How is DOTA AI Created?

 

[ShadowFlare]

By hard work.

 

[puggsoy]

To be precise, if you want to make AI similar to that in DotA, you'll have to study AI and triggers. Depending on the kind of map you're making you'll need to use one of those.

In short, as forsakener said, it is hard work. If you were expecting to get a simple answer written out that you could copy and paste, well... sorry.

 

[Admiral Jack]

Well im not that kind of man always copy and paste of course i just wanna ask if they are made of AI Sripts or Triggers.... Thanks guys ...

 

[Crazed_seal2]

If your talking about the monsters that spawn from the bases.

Its actually quite simple.

They are pretty much told to move to certain points.

And if they find something hostile they will attack it.

 

[puggsoy]

Well, yeah.. if that's the case then I would guess it is quite simple... and since I know nothing about non-trigger AI myself, I'm gonna go ahead and assume that it's done with triggers.

If that's so, then it'd go something like this, I think:

• Simple AI
  • Events
    • Time - Every 300.00 seconds of game time
  • Conditions
  • Actions
    • Unit - Create 1 Necromancer for Player 2 (Blue) at ((Center of (Playable map area)) offset by (0.00, 10.00)) facing Default building facing degrees
    • Unit - Order (Last created unit) to Attack-Move To (Center of General Attack Region <gen>)
    • Unit - Create 3 Ghoul for Player 2 (Blue) at ((Center of (Playable map area)) offset by (0.00, 10.00)) facing Default building facing degrees
    • Unit - Order (Last created unit) to Attack-Move To (Center of General Attack Region <gen>)

That's just a simple example, but it basically emulates what DotA does, afaik.

why not ask the one who made the AI versions himself...

anyway, its just a mass of triggers setting the behavior of the heroes... you just need a bit of hard work in order to create different possible behavioral patterns for each hero...

 

[mckill2009]

triggers, it's always trigger for a good AI...the only thing I cant do is for the AI to buy/sell...

I believe that you will have to learn vJass and how to make it as oficiant as posible or something to do AI for the extra functions and efficiency or otherwise with just GUI it may lag caused my how much script the game will have to go through to get what it wants(if you want a complex AI that does whatever you want as a normal person will play or close to it).

 

[Admiral Jack]

Can anyone make a AI in Jass that make the AI use spells in general.......

 

[Adiktuz]

AIs are too much map specific, that's why no one makes a system resource for that...

unless you want some very stupid AI which just brandishes spells once it receives damage...

@ mckill2009
Thanks my friend will you help me in my Hero Defense map.....
im just alone making it it would be better that someone will help me.....
Thanks.....

 

[Magtheridon96]

It takes days of work to create an AI for ONE hero

 

[Bribe]

As someone said earlier, DotA basically uses attack-move. Just consult a simple Tower Defense tutorial and that will get you perfect DotA-style "AI".

can you make it to me too? XD my map is an hero arena

 

[Adiktuz]

if he does that, it would either:

Greatly slow him down

or

Greatly reduce the quality of the AI

Lol! No, your wrong, it will...
Greatly slow me down

AND

Greatly reduce the quality of the AI

I think that these are the most common used triggers in AI

• Events
  • Unit - A unit Is issued an order with no target
  • Unit - A unit comes within XXX.xx of UNIT
  • Actions
    • Unit - Order UNIT to Move To Point
    • Unit - Increase level of ABILITY for UNIT
    • Hero - Learn skill for UNIT: ABILITY
    • Hero - Create ITEM and give it to UNIT
    • Unit - Order UNIT to GROUND USE ABILITY POINT
    • Unit - Order UNIT to UNIT USE ABILITY UNIT
    • Unit - Order Button UNIT to Attack UNIT
