Function AddSpellEffectById

Creates the special effect in point with coordinates (x;y) with Z = 0 using the model file from the Object Editor field of type t from the ability, unit or buff (works with all these types, though the name states it's ability-only function) with raw code abilityId. If this field has more than one effect inside, it will only create the first effect stated in the field, ignoring all others.

Note

To create an effect with a z-position not zero see http://www.hiveworkshop.com/forums/1561722-post10.html.
