AI INSANE + XOI

Fri, 30 Oct 2026 21:06:16 +0100

The original Little Fighter 2 has four computer levels: Easy, Normal, Difficult and CRAZY!. Its computer player is a set of rules written for the original fighters, keyed by their ids. Put it in a mod (One Piece GrandWorld, Naruto: The Setting Dawn, KT-LF2, Sx2…) and it has no idea what the new moves are, so it mostly punches, kicks and throws the odd D+A at random.

INSANE! is a fifth level, selected right after CRAZY! on the character selection screen (and in Tournament and Battle mode). It contains no line about Luffy or Naruto: everything it knows about a fighter comes from playing each of that fighter's moves itself, in a private copy of the match, before the match begins. That is why it can use the moves of mods nobody has ever written an AI for.

I have developed an entirely new version of an AI capable of self-learning; it can recognize its own skills and utilize them appropriately. Furthermore, it can scan and anticipate the enemy's incoming moves within a 16-frame window, allowing it to adapt dynamically. It is not yet complete, however; I am currently expanding the AI’s awareness to include the opponent's capabilities, which will enable it to respond even more effectively. I am currently continuing to refine how the AI perceives information about its opponents, with the goal of making it increasingly sophisticated. Developers are welcome to access my open-source code to contribute further—this AI script is designed to be compatible with almost any mod (I have successfully tested it with about six different mods, and it works well).

New AI model, which I’ve named "XOI." Its learning mechanism is similar to the SPSA (Simultaneous Perturbation Stochastic Approximation) method used in world-class chess AIs. It has proven highly effective; in tests conducted using the "KT" and "HELL" mods for the game *Little Fighter 2* (LF2), it achieved a 65.4% win rate against the "INSANE" difficulty AI (in the HELL mod) across 45,120 test matches, and a 54.9% win rate (in the KT mod) across 20,358 test matches.

[Ver 2.5] Programmable AI via Scripting

Sun, 26 Nov 2023 06:05:56 +0100

Programmable AI

"Am i allowed to post this thread?"

Disclaimer: This is just a.. fork?.. of "[2.2] Programmable AI via scripting" and "Github repository, made some minor improvements" thread.
This tool/ddraw are massively or originally made by;
• Doix    |
• Som1Lse |
• zort       | About zort
• Luigi600  | for neora compatibility
• and everyone else who have an effort in it.

DDraw Source : GitHub.

Version 2.5 (Click to View)

Version 2.4 (Click to View)

I just want to make some changes, like adding something that's missing; background's layer, weapon_strength, etc.

Changelog ;
• Update the AngelScript version to the newer one (v2.36.1).
• Rewrite some part... actually almost every part.
• Fixed "ccatcher" and "ctimer" offset, new offset "ccatching" replacing the "ccatcher" offset.
• Remove some unused part.
• Added new offset "heal" with "game.objects[].heal".
• Added new global object "version" to help determine the version within the script.
• Added illegal input protection. (does not work 100% with "int ego()")
• Added special feature;
You can have "ai.as" in "ai/" folder, and the script will be used as a global script for any AI in the game.
Main function for this "ai.as" are the same as normal ".as" except it can't be "int ego()" but "int id()" instead, use "return 0;" if you want to overwrite any other ".as". "void id()" and "int id()" with "return 1;" are the same.

• Added new struct of background layer with the member ;

C++-Code:

   int32 transparency[30]; // 0x445 | Value   : game.files.get_backgrounds()[].layer[].transparency
   int32 width[30];        // 0x4BD | Value   : game.files.get_backgrounds()[].layer[].width
   int32 x[30];            // 0x535 | Value   : game.files.get_backgrounds()[].layer[].x
   int32 y[30];            // 0x5AD | Value   : game.files.get_backgrounds()[].layer[].y
   int32 height[30];       // 0x625 | Value   : game.files.get_backgrounds()[].layer[].height
   int32 loop[30];         // 0x69D | Value   : game.files.get_backgrounds()[].layer[].loop
   int32 c1[30];           // 0x715 | Value   : game.files.get_backgrounds()[].layer[].c1
   int32 c2[30];           // 0x78D | Value   : game.files.get_backgrounds()[].layer[].c2
   int32 cc[30];           // 0x805 | Value   : game.files.get_backgrounds()[].layer[].cc
   int32 animation[30];    // 0x87D | Counter : game.files.get_backgrounds()[].layer[].animation
   int32 rect[30];         // 0x8F5 | Value   : game.files.get_backgrounds()[].layer[].rect

• Added new struct of weapon_strength's entry with the member ;

