Add Drag & Drop support to existing Audio Asset

[AdamPoncle]

Currently when dragging audio in the main library manager view, it will always add a new audio asset and add to that (TEMP).

A nice improvement to the workflow would be to add support for adding the audio entity to a selected asset. I have tested the following logic locally and it seems to work.

LibraryWindowManager.LibraryFactory - Update all lines which call CreateAsset(BroName.TempAssetName) to call the following method instead:

private AudioAssetEditor GetAudioAssetEditor()
{
	if (_currSelectedAssetIndex != -1)
	{
		if (_assetEditorDict.TryGetValue(_allAssetGUIDs[_currSelectedAssetIndex], out var editor))
		{
			if (editor.Asset != null)
			{
				return editor;
			}
		}
	}
	return CreateAsset(BroName.TempAssetName);
}

Thanks! That’s a really good idea.
But I might try a slightly different approach to achieve it, because if I understood your method correctly, users might have trouble creating a new asset via drag & drop. That’s due to how Unity’s list behavior works: (sadly) there’s no “unselect” action, so once an element is selected, both _currSelectedAssetIndex and ReorderableList.index won’t go back to -1 unless we reopen the window or enter an asset and return.

Maybe a better approach would be to let users drag audio clips directly onto a specific list element (audio asset). Would that work for your use case?

Hey!

Any approach would be fine, I had not realised about the "unselect" issue.

Alternatively, being able to drag an audio clip when you are inside the Audio Asset view would work just as well (if not better!)
