Initialize static variables

Hi again! I was thinking more and, sorry, but didn’t catch the “with all the parameters” part. FInputModeGameAndUI has default constructor indeed but not with parameters.

Now I can see - there are 2 options you can do such initialization.

1 - because FInputModeGameAndUI has setters which returns references to itself in cpp file you can do such a thing:

FInputModeGameAndUI UMyClass::MyInputMode = FInputModeGameAndUI().SetWidgetToFocus(nullptr).SetLockMouseToViewportBehavior(EMouseLockMode::DoNotLock).SetHideCursorDuringCapture(false);

2 - you can create a default input mode and init it somewhere in begin play or PostInitProperties:

FInputModeGameAndUI UMyClass::MyInputMode = {};

void UMyClass::PostInitProperties()
{
    Super::PostInitProperties();

    static bool bStaticInit = false; // will be set to false only once
    if (bStaticInit == false)
    {
        bStaticInit = true;
        MyInputMode.SetLockMouseToViewportBehavior(EMouseLockMode::DoNotLock);
        MyInputMode.SetHideCursorDuringCapture(false);
    }
