"Buying" Multi Level Abilities

[edit-addict]

I'm trying to do a DotA clone(yes, another one) where you "buy" your abilities from a shop. And using

Fireball Volley
    Events
        Unit - A unit Sells an item (from shop)
    Conditions
        (Item-type of (Sold Item)) Equal to Fireball Volley
    Actions
        Unit - Add Fireball Volley  to (Buying unit)

is sweet for a 1 level ability, but I can't see a way to get 4 levels into an ability
Is there a way to make items avaliable/unavaliable through research? or triggers? or some other way?

Use alot of If/Then/Else functions..

Couldnt you just use the ability items i mean base your item off something like Bash the item that you can buy (If you look in the Object editor im pretty sure you can find it) and change the ability to something else if you cant find it then use lh2705's one i guess like

...
Event - Unit gains a level 
Condition - (Unit of Type) equal to (Blood mage)
               (learned skills) equal to (fireball volley)
Action - For each Interger 1 to 4 do action and the rest i cant remember coz dont have WE but it would be something similar i guess

So you have no idea either....

umm... is there a way of adding a value, say 1, to a variable interger? i thought if i did something like

Immolate
    Events
        Unit - A unit Sells an item (from shop)
    Conditions
        (Item-type of (Sold Item)) Equal to Immolate
    Actions 
        *Add 1 to Variable(Immolatelevel)[or something like that]*
        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
            
            If - Conditions
                       *Variable(Immolatelevel) =to 1*
            Then - Actions
                        Unit - Add Immolate  to (Buying unit)
            Else - Actions
                       *set level of ability(Immolate)to(Interger A(Variable(Immolatelevel)))

*these are my proposed bits of code that i hope is possible*

Nod if you have a clue what I'm talking about.

i dont think you can add varibles like that but have you tried using the items give everything a go before asking again.

I am SOOOO full of myself right now! THIS TRIGGER ACTUALLY WORKS!!! I DONT BELIEVE IT!

Immolate
    Events
        Unit - A unit Sells an item (from shop)
    Conditions
        (Item-type of (Sold Item)) Equal to Immolate
    Actions
        Set Immolatelevel = (Immolatelevel + 1)
        Unit - Set level of Immolate  for (Buying unit) to Immolatelevel

It probably has a memory leak, but i dont care, because it's never cause me a problem in the past...

If Level of <ability> for <unit> equal to 0 then
- Unit - Add <ability> to <unit>
else
- Unit - Set level of <ability> for <unit> to ((Level of <ability> for <unit>) + 1)
