buying abilities

buying abilities

i've seen it done in The Great Strategy and a custom hero arena

How do you make it so you can buy abilities from shops???
i thaught of using triggers, but they would be lengthy... and i have a feeling there is another way, can some1 help me out here?

I can't remember off hand how to do it but if you download my map "darthyoda's Alliance vs. Horde"(not my td(but you can download that to if you want )) you will find like 16 diffrent ability that can be bought however they are all used by Items. For example you can buy invis and you hero will become invis but you have to have the Item in your inventory, not sure if this is want you want but it's the best I can do(without triggers).

My current script for ability 'crushing blow' of my actual map, maybe its useful to u, but as u can see its in german

i did this a few times, but as far there is no (working) way to add abilities to hero without using abilities.

The way i used was simply and, as you put it, lengthy:

event: unit aquires item
cond:
start or
itemtype = ability_item_1
itemtype = ability_item_2
...
end or
event:
if itemtype = ability_item_1 then
add (ability_1) to (hero manipulating item)
call makeAbilityPermanent(ability_1)
endif


another way would be with custom code, i guess that would be way shorter, but you would need 2 instead of 1 trigger, but they are way shorter.
I'll write it as good as i can remember the propber jass code:

function init takes nothing returns nothing
//do this for each item/ability you want
//you cannot add more than one ability per item
StoreInteger(<your gamecache>, "Abilities", I2S('your item code here'), 'your ability code here')
//e.g. StoreInteger(udg_gamecache, "Abilities", I2S('I000'), I2S('A000'))
endfunction

function LearnAbilityFromItem takes unit whichHero, item whichItem returns nothing
//i dunno the exact function name, but i hope you understanad what i mean
local ability whichAbility = GetInteger(<your gamecache>, "Abilities", I2S('itemtype of(whichItem)'))
addAbilityToUnit(whichHero, whichAbility)
endfunction

i know i can do it with a trigger for every item and an if/then/else for every level, but i would like a shorter way, and i dont understand JASS, so the whole script with a couple (insert blah blah's here) and a nice explenation... 40ish different triggers would suck.

then your shizza out of luck, O.o u have to understand the triggers, if u wanna use them...

Hence asking for an explanation, incase you dont understand what that is, its basically a lesson, and lord raszul there are multiple levels (like 10) for each ability...

and also would it be any easier to work using tomes? because i think thats what they used (any other item would require inventory space)

I think my script does all that ^^
there might be a shorter way but not a much shorter

true, but i cant read... what looks like german lol
