[AI] How to reference a unit from melee AI script

[Mannoroth]

In the melee AI scripts, you have access to units in general by their ID. Is there any way to convert that ID (ie. obtain) to a "unit" type for use in other functions?

For example, is there a way to reference your hero as a unit instead of simply hero_id ?

I've even tried using GroupEnumUnitsOfPlayer(g, ai_player, filterFunc) but the filter function is never called leading me to assume it is not detecting any units.

Any help would be greatly appreciated.
