Tutorial How to make AI learn every ability for Heroes

[Dregonx]

This is going to teach you how to enable your AI to learn every ability for heroes, including trigger based spells. Up to all 4 normal hero abilities will be learned by a random integer, and the ultimate one will be learned automatically over the others as soon as it becomes available by checking the level requirement in the conditions. This is very good if you have a melee map where the level limit is passed level 10, it'll keep leveling all the skills for whatever hero continuously until they've been maxed out.

(When adding in triggers from this, change the Bold letters to whatever it's talking about.)

The first thing you need to do, is create an integer variable called AiAbility<NameOfYourHero> (Or whatever you want, but it'll be easier to understand this way.) and you do not want to give it arrays. (Do this for each hero you want to do this for and repeat the following for each hero.)

Next create a trigger called <NameOfYourHero> AI Ability

If your in a game where you have pre-placed heroes, then;

Make the event this:

[B]YourHero[/B] AI
    Events
        Unit - [B]YourHero[/B] <gen> Gains a level

If your in a game where you choose a certain hero from say a tavern or whatever, then you'll do this for the event(You'll have to set a variable in the beginning for each player's hero, Unit Types do not work! So you'll have to use Unit instead, arrays are safe for hero unit-setting variables.):

[B]YourHero[/B] AI
    Events
        Unit - A unit Gains a level
    Conditions
    (Leveling Hero) Equal to [B]YourHero[/B]

Now, that you've got the first part down, this will activate every time they level up so far, but it's not enough to level skills properly, because if you happen to level up more then once(say you go from level 1 to 3 instantly), the trigger can sometimes not fire off correctly.

To solve this, heres what you do next for the actions(Must be in this specific order!):

Actions
    For each (Integer A) from 0 to (Unspent skill points of [B]YourHero[/B] <gen>), do (Actions)
        Loop - Actions
            If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                If - Conditions
                    (Hero level of [B]YourHero[/B] <gen>) Greater than or equal to [B]#LevelOfUltimateAbility[/B]
                Then - Actions
                    Hero - Learn skill for [B]YourHero[/B] <gen>: [B]YourHeroUltimateSpell[/B]
                Else - Actions
                    Do nothing
            Set [B]AIAbilityYourHeroName[/B] = (Random integer number between 1 and 4)
            If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                If - Conditions
                    [B]AIAbilityYourHeroName[/B] Equal to 1
                Then - Actions
                    Hero - Learn skill for [B]YourHero[/B] <gen>: [B]YourHeroSpell1[/B] 
                Else - Actions
                    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                        If - Conditions
                            [B]AIAbilityYourHeroName[/B] Equal to 2
                        Then - Actions
                            Hero - Learn skill for [B]YourHero[/B] <gen>: [B]YourHeroSpell2[/B]
                        Else - Actions
                            If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                                If - Conditions
                                    [B]AIAbilityYourHeroName[/B] Equal to 3
                                Then - Actions
                                    Hero - Learn skill for [B]YourHero[/B] <gen>: [B]YourHeroSpell3[/B]
                                Else - Actions
                                    If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                                        If - Conditions
                                            [B]AIAbilityYourHeroName[/B] Equal to 4
                                        Then - Actions
                                            Hero - Learn skill for [B]YourHero[/B] <gen>: [B]YourHeroSpell4[/B]
                                        Else - Actions
                                            Do nothing

Remember, just change the Bold into what yours is, and it's all set, this is highly recommended that a condition to activate this trigger is in the initialization, or a 5 second startup like this:

Player AI Initilization
    Events
        Time - Elapsed game time is 5.00 seconds
    Conditions
    Actions
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            If - Conditions
                (Player [B]#[/B] ([B]Color[/B]) controller) Equal to Computer
            Then - Actions
                Trigger - Turn on [B]YourHero[/B] AI <gen>

Otherwise, you'll be playing the game and the trigger will be learning your skills for you at random. (Make sure you turn off the trigger so it can be re-turned on if that specific player is being used by a computer.)

Also, if you make another trigger where the game starts up, and runs the trigger automatically(since they have to level to fire it) it'll make them learn their level 1 skill at random to start out with.

Events
    Time - Elapsed game time is 5.00 seconds
Actions
    Trigger - Run [B]YourHero[/B] AI <gen> (ignoring conditions)

If you can't get over the fact at how sometimes(After it's out of skills to level up for what it's trying to level up.)
Then just change the event to:

Time - Every 1.50 seconds of game time

Hopefully this helped someone. :thup:

good tutorial but needs a demo map!
+rep for effort!
