This Unreal Engine 5.4 video is about creating a Custom Game User Settings Class.
We start by talking about how the Game User Settings class is used, and how it works. Next, we create the TD Game User Settings C++ Class and add three Volume Properties with Getters and Setters. Following that, we complain about the current state of Visual Studio for Unreal and how the suggested fix is a bad idea. After that, we add our TD Game User Settings to the DefaultEngine.ini file so it gets used in the Editor, and then in the Editor, we create a Utility function to Cast to the TD version of the Game User Settings. Lastly, we go through some scenarios where a value is set and why it might not be saved, and how to resolve those issues.
