you have to declare some generic type doMove<Something> which isn't even used

[uli]

Haven't tried, but how about:

KClass<out T>? = null as KClass<Queen?>)

[loloof64]

Yes, will try it right now

[kirillrakhman]

@uli this is not type safe

[loloof64]

Ok. So I forget about this solution

[kirillrakhman]

what if you call doMove<King>() and don't pass a class?

[kirillrakhman]

there's a reason this is not compiling

[uli]

i did not try. traveling on a train currently 😉

[kirillrakhman]

please don't to this, you will run into type issues

[loloof64]

Ok. I forget about nullable way

[uli]

or simply use this oveload:

fun doMove(startSquare: Pair<Int, Int>, endSquare: Pair<Int, Int>): ChessGame {
    doMove(startSquare, endSquare, null as KClass<Queen>)
}

[loloof64]

Thanks, but I did rather go into the following

[loloof64]

fun doMove(startSquare: Pair<Int, Int>, endSquare: Pair<Int, Int>): ChessGame{
        return doMove(startSquare, endSquare, Queen::class)}

fun <T> doMove(startSquare: Pair<Int, Int>, endSquare: Pair<Int, Int>, promotionPiece: KClass<out T>): ChessGame where T: ChessPiece, T: Promotable {