C++-Code:

   int32 dvx;        // +0x00 | Value : game.objects[].data.strength.entry[].dvx      / game.files.datas[].strength.entry[].dvx
   int32 dvy;        // +0x04 | Value : game.objects[].data.strength.entry[].dvy      / game.files.datas[].strength.entry[].dvy
   int32 fall;       // +0x08 | Value : game.objects[].data.strength.entry[].fall     / game.files.datas[].strength.entry[].fall
   int32 arest;      // +0x0C | Value : game.objects[].data.strength.entry[].arest    / game.files.datas[].strength.entry[].arest
   int32 vrest;      // +0x10 | Value : game.objects[].data.strength.entry[].vrest    / game.files.datas[].strength.entry[].vrest
   int32 respond;    // +0x14 | Value : game.objects[].data.strength.entry[].respond  / game.files.datas[].strength.entry[].respond
   int32 effect;     // +0x18 | Value : game.objects[].data.strength.entry[].effect   / game.files.datas[].strength.entry[].effect
   int8  unkwn1[20]; // +0x1C         : game.objects[].data.strength.entry[].unkwn1[] / game.files.datas[].strength.entry[].unkwn1[]
   int32 bdefend;    // +0x30 | Value : game.objects[].data.strength.entry[].bdefend  / game.files.datas[].strength.entry[].bdefend
   int32 injury;     // +0x34 | Value : game.objects[].data.strength.entry[].injury   / game.files.datas[].strength.entry[].injury
   int32 zwidth;     // +0x38 | Value : game.objects[].data.strength.entry[].zwidth   / game.files.datas[].strength.entry[].zwidth
   int8  unkwn2[20]; // +0x3C         : game.objects[].data.strength.entry[].unkwn2[] / game.files.datas[].strength.entry[].unkwn2[]

AI Mod By Sauce

Mon, 12 Jul 2021 05:39:44 +0200

OK that's me again!Bring a new AI project now

Introduction
A new AI Mod,all character by Sauce.

If you feel that AI is the same as the original, please make sure you have install VisualCppRedist and get ddraw.dll in directory;

AI obey the rules of Chinese;

Easy，Normal，Difficult，CRAZY! for different difficulty:

Easy:For new hands who just enter VS mode and learn the rules .

Normal:For beginners to understand the skills and moves.

Difficult:For skilled experts improve or keep their level.

CRAZY!:FOR BEST OF THE BEST!

Description

AI has been set as close as possible to human beings, but there are still some defects;

EXE edited:

Exe always opens in the centre of the screen
Fast Loading Speed
Faster F2 Pause
F7 Revive in VS Mode (like v1.9/1.9c)
Team Name according to Team colours
400 object limit won't crash the game
F7 Revive won't affect Rudolf's Clone

Thanks

Thank Fonix for his testing and suggestions on the template;

Thanks Can,XN,chikasa for testing;

Thanks darkfiren for change the EXE file;

Just cover the original lf2 folder,you can play with original exe.

Programmable AI for Neora

Sat, 03 Apr 2021 11:15:43 +0200

My last output is already a bit older, therefore: Now AI support for Neora!

Since there is no real support so far, I was asked if I could take it on.

Description

In the past, people have managed to write AI themselves (see, for example, YinYin's tutorial on how to get started). However, this has never worked in a modified EXE, such as for Neora. I have adapted the code of Silva/Boop/Doix and SomeoneElse and the extension of zort so that "all" hex addresses are correct. ( To be honest, a few addresses are still missing, but these should not be essential for now. )

Source Code

This project is open source, so anyone can look at the modified code.

Source Code on GitLab

Download

On the same page of the source code you can also find the download links. Make sure that you do not download the source code, but the compilation.

Release List on GitLab

Breaking Changes

There is one change that unfortunately can not be done otherwise. For AIs to work for Neora, the call to

game

must be changed to

gamePtr.game

.
Furthermore, not a breaking change, but quite important: Neora supports 1000 objects, instead of 400, so if you find a for loop that goes to 400, just expand to 1000.

Version

The current version is 1.0.1.

Credits

Big thanks to the preliminary work of Silva/Boop/Doix and SomeoneElse. (Thread)
Big thanks to zort for the enhancements. (Thread)
Big thanks to seikosantana for the compilable AI version (Thread).
Also a thank you to Nakato for queries about Neora and offering help!

A new AI template

Tue, 11 Aug 2020 12:15:46 +0200

A new template AI,he can Dodging,defense or rebound ball,weapons,defense basic attack.Drink milk or beer when he had very little HP or MP,get far from enemy while they are lying,countermeasure and defense those melee attack,and most important,dash attack and punch.
I'll use this in LF2 Timelapse.

