Exploring Game Saves: JSON # 2 Arrays | Game Dev Tutorial

Episode 2 of Exploring Game Saves dives into saving game data with JSON in Unreal Engine, all through Blueprints—no coding required. We’re still building our JSON system but we’re going down the rabbit hole of json arrays and nested elements. This is good for understanding both the importance of data structure and an example of actually how to stack JSON objects in unreal to get the array output.
