adding abilities with triggers?

Is it possible to add abilities through triggers? I want to be able to add regular unit abilities through triggers not just hero skills. Thanks in advance for any help.

you make sure it starts off so it isnt researched, (meaning if its a new ability you are editing, base it off one that needs to be researched first). Then at the appropiate time, you use:

Player - Set Current Research level of "Tech" to "number"

and it will become researched.

That's a good idea actually, and I might have to do that, but I was thinking is it possible to not have that ability on that hero in the unit editor, but still give it to him with triggers? For example, if I wanted to sell abilities or something at a shop.

That isnt possible.

all abilities must be given to any unit in the editor. Cannot create abilities on the fly. you can however, replace a unit with a new unit that has that ability....

Figures. Thanks guys.

You can sell abilities if you give your hero all the possible abilities from start, and then do that research thing as Dakan suggested you only need a trigger like this:

Event A unit owned by player 1..12 acquires an item
Conditions (Item type of (Acquired item)) Equal to Spellbook
Actions Set current research level for (Owner of (Hero manipulating item)) for *tech* to *level*

I don't know if it's any better than layzie86988's solution but this one allows you to purchase multiple spells with a single character.

yeah, I don't think that would work out the way I want it to. If I give him all the abilities from the start, that fills up all of his skill spots so he can't get hero skills. But thanks anyway.

If you don't want the greyed out icons to appear while not having any you should simply disable all the spells from start and when a player buys a spell book use the Player - Enable/Disable Ability to re-enable the ability.
Once a player has bought more than 2 books you could remove the first spell again so he could have a maximum of 2* learnt spells (so they don't take up the spaces for the hero abilities).

* Why 2? There are only 2 fields not occupied by other buttons. Just set all the custom spell buttonpos to 1,1 - they will automatically fill up the other field if the first one if occupied.

That's awesome! Thank you, that's exactly what I was looking for.

i belive if you disable a ability, you cannot reenable it during the map... but its something to test

I tried it with a couple different abilities and it seemed to work.

in that case good =)

Very. Thanks everybody
