entry has an ID and ai_common has most entries that has same IDs. And they are very similar each other, but different a bit.

Second, AI entry has AI events. they are consists of type, number of entries, its own size, entries. Sometimes AI event has nothing but type and size. This means type itself has something important meaning. ...Oh limit word..

 

[Bero]

Sorry for double post but I'm writing this on PSP.

Well, we will have to make a thread about AI type,etc if we finish analyzing AI.

At the end, I haven't finished understanding words that are bottom in the file like "#wait_f" "#key_f". If there is someone who found a rule of their order, please tell me.

What exactly do you mean by AI type? Do you mean specific behaviors of the CPU, do you mean types of files, do you mean specific characters, what kind of new threads would we be making?

 

[Bero]

We don't need a new thread now. It will be needed if we completed AI. (or reuse this thread?)

I can't explain well about AI entries, AI events, so I will send you modded BrawlBox that can open second AI data. You will be able to understand in that way.

 

[Bero]

Finished analyzing second MiscData. So, I show you the steps from now to custom AI.

Step1 Analyze AIPD file and make it editable. (each character's AI is editable in this step.)

Step2 Analyze another two MiscData in ai_common.pac. This will be done soon.

Step3 Consider about each value's meaning. This will be a hardest part. This can be done by people that have no programming knowledge because replace, edit, insert, deleting each entry will be made easier until that time.

 

[Dantarion]

Bero, if you can write something that describes how to read those files, I can dump it to a spreadsheet for all characters.

BrawlBox with OAI minor support

@Dantarion
I've waited for you.
Dumps will be useful in Step3! But I can't describe them well, so I show you some source codes. The man who can understand Kryal's code will be able to understand this.

unsafe struct OAIHeader//stands for offensive AI header
    {
        public bint _unk1;
        public bint _numEntries;//number of offsets
        public bint _unk2;//0x1
        public bint _unk3;

        public VoidPtr Address { get { fixed (void* ptr = &this)return ptr; } }
        public bint* entryOffsets { get { return (bint*)(Address+0x10); } }//contains entry offset. each offset is distance from Address
        public bint* stringOffsets { get { return (bint*)Address + 0x10 * _numEntries; } }//contains string offset but there seems to be other entries on that address
    }

    [StructLayout(LayoutKind.Sequential, Pack = 1)]
    unsafe struct OAIEntry
    {
        public bint _ID;
        public bint _EventsOffset;
        public bint _part2Offset;
        public bint _unknown;

        public VoidPtr Address { get { fixed (void* ptr = &this)return ptr; } }
        public VoidPtr Event { get { return (Address + _EventsOffset); } }
        public bfloat* part2 { get { return (bfloat*)(Address + _part2Offset); } }
    }

    public unsafe struct OAIEvent
    {
        public sbyte _type;
        public sbyte _numEntries;//sometimes, it is 0
        public bshort _entrySize;

        public VoidPtr Address { get { fixed (void* ptr = &this)return ptr; } }
        public bint* Entries { get { return (bint*)(Address + 0x4); } }
    }

    public unsafe struct OAIString
    {
        public bint _numEntries;
        public bint _unk1;
        public bint _unk2;
        public bint _unk3;

        public VoidPtr Address { get { fixed(void* ptr=&this)return ptr;} }
        public bint* Entries { get { return (bint*)(Address + 0x10); } }// each entry is 8Byte
        public VoidPtr StringAddress { get { return (Address + 0x10 + 0x8 * _numEntries)
    }

for example, these are captain falcon's data

0x00-0x0F OAIHeader
0x10-0x1F Offsets of OAIEntry
0x20-0x2F OAIEntry1
0x30-0x88F OAIEvents1
0x890-0x913 Floating points1
0x920-0x92F OAIEntry2
0x930-0x1213 Floating points2
0x1220-0x12CF OAIString

 

[Dantarion]

http://www.mediafire.com/?qhtywulioyr

Should be useful.
Python script for working with this dump coming soon.

 

[Bero]

I've just started looking into AIPD.
0x10-0x16F are Floating points, right? And 0x170-0x263 are entry offsets from beginning of the file.
But there seems no rules of each entry size.

EDIT
There seems to be some integer points. I continue to analyze aipd using USB Gecko.

EDIT2
I found OAI parser routine.

 

[Bero]

Note:
Entry types of AIMain may be able to be categorized.
・Reserved words: Type0,Type4,Type8,Type9,Type21,Type30,Type32
Also, numbers of Type6 and Type9 are almost same. And Type6 is always before Type9.
I think this means Type6 is sign of "Begin block" and Type9 is "End block". I don't know what block it is though.

 

[Clai]

I want to take this opportunity to say thanks again to everyone who is continuing to work on this process and I apologize if my inaction is causing any problems. Due to lack of coding knowledge on my part, I'm essentially useless when it comes to information like this, but if there is anything specific you want me to test that you cannot on your own, I would be more than happy to help out.

Again, thank you very much for doing this and I hope that whatever you guys are doing can lead to results.

 

[Dantarion]

Me and Bero are probably gonna finish this...eventually.
The files seem so bizzare.

 

[Life]

Once I get my SD card reader back I might try to mess around with this. IDK.

