That is the limit of the documentation about it. When I tried to use it, however, the result wasn't what I'd hoped.
Does anyone have more complete documentation about that API function, or know that it doesn't do what I hoped and there is a different one(s) that I should be using? Could it be a data typing issue? I know nothing of how data is typed in LUA or whether it's auto-type-converted as needed.
Lua has no "out" parameters. (Multiple) return values, only.
The link is broken, the truncated text actually replaced by "...", and I didn't understand your final sentence without the context that the forum post might have provided....
I'd probably learn something from this regardless, but a reply to my second post of this in another subforum mentioned the two API calls that I should have been using instead of this one (GetUnitChampionPoints and GetUnitLevel).