Edit:It's all finish now!He can beat a Fighter!

Hello everyone!

My name is Sauce, a player from China. This is my first post in the forum.

Two months ago, I finished lots of characters with angelscript AIs, including Firen, Louis, Rudolf, Deep, Firzen, Julian and minions. Also combined it with other authors' great work. Then, I decide to make it public now.

Deep is my first AI,and Firen is my experimental one,so they don't behave well.
My proud and favorite work is Rudolf,it takes me about one month to correct it,test it with all other AIs and myself more than 50 times,and be sure it can win most of the matches,so I think you can enjoy it!
By the way:while Rudolf use clone,it's going to be very spectacular!

DEFENCE FOREVER - AI CRUSHER (YinYin's)

Thu, 02 Jul 2020 09:27:40 +0200

Edited Post--------------------------------------------
I found the main problem.
I'm felling so dumb. It's just an itr/kind that's sticked to the chars and isn't listed in AI-code to ignore.
I gonna let the original post below to help someone who found the same problem i has bevore (but if the community prefer, i will delet it)

Original Post--------------------------------------------
Nithin6777 just posted the problems he's having with YinYin's custon AI (CRUSHER 1.0, for Davis) and I am in great difficulty too.

THE CASE:
Davis simply remains pressing Defense forever.
I'm using an EXE with HEX edition, but i also already edited the script and removed any condition command with "D ();". I also tested this EXE without all my HEX edition in AI code. No result at all...

I usually search the forum a lot and prefer to solve the problem by my own (in addition to the great help that the forum already provides), but again... I didn't find anything about it.
Would anyone know the cause?

OBS:
I tested AI-CRUSHER on the original and it seems to work...
I dont want to build AI using ASSEMBLY. Too hard and takes too much time _>" title=">_>" class="smilie smilie_76" />

YinYin's Crusher AI

YinYin Crusher AI isn't activating. Statement in console windows(black board thing):

Anyone have any idea to fix it???

Very basic ai and wait value

Sat, 21 Mar 2020 22:11:36 +0100

Finally I have a use for ai script within my coding abilites aand it doesn't work.

Code:
int ego(){
 if (mode == 1 && self.hp < 50 && self.hp > 0 && self.frame == 230 || self.frame == 231){
  DJA();
 }
 return 0;
}

Basically hunter suppose to use DJA while lying and his hp is lower than 50, and make it happen only in stage mode. There is no any errors in console, yet he's transforming pretty much anytime you send him lying, also in vs mode.

And for second part of this thread, is there a way to make ai wait a bit before performing move? I can't split lying frame into two parts, because using next: in state 14 makes character start blinking, even if another frame also use state 14. So no simple dc solution.

Sauce's Rudolf AI

Wed, 13 Nov 2019 09:54:38 +0100

This is a recently created AI by Sauce(一桶酱油), who is from the chinese community. I'm posting on his behalf.

This is a VERY tough "void id" AI for Rudolf, not unlike what YinYin had done with Crusher Davis.
It is not designed to dodge ranged attacks however, but good luck trying to take him down in melee combat.

Save the following code below as "5.as".

AI Script Engine 2.32

Sat, 05 Oct 2019 14:41:24 +0200

This is totally not a new thing. It's zort's fork (https://www.lf-empire.de/forum/showthread.php?tid=10945).
Links to DLLs, in case you only need DLLs, not sources:
Debug, for developing AI scripts,
Release, if you only want to play with custom AIs.

I made a new repository for this, https://github.com/seikosantana/lf2-ai-scriptengine
I didn't change anything in code. It was a clone of zort's repository. I added angelscript.lib (by compiling AngelScript SDK) and also added angelscript.h header so now it should compile without missing files. See readme in the repository for more info.

What you can't do on previous ddraw is setting a target as an enemy.
loadtarget does not set them as enemy. It loads information about the target instead.

So what's new?
This version has improvements, enables setting target as enemy (setEnemy(int)). An example by the original author:

Spoiler (Click to View)

Backward compatible with previous AI scripts? Yes so far. All my old AI scripts builds and runs without problems.
(Let's migrate to this version of ddraw wrapper )

Github repository, made some minor improvements

Wed, 21 Nov 2018 03:54:56 +0100

There were some changes I wanted to make. To share them, I put them in a github repository: https://github.com/zort/lf2-ai-scriptengine Can consider this zort's fork until Silva or SomeoneElse give their approval I guess.

