Empty Array of IMotionControllers for Unreal using Oculus Quest
The typical way of setting up a MotionController in Unreal Engine is through Blueprints, but I'm trying to identify different types of motion controllers for various VR setups and from there apply the orientation and position data. I have no problems getting Oculus Rift and Vive controllers and trackers using C++, but on Oculus Quest the array that's populated with IMotionControllers is empty when debugging over ADB. Why might this be? The following code will print a length of 0 on Oculus Quest only. const FName feature = FName(TEXT("MotionController")); TArray<IMotionController*> controllers = IModularFeatures::Get().GetModularFeatureImplementations<IMotionController>(feature); UE_LOG(LogGloveController, Warning, TEXT("Number of Controllers: %d"), controllers.Num());
Detecting which controllers are plugged in
I'm currently working on detecting plugged in controllers for Oculus Rift and also for Oculus GO. Here is function that I've come up with: (it's added to the OculusInput.cpp) FString FOculusInput::GetPluggedControllerName() { FString ControllerType = "None"; ovrpControllerState4 OvrpControllerState; if (OVRP_SUCCESS(ovrp_GetControllerState4(ovrpController_Active, &OvrpControllerState))) { switch (OvrpControllerState.ConnectedControllerTypes) { case ovrpController_Touch: ControllerType = "Oculus_touch"; break; case ovrpController_Gamepad: ControllerType = "Gamepad"; break; default: ControllerType = "Default"; GEngine->AddOnScreenDebugMessage(-1, 5.0f, FColor::Red, FString::FromInt(OvrpControllerState.ConnectedControllerTypes)); break; } } return ControllerType; } It works well when i have only one of them plugged in, it will never work if i have both touch and gamepad plugged in my pc. My queston is if it's there any way to split that? Do i have to just check those hexadecimal values before? Also how can i detect if it's Oculus GO controller?
