Hey,
I'm pretty new to C++ so I apologize that this is probably extremely basic. I come from entirely Blueprint programming. I'm trying to add a custom blueprint function that gives me an array of the names of available audio output devices in Windows. But when I add the blueprint function to use it, I get the attached error. I need this function to work in any blueprint class, there is no AudioDeviceOutput class, just the function I'm making.
Here is my code.
header
cpp

Code:
#include "AudioDeviceOutput.h" TArray<FString> UAudioDeviceOutput::GetAudioDevices() { FAudioDevice* AudioDevice = GEngine->GetMainAudioDevice(); TArray<FString> AudioDeviceList; AudioDevice->GetAudioDeviceList(AudioDeviceList); return AudioDeviceList; }
