System: Engage System v3.2
Created by: Mckill2009

This system is for AI usage, just like DotA AI.
Read the instructions carefully inside the code.


JASS: 
/*
===================EngageSystem v3.2===================
==================Made by: Mckill2009==================

FEATURES:
- This system will order a unit to engage and search for enemies
- Allows attack captain (hero leads the attack)
- Allows pick up item
- Allows target random enemy units include creeps and buildings
- Option to retreat away from attacker or to building when HP is low
- Allows target refresh when duration runs out

HOW TO USE:
- Make a new trigger and convert to custom text via EDIT >>> CONVERT CUSTOM TEXT
- Copy ALL that is written here (overwrite the existing texts in the trigger)
- Make a dummy ability of UNHOLY FRENZY that has no buff, mana cost and replace the SPELL_ID raw code
  written below the THIRD global block if needed, see below the SPELL_ID for more info.

KNOWN ISSUES:
- This system does not support Buy and Selling of items for AI

REQUIRES:
- Jass New Gen Pack (JNGP) by Vexorian
- GetClosestWidget by Spinnaker
- IsUnitChanneling by Magtheridon96
- RegisterPlayerUnitEvent by Magtheridon96

Parameter explanation:

1) static method SetEngageUnit takes unit u, boolean attackcaptain returns nothing
This is the FIRST thing you need to do.
attackcaptain - sets the attack captain which will follow/guard heroes or hero that will lead the attack group

2) static method SetUnitPickItem takes unit u returns nothing
3) static method SetUnitRetreat takes unit u returns nothing
Enables Hero to pick items and retreats respectively, these are optional

4) static method SetUnitLockTargets takes unit u, integer targets, real atkdur returns nothing
This is the SECOND thing you need to do, coz engaging must have targets.
targets - Locks a particular ENEMY target
1 to 16 = Targets a specific ENEMY PLAYER
17 = Targets ALL ENEMY PLAYERS
18 = Targets only enemy STRUCTURES
19 = Targets only enemy FLYING UNITS
20 = Targets only enemy HEROES

Take note that the Targets reffers to the MAIN TARGET

atkdur - Sets how long an attacker to lock to a particular target

5) static method SetReturnPoints takes unit u, real xReturn, real yReturn returns nothing
This is the THIRD thing you need to do, the return locations.
Sets and Changes the Return point of the AI if no more targets around

6) static method SetHeroToProtect takes unit follower, unit hero returns nothing
This is optional

7) static method RemoveEngagingUnit takes unit u returns nothing
Removes the Engager from the system

NOTE:
All the u is the unit or the AI that's engaging.

- Initializer replaced by struct onInit
- Added 4 function calling
- Added 1 function to check if the AI is channeling or not
- Added AI engage for summoned units to protect the hero
- Fixed minor retreat point as pointed out by bugers

Setting the target always to the first of the group is going to always pick the unit with the lowest y-coordinate. You should probably use a "GetClosestUnit" function (found under JASS Resources) to make this more modular.

You should also move the "SetupSkillsAndItemTypes" to the top of the script because it is configurable.

You also just need 1 hashtable for this, just use the "-parentKey" or "-childKey" trick I showed you.

I have a few questions:

1. Will the AI cast spells based on channel?
2. Will the AI work on a map in which players control 1 hero and fight each other, there are also a lot of creeps and there is no base (structures) (there are fountains of regeneration though)?
3. Will the AI use the waygate if that's the only way to enter & leave base?

The point of libraries is to have the option to require other needed systems, which should be applied here.

And my eyes hurt every time i see the line "InitHashtable()" - this time twice!

