2:09:56frostyninja Q: So, instead of tags, why not relegate the logic of picking a range, or random bunch, of specific assets to the part that pulls assets in - e.g. when making a new entity or what have you, have a way to specify hey pick one from these specific assets here (by path / name or some other identifier). Obviously comes with its own issues, might not be what you want, and all but is it an idea you've entertained?

Do you see any problems with this, and / or how do 2D animation system normally know which sprite to grab?
