Help with error terms

[RavenCurow]

So I'm trying to update the nomads as a pet project and I'm getting an error that I'm not sure what it means. It says a funtion being called in the nomadunits.lua is ambiguous in class definition. When I look at the line specified I can't see anything wrong with it. So I'm just wondering what it means when it says the function is ambiguous in class definition.

[CookieNoob]

I guess it means that the function is declared twice

[RocketRooster]

Does LUA have prototype overloading?

[Uveso]

I dont know, why you get this error, but its from the function InsertIndexFields() inside class.lua

Maybe your are defining a class twice ?

[RavenCurow]

No, the function isn't being called twice far as I can see. At least not for the same unit type. It's calling the OnTransportAttach function for the hover unit.

[Uveso]

Well, then i don't have a clue whats going on there

[RavenCurow]

I wonder if it's because the exphover unit is calling the nhoverunit class in the same lua as the nhoverunit. Only thing I can think of.

Here is the error log for the function. Now that I look at it, perhaps its not the nomadunits.lua that its saying has an ambiguous function and the default units file itself.

[Uveso]

I am sorry still no clue.

[Crotalus]

Check if the unit is a descendant of AircraftCarrier / AirTransport / BaseTransport (they are defined in defaultunits.lua) but also has OnTransportAttach defined somewhere else in its class or another parent class of it.

The problem is that some units are inheriting two classes which can cause this error.