And I also do wonder why this - very important function - is at the bottom of the code? :)

JASS: 
// Set the skills and item types here!
private function SetupSkillsAndItemTypes takes nothing returns nothing
    //You must setup the skills here
    set SKILL[1] = 'A000'
    set SKILL[2] = 'A000'
    set SKILL[3] = 'A000'
    set SKILL[4] = 'A000'
    set SKILL[5] = 'A000'
    //IMPORTANT NOTE: if you increase the item types created, you should increase also the MAX_ITEM_TYPE of the globals
    set ITEM_TYPE[1] = 'will' //Default Wand of Illusion
    set ITEM_TYPE[2] = 'woms' //Default Wand of Mana Stealing
    set ITEM_TYPE[3] = 'wlsd' //Default Wand of Lightning Shield
    //set ITEM_TYPE[4] = 'ADDITIONAL ITEM'
    //set ITEM_TYPE[5] = 'ADDITIONAL ITEM'
endfunction

I added it to the map and it seems I'm in luck, the AIs automatically went to the path where the way gate is and so they went outside of base on their own.

Guess I've found the perfect solution.

EDIT:

I think I found a bug, the units are moving towards the middle of the map every time, and soon it turns into a middle of map massacre and then it repeats.

OK, ok Ima do that, Bribe already said that btw :)...

@Ironside
- I dunnu, maybe AI is programmed to function to find gateways?, in that case good!...
- Ima fix the middle of the map massacre, before I already added a search
and move location but I removed that function, I guess Ima put it again...

EDIT:
===UPDATE===
version 2.0
- Timer loops are replaced by trigger loops
- Single Hashtable usage
- Fixed a bug that caused the units stay in the center
- Added condition structure type not included in the Engage call
- Attacked is replaced by Damage detection for the retreat trigger
- Configurables are placed on top
- Test map added waygates to test if unit will search enemy in that way

Wait! I got it :D
We could create a library that tracks player states (PLAYER_NEEDS_GOLD, PLAYER_NEEDS_ITEM, PLAYER_NEEDS_LUMBER, PLAYER_STATUS_IMBA, PLAYER_STATUS_NOOB, PLAYER_STATUS_NEUTRAL, PLAYER_NEEDS_BUILDING, PLAYER_AGGRESSIVE, PLAYER_DEFENSIVE, PLAYER_RETREATING, etc....)

I could design it when I feel like it :p

We could also create functions like:
call AttemptToBuyItemForHero(whichPlayer,whichHero,whichItemId)
This function would check:
- Position of hero
- Distance from the shop where the item is located
- Gold
etc..

If he's far away and has no gold, the PLAYER_NEEDS_GOLD state would be added
to the QueueQueue right under PLAYER_NEEDS_ITEM
The hero would be issued an order to go farm a bit in some area given in the configuration.
When he has enough gold, his state 'poped' off the QueueQueue, and then, we'd have to issue an order to the shop where this item could be bought.

He'll buy the item, and his player state would be set to something like: "PLAYER_STATE_SCANNING"
Then, we would issue the hero an order depending on his status: PLAYER_STATUS_IMBA, PLAYER_STATE_NOOB, etc..
If he's Imba, we'll execute code written by the user for an imba player :p
If he's Nooby, we'll execute code written by the user for a noob player.
We can give samples too.

I think I'll write this when I feel like it :p

You still need to update this further more. Example Engage towards point?

-Use Bribe's Table system.

-Search hero method doesnt use your UnitAlive function.

-Neither in searchtarget method.

-Use a static if here:

JASS: 
if ENABLE_NEAR_TARGET then

-And here

JASS: 
ENABLE_PICK_CUSTOM_SKILL
ENABLE_PICK_UP_ITEM
if ENABLE_RETREAT then

-You declare this variable in the init method.

JASS: 
local trigger t

and nulls it but still doesnt use it at all.

-Use GroupUtils. Just a tip.

- Engage towards, point?, to the point of the target, if there are no more enemies, it will return to xyReturn...
- I'll apply that table when it has no more issues, although it's not needed...
- Search hero, I didnt notice that :)...
- searchtarget, no need...
- Static ifs next update...
- GroupUtils, nah, no need coz Im not destroying the group nor releasing it...

