Call a blueprint function that is overloaded?

Hey there,

you can do something like this:

//BlueprintLibrary.h:

UFUNCTION(BlueprintCallable, meta = (DisplayName = "Function Name", Keywords = "Function Keywords"), Category = "Functions")
		bool Function(int32 Foo, TArray<FVector2D> Bar = {{-1,-1}});

//BlueprintLibrary.cpp:

bool BlueprintLibrary::Function(int32 Foo, TArray<FVector2D> Bar)
{
	switch (Bar.Contains(FVector2D(-1,-1)))
	{
	case true: return CppLibrary->Function(Foo);
		break;
	case false: return CppLibrary->Function(Foo, Bar);
		break;
	}
}

I know it is not exactly overloading… but it is a cheap workaround.

hope this helps.

quick edit: I gave the example of an array, but an array can not have a default value. In any other case like below it would be possible:

//BlueprintLibrary.h:

UFUNCTION(BlueprintCallable, meta = (DisplayName = "Function Name", Keywords = "Function Keywords"), Category = "Functions")
		bool Function(int32 Foo, int32 Bar = -1);

//BlueprintLibrary.cpp:

bool BlueprintLibrary::Function(int32 Foo, int32 Bar)
{
	switch (Bar == -1)
	{
	case true: return CppLibrary->Function(Foo);
		break;
	case false: return CppLibrary->Function(Foo, Bar);
		break;
	}
}
