In this tutorial, I introduce you to Choosers, a new plugin from Unreal Engine that allows you to make robust asset selections based on run-time input data of your game. Whether that means selecting which animations to play, how much damage should be dealt to a character, or what kind of gameplay effect should be applied; it’s crucial that developers construct their data in a way that allows them to easily read and write from it, and to make decisions based on it.