There are a lot of things which I did not update such as removing the x & y
local from the searchtarget method, and remove this part...
JASS: 
if .follow and not IsUnitType(u, UNIT_TYPE_HERO) then
   call GroupEnumUnitsInRect(bj_lastCreatedGroup, .rct, Filter(function thistype.searchhero))
else
   call GroupEnumUnitsInRect(bj_lastCreatedGroup, .rct, Filter(function thistype.searchFarTarget))
endif
set .target = FirstOfGroup(bj_lastCreatedGroup)

and just replace it with ".target=null" since it's useless coz that will be enumerated when target=null, but Ima test it first coz the .follow may have flaws if I do this...

also, this >>> u!=.target is wrong, it should be .target != .target, since "u" picks many, not only one...

I have issues regarding invisible units, the AI will stick lock to that target,
IDK why, but since .target != .target is there, it will lock a new target...

I imported this system to my map. And for realistic terms, the AI is just
attacking random enemy heroes even with fogs. I know they're computers but
I think its unfair to have that advantage.

Is it possible that AI roams the map until it detects enemies then it will attack?

Nice AI system. I am now creating clever AI for my map and use this system as a ground for futher work. But there were some problems also) I think, that it would be useful to add 1 function, which will turn off AI, even when the unit is still alive. May be some mistakes, but i did it so:

JASS: 
public function StopAI takes unit u returns nothing
        call GroupRemoveUnit(ENGAGE_GROUP, u)
        set GROUP_COUNTER_ENGAGE = GROUP_COUNTER_ENGAGE - 1
        call FlushChildHashtable(HASH, GetHandleId(u))
endfunction

And 1 more issue. Is it possible to order them to atack ally unit?
AH, finaly 5/5 :D

Gotta love someone finally pointing out how to make as awesome AI as in Dota. But on the other hand its all Jass, which I sadly expected.
I'm a great fan of others who make AI, but any chance this to be if nothing else, explained in GUI terms?

hmmm... It must be so?
JASS: 
static method create takes unit u, real x, real y, rect r returns thistype
        local thistype this = thistype.allocate()
        set .hero = u
        set .xReturn = x
        set .xReturn = x
As it is in your code or:
JASS: 
static method create takes unit u, real x, real y, rect r returns thistype
        local thistype this = thistype.allocate()
        set .hero = u
        set .xReturn = x
        set .yReturn = y

There is a little mistake:
Should be:
JASS: 
set .xReturn = x
set .yReturn = y
here:
JASS: 
static method create takes unit u, real x, real y, rect r returns thistype
        local thistype this = thistype.allocate()
        set .hero = u
        set .xReturn = x
        set .xReturn = x
Or sometimes retreat is not working...)

I'm pretty much happy because of you updating the map once in a while.
I'm using this system to my map. In the previous versions, the timer seem to collide
with my other time systems, but It is now fixed I think.

I still don't get it why my AI doesn't cast any spell :(

Thank you for posting that link and for the quick reply! :D
Oh. I have one question. This is going to be off topic.

~ My jasshelper doesn't run. It just saves my map like a normal editor.
That's why I can't test my map and continue updating it.

If you want your units to cast spells, you have to make them do it manually. And also you have to stop AI, as I wrote it higher. I can write here 3 functions to add in the system to stop AI and start it again, but spells conditions you will have to create by yourself.

I'm really a noob in codes but I kinda understand GUI. I guess I really
have to make a GUI trigger to make my AI cast some custom spells of mine
that is because I'm no good with codes. That is an alternative.

Sorry about that. I tried my map again without updating it or creating triggers to make the AI cast custom abilities.

My AI do learn those abilities including passive ones. They automatically cast skills
and I'm really surprised because it would change the whole gameplay as if you were
playing with a real player.

It is unable to make them cast spells while AI in on. You have to switch off it for some time and renew then.
Update: or it works?o_O By me it wasn't working...so that i had to write new code(
