This video will teach you how to save and load your unreal engine 5 game in the most scalable and flexible way. I aim to teach you good code architecture and how to structure your systems in a way that makes them easily reusable, maintainable and scalable.

By the end you will have a system that contains a reusable save and load system that can be copied into any project, and extendable with custom save functions for a specific project.

The common BPI_SaveGame interface functions for any project are (LoadGameData, SaveGameData, and GetGameData) these can be used as is, then for each different project you can simply implement additional custom functions (Like the SavePlayer and SaveCubes that are specific for this project)

About me:
I've been learning game development for a few years now, I do have a background in software engineering, and I also have a background in education, so being able to combine my love of gaming, software engineering and education is the best way to spend my time.

I am currently working on a few unreal engine games as a hobby, but I am also trying to build a community, thus I am creating YouTube tutorials to find others who are interested in game development and design.
