[Trigger] Detecting if unit has ability/buffs

Is there a condition that checks if a unit has an ability?
The only solution to this I see is to do this:

If - Conditions

((Triggering unit) has buff P ) Equal to True

But I want something like this:

If - Conditions

((Triggering unit) has ability P ) Equal to True

Though, I don't think that that is an option. So I made all the abilities I wanted auras, made them only target self, and made it try to detect it the first way. But the problem is that the aura's don't give the units the buffs, so the triggers are useless. Any body know the problem or an alternative solution?

In JASS you can simply do GetUnitAbilityLevel( unit theUnit, integer abilCode )

if that returns a number greater than 0, then the unit has the ability (or buff actually. The GUI actually converts the "Has Buff" to GetUnitAbilityLevel, just using the buff code as the abilCode (I guess when a unit has a buff, they are treated as having that "ability". I don't know).

Hope that helps.

There is one you could do...
(I may not post it with right gui-look)

You can find it under the integer condition section

If - Conditions

(Level of "Your Ability" for "unit" is greater than 0)

If the unit would not have the ability, it will always result to zero, thus a similarity to "false"

Haha! it worked! +rep man! you solved all my problems!