 

[Bero]

@Dantarion
What are you saying? This is my only reason that I haven't quit SSBB hack.
At least, I will find command input type.

Looking into this by using USB Gecko is IMPOSSIBLE. All we need is collaboration. First, it will help us to make AIMain that contains only one entry(like Type1,Type2,Type3...) and replace all other AIMain.
I added automatic replacer to BrawlBox Modset3.2. This helps you to replace all entries.

I did that using Type1 and Type6. Type6 froze the game, but Type1 caused this

 

[Bero]

What makes me wonder is there are few people that think Bero is a programmer and one of the active SSBB hacker.
This also makes me feel that I'm not needed.

 

[Eldiran]

Don't be disheartened Bero. It's more about who's been around longer, and been more in the public eye. I'm not actually a programmer on the level of Dantarion -- I'm only good with PSA when it comes to Brawl. (I am flattered though aanssell25.) You're way better at this stuff than I am.

Honestly, you and Dantarion are the only two people I know of who are actively making progress in hacking new areas of Brawl. You're the 2nd most knowledgable person around when it comes to Brawl hacking.

 

[[TSON]]

Eldiran, you're talking to a bot that quoted the first post in this topic XD.

And Bero, you are needed. Very much so.

 

[Bero]

Haha, sorry guys. I was too sentimental.

 

[rPSIvysaur]

Bero, you have no idea how much we appreciate the work you are doing.

 

[Eldiran]

The sig should have tipped me off... I am flattered nonetheless that mindless AI think I am a good programmer

 

[Bero]

So, there are still people that are interested in AI, right?
I'm relieved.

 

[Life]

Bero, I also would like to thank you for your work. (Your English is great!)

I'm currently just kind of playing around with stuff in these files, will edit this post if I find out anything.

Right now, I'm going to deal with #dash_range and set the values associated with it to zero and something massive and see what happens.

I have also expressed my thanks for your efforts in this, Bero. You were one of the first people to get into this project and thus you couldn't have more of a pivotal role.

However... your video contains a malformed ID. You might want to look into fixing that

 

[Bero]

http://www.youtube.com/watch?v=cZV80r9yclo
Fixed.

Well, you guys don't know what Dantarion and I were doing. So, I explain that from now.
AI is consisted of AIPD,AIMain,ATKD.
・AIPD has been analyzed but we don't know how to use this.
・AIMain is main file of AI. This includes condition evaluation,command input and more. Each AIMain files have their own ID. ID and its usage list has been completed by Dantarion.
20 - Get on same platform
40 - Walk up to you
50 - Jump!
60 - Dash up to you
70 - Shield+Roll
80 - Gets on the other side of you
1010 - Stick toward?(Meta used Down b to approach with this)
1020 - Stick toward
1030 - Stick towards (Did not change platforms)
1040 - Stand still (Meta used Side B though)
1050 - Get on same platform (Olimar did NOT do this)
1060 - Same platform or under(Olimar went under)
1070 - Jump repeatedly (No R or L, just double jumping till out of jumps)
1080 - Same platform, or DIRECTLY UNDER (Olimar still didn't want to jump. INSANE perfect dashdance on either side of target)
1090 - Same as above?
10A0 - Character specific stuff
10D0 - Nothing?
1120
1130 - Marth did netral B offstage with this?
1140 - Follow Offstage (For edgeguarding?)
1160 - MK spammed down b
1170 - Follow to end of ledge? (For edgeguarding?)
2010 - Jump Recovery (Edge)
2020 - Side+B Recovery [All Chars]
2030 - Jump Recovery (Land on Stage)
2040 - Recovery [Character Specific]
3020 - Premptive Shield?
3090 - Walk in range?(Not too close though)
30A0 - Spotdodge
30B0 - Dodge when attacked
30D0 - Airdodge when attacked
6030 - Rapid Attack
6040 - Attack
So, we should look into this first. This is the most important file of three.
・ATKD is a file to be used by the game to know opponent's attack. This was entirely analyzed by Dantarion.

I added BrawlBox feature that allows us to edit AIfiles. All we need to do is finding the way to poke them.

...Well, I explain AIMain file from now.
AIMain file was called "CE" on BrawlBox screen.(I thought it was only condition evaluation, but they contain many elements. So, I changed their name into "AIMain". This will be reflected in next Modset.)
AIMain has many Type** entries. They have their own meanings such as "If","Endif","Input Command".
Sometimes, they have variables of float or integer. But like Type4 or Type9 or so, there are types that always have no variables. I think they are "reserved words"(please google it). Because of these things, I think I can categorize them.
1 Call function
2 Reserved words
3 Command input

*sigh* So, to look into AIMain, replacing all AIMain entries into one of them is make it easy.
Dantarion did it using codes. http://www.youtube.com/watch?v=8rFnjqzXrxo
But you don't have to make any codes. Open your AI file and right click on "Events" in "CE**". Select "Auto replacer", choose your AIMain entry file. BrawlBox will automatically replace all entries into selected file.
I think we can look into meanings of types in each AIMain entries by making AIMain entry which has only one entry.

If you can't understand what I said, please ask me questions.

 

[humble]

Bero...That is awesome! Thanks for all the info! I'll be reading this over to understand again, but this is really cool!
