C++ (Cpp) ParameterInstance::getValue Examples

Example #1

File: FMODAudioComponent.cpp Project: azarus/ue4integration

float UFMODAudioComponent::GetParameter(FName Name)
{
	float Value = 0.0f;
	float* StoredParam = StoredParameters.Find(Name);
	if (StoredParam)
	{
		Value = *StoredParam;
	}
	if (StudioInstance)
	{
		FMOD::Studio::ParameterInstance* ParamInst = nullptr;
		FMOD_RESULT Result = StudioInstance->getParameter(TCHAR_TO_UTF8(*Name.ToString()), &ParamInst);
		if (Result == FMOD_OK)
		{
			float QueryValue;
			Result = ParamInst->getValue(&QueryValue);
			if (Result == FMOD_OK)
			{

		if (Result != FMOD_OK)
		{
			UE_LOG(LogFMOD, Warning, TEXT("Failed to get parameter %s"), *Name.ToString());