Here's the list of changes:

Upgraded to Angelscript 2.32.0 (mainly for array.sort() that takes comparator function)
Added Object.vrests (was split into int vrest and char unkwn8[396])
Added global elapsed_time (number of TUs since start of match)
Added vector3 type
Copy more fields from Object to Info (the self and target globals):
- x_real, y_real, z_real
- vector3 position, velocity
- wait_counter (also fixed offset in Object, previously was 4 bytes off, as was ctimer and ccatcher)
- weapon_holder
Added function setEnemy(int) for use in ego() for setting the enemy that the AI targets when you return 0 from ego() (in fact I initially thought this was what loadTarget did) - though it's only as useful as ego() is, which at the moment is not very useful because it's limited to basic Template AI
Fixed signatures of Info constructors, now you can construct an Info via Info(object_num) (useful because unlike Object, Info stores its own num and other goodies)
Made Info fields changeable (non-const), now you can do like obj.frame = obj.data.frames[obj.frame].next to simulate obj in the next TU
Added enum ItrKinds:
Spoiler (Click to View)
KIND_NORMAL = 0,
KIND_CATCH_DOP = 1,
KIND_PICK_WEAPON = 2,
KIND_CATCH = 3,
KIND_THROWN = 4,
KIND_WEAPON = 5,
KIND_FINISH_HIM = 6,
KIND_ROWING_PICK = 7,
KIND_HEAL = 8,
KIND_SHIELD = 9,
KIND_FLUTE = 10,
KIND_FLUTE_2 = 11,
KIND_OBSTACLE = 14,
KIND_WHIRLWIND_LIFT = 15,
KIND_WHIRLWIND_FREEZE = 16,

Here's the DLLs: debug, release

Everything is backwards compatible of course, or at least it should be.

To show some of the new features, here's a script that always targets the nearest enemy (gets very confused):

AI-Code:

double distance_to(const Info& other) {
    return (self.position - other.position).length();
}
 
bool closer(const Info& a, const Info& b) {
    return distance_to(a) < distance_to(b);
}
 
array<const Info@> getEnemyObjects() {
    array<const Info@> ret = {};
    for (int i = 0; i < 400; i++) {
        // exists
        if (!game.exists[i])
            continue;
        // not us
        if (i == self.num)
            continue;
        // is enemy
        if (game.objects[i].team == self.team)
            continue;
        // is alive
        if (game.objects[i].hp <= 0)
            continue;
 
        ret.insertLast(Info(i));
    }
 
    return ret;
}
 
array<const Info@> getEnemies() {
    array<const Info@> enemyObjects = getEnemyObjects();
    array<const Info@> ret = {};
    for (uint i = 0; i < enemyObjects.length(); i++) {
        // is human
        if (enemyObjects[i].type != 0) 
            continue;
 
        ret.insertLast(enemyObjects[i]);
    }
 
    return ret;
}
 
array<const Info@> attackableEnemies() {
    array<const Info@> enemies = getEnemies();
    array<const Info@> ret = {};
 
    for (uint i = 0; i < enemies.length(); i++) {
        if (enemies[i].state == STATE_LYING)
            continue;
 
        if (enemies[i].blink != 0)
            continue;
 
        ret.insertLast(@enemies[i]);
    }
 
    return ret;
}
 
array<const Info@> attackableEnemiesByDistance() {
    array<const Info@> attackable_enemies = attackableEnemies();
    
    attackable_enemies.sort(function(a,b){return closer(a,b);});
    
    return attackable_enemies;
}
 
int ego() {
    array<const Info@> enemies = attackableEnemiesByDistance();
    if (enemies.length > 0)
        setEnemy(enemies[0].num);
 
    return 0;
}

ego() messes up stock AI

Mon, 12 Nov 2018 20:49:19 +0100

The following AI script should have no effect on the AI:

Code:
int ego() {
    return 0;
}

However, it completely changes the AI. It's most noticeable with Julian (and other locked characters, though I only tested Justin), because he doesn't use any special moves. It's like he's using Bandit's AI. Here's how he behaves with the above script:

https://my.mixtape.moe/zbazcy.mp4

For reference here's how he behaves normally:

https://my.mixtape.moe/akfnzo.mp4

I'm using ddraw.dll version 2.2

ai for any char

Sun, 11 Nov 2018 04:19:44 +0100

Finally i am on the lfe forum, for so long i was having problems with registering on this forum, but i am now here to give lf2 chars human thinking ai to defeat any human player and also to do more things. Now this is the ai i have been making for int ego ai, about dodging attack which is very simple:

AI-Code:

int ego(){

down(1,1);return 1;
}
if (target.state == 3 && abs(target.z-self.z) > 19

up(1,1);return 1;
}
 
return 0;
}

So now you can select it and copy and paste it to try it out for any char.
