Add buffs to units via triggers

[Chewii]

So is there a way of doing this? I guess you could make a dummy unit and make it cast a spell which will put a buff on the target.
But I want to add it via triggers, GUI or JASS doesn't matter.

No, you cant add buff, you should make it work with the spell by casting the spell, it will add the buff. In triggers, you can only remove buffs but you cant add one in triggers.

UnitAddAbility
Idk if this works though,because UnitRemoveAbility works for removing buffs(buffs are abilities, type buff extends ability

//===========================================================================

function UnitHasBuffBJ takes unit whichUnit, integer buffcode returns boolean

    return (GetUnitAbilityLevel(whichUnit, buffcode) > 0)

endfunction



//===========================================================================

function UnitRemoveBuffBJ takes integer buffcode, unit whichUnit returns boolean

    return UnitRemoveAbility(whichUnit, buffcode)

endfunction

You may use an aura ability though and give it to the target directly to avoid having dummy units and ordering casts.

@Almia: No. Buffs inherit the behaviors of the ability they were casted through, which is probably a reason why there is no simple UnitAddBuff function. You would not have options how the buff would react to different events like unit death for example.

Make a dummy unit cast a sell in the target unit and stack the buff.

Well another idea is that Using a spell that gives buff,cast it,then remove it.You can do it in triggers.
Another idea is using an aura type spell.Put it inside a dummy spell book. Add the ability Dummy Spellbook,then disable it via Player - Disable Ability.

You do not even need a spellbook. Most people use the Tornado Slow Aura which does not possess a button in the command field.

Im not familiar with Wc3's abilities so that will be better.

The aura thing was pretty interesting. But I think i'll stick with the dummy unit

I think it would be better if you follow WaterKnight's suggestion
