Hi, here is your request, AI System. please give me credits when u use it.

Not to come off as rude, but that system is rather bad. It creates a significant amount of lag (due to the memory leaks).
You will also need dozens of triggers for the items alone.

And the AI isn't very intelligent, which removes the "I" in "AI" :/

sorry hehe im just trying to help ^^

And that's much appreciated!

I'm just trying to say that you could greatly improve that system
I'll post a few examples.

When I said "You will also need dozens of triggers for the items alone", I meant you could easily combine them like this:

Basic item triggers

This sets up the items:

• Setup Items
  • Events
    • Map initialization
  • Conditions
  • Actions
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 900
    • Set AIItemType[AIItemCount] = Boots of Quel'Thalas +6
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 5000
    • Set AIItemType[AIItemCount] = Crown of Kings +5
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 2500
    • Set AIItemType[AIItemCount] = Orb of Frost
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 150
    • Set AIItemType[AIItemCount] = Gauntlets of Ogre Strength +3

This activates when a computer player enters the base:

• AI Buy Item
  • Events
    • Unit - A unit enters Human Base <gen>
    • Unit - A unit enters Orc Base <gen>
    • Unit - A unit enters Undead Base <gen>
    • Unit - A unit enters Night Elf Base <gen>
  • Conditions
    • ((Owner of (Triggering unit)) controller) Equal to Computer
    • ((Triggering unit) is A Hero) Equal to True
  • Actions
    • For each (Integer A) from 1 to AIItemCount, do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Owner of (Triggering unit)) Current gold) Greater than or equal to AIItemPrice[(Integer A)]
          • Then - Actions
            • -------- Computer Player has enough gold --> Buy item --------
            • Hero - Create AIItemType[(Integer A)] and give it to (Triggering unit)
            • Player - Add (-1 x AIItemPrice[(Integer A)]) to (Owner of (Triggering unit)) Current gold
            • -------- Go back to area - removed location leak --------
            • Set loc = (Center of Mid <gen>)
            • Unit - Order (Triggering unit) to Attack-Move To loc
            • Custom script: call RemoveLocation(udg_loc)
          • Else - Actions

Those two triggers are all you need for all items.
You can even improve the AI like this:

Example

• Setup Items
  • Events
    • Map initialization
  • Conditions
  • Actions
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 900
    • Set AIItemType[AIItemCount] = Boots of Quel'Thalas +6
    • Set AIItemHeroClass[AIItemCount] = agility
    • Set AIItemMinLevel[AIItemCount] = 2
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 5000
    • Set AIItemType[AIItemCount] = Crown of Kings +5
    • Set AIItemHeroClass[AIItemCount] = all
    • Set AIItemMinLevel[AIItemCount] = 6
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 2500
    • Set AIItemType[AIItemCount] = Orb of Frost
    • Set AIItemHeroClass[AIItemCount] = intel
    • Set AIItemMinLevel[AIItemCount] = 4
    • -------- --------
    • Set AIItemCount = (AIItemCount + 1)
    • Set AIItemPrice[AIItemCount] = 150
    • Set AIItemType[AIItemCount] = Gauntlets of Ogre Strength +3
    • Set AIItemHeroClass[AIItemCount] = strength
    • Set AIItemMinLevel[AIItemCount] = 1

By adding some conditions in the other trigger, the AI now not only buys items, they also buy items for their corresponding class.
That's the first step to a more intelligent AI ^^
You can also make heroes run when below X% HP (and check whether their resurrection is still in cooldown, or if they still have an ankh, or pehaps a heal-spell).
Your spells are completely random right now, which is really a disadvantage.


A more advanced step is aligning the skills the hero chooses with the items it buys - this requires a very flexible system and is a lot harder, but might be worth it.

In either case: if you at least remove the leaks and make a few triggers more efficient as shown above, then the system is acceptable.
But an AI which leaks just isn't good (we don't want AI's to cause lag, do we?)

Here's some triggers you could use that aren't as complicated as Ap0poo's triggers. I think this is what your lookin for not a complex item system.

Here's your AI movement trigger

Hidden

• Move Ai
  • Events
    • Time - Every 30.00 seconds of game time
  • Conditions
  • Actions
    • Set Random_Loc = (Random point in (Playable map area))
    • Unit Group - Pick every unit in Ai_Units and do (Actions)
      • Loop - Actions
        • Unit - Order (Picked unit) to Attack-Move To Random_Loc
    • Custom script: call RemoveLocation(udg_Random_Loc)

Here's a revive trigger for the AI

Hidden

• Revive Ai
  • Events
    • Unit - A unit Dies
  • Conditions
    • ((Triggering unit) is in Ai_Units) Equal to True
    • ((Triggering unit) is Summoned) Equal to False
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of items carried by (Triggering unit)) Greater than 5
      • Then - Actions
        • Hero - Drop (Item carried by (Triggering unit) in slot (Random integer number between 1 and 6)) from (Triggering unit)
      • Else - Actions
    • Wait 20.00 seconds
    • Set AITempLoc = ((Owner of (Triggering unit)) start location)
    • Hero - Instantly revive (Triggering unit) at AITempLoc, Show revival graphics
    • Custom script: call RemoveLocation(udg_AITempLoc)

And here's a simple item trigger for the AI although apO's is much better

Hidden

• Give item Ai
  • Events
    • Unit - A unit Finishes reviving
  • Conditions
    • And - All (Conditions) are true
      • Conditions
        • ((Triggering unit) is in Ai_Units) Equal to True
        • (Number of items carried by (Triggering unit)) Less than 6
        • (Random integer number between 1 and 2) Equal to 1
  • Actions
    • Hero - Create (Random level (Random integer number between 1 and 7) item-type) and give it to (Triggering unit)

And here's a simple way to make the AI learn spells

Here's a trigger to force the AI to cast certain spells but its not needed.
