Im sorry to dissapoint you all with lack any real updates or effort put in this AI, tho it might seems like we dont care about it. It's actualy very much the opposite.

These early versions of AMAI where merly prototypes to test how strategies work out while the real AMAI was under development. However the real AMAI2 "AI engine" is about to wake up soon so I havent bothered working anything on this old crap and we ar now focusing everything on getting the real one rolling.

It will sadly still be some time at least 2-3 weeks from now before a public version will be seen, but it will be something completely different, especialy from a developer standpoint.
I cant guarantee the new one will be a challenging opponent from the start, thats still uncertain, but it will have a much greater potential to become a real pro beater, that is a fact.

Updated version of Advanced Melee AI 2. 0.23

Design: Zalamander
Lead Programmer: AIAndy

Many new strategies added and more random gameplay.
It will also try to counter what units you build and now builds out to late game.

Uploading three versions:
Normal(None Cheating)
Cheating(Pray you wont go up against zerg)
Developer Edition(DE, For thoes who rather just use the script files)

Enjoy.


We also would like to announce that we seek help if anyone are interested in learning a bit of scripting and have good ideas and motivation to help improve Advanced Melee AI 2, don't hesitate to contact me.
Being good at playing SC2 is also a strong merit.

You dont have to worry about AMAIs development its just that we dont have as goal to be a beta AI here but rather the best AI for the game when its released but will release some newere versions here after just solving a few small problems now. Today most likely.

Normal AI also have vision. It is only faking "scouting".

and THAT's where you are wrong, when it comes to the SC2 AI, and it's whats make it really interesting and original compared to any other RTS AI before it.

Vision disabled SC2 AI doesnt know about anything it havent seen before.
This ofc also makes it very fun and challenging to make a good none cheating SC2 AI.

Original AI of War3 was a disaster.
The cheating difficulty(Insane) got 2x resources but wasnt even noticably harder than none cheating(Normal) becuse it didnt know how to make use of the extra resources.

Sorry for keeping you guys waiting.

We are working hard on a complete remake of the AI system to fit our AMAI design ideas but I think that framework will be finished today and I will start adding a few different tactics.
So hopefully a AMAI2 0.2x within 2-3 days.

No I mean an AI need to be intelligent meaning it need to be able to come up with the best build order for the situation on its own without copy anyone.

the more you try to control what an AI does the wors it gets.

Imagine a real RTS AI that only needs to know what it needs and it will get to this in best possible way becuse it can think out the best way there on it's own. Only then can it start to rival the human mind. This might even invent build orders smarter than any normal player has thought of yet.

This is exactly what wont work. I have been there, done that etc etc. two big reasons.

1. Firstly, copying somones build order, then half way through the AI discovers that the enemy is going a tactic that will totaly own what its currently going for so it need to change. All of a sudden we have mixed 2 half done build orders and end up with something very bad and lots of resources on nothing.

2. AI is blind, it doesnt sit in front of the PC and see stuff like we do, it doesnt know exactly where to place different buildings and why and it doesnt know the shape of the current map since its built in a way that must work on any map. Meaning some good player built supply depots to turtle ramp, the AI end up just building them randomly in the base area for example.
For a blind AI to find the exact spot for turtling with buildings is extremly hard.


To put it simply, what you are thinking of is doing the "A" without the "I".
An AI need to also be Intelligent, not only Artificial.

An AI will never work good playing like a human player simply put.

AIs have different advantages and have to play differently to make use of them but the AI can never compare to thinking like a real human when playing so trying to make an AI that mimics the play of a human usualy just ends in a disaster.

But... AMAI wasn't that good in wc3 T__T

step in the right direction though.

Well it was better than any alternative and let me present you the reason it wasnt good... Tada! Blizzard hardcoded natives full of bugs.

It was basically impossible to create a challenging AI for War3 not only becuse of these bugs but also becuse of the gameplay with so much roleplaying elementas, handing heroes and do creeping.

How hard it's possible to make an AI in Starcraft 2 only time will tell but I can already say now, it has much better potential than the War3 code had plus the simpler gameplay(Build units, kill your enemy) makes it much easier. No creeps, no heroes.

AMAI2 v0.01 Released.
http://www.filefront.com/15733535/AMAI2_0.01.zip/

First simply prototype version, only contains a simple build for each race right now.

from readme:
Designer: Zalamander
Coder: AiAndy

v 0.01 (none cheating)

Experimental first release:
- Simple early mid game builds for all races.
- Enhanced harassment groups.


Next versions plans:
- Better harassment.
- Multiple builds based to counter enemy tactic.
- Better resource/expansion handling.

AMAI2 will have the same goal as our original AMAI for WarCraft 3.
To make an as challenging and unpredictable opponent as possible while remaining as fun as possible to play with and against.

This first version use the state system but enhanced with custom state switches no timer. Future version is going to have many different states to counter different strategies and do state switching based on enemy intell.
