Start building some jank ass system to map synth sound to notes

JerkyTreats

I’ve decided to build this data structure out as naively as possible, the theory being “Get absolute dogshit technically working, then iterate the shittiness out.”

As such:

/**
 * This is some jank. Not pleased at all with this.
 * I'm going to continue on with this until it's end-to-end working though
 * I've decided to go with the most naive possible approach then iterate a better solution
 */ 
TArray<FCheeseKeyData> FCheeseKeyData::GenerateKeys(TArray<UMetaSoundSource*> Sounds)
{
	TArray<ELetsGoMusicNotes> AssumedNoteOrder = {
		C,
		CSharp,
		D,
		EFlat,
		E,
		F,
		FSharp,
		G,
		AFlat,
		A,
		BFlat,
		B,
	};
	
	TArray<FCheeseKeyData> KeyData = TArray<FCheeseKeyData>();
	int CurrentOctave = 1;
	
	for (int i = 0; i <= Sounds.Num(); i++)
	{
		if (i % 12 == 0)
		{
			CurrentOctave++;
		}

		const ELetsGoMusicNotes Note = AssumedNoteOrder[i % 12];

		FCheeseKeyData Key = FCheeseKeyData(CurrentOctave, Note, Sounds[i]);
		KeyData.Emplace(Key);
	}

	return KeyData;
}

The idea is to take an array of 48 sound cues manually connected through a Mapping Blueprint like this:

	UPROPERTY(BlueprintReadWrite, EditDefaultsOnly)
	UMetaSoundSource* C1_Music_Note;
	
	UPROPERTY(BlueprintReadWrite, EditDefaultsOnly)
	UMetaSoundSource* CSharp1_Music_Note;
	
	UPROPERTY(BlueprintReadWrite, EditDefaultsOnly)
	UMetaSoundSource* D1_Music_Note;
	
	//... For four octaves multiplied by 12 notes

And turn each one into a data structure like this:

USTRUCT()
struct FCheeseKeyData {
	GENERATED_BODY()

	UPROPERTY()
	int Octave; 
	
	UPROPERTY()
	TEnumAsByte<ELetsGoMusicNotes> Note;

	UPROPERTY()
	UMetaSoundSource* Sound;

	FCheeseKeyData();
}

It’s janky, I need a better solution. But I figure it’s going to be easier to refactor this jank than it is to try and pontificates Gods own true data structure.

Time will tell if this is true.
