Gamepad Analog Inputs

With a PS4 gamepad controller I can't get any analog input (-1.0 to 1.0) from the thumbsticks. In the Steam controller mappings I've set the thumbsticks to the joystick mode. For Enhanced Input: I've spawned an actor, enabled the input on it, added an input context with a high priority, removed all other input contexts, but only the keyboard/mouse events are getting through. I've also hooked UPlayerInput::InputKey(), no analog events there either. Am I missing something obvious? What's the next thing to hook?

I know they used to have partially implemented unofficial controller support in like U7 or U8, but they dropped it entirely when they switch to enhanced input. if you can wait until console support (which they are working on) releases, it will probably start working out of the box then

IIRC EnhancedInput is new with UE5, so they had it back in U7 and dropped it in U8

They've somehow managed to break the Enhanced Input itself on purpose. Normally, even if it's not used in the game, you should still get the input in the engine if you bind the events properly. Anyway, if someone can deduce the call stack for the input, it would be useful. I don't see it clearly by just looking at the engine sources. Well, I've ran out of the programming things to do, so I gave it another shot by starting from the lowest level side and while actually believing. And it has turned out to be trivial:

FSlateApplication& SampleObject = FSlateApplication::Get();

Invoke( [&]() {
    HookInvoker<decltype(static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)), static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)>::InstallHook("FSlateApplication::OnControllerAnalog", &SampleObject); \
    return HookInvoker<decltype(static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)), static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)>::AddHandlerBefore([](auto& scope, FSlateApplication* self, FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue) {
        UE_LOG(LogTemp, Error, TEXT("FSlateApplication Key: %s, AnalogValue: %f"),
            *KeyName.ToString(),
            AnalogValue);
    });
} );

FSlateApplication& SampleObject = FSlateApplication::Get();

Invoke( [&]() {
    HookInvoker<decltype(static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)), static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)>::InstallHook("FSlateApplication::OnControllerAnalog", &SampleObject); \
    return HookInvoker<decltype(static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)), static_cast<bool(FSlateApplication::*)(FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue)>(&FSlateApplication::OnControllerAnalog)>::AddHandlerBefore([](auto& scope, FSlateApplication* self, FGamepadKeyNames::Type KeyName, FPlatformUserId PlatformUserId, FInputDeviceId InputDeviceId, float AnalogValue) {
        UE_LOG(LogTemp, Error, TEXT("FSlateApplication Key: %s, AnalogValue: %f"),
            *KeyName.ToString(),
            AnalogValue);
    });
} );

Have to bridge it back to the Enhanced Input directly, or maybe walk up the chain with the hooks to see how to unclog the main path. I feel like if I start using it, they'll instantly release the gamepad support.

I don't think they'll drop the console support update without some kind of warning or announcement on their channel
