Hi. I am trying to bind keys in my player controller but i am getting an unresolved error:

void AMyPlayerController_CPP::SetupInputComponent()
{
	Super::SetupInputComponent();

	InputComponent->BindKey(EKeys::Left, IE_Pressed,this,&AMyPlayerController_CPP::setLEFTOn);
}

void AMyPlayerController_CPP::setLEFTOn()
{
	myLEFT = true;
}

The error i have is this:


  LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl FInputChord::FInputChord(struct FKey,bool,bool,bool,bool)" (__imp_??0FInputChord@@QEAA@UFKey@@_N111@Z) referenced in function "public: virtual void __cdecl AMyPlayerController_CPP::SetupInputComponent(void)" (?SetupInputComponent@AMyPlayerController_CPP@@UEAAXXZ)

I added this line in the build.cs file:

	PrivateDependencyModuleNames.AddRange(new string[] { "Slate" });

How did you know that adding this to the build.cs file would fix the problem?

Thanks so much for posting the solution!
